Boosting thermalization of classical and quantum many-body systems
Jin-Fu Chen, Kshiti Sneh Rai, Patrick Emonts +5
Understanding and optimizing the relaxation dynamics of many-body systems is essential both for foundational studies in quantum thermodynamics and for applications such as quantum…
Universal representation by Boltzmann machines with Regularised Axons
Przemysław R. Grzybowski, Antoni Jankiewicz, Eloy Piñol +7
It is widely known that Boltzmann machines are capable of representing arbitrary probability distributions over the values of their visible neurons, given enough hidden ones. Howev…
Population annealing with topological defect driven nonlocal updates for spin systems with quenched disorder
David Cirauqui, Miguel Ángel García-March, José Ramón Martínez Saavedra +2
Population Annealing, one of the currently state-of-the-art algorithms for solving spin-glass systems, sometimes finds hard disorder instances for which its equilibration quality a…
Quantum Random Number Generators : Benchmarking and Challenges
David Cirauqui, Miguel Ángel García-March, Guillem Guigó Corominas +5
We discuss the current state of the art of Quantum Random Number Generators (QRNG) and their possible applications in the search for quantum advantages. To this aim, we first discu…
Haake-Lewenstein-Wilkens approach to spin-glasses revisited
Maciej Lewenstein, David Cirauqui, Miguel Angel Garcia-March +5
We revisit the Haake-Lewenstein-Wilkens (HLW) approach to Edwards-Anderson (EA) model of Ising spin glass [Phys. Rev. Lett. 55, 2606 (1985)]. This approach consists in evaluation a…
Cold atoms meet lattice gauge theory
Monika Aidelsburger, Luca Barbiero, Alejandro Bermudez +19
The central idea of this review is to consider quantum field theory models relevant for particle physics and replace the fermionic matter in these models by a bosonic one. This is…
Dynamical solitons and boson fractionalization in cold-atom topological insulators
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +2
We study the Bose-Hubbard model at incommensurate densities, which describes a one-dimensional system of interacting bosons whose tunneling is dressed by a dynamical…
Efficient training of energy-based models via spin-glass control
Alejandro Pozas-Kerstjens, Gorka Muñoz-Gil, Eloy Piñol +4
We introduce a new family of energy-based probabilistic graphical models for efficient unsupervised learning. Its definition is motivated by the control of the spin-glass propertie…
Control of anomalous diffusion of a Bose polaron
Christos Charalambous, Miguel Ángel García-March, Gorka Muñoz-Gil +2
We study the diffusive behavior of a Bose polaron immersed in a coherently coupled two-component Bose-Einstein Condensate (BEC). Polaron superdiffuses if it couples in the same man…
Nanoscale phase separation and pseudogap in the hole-doped cuprates from fluctuating Cu-O-Cu bonds
Sergi Julià-Farré, Alexandre Dauphin, Ravindra W. Chhajlany +4
The pseudogap phenomenology is one of the enigmas of the physics of high-Tc superconductors. Many members of the cuprate family have now been characterized with high resolution in…
solitons in intertwined topological phases
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +2
Topological phases of matter can support fractionalized quasi-particles localized at topological defects. The current understanding of these exotic excitations, based on the celebr…
Intertwined Topological Phases induced by Emergent Symmetry Protection
Daniel González-Cuadra, Alejandro Bermudez, Przemysław R. Grzybowski +2
The dual role played by symmetry in many-body physics manifests itself through two fundamental mechanisms: spontaneous symmetry breaking and topological symmetry protection. These…
Symmetry-Breaking Topological Insulators in the Bose-Hubbard Model
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +3
In this work, we study a one-dimensional model of interacting bosons coupled to a dynamical field, the Bose-Hubbard model, and analyze the interplay b…
Strongly Correlated Bosons on a Dynamical Lattice
Daniel González-Cuadra, Przemysław R. Grzybowski, Alexandre Dauphin +1
We study a one-dimensional system of strongly correlated bosons on a dynamical lattice. To this end, we extend the standard Bose-Hubbard Hamiltonian to include extra degrees of fre…
Minimal energy ensemble Monte Carlo for the partition function of fermions coupled to classical fields
Przemysław R. Grzybowski, Łukasz Czekaj, Mariusz Nogala +2
Models of non-interacting fermions coupled to auxilliary classical degrees of freedom are relevant to the understanding of a wide variety of problems in many body physics, {\it e.g…
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…
Hubbard-I approach to the Mott transition
Przemyslaw R. Grzybowski, Ravindra W. Chhajlany
We expose the relevance of double occupancy conservation symmetry in application of the Hubbard-I approach to strongly correlated electron systems. We propose the utility of a comp…
