A general no-go theorem for loss-free optical torque, and its enantiomer-differential escape route
Juanjuan Ren, Reuven Gordon, Stephen Hughes
We show that an isotropic, lossless dipolar particle, locally embedded in a homogeneous, lossless host, cannot experience axial optical torque under any illumination, in any photon…
Correlation functions for quantum dynamics of coupled quasinormal modes and quantum emitters interacting via finite-delay propagating photons
Robert Meiners Fuchs, Juanjuan Ren, Sebastian Franke +2
A time-dependent theory for the interactions between spatially separated lossy cavities in a homogeneous background medium using quantized quasinormal modes (QNMs) is presented. Th…
Green's function expansion for multiple coupled optical resonators with finite retardation using quasinormal modes
Robert Meiners Fuchs, Juanjuan Ren, Stephen Hughes +1
The electromagnetic Green's function is a crucial ingredient for the theoretical study of modern photonic quantum devices, but is often difficult or even impossible to calculate di…
Dissipation in the Broadband and Ultrastrong Coupling Regimes of Cavity Quantum Electrodynamics: An Ab Initio Quantized Quasinormal Mode Approach
Chris Gustin, Juanjuan Ren, Sebastian Franke +1
Phenomenological approaches to photon loss have long been the workhorse of cavity-QED, but prove inadequate in the presence of sufficiently broadband light-matter interactions. We…
Gain-modified emission dynamics between two quantum emitters in a plasmonic gain cavity system
Becca VanDrunen, Juanjuan Ren, Sebastian Franke +1
We present a general theory of gain-modified emission dynamics between two quantum emitters (two level systems) in a linear gain medium, demonstrating how gain modifies the usual r…
What is the spectral density of the reservoir for a lossy quantized cavity?
Chris Gustin, Juanjuan Ren, Stephen Hughes
By considering a two-level system weakly coupled to a single lossy three-dimensional cavity mode, and using a quasinormal mode expansion for the photonic medium, we show that the f…
