Nodal structure of bound-state wave functions for systems with quartic dispersion
E. V. Gorbar, B. E. Grinyuk, V. P. Gusynin
The nodal structure of bound-state wave functions for one-dimensional quantum systems with quartic energy-momentum dispersion and polynomial potentials is analysed by using the sem…

Bound states of quasiparticles with quartic dispersion in an external potential: WKB approach
E. V. Gorbar, V. P. Gusynin
The Wentzel-Kramers-Brillouin semiclassical method is formulated for quasiparticles with quartic-in-momentum dispersion which presents the simplest case of a soft energy-momentum d…

Viscoelastic tensor and hydrodynamics of altermagnets
A. A. Herasymchuk, E. V. Gorbar, P. O. Sukhachov
We calculate the viscoelasticity tensor for altermagnets and formulate the corresponding hydrodynamic equations. The anisotropy of altermagnetic Fermi surfaces allows for additiona…
