One-dimensional Kronig-Penney superlattices at the LaAlO/SrTiO interface
Megan Briggeman, Hyungwoo Lee, Jung-Woo Lee +9
The paradigm of electrons interacting with a periodic lattice potential is central to solid-state physics. Semiconductor heterostructures and ultracold neutral atomic lattices capt…
Dynamics of rotated spin states and magnetic ordering with two-component bosonic atoms in optical lattices
Araceli Venegas-Gomez, Anton S. Buyskikh, Johannes Schachenmayer +2
The microscopic control available over cold atoms in optical lattices has opened new opportunities to study the properties of quantum spin models. While a lot of attention is focus…
Second-order topological corner states with ultracold atoms carrying orbital angular momentum in optical lattices
G. Pelegrí, A. M. Marques, V. Ahufinger +2
We propose a realization of a two-dimensional higher-order topological insulator with ultracold atoms loaded into orbital angular momentum (OAM) states of an optical lattice. The s…
Collisionally inhomogeneous Bose-Einstein condensates with a linear interaction gradient
Andrea Di Carli, Grant Henderson, Stuart Flannigan +6
We study the evolution of a collisionally inhomogeneous matter wave in a spatial gradient of the interaction strength. Starting with a Bose-Einstein condensate with weak repulsive…
Enhanced Superexchange in a Tilted Mott Insulator
Ivana Dimitrova, Niklas Jepsen, Anton Buyskikh +4
In an optical lattice entropy and mass transport by first-order tunneling is much faster than spin transport via superexchange. Here we show that adding a constant force (tilt) sup…
Reservoir engineering of Cooper-pair-assisted transport with cold atoms
François Damanet, Eduardo Mascarenhas, David Pekker +1
We show how Cooper-pair-assisted transport, which describes the stimulated transport of electrons in the presence of Cooper-pairs, can be engineered and controlled with cold atoms,…
Treelike interactions and fast scrambling with cold atoms
Gregory Bentsen, Tomohiro Hashizume, Anton S. Buyskikh +4
We propose an experimentally realizable quantum spin model that exhibits fast scrambling, based on non-local interactions which couple sites whose separation is a power of 2. By co…
Excitation modes of bright matter-wave solitons
Andrea Di Carli, Craig D. Colquhoun, Grant Henderson +5
We experimentally study the excitation modes of bright matter-wave solitons in a quasi-one-dimensional geometry. The solitons are created by quenching the interactions of a Bose-Ei…
Controlling Quantum Transport via Dissipation Engineering
François Damanet, Eduardo Mascarenhas, David Pekker +1
Inspired by the microscopic control over dissipative processes in quantum optics and cold atoms, we develop an open-system framework to study dissipative control of transport in st…
Measurement and feedback for cooling heavy levitated particles in low frequency traps
L. S. Walker, G. R. M. Robb, A. J. Daley
We consider a possible route to ground state cooling of a levitated nanoparticle, magnetically trapped by a strong permanent magnet, using a combination of measurement and feedback…
Observation of Non-equilibrium Motion and Equilibration in Polariton Rings
S. Mukherjee, D. M. Myers, R. G. Lena +8
We present a study of the macroscopic dynamics of a polariton condensate formed by non-resonant optical excitation in a quasi-one-dimensional ring-shaped microcavity. The presence…
Atom-only descriptions of the driven-dissipative Dicke model
François Damanet, Andrew J. Daley, Jonathan Keeling
We investigate how to describe the dissipative spin dynamics of the driven-dissipative Dicke model, describing two-level atoms coupled to a cavity mode, after adiabatic elimina…
