1. Radar coin
2. Yes, Wang Qing and Anna yo just use the blockchain to cheat money. They cheat our money into the fake platform to buy the fake DFT, and then they won't give you any money.
3. DFT, digital currency is an unregulated area. Many eastern and Western countries can't protect you by law. Therefore, if there is a problem, you can't protect your rights. Whether it's a scam or not can't be answered in different time dimensions
however, one thing is for sure: if there is income, there will be risk, which is extremely high risk. Be careful with the principal.

6. Most of the physical properties can be studied
there are no other experimental, empirical or semi empirical parameters except the atoms you use and their positions in the calculation. So if the cell size is too large, the computing speed is slow and a lot of computing resources are needed
there is no problem in studying phase transition under pressure. The software you see in this edition can study phase transition
first principles first principles are usually associated with calculation, which means that there are no other experimental, empirical or semi empirical parameters except the atoms you use and their positions in the calculation, and they have good portability. As the basis of evaluating things, first principles and empirical parameters are two extremes. The first principle is the conclusion of some rigid regulations or dection, while the empirical parameters are the regular data obtained through a large number of examples. These data can come from the first principle (called theoretical statistical data) or from the experiment (called experimental statistical data)
however, for a specific problem, there is no obvious boundary between first principles and empirical parameters, which must be specially defined. If some principles or data are derived from the first principles, but some assumptions are added in the dection process (these assumptions are very convincing of course), then these principles or data are called "semi empirical"
other explanations: first principle, English first principle, is a professional term of computational physics or computational chemistry. Generalized first principle calculation refers to all calculations based on the principles of quantum mechanics
we know that matter is composed of molecules, molecules are composed of atoms, and atoms are composed of nuclei and electrons. Quantum mechanics calculation is to calculate the molecular structure and molecular energy (or ion) according to the interaction principle of atomic nucleus and electron, and then calculate various properties of matter
ab initio is the first principle calculation in a narrow sense, which means that we only use a few experimental data such as electron mass, light speed, proton and neutron mass to do quantum calculation without using empirical parameters. But this calculation is very slow, so adding some empirical parameters can greatly speed up the calculation speed, and of course, it will inevitably sacrifice the accuracy of the calculation results
then why use the word "first principles"? It is said that this comes from the religious word "first impetus". The first driving force was created by Newton, because Newton's first law states that matter can keep static or uniform linear motion without external force. If everything was supposed to be static at the beginning of the birth of the universe, but it was moving later, how did it move? Newton believed that this was e to God's push, and Newton devoted himself to theological research in his later years. Modern science believes that the universe originated from the big bang, so there is a reason for the big bang. All these unclear things come down to the problem of the "first driving force" of the universe
science doesn't believe in God, and we don't know the "first driving force" problem just because our scientific knowledge is not perfect. First, the impetus must be determined by some principle. This can be called "first principles.". In his later years, Einstein devoted himself to the study of the "grand unified field theory" and also hoped to find the "first principles" that unify all the laws of physics. Unfortunately, this was beyond the level of science at that time. There is far from an answer
the generalized first principles include ab initio ab initio calculations based on Hartree fork self consistent field calculations and density functional theory (DFT) calculations. Some people hold that ab initio refers to ab initio calculation, while first principles and so-called quantum chemistry calculation refer to density functional theory calculation. We can also calculate the excited state
and do a lot. See more, O (∩)_ ∩) O ~ laohaoren2802 (TA) band density of states optical properties (dielectric function, reflection, refractive index, etc.)
there are many more. At present, I use the CASTEP mole in MS, which mainly includes the above aspects. Delinliu can't figure out the density of States, doping, vacancy, band gap and so on of smsjshd828. It's a surface... Wenliuxu (station contact TA) generalized first principles calculation refers to the calculation only under the condition of atomic position and species information, which is independent of experimental and semi empirical parameters. In a narrow sense, it means solving Schrodinger equation and so on
the transformation of alloy should start with the calculation of energy, and then be discussed in combination with the practical problems to be solved. For example, in the calculation of phase diagram of alloy transformation, some parameters can be calculated by quantum chemistry before thermodynamic calculation. Another example is the phase problem of a new compound in an alloy, which is quite annoying. The possible energy can be calculated first, then the possible structure ring phase transformation can be calculated, and the possible chemical reaction process can be deced through comparison. Gerald 2370 can calculate many things, such as surface energy, interface energy, adsorption energy, work function, band gap, hydrogen storage, reaction path, phase transition temperature, phase transition pressure and so on, By comparing work of attention. Wally8962 for me, the most important thing is the charge distribution tc1788. May I ask wenliuxu: can I calculate the problem of new compounds at different temperatures? If there is anyone to do hydrogen storage calculation, we can cooperate
