Well done. You've clicked the tower. This would actually achieve something if you had logged in first. Use the key for that. The name takes you home. This is where all the applicables sit. And you can't apply any changes to my site unless you are logged in.

Our policy is best summarized as "we don't care about _you_, we care about _them_", no emails, so no forgetting your password. You have no rights. It's like you don't even exist. If you publish material, I reserve the right to remove it, or use it myself.

Don't impersonate. Don't name someone involuntarily. You can lose everything if you cross the line, and no, I won't cancel your automatic payments first, so you'll have to do it the hard way. See how serious this sounds? That's how serious you're meant to take these.

Ferromagnetic and metamagnetic transitions in itinerant electron systems: a microscopic study. (arXiv:2111.10068v2 [cond-mat.str-el] UPDATED)

Click here to flash read.

We perform a microscopic study of itinerant ferromagnetic systems. We reveal
a very rich phase diagram in the three-dimensional space spanned by the
chemical potential, a magnetic field, and temperature beyond the Landau theory
analyzed so far. Besides a generic wing structure near a tricritical point upon
introducing the magnetic field, we find that an additional wing can be
generated close to a quantum critical end point (QCEP) and also even from
deeply inside the ferromagnetic phase. A tilting of the wing controls the
entropy jump associated with the metamagnetic transition. Ferromagnetic and
metamagnetic transitions are usually accompanied by a Lifshitz transition at
low temperatures, i.e., a change of Fermi surface topology including the
disappearance of the Fermi surface. In particular, the Fermi surface of either
spin band vanishes at the QCEP. These rich phase diagrams are understood in
terms of the density of states and the breaking of particle-hole symmetry in
the presence of a next nearest-neighbor-hopping integral t', which is expected
in actual materials. The obtained phase diagrams are discussed in a possible
connection to itinerant ferromagnetic systems such as UGe2, UCoAl, ZrZn2, and
others including materials exhibiting the magnetocaloric effect.
