Enhancing nanomechanical squeezing by atomic interactions in a hybrid atom-optomechanical system
Niklas Mann, Michael Thorwart
In a hybrid atom-optomechanical system, the optical coupling of a mechanical mode of a nanomembrane in an optical cavity with a distant interacting atom gas permits highly non-clas…
Tuning the Order of the Nonequilibrium Quantum Phase Transition in a Hybrid Atom-Optomechanical System
Niklas Mann, Axel Pelster, Michael Thorwart
We show that a hybrid atom-optomechanical quantum many-body system with two internal atom states undergoes both first- and second-order nonequilibrium quantum phase transitions. A…
Nonequilibrium Quantum Phase Transition in a Hybrid Atom-Optomechanical System
Niklas Mann, M. Reza Bakhtiari, Axel Pelster +1
We consider a hybrid quantum many-body system formed by both a vibrational mode of a nanomembrane, which interacts optomechanically with light in a cavity, and an ultracold atom ga…
Driven Bose-Hubbard Model with a Parametrically Modulated Harmonic Trap
N. Mann, M. Reza Bakhtiari, F. Massel +2
We investigate a one-dimensional Bose-Hubbard model in a parametrically driven global harmonic trap. The delicate interplay of both the local atom interaction and the global drivin…
Dissipative dynamics of a quantum two-state system in presence of nonequilibrium quantum noise
Niklas Mann, Jochen Brüggemann, Michael Thorwart
We analyze the real-time dynamics of a quantum two-state system in the presence of nonequilibrium quantum fluctuations. The latter are generated by a coupling of the two-state syst…
Probing chirality fluctuations in molecules by nonlinear optical spectroscopy
N. Mann, P. Nalbach, S. Mukamel +1
Symmetry breaking caused by geometric fluctuations can enable processes that are otherwise forbidden. An example is a perylene bisimide dyad whose dipole moments are perpendicular…
Relativistic Linear Restoring Force
D. Clark, J. Franklin, N. Mann
We consider two different forms for a relativistic version of a linear restoring force. The pair comes from taking Hooke's law to be the force appearing on the right of the relativ…
