Enhancement of second-harmonic generation in micropillar resonator due to the engineered destructive interference
Stanislav Kolodny, Valerii Kozin, Ivan Iorsh
We show, that engineering the cavity aspect ratio of AlGaAs micropillar resonator allows for the two order of magnitude increase in the efficiency of second harmonic generation at…
Chiral waveguide optomechanics: first order quantum phase transitions with symmetry breaking/
Denis Sedov, Valerii Kozin, Ivan Iorsh
We present a direct mapping between the quantum optomechanical problem of the atoms harmonically trapped in the vicinity of a chiral waveguide and a generalized quantum Rabi model…
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…
A connection between -invariants and Yang-Baxter -operators in super-Yang-Mills theory
V. K. Kozin
The BCFW recursion relation in super-Yang-Mills theory is solved using Yang-Baxter -operators in the NMHV sector. Explicit expressions for -invarian…
