Macroscopic self-trapping in the dynamical tunneling of a Bose-Einstein condensate
Sebastian Wüster, Joy Cree, Matthew J. Davis
A Bose-Einstein condensate in a modulated, one-dimensional, anharmonic potential can exhibit dynamical tunneling between islands of regular motion in phase space. With increasingly…
The disordered Dicke model
Pragna Das, Sebastian Wüster, Auditya Sharma
We introduce and study the disordered Dicke model in which the spin-boson couplings are drawn from a random distribution with some finite width. Regarding the quantum phase transit…
Trapping and binding by dephasing
Kaustav Mukherjee, Siddhartha Poddar, Sebastian Wüster
The binding and trapping of particles usually rely on conservative forces, described by unitary quantum dynamics. We show that both can also arise solely from spatially dependent d…
Transmission in a Fano-Anderson chain with a topological defect
Ritu Nehra, Ajith Ramachandran, Sebastian Wüster +1
The Fano-Anderson chain consists of a linear lattice with a discrete side-unit, and exhibits Fano-resonant scattering due to coupling between the discrete states of the side-unit w…
A measure for adiabatic contributions to quantum transitions
R. Pant, P. K. Verma, C. Rangi +4
We construct a measure for the adiabatic contribution to quantum transitions in an arbitrary basis, tackling the generic complex case where dynamics is only partially adiabatic, si…
Multi-Excitons in Flexible Rydberg Aggregates
Ghassan Abumwis, Sebastian Wüster
Flexible Rydberg aggregates, assemblies of few Rydberg atoms coherently sharing electronic excitations while undergoing directed atomic motion, show great promise as quantum simula…
