Resonating valence bond pairing energy in graphene by quantum Monte Carlo
S. Azadi, A. Principi, T. D. Kühne +1
We determine the resonating-valence-bond (RVB) state in graphene using real-space quantum Monte Carlo with correlated variational wave functions. Variational and diffusion quantum…
A new scale anomaly in Dirac matter
Matteo Baggioli, Maxim N. Chernodub, Karl Landsteiner +2
The dynamics of Dirac semimetals is modeled at low energies by the massless Dirac Hamiltonian with the Fermi velocity replacing the velocity of light. The classical action is scale…
Quantum Monte Carlo study of the quasiparticle effective mass of the two-dimensional uniform electron liquid
S. Azadi, N. D. Drummond, A. Principi +2
The real-space variation quantum Monte Carlo (VMC) and diffusion quantum Monte Carlo (DMC) are used to calculate the quasiparticle energy bands and the quasiparticle effective mass…
Quantum Monte Carlo description of correlated electrons in two-dimensional FeSe
S. Azadi, A. Principi, R. V. Belosludov +2
An interesting question in physics is how the correlation energy of atoms evolves upon forming a solid. Here, we address this problem for a specific case of double-layer FeSe. We u…
Spin and Charge Transport Mediated by Fractionalized Excitations
Alexey Ermakov, Alessandro Principi
We study charge and spin transport in systems composed of itinerant electrons and localized magnetic moments of a Kitaev quantum spin liquid (QSL) phase. For example, $α-{\rm RuCl}…
