Precision tests of nonlinear and stochastic modifications of quantum mechanics with a 1D quantum gas
Yi Zeng, Angelo Bassi, Grigori E. Astrakharchik +3
We propose a cold-atom platform for precision tests of nonlinear and stochastic modifications to the Schrödinger equation, utilizing strongly correlated ultracold Cs in a u…
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…
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…
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…
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…
Spectroscopy and Ground-State Transfer of Ultracold Bosonic KCs Molecules
Krzysztof P. Zamarski, Charly Beulenkamp, Yi Zeng +2
We report the creation of ultracold samples of KCs molecules in their rovibrational ground state. By investigating potentially suitable excited states using one- and…
Anyonization of bosons
Sudipta Dhar, Botao Wang, Milena Horvath +7
Anyons are low-dimensional quasiparticles that obey fractional statistics, hence interpolating between bosons and fermions. In two dimensions, they exist as elementary excitations…
