Emergent spatial structure and entanglement localization in Floquet conformal field theory

R Fan, Y Gu, A Vishwanath, X Wen - Physical Review X, 2020 - APS
We study the energy and entanglement dynamics of (1+ 1) D conformal field theories (CFTs)
under a Floquet drive with the sine-square deformed (SSD) Hamiltonian. Previous work has …

Many-body dynamics with time-dependent interaction

Y Cheng, ZY Shi - Physical Review A, 2021 - APS
In this work we study the many-body dynamics of Bose-Einstein condensates subject to an
arbitrary time-varying scattering length. By employing a variational ansatz which assumes …

Maximum energy growth rate in dilute quantum gases

R Qi, Z Shi, H Zhai - Physical Review Letters, 2021 - APS
In this Letter we study how fast the energy density of a quantum gas can increase in time,
when the interatomic interaction characterized by the s-wave scattering length as is …

Quantum dynamics of cold atomic gas with SU (1, 1) symmetry

J Zhang, X Yang, C Lv, S Ma, R Zhang - Physical Review A, 2022 - APS
Motivated by recent advances in quantum dynamics, we investigate the dynamics of the
system with SU (1, 1) symmetry. Instead of performing the time-ordered integral for the …

Periodically and quasi-periodically driven dynamics of Bose-Einstein condensates

P Zhang, Y Gu - SciPost Physics, 2020 - scipost.org
We study the quantum dynamics of Bose-Einstein condensates when the scattering length is
modulated periodically or quasi-periodically in time within the Bogoliubov framework. For …

Observation of dynamical super-efimovian expansion in a unitary fermi gas

S Deng, P Diao, F Li, Q Yu, S Yu, H Wu - Physical review letters, 2018 - APS
We report an observation of a dynamical super Efimovian expansion in a strongly interacting
Fermi gas by engineering time dependent external harmonic trap frequencies. When the …

Efimov effect in Dirac semi-metals

P Zhang, H Zhai - Frontiers of Physics, 2018 - Springer
The Efimov effect is defined as a quantum state with discrete scaling symmetry and a
universal scaling factor. It has attracted considerable interests from nuclear to atomic physics …

Super Efimovian expansions of superfluid Fermi gases in the BCS–BEC crossover

L Zhang, W Wen, XD Ma, Y Wang - International Journal of Modern …, 2018 - World Scientific
We study the super Efimovian expansions of a superfluid Fermi gas in the crossover from
Bardeen–Cooper–Schrieffer (BCS) superfluid to a Bose–Einstein condensate (BEC), by …
