Quantum dynamics of non-Hermitian many-body Landau-Zener systems
Rajesh K. Malla, Julia Cen, Wilton J. M. Kort-Kamp +1
We develop a framework to solve a large class of linearly driven non-Hermitian quantum systems. Such a class of models in the Hermitian scenario is commonly known as multi-state La…
Spectral Filtering Induced by Non-Hermitian Evolution with Balanced Gain and Loss: Enhancing Quantum Chaos
Julien Cornelius, Zhenyu Xu, Avadh Saxena +2
The dynamical signatures of quantum chaos in an isolated system are captured by the spectral form factor, which exhibits as a function of time a dip, a ramp, and a plateau, with th…
Wormhole as a Waveguide: Case of Quantum Particles with Zero Angular Momentum
Victor Atanasov, Rossen Dandoloff, Avadh Saxena
We consider a static wormhole as a waveguide and determine the conditions for full transmission through the wormhole waveguide for a quantum particle with zero angular momentum. We…
Parity-time symmetric systems with memory
Zachary A. Cochran, Avadh Saxena, Yogesh N. Joglekar
Classical open systems with balanced gain and loss, i.e. parity-time () symmetric systems, have attracted tremendous attention over the past decade. Their exotic prop…
Anti--symmetric Qubit: Decoherence and Entanglement Entropy
Julia Cen, Avadh Saxena
We investigate a two-level spin system based anti-parity-time (anti-)-symmetric qubit and study its decoherence as well as entanglement entropy properties. We compare…
Quantum Electron Transport in Degenerate Donor-Acceptor Systems
Marco Merkli, Gennady P. Berman, Avadh Saxena
We develop a mathematically rigorous theory for the quantum transfer processes in degenerate donor-acceptor dimers in contact with a thermal environment. We calculate explicitly th…
