Stochastic discrete time crystals: Entropy production and subharmonic synchronization
Lukas Oberreiter, Udo Seifert, Andre C. Barato
Discrete time crystals are periodically driven systems that display spontaneous symmetry breaking of time translation invariance in the form of indefinite subharmonic oscillations.…

Subharmonic oscillations in stochastic systems under periodic driving
Lukas Oberreiter, Udo Seifert, Andre C. Barato
Subharmonic response is a well known phenomena in, e.g., deterministic nonlinear dynamical systems. We investigate the conditions under which such subharmonic oscillations can pers…

Population transfer at exceptional points in spectra of the hydrogen atom in parallel electric and magnetic fields
Lukas Oberreiter, Jan Burkhardt, Jörg Main +1
We study the population transfer between resonance states for a time-dependent loop around exceptional points in spectra of the hydrogen atom in parallel electric and magnetic fiel…
