Quantum transport in a non-Hermitian 1D synthetic lattice: from quantum Zeno reflection to near-perfect absorption
Emmanuel. D. Mercado-Gutiérrez, W. Xu, E. Gvozdiovas +5
We experimentally explore the absorption of a propagating wavepacket impinging upon a dissipative region in an engineered quantum system. We employ a 1D non-Hermitian synthetic lat…
Quantum Kramers-Henneberger Transformation
Javier Argüello-Luengo, Javier Rivera-Dean, Philipp Stammer +2
The classical Kramers-Henneberger transformation connects, via a series of unitary transformations, the dynamics of a quantum particle of mass located in a trap at position $α(…
Probing spontaneously symmetry-broken phases with spin-charge separation through noise correlation measurements
Kerman Gallego-Lizarribar, Sergi Julià-Farré, Maciej Lewenstein +3
Spontaneously symmetry-broken (SSB) phases are locally ordered states of matter characterizing a large variety of physical systems. Because of their specific ordering, their presen…
Quantized Thouless pumps protected by interactions in dimerized Rydberg tweezer arrays
Sergi Julià-Farré, Javier Argüello-Luengo, Loïc Henriet +1
We study Thouless pumps, i.e., adiabatic topological transport, in an interacting spin chain described by the dimerized XXZ Hamiltonian. In the noninteracting case, quantized Thoul…
Synthetic dimensions for topological and quantum phases: Perspective
Javier Argüello-Luengo, Utso Bhattacharya, Alessio Celi +8
In this Perspective article we report on recent progress on studies of synthetic dimensions, mostly, but not only, based on the research realized around the Barcelona groups (ICFO,…
Entanglement and squeezing of the optical field modes in high harmonic generation
Philipp Stammer, Javier Rivera-Dean, Andrew S. Maxwell +5
Squeezing of optical fields, used as a powerful resource for many applications, and the radiation properties in the process of high harmonic generation have thus far been considere…
Eigenstate Thermalization and its breakdown in Quantum Spin Chains with Inhomogeneous Interactions
Ding-Zu Wang, Hao Zhu, Jian Cui +5
The eigenstate thermalization hypothesis (ETH) is a successful theory that establishes the criteria for ergodicity and thermalization in isolated quantum many-body systems. In this…
Competing order in two-band Bose-Hubbard chains with extended-range interactions
Yuma Watanabe, Utso Bhattacharya, Ravindra W. Chhajlany +3
Motivated by the recent progress in realizing and controlling extended Bose-Hubbard systems using excitonic or atomic devices, the present Letter theoretically investigates the cas…
Stabilization of Hubbard-Thouless pumps through nonlocal fermionic repulsion
Javier Argüello-Luengo, Manfred J. Mark, Francesca Ferlaino +3
Thouless pumping represents a powerful concept to probe quantized topological invariants in quantum systems. We explore this mechanism in a generalized Rice-Mele Fermi-Hubbard mode…
Analog simulation of high harmonic generation in atoms
Javier Argüello-Luengo, Javier Rivera-Dean, Philipp Stammer +4
The demanding experimental access to the ultrafast dynamics of materials challenges our understanding of their electronic response to applied strong laser fields. For this purpose,…
A generalized multi-scale entanglement renormalization ansatz: more accurate conformal data from a critical lattice model
Javier Argüello-Luengo, Ashley Milsted, Guifre Vidal
The multi-scale entanglement renormalization ansatz (MERA) provides a natural description of the ground state of a quantum critical Hamiltonian on the lattice. From an optimized ME…
Tuning long-range fermion-mediated interactions in cold-atom quantum simulators
Javier Argüello-Luengo, Alejandro González-Tudela, Daniel González-Cuadra
Engineering long-range interactions in cold-atom quantum simulators can lead to exotic quantum many-body behavior. Fermionic atoms in ultracold atomic mixtures can act as mediators…
Optomechanical strong coupling between a single cavity photon and a single atom
Javier Argüello-Luengo, Darrick E. Chang
Single atoms coupled to a cavity offer unique opportunities as quantum optomechanical devices because of their small mass and strong interaction with light. A particular regime of…
