Observing the emergence of a velocity hierarchy in matter waves
Xudong Yu, Wenhan Chen, Igor Zhuravlev +8
Classical waves in dispersive media naturally exhibit distinct phase and group velocities. Whether an analogous separation of velocities can emerge in matter waves under strong man…
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…
The wave nature of a Mott insulator
Xudong Yu, Chengyang Wu, Wenhan Chen +10
Quantum phases of matter are routinely identified by coherence features, with interference patterns being one of the most directly observable quantities. In lattices, the superflui…
Energy-resolved transport of ultracold atoms across the Anderson transition: theory and experiment
Jean-Philippe Banon, Sacha Barré, Ke Xie +7
In a recent experiment [X. Yu et al., arXiv:2602.07654], energy-resolved measurements of an atomic matter wave spreading in a speckle potential enabled the direct observation of th…
Direct Observation of the Three-Dimensional Anderson Transition with Ultracold Atoms in a Disordered Potential
Xudong Yu, Ke Xie, Hoa Mai Quach +7
Anderson localization of particles -- the complete halt of wave transport through multiple scattering and phase coherence -- is a paradigmatic manifestation of quantum interference…
