Question on condensed matter specialty, what is condensed matter?

You should be going to apply for the university, many schools offer the major of condensed matter physics, such as the University of Science and Technology of China. USTC is a sophomore major. The first two years were physics, and in the second semester of the sophomore year, I chose to choose my favorite major, including theoretical physics, atomic and molecular physics, optics, condensed matter physics, plasma physics, particle physics, astrophysics, etc.

The prospects for condensed matter physics are very good, for example, one-third of the people engaged in physics in the United States are engaged in condensed matter physics.

If I want to study condensed matter physics, do I want to study physics? "Of course, condensed matter physics is a branch of physics, of course you have to study physics, your question is too vague, I don't know what "learn physics" means. "Theoretical physics, atomic and molecular physics, optics, condensed matter physics, if I study physics, do I have to study all these disciplines?

Of course not, but many of the basic courses in these different disciplines are the same, and you have to study general physics (mechanics, heat, electromagnetism, atomic physics) and the four major mechanics (theoretical mechanics, electrodynamics, thermodynamics, quantum mechanics) regardless of the major. But different majors have their own professional courses (in the later stage, such as the senior year, you can also choose to learn some of the professional courses of your own major, according to your own professional interests), you only need to study the professional courses of your own major, and you don't have to study the professional courses of other majors, but if you are interested, you can also go, no one will stop you.

If you are a high school student who wants to apply for physics, but you see a lot of majors and don't know how to choose, the general university will not require you to choose a major now, but wait for you to study for more than a year before choosing a major. When choosing a major in college, some schools are divided into more detailed ones, and some schools are more broadly divided.

Undergraduates are generally not divided into such details, and all physics classes are required.

I am the Department of Physics, Harbin Institute of Technology, and within a few years I learned all the mechanical, thermal, electromagnetic, and optical courses (I don't know why there is no acoustics), plus atoms, quantum physics, and all the four major mechanics, and the engineering department focuses on learning optoelectronic detection, engineering optics, spectroscopy (because we focus on light), plus electronic circuits and other ......

It is almost impossible to use this name in the undergraduate stage of condensed matter (except for some schools), and it is necessary to divide condensed matter and other ...... when entering graduate school

The physics department is very difficult, so if you want to think about it before applying for ...... university

Are you in college now?

Condensed matter condensed matter refers to a system composed of a large number of particles with strong interactions between the particles. There are a wide variety of condensed matter in nature. Solid and liquid states are the most common condensed states.

Superfluid, superconducting, Bose-Einstein condensate, ferromagnetic state in magnetic medium, antiferromagnetic state, etc., are also condensed states.

Condensed matter is a state of solid, such as water, at a certain temperature.

Condensed matter physics is a discipline that studies the structure and dynamics of condensed matter composed of a large number of particles (atoms, molecules, ions, electrons) and the relationship between them and macroscopic physical properties from a microscopic perspective. It is an outward extension based on solid-state physics.

In addition to crystalline, amorphous and quasicrystalline substances, the research objects of condensed matter physics also include various intermediate condensed phases from dense gases, liquids, and between liquid and solid states, such as liquid helium, liquid crystals, molten salts, liquid metals, electrolytes, glasses, gels, etc. After half a century of development, a broader and deeper theoretical system has been formed than solid-state physics. Especially since the 80s, condensed matter physics has made great progress, and the research objects have become more and more complex.

On the one hand, the traditional branches of solid-state physics, such as metal physics, semiconductor physics, magnetism, low-temperature physics and dielectric physics, have been studied more deeply, and the relationship between the branches has become closer. On the other hand, many new branches are emerging, such as strongly correlated electronic system physics, disordered system physics, quasicrystalline physics, mesoscopic physics, and cluster physics. As a result, condensed matter physics has become one of the most important sub-disciplines in physics at present, and the number of people engaged in condensed matter research is second to none among physicists, and the number of publications per year is in the leading position among all branches of physics. At present, condensed matter physics is in a flourishing period.

Moreover, because the basic research of condensed matter physics is often closely related to the practical application of technology, the achievements of condensed matter physics are a series of new technologies, new materials and new devices, which play a key and irreplaceable role in the field of high-tech in today's world. In recent years, the research results, research methods and technologies of condensed matter physics have increasingly penetrated and expanded to adjacent disciplines, which has effectively promoted the development of interdisciplinary disciplines such as chemistry, physics, biophysics and geophysics.

Condensed matter refers to a system that is composed of a large number of particles and has strong interactions between the particles. There are a variety of condensed matter substances in nature.

Classification of condensed matter physics: As a second-level discipline under the first-level discipline of physics, condensed matter has many branches, and I am afraid that it will be endless for a while. However, from the rough classification of physics, it is divided into two categories: condensed matter theory and condensed matter experiment.

Condensed matter experiments are very interesting directions. If condensed matter theory is biased towards the principles and essence of physics, condensed matter experiments are more focused on verifying theories and deriving applications. There are many directions for condensed matter experiments, and I don't dare to draw conclusions about the direction of my own research that is not my own, so I will talk about the direction I have done myself.

To quote my supervisor's definition of the direction of the laboratory: the exploration of novel optoelectronic phenomena in low-dimensional physical systems has led to the discovery of new functional materials and structures with practical application value in the study of physical properties.

Low-dimensional physics: refers to macroscopic matter relative to everyday life (such as diamond, graphite, or some semiconductors that we see in our daily life). These macroscopic substances are all three-dimensional, that is, the length, width and height are not negligible in three-dimensional space.

However, when the size of a certain dimension of the source is negligible relative to other directions, the original three-dimensional material will become reduced by one dimension, which is called two-dimensional (2D material). If there is another dimension where the size is almost negligible, it becomes 1D material, which is the low-dimensional chain of things that we want to study.

In condensed matter physics, we have found that for many three-dimensional substances (such as ordinary graphite), their physical properties in low dimensions are almost completely different from those in three dimensions, which is why we study these low-dimensional physics.

Condensed matter refers to a large number of particles combined, and the particles also have a strong relationship with each other, and finally constitute a complete system, which was first proposed by Yakov Frenkel in 1947, condensed matter physics is specialized in the study of this aspect, researchers in this field want to use the laws of physics to better explain many characteristics and connections of condensed matter matter, let's take a look with this site.

The so-called condensed matter refers to the combination of a large number of particles, and the particles are also strongly related to each other, and finally form a complete system. Condensed matter is relatively common in nature, while solid and liquid states are considered condensed states, and even superfluidic states and superconducting states under low temperature conditions are also condensed states.

Research direction of condensed matter physics

Condensed matter physics is specialized in this aspect, and researchers in this field want to use the laws of physics to better explain many characteristics and relationships of condensed matter matter. Some of the laws of quantum mechanics, electromagnetism, and statistical mechanics are considered to be more important.

Both solid and liquid states are common condensed states, and as mentioned above, superconducting phases and crystals at low temperatures are also considered a type of condensed matter.

Condensed matter matter is relatively common, so research in this area is also quite active. In the United States, there are many researchers in this field, and they occupy a large part of physics. This field has a certain intersection with many fields such as chemistry and materials science, and it is also closely related to atomic physics.

Much of this research can also be used in particle physics.

The term condensed matter actually appeared very early, when it was mentioned in a professional book written by Yakov Frenkel in 1947, so it was not a new field.

Crystallography, metallurgy, and so on were initially due to the rise of relatively independent disciplines, and later in the forties of the twentieth century, physicists uniformly called Sanpeibi solid-state physics. Later, after the sixties of the twentieth century, people began to study liquid physics, and condensed matter physics began to be proposed.

Condensed matter is not a new word in physics, in fact, it has been studied for a long time, of course, the research is not perfect, and there is still a lot of knowledge waiting to be discovered.
