First principles calculations of electric-field-driven topological phase transitions in silicene, germanene and stanene
Julián Antonio Villarreal Murúa, Pablo Roura-Bas, Javier Daniel Fuhr +1
The emergence of two-dimensional topological materials, particularly the group-14 monolayers known as silicene, germanene, and stanene has opened promising pathways for next-genera…
Exact analytical edge states in the extended Su-Schrieffer-Heeger model
P. A. Grizzi, A. A. Aligia, P. Roura-Bas
We investigate the topology of the different phases of the extended Su-Schrieffer-Heeger (eSSH) model, which includes hopping processes between translationally inequivalent atoms b…
Thermoelectric Signatures of Kondo Physics in Geometry-Tunable Double Quantum Dots
Diego Perez Daroca, Pablo Roura-Bas
The equilibrium thermoelectric and spectral properties of a double quantum dot system are investigated, with the geometry continuously tuned from series to parallel via a parameter…
Role of asymmetry in thermoelectric properties of a double quantum dot out of equilibrium
Diego Perez Daroca, Pablo Roura-Bas, Armando A. Aligia
We investigate the thermoelectric properties of a double quantum dot system coupled to two metallic reservoirs, focusing on two main effects: (i) the influence of coupling asymmetr…
Charge and heat pumping in the Rice-Mele chain at finite temperature
P. Roura-Bas, A. A. Aligia
It is well known that quantized topological charge pumping takes place in the half filled Rice-Mele chain performing a closed cycle in parameter space. We extend previous studies t…
A Brillouin torus decomposition for two-dimensional topological insulators
F. Kordon, J. Fernández, P. Roura-Bas
Two-band Chern insulators are topologically classified by the Chern number, , which is given by the integral of the Berry curvature of the occupied band over the Brillouin torus…
