Entanglement harvesting in buckled honeycomb lattices by vacuum fluctuations in a microcavity
Facundo Arreyes, Federico Escudero, Juan Sebastián Ardenghi +1
We study the entanglement harvesting between two identical buckled honeycomb lattices placed inside a planar microcavity. By applying time dependent perturbation theory, we obtain…

Federico Escudero
We develop a diagrammatic perturbation theory to account for the emergence of moiré bands in the continuum model of twisted bilayer graphene. Our framework is build upon treating t…
Designing Moiré Patterns by Strain
Federico Escudero, Andreas Sinner, Zhen Zhan +2
Experiments conducted on two-dimensional twisted materials have revealed a plethora of moiré patterns with different forms and shapes. The formation of these patterns is usually at…
Coulomb drag in metallic twisted bilayer graphene
Federico Escudero, Juan Sebastián Ardenghi
Strongly correlated phases in twisted bilayer graphene (TBG) typically arise as transitions from a state in which the system behaves as a normal metal. In such metallic regime, ele…
Coulomb drag between two graphene layers at different temperatures
Federico Escudero, Facundo Arreyes, Juan Sebastián Ardenghi
We theoretically study the Coulomb drag in graphene when there is a temperature difference between the layers. Within the degenerate limit for equal layer densities, we find that t…
A general formulation for the magnetic oscillations in two dimensional systems
Federico Escudero, Juan Sebastián Ardenghi, Paula Jasen
We develop a general formalism for the magnetic oscillations (MO) in two dimensional (2D) systems. We consider general 2D Landau levels, which may depend on other variable or indic…
