How to fix the space group in a doped super cell in VESTA?

Hi, I am working on X2YZ type compound with space group 225. Here i am trying to dope Fe on Y site. For this first i have created primitive cell by using phonopy. By using the same primitive cell...

Is there any possibility of pressure induced phase transition from tetragonal to cubic and again cubic to tetragonal at further pressures?

Dear Research Gate, Is there any possibility for a system which is tetragonal at ambient condition and have a phase change tetragonal to cubic at high pressures, and as pressure still increases...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...

Should we reduce the standard unit of length to 0.31951540592 meter ?

The reasoning behind this question is to align the ratios of the proton potential in energy per charge to the speed of light in distance per time. As these two dimensions appear to be related,...
