Observation of parity-time symmetry breaking transitions in a dissipative Floquet system of ultracold atoms
Jiaming Li, Andrew K. Harter, Ji Liu +3
Open physical systems with balanced loss and gain, described by non-Hermitian parity-time () reflection symmetric Hamiltonians, exhibit a transition which could engen…

String order via Floquet interactions in atomic systems
Tony E. Lee, Yogesh N. Joglekar, Philip Richerme
We study the transverse-field Ising model with interactions that are modulated in time. In a rotating frame, the system is described by a time-independent Hamiltonian with many-bod…

Mapping between Hamiltonians with attractive and repulsive potentials on a lattice
Yogesh N. Joglekar
Through a simple and exact analytical derivation, we show that for a particle on a lattice, there is a one-to-one correspondence between the spectra in the presence of an attractiv…
