Equations of motion governing the dynamics of the exceptional points of parameterically dependent nonhermitian Hamiltonians
Milan Šindelka, Pavel Stránský, Pavel Cejnar
We study exceptional points (EPs) of a nonhermitian Hamiltonian whose parameters and . As the real control parameter is vari…
Relative asymptotic oscillations of the out-of-time-ordered correlator as a quantum chaos indicator
Jakub Novotný, Pavel Stránský
A detailed numerical study reveals that the asymptotic values of the standard deviation-to-mean ratio of the out-of-time-ordered correlator can be successfully used as a measure of…
Decoherence-assisted quantum driving
Pavel Cejnar, Pavel Stránský, Jan Střeleček +1
We propose a protocol for transitionless driving of a bound quantum system in its parameter space using repeated measurement-like interactions with an external spectator system. As…
Search for optimal driving in finite quantum systems with precursors of criticality
Felipe Matus, Jan Střeleček, Pavel Stránský +1
Using the adiabatic perturbation theory of driven dynamics [Phys. Rev. A 78, 052508 (2008)] we design a hierarchy of quantum state preparation protocols that systematically increas…
Stabilization of product states and excited-state quantum phase transitions in a coupled qubit-field system
Pavel Stránský, Pavel Cejnar, Radim Filip
We study a system of a single qubit (or a few qubits) interacting with a soft-mode bosonic field. Considering an extended version of the Rabi model with both parity-conserving and…
