Symmetry selection rule for the band-edge shift current in two dimensions
Felipe Pérez Riffo, Felipe Pérez Riffo, Matías Castro +5
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…
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…
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), providing a theoretical explanation for recent experimental observations from scann…
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…
