Two-mode collapse and revival of quantum coherent state in a tilted optical lattice
Chi-Kin Lai, Shengjie Jin, Yuanzhe Hu +6
Collective dynamics is an important out-of-equilibrium feature of quantum coherent states and usually reflects the intrinsic properties of the state. Collapse and revival (CR) dyna…
Quench spectroscopy for Lieb-Liniger bosons in the presence of harmonic trap
Jiachen Yu, Yuanzhe Hu, Wenhan Chen +3
Quench spectroscopy has emerged as a novel and powerful technique for probing the energy spectrum of various quantum phases for quantum systems from out-of-equilibrium dynamics. Wh…
Direct measurement of Tan's contact in a one-dimensional Lieb-Liniger gas
Qi Huang, Hepeng Yao, Xuzong Chen +1
The Tan contact has emerged as a pivotal quantity in characterizing many-body quantum systems, bridging microscopic short-range correlations to thermodynamic behavior. It is define…
Weak Superfluidity in Twisted Optical Potentials
Dean Johnstone, Shanya Mishra, Zhaoxuan Zhu +2
A controlled twist between different underlying lattices allows one to interpolate, under a unified framework, across ordered and (quasi-)disordered matter while drastically changi…
Mott transition for a Lieb-Liniger gas in a shallow quasiperiodic potential: Delocalization induced by disorder
Hepeng Yao, Luca Tanzi, Laurent Sanchez-Palencia +3
Disorder or quasi-disorder is known to favor the localization in many-body Bose systems. Here in contrast, we demonstrate an anomalous delocalization effect induced by incommensura…
Cooling bosons by dimensional reduction
Yanliang Guo, Hepeng Yao, Sudipta Dhar +5
Cold atomic gases provide a remarkable testbed to study the physics of interacting many-body quantum systems. They have started to play a major role as quantum simulators, given th…
Experimental Observation of the 2D-1D Dimensional Crossover in Strongly Interacting Ultracold Bosons
Yanliang Guo, Hepeng Yao, Satwik Ramanjanappa +6
Dimensionality plays an essential role in determining the nature and properties of a physical system. For quantum systems the impact of interactions and fluctuations is enhanced in…
Thermodynamic Phase Diagram of Two-Dimensional Bosons in a Quasicrystal Potential
Zhaoxuan Zhu, Hepeng Yao, Laurent Sanchez-Palencia
Quantum simulation of quasicrystals in synthetic bosonic matter now paves the way to the exploration of these intriguing systems in wide parameter ranges. Yet thermal fluctuations…
Strongly-interacting bosons at 2D-1D Dimensional Crossover
Hepeng Yao, Lorenzo Pizzino, Thierry Giamarchi
We study a two dimensional (2D) system of interacting quantum bosons, subjected to a continuous periodic potential in one direction. The correlation of such system exhibits a dimen…
A momentum dependent optical lattice induced by artificial gauge potential
Zekai Chen, Hepeng Yao, Elisha Haber +1
We propose an experimentally feasible method to generate a one-dimensional optical lattice potential in an ultracold Bose gas system that depends on the transverse momentum of the…
Strongly-Interacting Bosons in a Two-Dimensional Quasicrystal Lattice
Ronan Gautier, Hepeng Yao, Laurent Sanchez-Palencia
Quasicrystals exhibit exotic properties inherited from the self-similarity of their long-range ordered, yet aperiodic, structure. The recent realization of optical quasicrystal lat…
One dimensional quasiperiodic mosaic lattice with exact mobility edges
Yucheng Wang, Xu Xia, Long Zhang +5
The mobility edges (MEs) in energy which separate extended and localized states are a central concept in understanding the localization physics. In one-dimensional (1D) quasiperiod…
Lieb-Liniger Bosons in a Shallow Quasiperiodic Potential: Bose Glass Phase and Fractal Mott Lobes
Hepeng Yao, Thierry Giamarchi, Laurent Sanchez-Palencia
The emergence of a compressible insulator phase, known as the Bose glass, is characteristic of the interplay of interactions and disorder in correlated Bose fluids. While widely st…
Critical Behavior and Fractality in Shallow One-Dimensional Quasiperiodic Potentials
Hepeng Yao, Alice Khoudli, Léa Bresque +1
Quasiperiodic systems offer an appealing intermediate between long-range ordered and genuine disordered systems, with unusual critical properties. One-dimensional models that break…
Tan's Contact for Trapped Lieb-Liniger Bosons at Finite Temperature
Hepeng Yao, David Clément, Anna Minguzzi +2
The universal Tan relations connect a variety of microscopic features of many-body quantum systems with two-body contact interactions to a single quantity, called the contact. The…
