Ab initio theory of the non-resonant Raman effect in crystals at finite temperature in comparison to experiment: The examples of GaN and BaZrS3
Florian Knoop, Nimrod Benshalom, Matan Menahem +4
We present an ab initio theory of the non-resonant Raman scattering process in crystals at finite temperature in direct comparison with experiments. The theory incorporates the sca…
Effective Hamiltonians in the Quantum Rabi Problem
P. Gartner, V. Moldoveanu
We revisit the theoretical description of the ultrastrong light-matter interaction in terms of exactly solvable effective Hamiltonians. A perturbative approach based on polaronic a…
Quantum dot exciton dephasing by Coulomb interaction. A fermionic analogue of the independent boson model
I. V. Dinu, M. Tolea, P. Gartner
The time evolution of a quantum dot exciton in Coulomb interaction with wetting layer carriers is treated using an approach similar to the independent boson model. The role of the…
Spontaneous symmetry breaking in the laser transition
P. Gartner
In analogy with equilibrium phase transitions, we address the problem of the instability to symmetry-breaking perturbations of systems undergoing a laser transition. The symmetry i…
Delayed transition to coherent emission in nanolasers with extended gain media
Frederik Lohof, Roy Barzel, Paul Gartner +1
The realization of high- lasers is one of the prime applications of cavity-QED promising ultra-low thresholds, integrability and reduced power consumption in the field of \texti…
Strong light-matter coupling in the presence of lasing
Christopher Gies, Fabian Gericke, Paul Gartner +10
The regime of strong light-matter coupling is typically associated with weak excitation. With current realizations of cavity-QED systems, strong coupling may persevere even at elev…
