Cavity induced many-body localization
Rong-Chun Ge, Saeed Rahmanian Koshkaki, Michael H. Kolodrubetz
In this manuscript, we explore the feasibility of achieving many-body localization in the context of cavity quantum electrodynamics at strong coupling. Working with a spinless elec…
Floquet engineering of lattice structure and dimensionality in twisted moiré heterobilayers
Rong-Chun Ge, Michael Kolodrubetz
We present an experimental proposal to tune the effective lattice structure in twisted transition metal dichalcogenide (TMD) heterobilayers with time-periodic Floquet drive. We sho…
Quasiperiodic Floquet-Thouless energy pump
Frederik Nathan, Rongchun Ge, Snir Gazit +2
Recent work [M. H. Kolodrubetz et al, PRL 120, 150601] has demonstrated that periodically driven one-dimensional fermionic systems can support quantized energy pumping resulting fr…
Floquet engineering flat bands for bosonic fractional quantum Hall in small lattices
Rongchun Ge, Michael Kolodrubetz
The quest to realize novel phases of matter with topological order is an important pursuit with implications for strongly correlated physics and quantum information. Utilizing idea…
Anti-chiral edge states in an exciton polariton strip
S. Mandal, R. Ge, T. C. H. Liew
We present a scheme to obtain anti-chiral edge states in an exciton-polariton honeycomb lattice with strip geometry, where the modes corresponding to both edges propagate in the sa…
Exciton-polariton topological insulator
S. Klembt, T. H. Harder, O. A. Egorov +9
Topological insulators (TIs) are a striking example of materials in which topological invariants are manifested in robustness against perturbations. Their most prominent feature is…
Floquet Topological Polaritons in Semiconductor Microcavities
Rongchun Ge, Wijnand Broer, Timothy C. H. Liew
We propose and model Floquet topological polaritons in semiconductor microcavities, using the interference of frequency detuned coherent fields to provide a time periodic potential…
Reply to "Comment on "Normalization of quasinormal modes in leaky optical cavities and plasmonic resonators" " by E. A. Muljarov and W. Langbein
Philip Trøst Kristensen, Rong-Chun Ge, Stephen Hughes
We refute all claims of the "Comment on "Normalization of quasinormal modes in leaky optical cavities and plasmonic resonators" " by E. A. Muljarov and W. Langbein (arXiv:1602.0727…
Quasinormal mode theory and modelling of electron energy loss spectroscopy for plasmonic nanostructures
Rong-Chun Ge, Stephen Hughes
Understanding light-matter interactions using localized surface plasmons (LSPs) is of fundamental interest in classical and quantum plasmonics and has a wide range of applications.…
Quantum dynamics of two quantum dots coupled through localized plasmons: An intuitive and accurate quantum optics approach using quasinormal modes
Rong-Chun Ge, Stephen Hughes
We study the quantum dynamics of two quantum dots (QDs) or artificial atoms coupled through the fundamental localized plasmon of a gold nanorod resonator. We derive an intuitive an…
Design of an efficient single photon source from a metallic nanorod dimer: a quasinormal mode finite-difference time-domain approach
Rong-Chun Ge, S. Hughes
We describe how the finite-difference time-domain (FDTD) technique can be used to compute the quasinormal mode (QNM) for metallic nano-resonators, which is important for describing…
Accessing quantum nanoplasmonics in a hybrid quantum-dot metal nanosystem: Mollow triplet of a quantum dot near a metal nanoparticle
Rong-Chun Ge, C. Van Vlack, P. Yao +2
We present a theoretical study of the resonance fluorescence spectra of an optically driven quantum dot placed near a single metal nanoparticle. The metallic reservoir coupling is…
Mollow "quintuplets" from coherently-excited quantum dots
Rong-Chun Ge, S. Weiler, A. Ulhaq +4
Charge-neutral excitons in semiconductor quantum dots have a small finite energy separation caused by the anisotropic exchange splitting. Coherent excitation of neutral excitons wi…
