Exceptional points of arbitrary high orders induced by non-Markovian dynamics
Timofey T. Sergeev, Evgeny S. Andrianov, Alexander A. Zyablovsky
Exceptional points are singularities in the spectrum of non-Hermitian systems in which several eigenvectors are linearly dependent and their eigenvalues are equal to each other. Us…
Non-Markovian protection of states from decay in quasi-PT-symmetric systems
T. T. Sergeev, E. S. Andrianov, A. A. Zyablovsky
We consider a quasi-PT-symmetric system of two resonators, one of which interacts with a finite-size environment. The interaction with the environment leads to energy losses in the…
Transition from non-ergodic to ergodic dynamics in an autonomous discrete time crystal
T. T. Sergeev, A. A. Zyablovsky, E. S. Andrianov
We consider an autonomous system of two coupled single-mode cavities, one of which interacts with a multimode resonator. We demonstrate that for small coupling strengths between si…
