Scaling theory of decoherence in Dicke superradiance
Nico S. Bassler, Julian Lyne, Javier Cuerda
The survival of many-body coherence depends on the competition between correlation buildup and decoherence. In Dicke superradiance, collective emission builds up correlations, prod…
Dicke superradiance in degenerate quantum matter: interplay of exchange statistics and spatial confinement
Julian Lyne, Kai Phillip Schmidt, Claudiu Genes +1
Collective radiance effects in quantum degenerate systems, such as superradiance and subradiance of a partially inverted ensemble, are shaped by the interplay of spatial confinemen…
Symbolic Quantum-Trajectory Method for Multichannel Dicke Superradiance
Raphael Holzinger, Nico S. Bassler, Julian Lyne +2
We solve Dicke superradiance with two or more competing collective decay channels of tunable rates using a symbolic quantum-trajectory construction. The method yields closed time-d…
Absence of Entanglement Growth in Dicke Superradiance
Nico S. Bassler
Dicke superradiance describes an ensemble of permutationally invariant two-level systems collectively emitting radiation with a peak radiated intensity scaling as . Althou…
Solving Dicke superradiance analytically: A compendium of methods
Raphael Holzinger, Nico S. Bassler, Julian Lyne +3
We present several analytical approaches to the Dicke superradiance problem, which involves determining the time evolution of the density operator for an initially inverted ensembl…
Generalized energy gap law: An open system dynamics approach to non-adiabatic phenomena in molecules
N. S. Bassler, M. Reitz, R. Holzinger +4
Non-adiabatic molecular phenomena, arising from the breakdown of the Born-Oppenheimer approximation, govern the fate of virtually all photo-physical and photochemical processes and…
Purcell modified Doppler cooling of quantum emitters inside optical cavities
Julian Lyne, Nico S. Bassler, Seong eun Park +2
Standard cavity cooling of atoms or dielectric particles is based on the action of dispersive optical forces in high-finesse cavities. We investigate here a complementary regime ch…
Cooperative effects in dense cold atomic gases including magnetic dipole interactions
N. S. Bassler, I. Varma, M. Proske +3
We theoretically investigate cooperative effects in cold atomic gases exhibiting both electric and magnetic dipole-dipole interactions, such as occurring for example in clouds of d…
Metasurface-based hybrid optical cavities for chiral sensing
Nico S. Bassler, Andrea Aiello, Kai P. Schmidt +2
Quantum metasurfaces, i.e., two-dimensional subwavelength arrays of quantum emitters, can be employed as mirrors towards the design of hybrid cavities, where the optical response i…
Scaling law for Kasha's rule in photoexcited molecular aggregates
Raphael Holzinger, Nico S. Bassler, Helmut Ritsch +1
We study the photophysics of molecular aggregates from a quantum optics perspective, with emphasis on deriving scaling laws for the fast non-radiative relaxation of collective elec…
Linear optical elements based on cooperative subwavelength emitter arrays
Nico S. Bassler, Michael Reitz, Kai P. Schmidt +1
We describe applications of two-dimensional subwavelength quantum emitter arrays as efficient optical elements in the linear regime. For normally incident light, the cooperative op…
Effects of domain walls in bilayer graphene in an external magnetic field
N. S. Bassler, K. P. Schmidt
We investigate bilayer graphene systems with layer switching domain walls separating the two energetically equivalent Bernal stackings in the presence of an external magnetic field…
