Impact of electrostatic fields in layered crystalline BCS superconductors
Luca Chirolli, Tommaso Cea, Francesco Giazotto
Motivated by recent experiments reporting the suppression of the critical current in superconducting Dayem bridges by the application of strong electrostatic fields, in this work w…
Heterostrain rules the flat-bands in magic-angle twisted graphene layers
F. Mesple, A. Missaoui, T. Cea +5
The moiré of twisted graphene bilayers can generate flat bands in which charge carriers do not posses enough kinetic energy to escape Coulomb interactions with each other leading t…
Band structure of twisted bilayer graphene on hexagonal boron nitride
Tommaso Cea, Pierre A. Pantaleon, Francisco Guinea
The effect of an hexagonal boron nitride (hBN) layer close aligned with twisted bilayer graphene (TBG) is studied. At sufficiently low angles between twisted bilayer graphene and h…
Band structure and insulating states driven by the Coulomb interaction in twisted bilayer graphene
Tommaso Cea, Francisco Guinea
We analyze the phase diagram of twisted graphene bilayers near a magic angle. We consider the effect of the long range Coulomb interaction, treated within the self consistent Hartr…
