Spin waves in a superconductor
Serguei N. Burmistrov
Spin waves that can propagate in normal and superconducting metals are investigated. Unlike normal metals, the velocity of spin waves becomes temperature-dependent in a superconduc…

Ginzburg-Landau approximation for the Hubbard model in the external magnetic field
L. B. Dubovskii, S. N. Burmistrov
The Hubbard model is studied in the external magnetic field. The analysis is carried out phenomenologically within the framework of the Ginzburg-Landau theory with the order parame…

Charge-induced instability and macroscopic quantum nucleation phenomena at the crystal 4He facet
S. N. Burmistrov
An existence of the charge-induced instability is well known for the 4He crystal surface in the rough state. Much less is known about charge-induced instability at the 4He crystal…
