Sign-Resolved Statistics and the Origin of Bias in Quantum Monte Carlo
Ryan Larson, Rubem Mondaini, Richard T. Scalettar
Quantum simulations are a powerful tool for exploring strongly correlated many-body phenomena. Yet, their reach is limited by the fermion sign problem, which causes configuration w…
Spin-orbit coupled periodic Anderson model: Kondo-Dirac semimetal and orbital-selective antiferromagnetic semimetal
Sebastião dos Anjos Sousa-Júnior, Julián Faúndez, Rubem Mondaini
We investigate the periodic Anderson model composed of an itinerant -band and a strongly localized -band, featuring on-site electron-electron interactions in the -orbitals…
From Bell Products to Greenberger-Horne-Zeilinger states: Quantum Memories via emergent Hamiltonians
Anubhab Sur, Qiujiang Guo, Rubem Mondaini
With the advent of exquisite quantum emulators, storing highly entangled many-body states becomes essential. While entanglement typically builds over time when evolving a quantum s…
Photodynamic melting of phase-reversed charge stripes and enhanced condensation
Jianhao Sun, Richard T. Scalettar, Rubem Mondaini
The interplay between charge stripes and pairing has long been a subject of scrutiny in a broad class of unconventional superconductors, as in some cases it is unclear whether this…
Non-Hermitian Haldane-Hubbard model: Effective description of an open system with balanced gain and loss
Tian-Cheng Yi, Rubem Mondaini
We study the correlated Haldane-Hubbard model with single-particle gain and loss, focusing on its non-Hermitian phase diagram and the ensuing non-unitary dynamic properties. The in…
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…
