Quantum transport enabled by non-adiabatic transitions
Ajith Ramachandran, Alexander Eisfeld, Sebastian Wüster +1
Quantum transport of charge or energy in networks with discrete sites is central to diverse quantum technologies, from molecular electronics to light harvesting and quantum opto-me…
Excitons guided by polaritons
K. Mukherjee, S. Wüster
We show that an exciton on a discrete chain of sites can be guided by effective measurements induced by an ambient, non-equilibrium medium that is synchronised to the exciton trans…
Maximally entangled Rydberg-atom pairs via Landau-Zener sweeps
Dhiya Varghese, Sebastian Wüster, Weibin Li +1
We analyze the formation of maximally entangled Rydberg atom pairs subjected to Landau-Zener sweeps of the atom-light detuning. Though the populations reach a steady value at longe…
Dynamics of atoms within atoms
S. Tiwari, F. Engel, M. Wagner +3
Recent experiments with Bose-Einstein condensates have entered a regime in which thousands of ground-state condensate atoms fill the Rydberg-electron orbit. After the excitation of…
Solitary waves explore the quantum-to-classical transition
A. Sreedharan, S Kuriyattil, S. Choudhury +3
It is an open fundamental question how the classical appearance of our environment arises from the underlying quantum many-body theory. We propose that phenomena involved in the qu…
Quantum dynamics of long-range interacting systems using the positive-P and gauge-P representations
S. Wüster, J. F. Corney, J. M. Rost +1
We provide the necessary framework for carrying out stochastic positive-P and gauge-P simulations of bosonic systems with long range interactions. In these approaches, the quantum…
Quantum Zeno suppression of dipole-dipole forces
Sebastian Wüster
We consider inter-atomic forces due to resonant dipole-dipole interactions within a dimer of highly excited Rydberg atoms, embedded in an ultra-cold gas. These forces rely on a coh…
Non-Hermitian matter wave mixing in Bose Einstein condensates: dissipation induced amplification
S. Wüster, R. El-Ganainy
We investigate the nonlinear scattering dynamics in interacting atomic Bose-Einstein condensates under non-Hermitian dissipative conditions. We show that by carefully engineering a…
Coupling of a nano mechanical oscillator and an atomic three-level medium
A. Sanz-Mora, A. Eisfeld, S. Wüster +1
We theoretically investigate the coupling of an ultracold three-level atomic gas and a nano-mechanical mirror via classical electromagnetic radiation. The radiation pressure on the…
