Quantum Time Crystals and Interacting Chiral Gauge Theories in Atomic BECs III: Role of the Page-Wootters mechanism
Patrik Öhberg, Ewan M. Wright
We build the case that our published chiral soliton model [Phys. Rev. Lett. 124, 250402 (2019)] can lead to a genuine quantum time crystal for smaller atom numbers. To do this we c…

Quantum droplets in a beyond-mean-field density-dependent gauge theory
Matthew Edmonds, Patrik Öhberg
The beyond-mean-field corrections appropriate to a bosonic many-body system experiencing a density-dependent gauge potential are derived, and from this the dimensional hierarchy of…

A Lower-Dimensional Remnant of Flux Attachment
Gerard Valentí-Rojas, Patrik Öhberg
Flux attachment is a mechanism allowing electric charges to capture magnetic flux in two spatial dimensions. Fundamentally, this is a consequence of the Aharonov-Bohm effect or, in…
