Superfluidity without charge order in the attractive Hubbard model on the kagome lattice
Xiaodong Jin, Yingping Mou, Rubem Mondaini
Using auxiliary-field quantum Monte Carlo simulations, we study the zero-temperature attractive Hubbard model on the kagome lattice at various relevant electronic fillings. The low…
Real-space topology and charge order in the Haldane-Holstein Model
Sebastião dos Anjos Sousa-Júnior, Julián Faúndez, Tarik P. Cysne +2
We study the half-filled Haldane-Holstein model, where a paradigmatic Chern insulator is coupled to fully dynamical phonons, and provide an unbiased characterization of how retarde…
Enhancement of charge correlations and real-space topological marker on an interacting non-Hermitian Su-Schrieffer-Heeger model
Sebastião dos A. Sousa-Júnior, Pedro B. Melo, Rubem Mondaini +2
We investigate the interacting non-Hermitian Su-Schrieffer-Heeger (SSH) model, focusing on the interplay between topology and charge ordering. Using a real-space topological marker…
The Two Orbital, Interacting Hatano-Nelson Model
Jonah Huang, Rubem Mondaini, Nancy Aggarwal +1
The single orbital, one-dimensional, Hatano-Nelson Hamiltonian provides deep insight into the physics of non-Hermiticity, resulting from asymmetric left/right hopping, and its conn…
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…
Fock space prethermalization and time-crystalline order on a quantum processor
Zehang Bao, Zitian Zhu, Yang-Ren Liu +31
Periodically driven quantum many-body systems exhibit a wide variety of exotic nonequilibrium phenomena and provide a promising pathway for quantum applications. A fundamental chal…
