BCS-BEC crossover in trapped one-dimensional Fermi-Hubbard chains: entanglement and correlation signatures from DMRG and effective-pairing theory
G. Diniz, I. M. Carvalho, M. Sanino +2
Confined ultracold atoms in optical lattices provide a versatile platform for simulating lattice models of strongly correlated quantum systems, where pairing phenomena and superflu…
Single-site diagonal quantities capture off-diagonal long-range order
M. Sanino, I. D'Amico, V. V. França +1
Quantum phase transitions are typically marked by changes in quantum correlations across various spatial scales within the system. A key challenge lies in the fact that experimenta…
Controlling quantum phases with step-like electric potentials in one-dimensional Hubbard systems
D. Arisa, R. M. Dos Santos, Isaac M. Carvalho +1
Quantum systems under electric potentials provide a powerful framework for uncovering and controlling novel quantum phases, especially in low-dimensional systems with strong correl…
Single-site entanglement as a marker for quantum phase transitions at non-zero temperatures
Willdauany C. de Freitas Silva, Andressa R. Medeiros-Silva, Rubem Mondaini +2
Entanglement has been widely investigated in condensed matter systems since they are considered good candidates for developing quantum technologies. Additionally, entanglement is a…
Entanglement as a topological marker in harmonically confined attractive Fermi-Hubbard chains
Marina Sanino, Isaac Carvalho, Vivian França
We investigate the single-site von Neumann entropy along a harmonically confined superfluid chain, as described by the one-dimensional fermionic Hubbard model with strongly attract…
Entanglement in disordered superfluids: the impact of density, interaction and harmonic confinement on the Superconductor-Insulator transition
G. A. Canella, V. V. França
We investigate the influence of density, interaction and harmonic confinement on the superfluid to insulator transition (SIT) in disordered fermionic superfluids described by the o…
Entanglement and exotic superfluidity in spin-imbalanced lattices
Vivian V. França
We investigate the properties of entanglement in one-dimensional fermionic lattices at the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superfluid regime. By analyzing occupation probab…
Stability and entanglement in optical-atomic amplification of trapped atoms: the role of atomic collisions
V. V. França, G. A. Prataviera
Atomic collisions are included in an interacting system of optical fields and trapped atoms allowing field amplification. We study the effects of collisions on the system stability…
