Nonequilibrium dynamics of one-dimensional hard-core anyons following a quench: Complete relaxation of one-body observables
Tod M. Wright, Marcos Rigol, Matthew J. Davis +1
We demonstrate the role of interactions in driving the relaxation of an isolated integrable quantum system following a sudden quench. We consider a family of integrable hard-core l…
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…
Linked-cluster expansion for the Green's function of the infinite-U Hubbard model
Ehsan Khatami, Edward Perepelitsky, Marcos Rigol +1
We implement a highly efficient strong-coupling expansion for the Green's function of the Hubbard model. In the limit of extreme correlations, where the onsite interaction is infin…
Driven dipole oscillations and the lowest energy excitations of strongly interacting lattice bosons in a harmonic trap
Kai He, Jennifer Brown, Stephan Haas +1
We show that the analysis of the time evolution of the occupation of site and momentum modes of harmonically trapped lattice hard-core bosons, under driven dipole oscillations, all…
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…
Finite-temperature properties of strongly correlated fermions in the honeycomb lattice
Baoming Tang, Thereza Paiva, Ehsan Khatami +1
We study finite-temperature properties of strongly interacting fermions in the honeycomb lattice using numerical linked-cluster expansions and determinantal quantum Monte Carlo sim…
