From coupled Rabi models to the Potts model
Anatoliy I. Lotkov, Valerii K. Kozin, Denis V. Kurlov +2
We study -symmetric Rabi model that describes a three-level system coupled to two bosonic modes. We derive a mapping of the two-mode Rabi model onto a…
Cat states in one- and two-mode Rabi models
Anatoliy I. Lotkov, Denis V. Kurlov, Valerii K. Kozin +2
We investigate one- and two-mode variants of the -symmetric quantum Rabi model, which describe the interaction of a qutrit with one or two bosonic modes and are direc…
QDistRnd: A GAP package for computing the distance of quantum error-correcting codes
Leonid P. Pryadko, Vadim A. Shabashov, Valerii K. Kozin
The GAP package QDistRnd implements a probabilistic algorithm for finding the minimum distance of a quantum low-density parity-check code linear over a finite field GF(q). At each…
Reply to "Comment on "Quantum Time Crystals from Hamiltonians with Long-Range Interactions""
Valerii K. Kozin, Oleksandr Kyriienko
In the note by Khemani et al. [arXiv:2001.11037] the authors express conceptual disagreement with our recent paper on quantum time crystals [Phys. Rev. Lett. 123, 210602]. They cri…
Quantum Time Crystals from Hamiltonians with Long-Range Interactions
Valerii K. Kozin, Oleksandr Kyriienko
Time crystals correspond to a phase of matter where time-translational symmetry (TTS) is broken. Up to date, they are well studied in open quantum systems, where external drive all…
