Temperature dependence of $p$ -wave contacts in a harmonically trapped Fermi gas

Kenta Nagase, Hikaru Takahashi, Soki Oshima +1

We study the dependence of the $p$ -wave contact on the Fermi temperature $T_{F}$ and reduced temperature $T / T_{F}$ based on the number of closed-channel molecules. From the anisotropic…

Spin-Depairing-Induced Exceptional Fermionic Superfluidity

Soma Takemori, Kazuki Yamamoto, Akihisa Koga

We investigate the non-Hermitian (NH) attractive Hubbard model with spin depairing, which is a spin-resolved asymmetric hopping that nonreciprocally operates spins in the opposite…

Semisuper Efimov effect induced by resonant pair exchange in mixed dimensions

Yusuke Nishida

We introduce a new member to the class of semisuper Efimov effects, where an infinite number of bound states emerge with their binding energies obeying the universal scaling law $E…

Measurement-induced phase transitions for free fermions in a quasiperiodic potential

Toranosuke Matsubara, Kazuki Yamamoto, Akihisa Koga

We study the dynamics under continuous measurements for free fermions in a quasiperiodic potential by using the Aubry-André-Harper model with hopping rate $J$ and potential strengt…

Observation of slow relaxation due to Hilbert space fragmentation in strongly interacting Bose-Hubbard chains

Kantaro Honda, Yosuke Takasu, Shimpei Goto +4

While isolated quantum systems generally thermalize after long-time evolution, there are several exceptions defying thermalization. A notable mechanism of such nonergodicity is the…

Measurement of $p$ -wave contacts in an ultracold Fermi gas of $^{6}$ Li atoms

Kenta Nagase, Soki Oshima, Hikaru Takahashi +1

Using radio-frequency (RF) spectroscopy, we measure the $p$ -wave contacts in a Fermi gas of $^{6}$ Li atoms near the $p$ -wave Feshbach resonance. The RF spectrum exhibits clear asympt…

An Equation of State for Turbulence in the Gross-Pitaevskii model

Gevorg Martirosyan, Kazuya Fujimoto, Nir Navon

We report the numerical observation of a far-from-equilibrium equation of state (EOS) in the Gross-Pitaevskii model. We first show that the momentum distribution of the turbulent c…

Hydrodynamic Attractor in Ultracold Atoms

Keisuke Fujii, Tilman Enss

The hydrodynamic attractor is a concept that describes universal equilibration behavior in which systems lose microscopic details before hydrodynamics becomes applicable. We propos…

Exploring the Strongly-Interacting Regime of Effective Multi-Body Interactions in a Trapped Ultracold Atom System

Kantaro Honda, Yosuke Takasu, Yuki Haruna +2

A two-body interaction or force between quantum particles is ubiquitous in nature, and the microscopic description in terms of the bare two-body interaction is the basis for quanti…

Observation of pattern stabilization in a driven superfluid

Nikolas Liebster, Marius Sparn, Elinor Kath +6

The formation of patterns in driven systems has been studied extensively, and their emergence can be connected to a fine balance of instabilities and stabilization mechanisms. Whil…
