Theory of resonantly enhanced photo-induced superconductivity
Eckhardt, S. Chattopadhyay, D. M. Kennes, E. A. Demler, M. A. Sentef & M. H. Michael Nat. Commun. 15 , 2300 (2024) Optical driving of materials has emerged as a versatile tool to control their properties [...] light-induced superconductivity concretely proposing a setup consisting of a graphene-hBN-SrTiO 3 heterostructure, for which we estimate a superconducting T c that may be achieved upon driving the system [...] into a non-thermal state. We find this phenomenon to be resonantly amplified when tuning the boson’s frequency close to the energy difference between the two electronic bands. This result offers a simple
