Hydrodynamic magnetoresistance in graphene Corbino devices
Alex Levchenko, Songci Li, A. V. Andreev
We study hydrodynamic electron magnetotransport in graphene devices. We show that in these systems a distinct mechanism of magnetoresistance appears, which is absent in systems wit…
Hydrodynamic electron transport in graphene Hall-bar devices
Songci Li, A. V. Andreev, Alex Levchenko
We consider hydrodynamic electron transport in the Hall-bar geometry. The theory is developed for systems with non-Galilean-invariant electron liquids. We show that inhomogeneity o…
Conformal maps of viscous electron flow in the Gurzhi crossover
Songci Li, Maxim Khodas, Alex Levchenko
We investigate the impact of geometric constriction on the viscous flow of electron liquid through quantum point contacts. We provide analysis on the electric potential distributio…
Qualifying ringdown and shadow of black holes under general parametrized metrics with photon orbits
Song Li, Ahmadjon A. Abdujabbarov, Wen-Biao Han
The motion of photons around black holes determines the shape of shadow and match the ringdown properties of a perturbed black hole. Observations of shadows and ringdown waveforms…
Magnon hybridization in ferrimagnetic heterostructures
Song Li, Ka Shen, Ke Xia
We study magnon hybridization in a ferrimagnetic heterostructure consisting of ultrathin gadolinium iron garnet and yttrium iron garnet layers and show the localized and extended s…
Fluctuational Anomalous Hall and Nernst Effects in Superconductors
Songci Li, Alex Levchenko
In this work we develop microscopic kinetic theory of the anomalous Hall and Nernst effects in superconductors induced by fluctuations in the vicinity of the critical transition te…
