Simulation of time crystal behavior for a few boson chiral soliton model in a ring

Patrik Öhberg, Ewan M Wright

We present numerical simulations for a chiral soliton model with N=2,3 bosons in a ring, this being a few-particle version of our previous mean-field model for a quantum time cryst…

Interacting Bosons on Crystalline and Quasiperiodic Ladders in a Magnetic Field

Dean Johnstone, Patrik Öhberg, Callum W. Duncan

We study a variety of Hofstadter ladders in order to probe the interplay between interactions, an applied magnetic field and crystalline or quasiperiodic geometries. Rotational mot…

Staggered Ground States in an Optical Lattice

Dean Johnstone, Niclas Westerberg, Callum W. Duncan +1

Non-standard Bose-Hubbard models can exhibit rich ground state phase diagrams, even when considering the one-dimensional limit. Using a self-consistent Gutzwiller diagonalisation a…

On quantum time crystals and interacting gauge theories in atomic Bose-Einstein condensates

Patrik Öhberg, Ewan M. Wright

We study the dynamics of a Bose-Einstein condensate trapped circumferentially on a ring, and which is governed by an interacting gauge theory. We show that the associated density-d…

Vacuum radiation and frequency-mixing in linear light-matter systems

Niclas Westerberg, Angus Prain, Daniele Faccio +1

Recent progress in photonics has led to a renewed interest in time-varying media that change on timescales comparable to the optical wave oscillation time. However, these studies t…

Linked and knotted synthetic magnetic fields

Callum W Duncan, Calum Ross, Niclas Westerberg +3

We show that the realisation of synthetic magnetic fields via light-matter coupling in the Lambda-scheme implements a natural geometrical construction of magnetic fields, namely as…
