Strong Dipole-Dipole Interactions via Enhanced Light-Matter Coupling in Composite Nanofiber Waveguides
Kritika Jain, Lewis Ruks, Fam le Kien +1
We study the interaction of emitters with a composite waveguide formed from two parallel optical nanofibers in currently unexplored regimes of experimental importance for atomic ga…
Understanding and Improving Critical Metrology. Quenching Superradiant Light-Matter Systems Beyond the Critical Point
Karol Gietka, Lewis Ruks, Thomas Busch
We carefully examine critical metrology and present an improved critical quantum metrology protocol which relies on quenching a system exhibiting a superradiant quantum phase trans…
Green's functions of and emission into discrete anisotropic and hyperbolic baths
Lewis Ruks, Thomas Busch
In this work, we study wave propagation in generic Hermitian local periodic baths, and investigate the effects of anisotropy and quasi-breaking of periodicity on resonant emission…
Spatial distributions of the fields in guided normal modes of two coupled parallel optical nanofibers
Fam Le Kien, Lewis Ruks, Sile Nic Chormaic +1
We study the cross-sectional profiles and spatial distributions of the fields in guided normal modes of two coupled parallel optical nanofibers. We show that the distributions of t…
Coupling between guided modes of two parallel nanofibers
Fam Le Kien, Lewis Ruks, Sile Nic Chormaic +1
We study the coupling between the fundamental guided modes of two identical parallel nanofibers analytically and numerically. We calculate the coefficients of directional coupling,…
Fast control of interactions in an ultracold two atom system: Managing correlations and irreversibility
Thomás Fogarty, Lewis Ruks, Jing Li +1
We design and explore a shortcut to adiabaticity (STA) for changing the interaction strength between two ultracold, harmonically trapped bosons. Starting from initially uncorrelate…
