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…
Counterdiabatic Optimised Local Driving
Ieva Čepaitė, Anatoli Polkovnikov, Andrew J. Daley +1
Adiabatic protocols are employed across a variety of quantum technologies, from implementing state preparation and individual operations that are building blocks of larger devices,…
Barriers to Macroscopic Superfluidity and Insulation in a 2D Aubry-André Model
Dean Johnstone, Patrik Öhberg, Callum W. Duncan
We study the ground state phases of interacting bosons in the presence of a 2D Aubry-André potential. By using a a mean-field percolation analysis, we focus on several superlattice…
