Photon blockade with ground-state neutral atoms
A. Cidrim, T. S. do Espirito Santo, J. Schachenmayer +2
We show that induced dipole-dipole interactions allow for photon blockade in subwavelength ensembles of two-level, ground-state neutral atoms. Our protocol relies on the energy shi…
Collective Dissipative Molecule Formation in a Cavity
David Wellnitz, Stefan Schütz, Shannon Whitlock +2
We propose a mechanism to realize high-yield molecular formation from ultracold atoms. Atom pairs are continuously excited by a laser, and a collective decay into the molecular gro…
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…
Supersolid stripe crystal from finite-range interactions on a lattice
Guido Masella, Adriano Angelone, Fabio Mezzacapo +2
Strong, long-range interactions present a unique challenge for the theoretical investigation of quantum many-body lattice models, due to the generation of large numbers of competin…
Doublon dynamics of Bose-Fermi mixtures in optical lattices
Martin Gärttner, Arghavan Safavi-Naini, Johannes Schachenmayer +1
We study the out-of-equilibrium dynamics of a dilute, lattice-confined Bose-Fermi mixture initialized in a highly excited state consisting of boson-fermion pairs (doublons) occupyi…

Quasicrystals remain among the most intriguing materials in physics and chemistry. Their structure results in many unusual properties including anomalously low friction as well as…
A generalized phase space approach for solving quantum spin dynamics
Bihui Zhu, Ana Maria Rey, Johannes Schachenmayer
Numerical techniques to efficiently model out-of-equilibrium dynamics in interacting quantum many-body systems are key for advancing our capability to harness and understand comple…
Signatures of Self-Organised Criticality in an Ultracold Atomic Gas
S. Helmrich, A. Arias, G. Lochead +3
Self organisation provides an elegant explanation for how complex structures emerge and persist throughout nature. Surprisingly often, these structures exhibit remarkably similar s…
Exploring out-of-equilibrium quantum magnetism and thermalization in a spin-3 many-body dipolar lattice system
S. Lepoutre, J. Schachenmayer, L. Gabardos +7
Understanding quantum thermalization through entanglement build-up in isolated quantum systems addresses fundamental questions on how unitary dynamics connects to statistical physi…

Nóra Sándor, Rosario González-Férez, Paul S. Julienne +1
We propose a novel scheme to efficiently tune the scattering length of two colliding ground-state atoms by off-resonantly coupling the scattering-state to an excited Rydberg-molecu…
Time-domain Ramsey interferometry with interacting Rydberg atoms
Christian Sommer, Guido Pupillo, Nobuyuki Takei +4
We theoretically investigate the dynamics of a gas of strongly interacting Rydberg atoms subject to a time-domain Ramsey interferometry protocol. The many-body dynamics is governed…
PT invariant Weyl semimetals in gauge symmetric systems
L. Lepori, I. C. Fulga, A. Trombettoni +1
Weyl semimetals typically appear in systems in which either time-reversal (T) or inversion (P}) symmetry are broken. Here we show that in the presence of gauge potentials these top…

We investigate the quantum phases of hard-core bosonic atoms in an extended Hubbard model where particles interact via soft-shoulder potentials in one dimension. Using a combinatio…
Tuneable defect interactions and supersolidity in dipolar quantum gases on a lattice potential
Wolfgang Lechner, Fabio Cinti, Guido Pupillo
Point defects in self-assembled crystals, such as vacancies and interstitials, attract each other and form stable clusters. This leads to a phase separation between perfect crystal…
