- Authors: Leo Radzihovsky, Anatoly Kuklov, Nikolay Prokof'ev, Boris Svistunov
- Abstract summary: We show that stability of supercurrents controlled by quantum phase slips (instantons) follow from a one-dimensional quantum liquid.
This establishes a new class of quasi-one-dimensional superfluid states that remain stable and long-range ordered despite their low dimensionality.

- Abstract: Recently, it has been argued by Kuklov et al., that unusual features
associated with the superflow-through-solid effect observed in solid He4 can be
explained by unique properties of dilute distribution of superfluid edge
dislocations. We demonstrate that stability of supercurrents controlled by
quantum phase slips (instantons), and other exotic infrared properties of the
superfluid dislocations readily follow from a one-dimensional quantum liquid
distinguished by an effectively infinite compressibility (in the absence of
Peierls potential) associated with the edge dislocation's ability to climb.
This establishes a new class of quasi-one-dimensional superfluid states that
remain stable and long-range ordered despite their low dimensionality. We
propose an experiment to test our mass-current--pressure characteristic
prediction.

We study the effects of speckle disorder on the propagation of sound waves in a two-dimensional Bose-Einstein condensate at zero temperature.
A key result is that disorder reduces the superfluid fraction and hence the speed of sound.
Our predictions are well within the reach of state-of-the-art cold-atom experiments.

It was found that due to the previously discovered significant enhancement of vibronic interaction with long-wave acoustic phonons, this motion in liquids can be significantly amplified.

Josephson effect [0.0]
Superfluids and superconductors could be linked to the idea of a supersolid phase, featuring a macroscopic wavefunction with spatial modulation.
Key property is the superfluid fraction, which measures the reduction in superfluid stiffness due to spatial modulation.
We employ the Josephson effect, common in superfluids and superconductors, to measure the superfluid fraction in a supersolid.

We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons.
We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates.
We show that the onset of the Zeno regime is marked by a $textitcascade of transitions$ in the system dynamics as the measurement strength is increased.
