Josephson and Spin Currents in Coupled Polariton Condensates
A. Kudlis, I. Yu. Chestnov, A. N. Osipov +2
We analyze particle and spin currents in networks of coupled spinor exciton-polariton condensates arranged as plaquettes and regular polygonal rings. In closed geometries, spin-con…
Helicity effects in the dynamically assisted Schwinger mechanism
A. I. Baksheev, V. A. Bokhan, A. Kudlis +1
We study vacuum electron-positron pair production in a spatially uniform bichromatic electric field within the quantum-kinetic framework for fermions. The external background model…
Vacuum polarization and pair production in time-dependent electric fields: A quantum-kinetic-equation approach
I. A. Aleksandrov, V. A. Bokhan, A. I. Baksheev +1
The evolution of the vacuum state in a time-dependent external electric field of arbitrary polarization is investigated within a nonperturbative framework of quantum kinetic equati…
Evolution of a twisted electron wave packet perturbed by an inhomogeneous electric field
A. Kudlis, I. A. Aleksandrov, N. N. Rosanov
Laguerre-Gaussian (LG) wave packets, known for their vortex structure and nonzero orbital angular momentum (OAM), are of great interest in various scientific fields. Here we study…
Phase transitions induced by resonant light: a phenomenological approach
A. Kudlis, L. S. Ricco, H. Sigurðsson +1
We present a phenomenological framework to describe a subclass of light-induced phase transitions (LIPTs) in condensed matter systems, specifically those mediated by the resonant g…
Kardar-Parisi-Zhang universality in optically induced lattices of exciton-polariton condensates
D. Novokreschenov, V. Neplokh, M. Misko +7
We investigate space-time coherence in one-dimensional lattices of exciton-polariton condensates formed by fully reconfigurable non-resonant optical pumping. Starting from an open-…
