Topological phases of lattice bosons with a dynamical gauge field
David Raventós, Tobias Graß, Bruno Juliá-Díaz +2
Optical lattices with a complex-valued tunnelling term have become a standard way of studying gauge-field physics with cold atoms. If the complex phase of the tunnelling is made de…
Dual trapped-ion quantum simulators: an alternative route towards exotic quantum magnets
Tobias Graß, Maciej Lewenstein, Alejandro Bermudez
We present a route towards the quantum simulation of exotic quantum magnetism in ion traps by exploiting dual relations between different spin models. Our strategy allows one to st…
Quantum Simulation of a Topological Mott Insulator with Rydberg Atoms in a Lieb Lattice
A. Dauphin, M. Müller, M. A. Martin-Delgado
We propose a realistic scheme to quantum simulate the so-far experimentally unobserved topological Mott insulator phase -- an interaction-driven topological insulator -- using cold…
Competing valence bond and symmetry breaking Mott states of spin-3/2 fermions on a honeycomb lattice
D. Jakab, E. Szirmai, M. Lewenstein +1
We investigate magnetic properties of strongly interacting four component spin-3/2 ultracold fermionic atoms in the Mott insulator limit with one particle per site in an optical la…
One-dimensional Bose gas in optical lattices of arbitrary strength
Grigory E. Astrakharchik, Konstantin V. Krutitsky, Maciej Lewenstein +1
One-dimensional Bose gas with contact interaction in optical lattices at zero temperature is investigated by means of the exact diffusion Monte Carlo algorithm. The results obtaine…
Hidden string order in a hole-superconductor with extended correlated hopping
Ravindra W. Chhajlany, Przemysław R. Grzybowski, Julia Stasińska +2
Ultracold fermions in a one-dimensional, spin-dependent, optical lattice are described by a non-standard Hubbard model with next-nearest-neighbour correlated hopping. Periodic driv…
Many interacting fermions in a one-dimensional harmonic trap: a quantum-chemical treatment
Tomasz Grining, Michał Tomza, Michał Lesiuk +5
We employ \textit{ab initio} methods of quantum chemistry to investigate spin-1/2 fermions interacting via a two-body contact potential in a one-dimensional harmonic trap. The conv…
Quantum annealing for the number partitioning problem using a tunable spin glass of ions
Tobias Graß, David Raventós, Bruno Juliá-Díaz +2
Exploiting quantum properties to outperform classical ways of information-processing is an outstanding goal of modern physics. A promising route is quantum simulation, which aims a…
Crossover between few and many fermions in a harmonic trap
Tomasz Grining, Michał Tomza, Michał Lesiuk +5
The properties of a balanced two-component Fermi gas in a one-dimensional harmonic trap are studied by means of the coupled cluster method. For few fermions we recover the results…
Magnetism in strongly interacting one-dimensional quantum mixtures
Pietro Massignan, Jesper Levinsen, Meera M. Parish
We consider two species of bosons in one dimension near the Tonks-Girardeau limit of infinite interactions. For the case of equal masses and equal intraspecies interactions, the sy…
Quantum simulation of conductivity plateaux and fractional quantum Hall effect using ultracold atoms
Nuria Barberán, Daniel Dagnino, Miguel Angel García-March +3
We analyze the role of impurities in the fractional quantum Hall effect using a highly controllable system of ultracold atoms. We investigate the mechanism responsible for the form…
Spontaneous PT symmetry breaking of a ferromagnetic superfluid in a gradient field
Thomas Vanderbruggen, Silvana Palacios, Simon Coop +2
We consider the interaction of a ferromagnetic spinor Bose-Einstein condensate with a magnetic field gradient. The magnetic field gradient realizes a spin-position coupling that ex…
