Multiple Topological Haldane Phases for Symmetry-Protected Quantum Information Processing
João Pedro Gama D'Elia, Irene D'Amico, Thereza Paiva
Symmetry-protected topological phases have attracted significant interest at the fundamental level and as a potential platform for quantum information processing, owing to their pr…
The thermopower properties of interacting systems
M. A. Habitzreuter, Willdauany C. de Freitas da Silva, Rodrigo A. Fontenele +2
The Seebeck coefficient quantifies the voltage generated across a material in response to a temperature gradient. Recent studies have shown that strong electronic correlations can…
Women in Theoretical Quantum Physics in Brazil:demographics, career profiles, recognition, and leadership
Tatiana Pauletti, Paula Homem de Mello, Thereza Paiva +1
Gender imbalance in Physics remains a persistent global challenge, and Brazil is no exception. While women account for only 24% of Physics faculty in the country, their representat…
Specific heat and density anomaly in the Hubbard model
M. A. Habitzreuter, Willdauany C. de Freitas Silva, Eduardo O. Rizzatti +2
Understanding thermal properties of materials is fundamental to technological applications and to discovering new phenomena. In particular, advances in experimental techniques such…
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…
Topological Phase Transition in the Two-Leg Hubbard Model: Emergence of the Haldane Phase via Diagonal Hopping and Strong Interactions
João Pedro Gama D'Elia, Thereza Paiva
We investigate the two-leg Hubbard model with diagonal hopping to explore the interplay between geometrical frustration and strong electron-electron interactions. Using the Density…
