Quantum tribology: acceleration-induced Stokes friction and Magnus force in correlated Bose fluids
V. M. Kovalev, A. N. Osipov, I. G. Savenko
The Landau criterion, a cornerstone of quantum fluid dynamics, dictates that dissipation is forbidden for uniform motion below a critical velocity. Yet, the fundamental question of…
Anomalous acoustoelectric signatures of chiral superconductivity
A. N. Osipov, V. N. Ivanova, V. M. Kovalev +1
The identification of unconventional pairing in two-dimensional materials is a central challenge in modern condensed matter physics. While chiral p-wave superconductivity offers a…
Giant resonant nonlinear THz valley Hall effect in 2D Dirac semiconductors
V. N. Ivanova, V. M. Kovalev, I. G. Savenko
We predict a giant cyclotron resonance in the nonlinear valley Hall response of inversion-asymmetric two-dimensional semiconductors subjected to crossed terahertz electric and stat…
Synchronization-induced flat bands in driven-dissipative dimer-waveguide chains
A. N. Osipov, I. G. Savenko, Sergej Flach +1
Flat bands in driven-dissipative systems offer a route to engineer strongly localized, long-lived excitations, yet their selective population via incoherent pumping remains an open…
Ratchet Hall Effect in Fluctuating Superconductors
A. V. Parafilo, V. M. Kovalev, I. G. Savenko
We propose a superconducting ratchet-induced Hall effect (RHE), characterized by the emergence of a unidirectional, rectified flux of fluctuating Cooper pairs in a two-dimensional…
Vertex corrections to nonlinear photoinduced currents in 2D superconductors
A. V. Parafilo, V. M. Kovalev, I. G. Savenko
The emergence of a rectified steady-state supercurrent as a response to the photoexcited current of the quasiparticles constitutes the concept of a superconducting photodiode. This…
