Nonlinear Diamagnetic Interactions in Ultrastrongly Coupled 2D Electrons
Dasom Kim, Kiran M. Kulkarni, Vaibhav Sharma +15
The quantum Hopfield model is widely used to describe ultrastrong light--matter coupling between cavity photons and collective bosonic excitations in solids, where the diamagnetic…
Matrix Product State Theory of Few-Photon Squeezed Pulses Interacting with a Two-Level Emitter in a Waveguide
Sofia Arranz Regidor, Matthew Kozma, Stephen Hughes
Squeezed light states have a special place in quantum optics with potentially profound applications in emerging quantum technologies. We present a numerically-exact matrix product…
Probing the nonlocality of Landau levels in GaAs quantum wells through modified Purcell factors, Lamb shifts and dipole emitted spectra
Lara Greten, Sabrina Meyer, Christina Schröder +2
In a two-dimensional electron gas, a strong perpendicular magnetic field confines electrons to quantized cyclotron orbits, giving rise to Landau levels with discrete orbit radii. E…
Pulsed two-photon scattering from a single atom in a waveguide with delay-modified temporal correlations
Matthew Kozma, Sofia Arranz Regidor, Stephen Hughes
Quantum nonlinearity is an essential ingredient for many quantum technologies, but often the nonlinearity is too weak to be exploited at the few-photon level. However, few photons…
QwaveMPS: An efficient open-source Python package for simulating non-Markovian waveguide-QED using matrix product states
Sofia Arranz Regidor, Matthew Kozma, Stephen Hughes
QwaveMPS is an open-source Python library for simulating one-dimensional quantum many-body waveguide systems using matrix product states (MPS). It provides a user-friendly interfac…
