Observation of Van Hove singularities in twisted graphene layers
Guohong Li, A. Luican, J. M. B. Lopes dos Santos +4
Electronic instabilities at the crossing of the Fermi energy with a Van Hove singularity in the density of states often lead to new phases of matter such as superconductivity, magn…

Emergence of robust gaps in 2D antiferromagnets via additional spin-1/2 probes
A. Ferreira, J. Viana Lopes, J. M. B. Lopes dos Santos
We study the capacity of antiferromagnetic lattices of varying geometries to entangle two additional spin-1/2 probes. Analytical modeling of the Quantum Monte Carlo data shows the…
