Can we observe non-perturbative vacuum shifts in cavity QED?
Rocío Sáez-Blázquez, Daniele de Bernardis, Johannes Feist +1
We address the fundamental question whether or not it is possible to achieve conditions under which the coupling of a single dipole to a strongly confined electromagnetic vacuum ca…
Vacuum-field-induced state mixing
Diego Fernández de la Pradilla, Esteban Moreno, Johannes Feist
By engineering the electromagnetic vacuum field, the induced Casimir-Polder shift (also known as Lamb shift) and spontaneous emission rates of individual atomic levels can be contr…
Non-Hermitian Anharmonicity Induces Single-Photon Emission
Anael Ben-Asher, Antonio I. Fernández-Domínguez, Johannes Feist
Single-photon sources are in high demand for quantum information applications. A paradigmatic way to achieve single-photon emission is through anharmonicity in the energy levels, s…
Chiral Discrimination in Helicity-Preserving Fabry-Pérot Cavities
L. Mauro, J. Fregoni, J. Feist +1
We theoretically study circular dichroism of chiral molecules embedded inside a helicity-preserving Fabry-Pérot cavity. We find an increase of the intrinsic chiroptical response of…
A theoretical perspective on molecular polaritonics
Mónica Sánchez-Barquilla, Antonio I. Fernández-Domínguez, Johannes Feist +1
In the last decade, much theoretical research has focused on studying the strong coupling between organic molecules (or quantum emitters, in general) and light modes. The descripti…
Permutational symmetry for identical multi-level systems: a second quantized approach
Rui E. F. Silva, Johannes Feist
We develop a framework that provides a straightforward approach to fully exploit the permutational symmetry of identical multi-level systems. By taking into account the permutation…
