Spiral antiferromagnets beyond the spin-wave approximation: frustrated and Heisenberg models in the honeycomb lattice
Andrea Di Ciolo, Juan Carrasquilla, Federico Becca +2
We examine the stability of classical states with a generic incommensurate spiral order against quantum fluctuations. Specifically, we focus on the frustrated spin-1/2 and Hei…

Nature of the phases in the frustrated XY model on the honeycomb lattice
Juan Carrasquilla, Andrea Di Ciolo, Federico Becca +2
We study the phase diagram of the frustrated XY model on the honeycomb lattice by using accurate correlated wave functions and variational Monte Carlo simulations. Our results sugg…
