Deep learning based quantum vortex detection in atomic Bose-Einstein condensates

1 code implementation24 Dec 2020 Friederike Metz, Juan Polo, Natalya Weber, Thomas Busch

Quantum vortices naturally emerge in rotating Bose-Einstein condensates (BECs) and, similarly to their classical counterparts, allow the study of a range of interesting out-of-equilibrium phenomena like turbulence and chaos.

Spatial distributions of the fields in guided normal modes of two coupled parallel optical nanofibers

no code implementations11 Dec 2020 Fam Le Kien, Lewis Ruks, Sile Nic Chormaic, Thomas Busch

We show that the distributions of the components of the field in a guided normal mode of two identical nanofibers are either symmetric or antisymmetric with respect to the radial principal axis and the tangential principal axis in the cross-sectional plane of the fibers.

Universal and optimal coin sequences for high entanglement generation in 1D discrete time quantum walks

no code implementations16 Mar 2020 Aikaterini Gratsea, Friederike Metz, Thomas Busch

First, we present and analyze a deterministic sequence of coin operators which produces high values of entanglement in a universal manner for a class of localized initial states.

Spontaneous Emission in ultra-cold spin-polarised anisotropic Fermi Seas

1 code implementation1 Oct 2008 Brian O'Sullivan, Thomas Busch

We examine and explain the spatial emission patterns of ultracold excited fermions in anisotropic trapping potentials in the presence of a spin polarised Fermi sea of ground state atoms.
