Title: Enhancement of long-wave vibronic interaction and quantum diffusion in liquids
Authors: Vladimir Hizhnyakov and Aleksander Shelkan
Abstract summary: The zero-phonon type hoping motion of defects in the solid and liquid phases, causing quantum diffusion, is considered. 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.

Abstract: The zero-phonon type hoping motion of defects in the solid and liquid phases, causing quantum diffusion, is considered. 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 compared to the solid phase of the same substance at a close temperature. Quantum diffusion may be particularly important in superfluid 4He. This is especially true for vacancies that can move here in the form of vacancy waves (zero vacancies).

Coherent expansion of the motional state of a massive nanoparticle beyond its linear dimensions [0.0]
Quantum mechanics predicts that massive particles exhibit wave-like behavior. We experimentally achieve an unprecedented degree of position diffusion in a massive levitated optomechanical system.

Superfluidity and sound propagation in disordered Bose gases [0.0]
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.

The strongly driven Fermi polaron [49.81410781350196]
Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. 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.

Fragmented superconductivity in the Hubbard model as solitons in Ginzburg-Landau theory [58.720142291102135]
Superconductivity and charge density waves are observed in close vicinity in strongly correlated materials. We investigate the nature of such an intertwined state of matter stabilized in the phase diagram of the elementary $t$-$tprime$-$U$ Hubbard model. We provide conclusive evidence that the macroscopic wave functions of the superconducting fragments are well-described by soliton solutions of a Ginzburg-Landau equation.

Dissipative stabilization of maximal entanglement between non-identical emitters via two-photon excitation [49.1574468325115]
Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Multi-band Bose-Einstein condensate at four-particle scattering resonance [47.187609203210705]
We show that magnon quantization for thin samples results in a new multi-band magnon condensate. The most stable multi-band condensate is found in a narrow regime favoured on account of a resonance in the scattering between two bands.

Crystallization of Bosonic Quantum Hall States [0.0]
We study the purely interaction-driven dynamics of a Landau gauge Bose-Einstein condensate in and near the lowest Landau level (LLL) We observe a spontaneous crystallization driven by condensation of magneto-rotons, excitations visible as density modulations at the magnetic length.

Interferences between Bogoliubov excitations and their impact on the evidence of superfluidity in a paraxial fluid of light [0.8336477625900557]
Paraxial fluids of light are an alternative platform to atomic Bose-Einstein condensates and superfluid liquids. We show that interferences between the phonon excitations that would be a clear signature of the collective superfluid behaviour have not been observed to date. Results are evidence of a key signature of light superfluidity and provide a novel characterization tool for quantum simulations with photons.

Zitterbewegung and Klein-tunneling phenomena for transient quantum waves [77.34726150561087]
We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
