Synthetic dimensions in the strong-coupling limit: supersolids and pair-superfluids
(2016-06-29)
We study the many-body phases of bosonic atoms with N internal states confined to a 1D optical lattice under the influence of a synthetic magnetic field and strong repulsive interactions. The N internal states of the atoms ...
Resonant dynamics of strongly interacting SU(n) fermionic atoms in a synthetic flux ladder
(2022-08-26)
We theoretically study the dynamics of n-level spin-orbit coupled alkaline-earth fermionic atoms with SU(n) symmetric interactions. We consider three-dimensional lattices with tunneling along one dimen- sion, and the ...
Temperature dependence of butterfly effect in a classical many-body System
(2018-08-06)
We study the chaotic dynamics in a classical many-body system of interacting spins on the kagome lattice. We characterise many-body chaos via the butter y effect as captured by an appropriate out-of-time-ordered correlator. ...
Disentangling Pauli blocking of atomic decay from cooperative radiation and atomic motion in a 2D Fermi gas
(2021-08-05)
The observation of Pauli blocking of atomic spontaneous decay via direct measurements of the atomic population requires the use of long-lived atomic gases where quantum statistics, atom recoil and cooperative radiative ...
Radial flows and angular momentum conservation in galactic chemical evolution
(2012-07-31)
We study the effects of radial flows on Galactic chemical evolution. A simple analytic scheme is developed prescribing the coupling of infall from the intergalactic medium and radial flows within the disc based on angular ...
Dynamics and energy landscape of the jammed spin-liquid
(2018-11-20)
We study the low temperature static and dynamical properties of the classical bond-disordered antiferromagnetic Heisenberg model on the kagome lattice. This model has recently been shown to host a new type of spin liquid ...
Scattering theory for Floquet-Bloch states
(2014-10-20)
Motivated by recent experimental implementations of artificial gauge fields for gases of cold atoms, we study the scattering properties of particles that are subjected to time-periodic Hamiltonians. Making use of Floquet ...
