Junctions and superconducting symmetry in twisted bilayer graphene
Héctor Sainz-Cruz, Pierre A. Pantaleón, Vo Tien Phong +2
Junctions provide a wealth of information on the symmetry of the order parameter of superconductors. We analyze junctions between a scanning tunneling microscope (STM) tip and supe…

Comment on: Calculation of an Enhanced Symmetry Mode Induced by Higgs Oscillations in the Raman Spectrum of High-Temperature Cuprate Superconductors
L. Benfatto, C. Castellani, T. Cea
In a recent manuscript Phys. Rev. Lett. 127, 197001 (2021) Puviani et al. claim that the Higgs mode gives an enhancement of the Raman response in the symmetric Raman chann…

THz non-linear optical response in cuprates: predominance of the BCS response over the Higgs mode
Mattia Udina, Jacopo Fiore, Tommaso Cea +3
Recent experiments with strong THz fields in unconventional cuprates superconductors have clearly evidenced an increase of the non-linear optical response below the superconducting…
