Exact vortex decomposition of the shift current
Matias Castro Schnaidt, Felipe Perez Riffo, Juan M. Florez +1
Does any integer survive in the shift current, and does the Chern number control its sign? We show that the shift vector is a singular field on the Brillouin torus. Its curl has tw…
Topographic Disorder, Wind Coupling, and Directional Fire Spread: Critical Behavior in a Terrain-Weighted Forest Fire Model
Juan M. Florez, Eric Suárez Morell, Cristian Millan +1
We introduce the Terrain-Weighted Forest Fire Model (TFFM), a lattice model in which fire spreads on a spatially correlated Gaussian height field with the asymmetric bond probabili…
Symmetry selection rule for the band-edge shift current in two dimensions
Felipe Pérez Riffo, Matías Castro, Leonor Chico +2
The shift current is the intrinsic bulk photovoltaic response of a crystal without an inversion center. In graphene multilayers, calculations report large band-edge shift currents…
Reaching maximum efficiency in quantum Stirling engines using multilayer graphene
Bastian Castorene, Francisco J. Peña, Eric Suárez Morell +4
In this work, quantum Stirling engines based on monolayer, AB-stacked bilayer, and ABC-stacked trilayer graphene under perpendicular magnetic fields are analyzed. Performance maps…
Unveiling the Electronic Origin of Anomalous Contact Conductance in Twisted Bilayer Graphene
Kevin J. U. Vidarte, Caio Lewenkopf, F. Crasto de Lima +3
This study theoretically investigates the contact conductance in twisted bilayer graphene (TBG), addressing recent experimental observations from scanning tunneling microscopy (STM…
Engineering Altermagnetism via Layer Shifts and Spin Order in Bilayer MnPS
J. W. González, T. Brumme, E. Suárez Morell +1
Altermagnetic materials combine compensated magnetic order with momentum-dependent spin splitting, offering a fundamentally new route for spintronic functionality beyond convention…
Stoner ferromagnetism in low-angle twisted bilayer graphene at three-quarters filling
Kevin J. U. Vidarte, Felipe Pérez Riffo, Eric Suárez Morell +1
We present a theoretical investigation of the magnetic properties exhibited by twisted bilayer graphene (TBG) systems with small twist angles, where the appearance of flat miniband…
VC-based lithium batteries: The influence of magnetic phase and Hubbard interaction
Jhon W. González, Sanber Vizcaya, Eric Suárez Morell
MXenes are a family of two-dimensional materials that could be attractive for use as electrodes in lithium batteries due to their high specific capacity. For this purpose, it is ne…
Theory of magnetism in the van der Waals magnet CrI3
Rodrigo Jaeschke-Ubiergo, Eric Suarez Morell, Alvaro Sebastian Nunez
We study the microscopical origin of anisotropic ferromagnetism in the van der Waals magnet CrI3. We conclude that the nearest neighbors exchange is well described by the Heisenber…
Edge states of moiré structures in graphite
Eric Suárez Morell, P. Vargas, P. Häberle +2
We address the origin of bead-like edge states observed by scanning tunneling microscopy (STM) in moiré patterns of graphite. Low-bias scanning tunneling spectroscopy measurements…
