Branching high-order exceptional points in non-hermitian optical systems
Konrad Tschernig, Kurt Busch, Demetrios N. Christodoulides +1
Exceptional points are complex-valued spectral singularities that lead to a host of intriguing features such as loss-induced transparency - a counterintuitive process in which an i…
Wading through the void: Exploring quantum friction and nonequilibrium fluctuations
Daniel Reiche, Francesco Intravaia, Kurt Busch
When two or more objects move relative to one another in vacuum, they experience a drag force which, at zero temperature, usually goes under the name of quantum friction. This cont…
Cavity optomechanics with ultra-cold Bose gases for quasiparticle state manipulation and prospects for sensing applications
Benjamin Maaß, Daniel Hartley, Kurt Busch +1
Ensembles of ultra-cold atoms have been proven to be versatile tools for high precision sensing applications. Here, we present a method for manipulation and readout of the state of…
Electromagnetic Viscosity in Complex Structured Environments: From black-body to Quantum Friction
M. Oelschläger, D. Reiche, C. H. Egerland +2
We investigate the nonconservative open-system dynamics of an atom in a generic complex structured electromagnetic environment at temperature . In such systems, when the atom mo…
Entangled Two-Photon Absorption Spectroscopy with Varying Pump Wavelength
Lutz Mertenskötter, Kurt Busch, Roberto de J. León-Montiel
In virtual-state spectroscopy, information about the energy-level structure of an arbitrary sample is retrieved by Fourier transforming sets of measured two-photon absorption proba…
