Altermagnetism across the BCS-BEC crossover
Iogann Tolbatov, Luca Salasnich
We study a two-dimensional paired Fermi system in which altermagnetism produces a spin splitting that depends on momentum. The interaction strength is described through the two-bod…
Electrostatic lens of a charged vortex
Iogann Tolbatov, Luca Salasnich
We study the local electrostatic response of a charged superfluid in the presence of a cylindrically symmetric vortex, allowing both the particle density and the thermodynamic comp…
Superdiffusive two-dimensional superconductors
Iogann Tolbatov, Luca Salasnich
We formulate a non-local, field-theoretic description of phase fluctuations and topological transitions in two-dimensional (2D) superconductors by generalizing the local only-phase…
A study of stability of the "plasma - beam" system for the Lorentz plasma
Iogann Tolbatov
The stability of the system comprising the cold immobile Lorentz plasma of density and the directed nonrelativistic (velocity ) electronic beam of a small density $N…
Superconducting nanodrop model
Iogann Tolbatov
Superconducting nanodrop model is constructed on the basis of the assumption of equality of the free energy functional gradient term to zero due to the order parameter value consta…
To the identification of universal criterion of the charged particles system stability
Iogann Tolbatov
We consider the problem important for the condensed matter physics, superconductivity physics, and electrodynamics of continuous media - the problem of the matter dielectric permit…
