Quantum Monte Carlo simulations of highly frustrated magnets in a cluster basis: The two-dimensional Shastry-Sutherland model

Andreas Honecker, Lukas Weber, Philippe Corboz +2

Quantum Monte Carlo (QMC) simulations constitute nowadays one of the most powerful methods to study strongly correlated quantum systems, provided that no "sign problem" arises. How…

Accuracy of the typicality approach using Chebyshev polynomials

H. Schlüter, F. Gayk, H. -J. Schmidt +2

Trace estimators allow to approximate thermodynamic equilibrium observables with astonishing accuracy. A prominent representative is the finite-temperature Lanczos method (FTLM) wh…

Quantum Monte Carlo simulations in the trimer basis: first-order transitions and thermal critical points in frustrated trilayer magnets

L. Weber, A. Honecker, B. Normand +3

The phase diagrams of highly frustrated quantum spin systems can exhibit first-order quantum phase transitions and thermal critical points even in the absence of any long-ranged ma…

Magnetism of magic-angle twisted bilayer graphene

Javad Vahedi, Robert Peters, Ahmed Missaoui +2

We investigate magnetic instabilities in charge-neutral twisted bilayer graphene close to so-called "magic angles" using a combination of real-space Hartree-Fock and dynamical mean…
