Universal scaling of many-body effects in quantum tunneling
Hongmian Shui, Chi-Kin Lai, Chengyang Wu +6
Quantum tunneling is fundamental to diverse phenomena and underpins a wide range of modern technologies. In the study of superconducting quantum computation and high-temperature su…
Enhancement of superconducting stiffness in hybrid superconducting-metallic bilayers
J. E. Ebot, Lorenzo Pizzino, Sam Mardazad +3
Boosting superconductivity by metallic reservoirs is the essence of Kivelson's bilayer proposal. One layer provides pairing to the electrons, while the weakly coupled metal provide…
Mapping reservoir-enhanced superconductivity to near-long-range magnetic order in the undoped one-dimensional Anderson and Kondo lattices
J. E. Ebot, Lorenzo Pizzino, Sam Mardazad +3
The undoped Kondo necklace in 1D is a paradigmatic and well understood model of a Kondo insulator. This work performs the first large-scale study of the 1D Anderson-lattice underly…
Leggett's bound and superfluidity in strongly interacting bosons
Lorenzo Pizzino, Haocong Pan, Thierry Giamarchi +1
A density-based superfluid bound called Leggett's bound has been proved to be a good estimator of the superfluid fraction for cold atomic gases in the mean-field regime. Here, we i…
Strong enhancements to superconducting properties of 1D systems from metallic reservoirs
J. E. Ebot, Sam Mardazad, Lorenzo Pizzino +3
Using a 1D bilayer system comprised of pairing and metallic layers, the present work proves the striking power of reservoir-mediated boosting of superconductivity. Employing many-b…
Probing universal phase diagram of dimensional crossover with an atomic quantum simulator
Jinyuan Tian, Zhongcheng Yu, Jing Liu +7
Dimensionality is a fundamental concept in physics, which plays a hidden but crucial role in various domains, including condensed matter physics, relativity and string theory, stat…
Finite size analysis for interacting bosons at the 2D-1D Dimensional Crossover
Lorenzo Pizzino, Hepeng Yao, Thierry Giamarchi
In this work, we extend the analysis of interacting bosons at 2D-1D dimensional crossover for finite size and temperature by using field-theory approach (bosonization) and quantum…
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…
Solving 2D and 3D lattice models of correlated fermions -- combining matrix product states with mean field theory
Gunnar Bollmark, Thomas Köhler, Lorenzo Pizzino +6
Correlated electron states are at the root of many important phenomena including unconventional superconductivity (USC), where electron-pairing arises from repulsive interactions.…
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…
