Multispin probes for thermometry in the strong-coupling regime

M Brenes, D Segal - Physical Review A, 2023 - APS
We study the sensitivity of thermometric probes that are composed of N spins coupled to a
sample prepared at temperature T. Our analysis extends beyond the weak-coupling limit into …

Kondo effect in twisted bilayer graphene

AS Shankar, DO Oriekhov, AK Mitchell, L Fritz - Physical Review B, 2023 - APS
The emergence of flat bands in twisted bilayer graphene at the magic angle can be
understood in terms of a vanishing Fermi velocity of the Dirac cone. This is associated with …
