Emerging 2D Gauge theories in Rydberg configurable arrays
A. Celi, B. Vermersch, O. Viyuela +3
Solving strongly coupled gauge theories in two or three spatial dimensions is of fundamental importance in several areas of physics ranging from high-energy physics to condensed ma…
Transient subdiffusion from an Ising environment
G. Muñoz-Gil, C. Charalambous, M. A. GarcÃa-March +4
We introduce a model, in which a particle performs a continuous time random walk (CTRW) coupled to an environment with Ising dynamics. The particle shows locally varying diffusivit…
Optical Abelian Lattice Gauge Theories
L. Tagliacozzo, A. Celi, A. Zamora +1
We discuss a general framework for the realization of a family of abelian lattice gauge theories, i.e., link models or gauge magnets, in optical lattices. We analyze the properties…
Noncommutative Electrodynamics
G. Berrino, S. L. Cacciatori, A. Celi +2
In this paper we define a causal Lorentz covariant noncommutative (NC) classical Electrodynamics. We obtain an explicit realization of the NC theory by solving perturbatively the S…
Nonergodic subdiffusion from transient interactions with heterogeneous partners
C. Charalambous, G. Muñoz-Gil, A. Celi +4
Spatiotemporal disorder has been recently associated to the occurrence of anomalous nonergodic diffusion of molecular components in biological systems, but the underlying microscop…
Synthesis of Majorana mass terms in low-energy quantum systems
L. Lepori, A. Celi, A. Trombettoni +1
We discuss the problem of how Majorana mass terms can be generated in low-energy systems. We show that, while these terms imply the Majorana condition, the opposite is not always t…
Efficient algorithm to compute the second Chern number in four dimensional systems
M. Mochol-Grzelak, A. Dauphin, A. Celi +1
Topological insulators are exotic material that possess conducting surface states protected by the topology of the system. They can be classified in terms of their properties under…

O. Boada, A. Celi, M. Lewenstein +1
We present a general strategy to simulate a D+1-dimensional quantum system using a D-dimensional one. We analyze in detail a feasible implementation of our scheme using optical lat…
Probing supersolidity through excitations in a spin-orbit-coupled Bose-Einstein condensate
C. S. Chisholm, S. Hirthe, V. B. Makhalov +5
Spin-orbit-coupled Bose-Einstein condensates are a flexible experimental platform to engineer synthetic quantum many-body systems. In particular, they host the so-called stripe pha…
Simulating Lattice Gauge Theories within Quantum Technologies
M. C. Bañuls, R. Blatt, J. Catani +17
Lattice gauge theories, which originated from particle physics in the context of Quantum Chromodynamics (QCD), provide an important intellectual stimulus to further develop quantum…
Synthetic gauge fields in synthetic dimensions
A. Celi, P. Massignan, J. Ruseckas +4
We describe a simple technique for generating a cold-atom lattice pierced by a uniform magnetic field. Our method is to extend a one-dimensional optical lattice into the "dimension…
Tunable multiple layered Dirac cones in optical lattices
Z. Lan, A. Celi, W. Lu +2
We show that multiple layered Dirac cones can emerge in the band structure of properly addressed multicomponent cold fermionic gases in optical lattices. The layered Dirac cones co…
Simulations of non-Abelian gauge theories with optical lattices
L. Tagliacozzo, A. Celi, P. Orland +2
Many phenomena occurring in strongly correlated quantum systems still await conclusive explanations. The absence of isolated free quarks in nature is an example. It is attributed t…
