Can angular oscillations probe superfluidity in dipolar supersolids?
arXiv:2111.07768
Toggle Abstract
Angular oscillations can provide a useful probe of the superfluid properties of a system. Such
measurements have recently been applied to dipolar supersolids, which exhibit both density modulation and phase coherence, and for which robust probes of superfluidity are particularly interesting.
So far, these investigations have been confined to linear droplet arrays. Here, we explore angular
oscillations in systems with 2D structure, which in principle have greater sensitivity to superfluidity.
Surprisingly, in both experiment and simulation, we find that the frequency of angular oscillations
remains nearly unchanged even when the superfluidity of the system is altered dramatically. This
indicates that angular oscillation measurements do not always provide a robust experimental probe
of superfluidity with typical experimental protocols.

In this review, we present the ongoing developments in bridging the gap between holography and experiments. To this end, we discuss information scrambling and models of quantum teleportation via Gao-Jafferis-Wall wormhole teleportation. We review the essential basics and summarize some of the recent works that have so far been obtained in quantum simulators towards a goal of realizing analogous models of holography in a lab.
