Controlling dephasing of coupled qubits via shared-bath coherence
L. M. J. Hall, L. S. Sirkina, A. Morreau +2
The interaction of a quantum system with its environment limits its coherence time. This, in particular, restricts the utility of qubits in quantum information processing applicati…
Exceptional points in perturbed dielectric spheres: A resonant-state expansion study
Kyle S. Netherwood, Hannah K. Riley, Egor A. Muljarov
Exceptional points (EPs) in open optical systems are rigorously studied using the resonant-state expansion (RSE). A spherical resonator, specifically a homogeneous dielectric spher…
Impact of the phonon environment on the nonlinear quantum-dot-cavity QED. I. Path-integral approach
L. S. Sirkina, E. A. Muljarov
We demonstrate a strong influence of the phonon environment on the coherent dynamics of the quantum dot (QD)-cavity system in the quantum strong coupling regime. This regime is imp…
Impact of the phonon environment on the nonlinear quantum-dot cavity QED. II. Analytical approach
L. S. Sirkina, E. A. Muljarov
The effect of phonons on a nonlinear optical response of a quantum dot-cavity system in quantum strong coupling regime can be accounted for by a fully analytical treatment, provide…
Transverse-electric surface plasmon polaritons in periodically modulated graphene
Zeeshan Ahmad, Sang Soon Oh, Egor A. Muljarov
Transverse-electric (TE) surface plasmon polaritons are unique eigenmodes of a homogeneous graphene layer that are tunable with the chemical potential and temperature. However, as…
First-order perturbation theory of eigenmodes for systems with interfaces
Zoltan Sztranyovszky, Wolfgang Langbein, Egor A. Muljarov
We present an exact first-order perturbation theory for the eigenmodes in systems with interfaces causing material discontinuities. We show that when interfaces deform, higher-orde…
