Toward the establishment of non-equilibrium (quasi-equilibrium) magnon BEC theory
In 2006, Demokritov et al have reported that they have achieved the observation of quasi-equilibrium magnon Bose-Einstein condensation (BEC) in YIG at finite (room) temperature by using the method ...

How would a diffraction pattern change if the atoms were triangular instead of spheres?
On a related note, what's a good book/source that would answer questions that go very in depth with these kinds of "what if" questions because I am also asked the same if the atoms were long cylinders ...

What limits the maximum attainable Fermi Energy for a material experimentally?
Either through doping or gating. What are some good terms to search for if I'm looking for some experimentally obtained values for particular materials? I'm particularly interested in what the limit ...

limits of diamond anvils for high pressure research
in this wikipedia article regarding diamond anvils, it mentions that the pressure peaks roughly at 300 GPa.
My question is why is this so? is the diamond crystal structure collapsing if higher ...

Numerical value of surface dipole moment/charge of a solid
Due to the open boundary, electric potential near the surface are distorted and hence there exist finite dipole moment/charge distribution. (I think it is a few angstrom thick)
Can I calculate the ...

Quasi 1D insulators with strong spin-orbital interaction
We know that the spin-1 chain realizes the Haldane phase which is an example of
symmetry protected topological (SPT) phases (ie short-range entangled phases with symmetry). The Haldane phase is ...

Is there a way to directly observe the spin texture of the surface states of topological insulators?
Is there a way to directly, here I means in real space, observe the interaction of the surface states of 3D topological insulators with defects (dopings and adatoms)? How to observe the spin texture ...

How does spring constant change with resistivity changes
I want to create a set of silicon based materials that have been doped with different materials and/or different amounts of dopants. The purpose of this is to see how the spring constant of silicon ...
