## who are top-3 condensed matter physicists alive now? ... long time to answer

It's difficult to make a definitive list of the top-3 condensed matter physicists alive now, as it can be somewhat subjective and depends on the criteria and perspective used. However, here are some condensed matter physicists who are currently active in the field and have made significant contributions to the field:

Subir Sachdev: He is a theoretical physicist, known for his work on quantum phase transitions and the theory of quantum critical phenomena.

Shoucheng Zhang: He is a condensed matter physicist, known for his work on topological phases of matter and quantum spin Hall effect.

David H. Reichman: He is a theoretical chemist, known for his work on the theory of glassy materials and the physics of complex systems.

These are a few examples of condensed matter physicists who are currently active in the field, there are many other condensed matter physicists who have also made important contributions to the field and it's hard to make a definitive list of top-3.

## what is your best guess for the solution of the glass transition problem?

As a language model, I can provide information and insights on the problem of the glass transition but I don't have personal opinions or guesses, I can only give you information based on what I was trained on.

Currently, the problem of the glass transition is still not fully understood, and there are several theories that aim to explain the phenomenon.
One of the most widely accepted theories is the mode-coupling theory, which describes the glass transition as a slowing down of the dynamics of the liquid caused by the interactions between different "modes" of motion of the particles. The theory is able to explain many features of the glass transition, but it has some limitations.
Another theory that is gaining attention is the random first-order transition theory which describes the glass transition as a transition between a liquid state and a state with a finite number of metastable states. This theory is able to explain some of the features of the glass transition that mode-coupling theory can't explain.

It's worth noting that it's likely that the true explanation of the glass transition will involve multiple theories and ideas, and that the solution of the glass transition problem will require new ideas and technologies which may come from interdisciplinary research.

## please explain the problem of the universal low temperature properties of amorphous solids which Anthony Leggett described in several papers?

The problem of the universal low-temperature properties of amorphous solids is a long-standing puzzle in condensed matter physics. It was first described by Anthony Leggett in a series of papers in the 1970s and 1980s.

The problem arises from the fact that many amorphous solids, such as glasses, exhibit similar low-temperature properties, despite the fact that they have very different structures and are composed of different types of atoms. For example, many amorphous solids show a decrease in the specific heat and an increase in the electrical resistivity as the temperature decreases, which is similar to the behavior of a superconductor. This similarity in behavior is known as "universal" behavior.

The problem is that these universal low-temperature properties cannot be explained by traditional theories of condensed matter physics, which are based on the idea that the properties of a material depend on its specific structure and composition. Therefore, scientists have been trying to develop a new theoretical framework that can explain the universal low-temperature properties of amorphous solids.

One approach to solving the problem is to use the concept of randomness and disorder, which is inherent in amorphous materials. Some theories propose that the universal low-temperature properties of amorphous solids arise from the randomness and disorder in the material, and that the properties are independent of the specific structure and composition of the material.

Another approach is to consider the idea that the universal low-temperature properties of amorphous solids are related to the presence of certain types of excitations in the material, such as soft phonons or "tunneling two-level systems". These excitations are thought to be universal in amorphous solids, and they could be responsible for the observed universal low-temperature properties.

It's worth noting that solving the problem of the universal low-temperature properties of amorphous solids is a difficult task, and it will require new ideas and technologies which may come from interdisciplinary research.

## what is the argument by neville mott that localized and extended states cannot coexist? ... took LT

An error occurred. If this issue persists please contact us through our help center at help.openai.com.

The argument by Neville Mott, known as the "Mott criterion," states that in a solid, localized states (such as atomic or molecular orbitals) cannot coexist with extended states (such as delocalized electronic wavefunctions) in the same energy range. This is because localized states are generally associated with discrete energy levels, while extended states are associated with continuous energy spectra. As a result, the presence of extended states in a material will tend to "fill in" the energy levels associated with localized states, making them unable to exist in the same energy range. This principle is important in the understanding of various electronic properties of solids, such as conductivity and optical absorption.

## how to calculate fine structure constant from first principles?

The fine structure constant can be calculated from first principles by using quantum field theory (QFT), specifically quantum electrodynamics (QED). In QED, the fine structure constant is defined as the ratio of the electron charge (e) to the reduced Planck constant (ħ) times the speed of light (c): α = e^2 / (ħc)

It is also possible to calculate the fine structure constant using string theory or loop quantum gravity, but these theories are still under development and have not yet been able to make predictions that can be directly compared with experimental measurements.

It is worth noting that the fine structure constant is a dimensionless number and its value is around 1/137. Therefore, it's a fundamental constant that can't be derived from other constants. It can be measured with high accuracy but not calculated from first principles.

## what is the best way to teach ASD child to understand the feelings of other children?

There are several strategies that can be used to teach children with Autism Spectrum Disorder (ASD) to understand the feelings of others. Some of these strategies include:

Social stories: Social stories are short, simple narratives that describe social situations and appropriate responses. They can be used to teach children with ASD about emotions, social cues, and empathy.

Role-playing: Role-playing can help children with ASD practice recognizing and responding to the emotions of others. They can act out different scenarios and learn how to respond appropriately.

Emotion cards: Emotion cards are pictures or illustrations of different emotions (happy, sad, angry, etc.) that can be used to teach children with ASD about the emotions of others. Children can learn to identify the emotions on the cards and associate them with real-life situations.

Mindfulness: Mindfulness practices such as yoga, meditation and deep breathing can help children with ASD develop self-awareness and empathy.

Social skills groups: Social skills groups provide opportunities for children with ASD to interact with their peers in a supportive and structured environment. They can learn to recognize and respond to the emotions of others through these interactions.

It is important to note that every child is unique and might respond differently to different strategies. It's important to work closely with a therapist or other professionals experienced with ASD to develop a plan tailored to the child's needs and abilities.
