Exotic critical states as fractional Fermi seas in the one-dimensional Bose gas
Alvise Bastianello, Yi Zeng, Sudipta Dhar +7
Critical quantum field theories occupy a central position in modern theoretical physics for their inherent universality stemming from long-range correlations. As an example, the To…
Realization of fractional Fermi seas
Yi Zeng, Alvise Bastianello, Sudipta Dhar +7
The Pauli exclusion principle is a cornerstone of quantum physics: it governs the structure of matter. Extensions of this principle, such as Haldane's generalized exclusion statist…
Generalized Hydrodynamics of Bloch Oscillations in the Absence of a Lattice
Stefano Scopa, Philip Zechmann, Michael Knap +2
Objects subjected to a constant force generally increase their velocity over time. This expectation fails whenever their energy is a smooth and periodic function of momentum, resul…
Anomalous hydrodynamic fluctuations in the quantum XXZ spin chain
Takato Yoshimura, Žiga Krajnik, Alvise Bastianello +1
The quantum XXZ spin-1/2 chain features non-Gaussian spin current fluctuations in the regime of easy-axis anisotropy. Using ballistic macroscopic fluctuation theory, we derive the…
Experimental observation of ballistic correlations in integrable turbulence
Elias Charnay, Adrien Escoubet, Francois Copie +4
Unequal-time correlation functions fundamentally characterize emergent statistical properties in complex systems, yet their direct measurement in experiments is challenging. We rep…
Observation of a generalized Gibbs ensemble in photonics
Alvise Bastianello, Alexey Tikan, Francois Copie +2
In generic classical and quantum many-body systems, where typically energy and particle number are the only conserved quantities, stationary states are described by thermal equilib…
