Weak first-order superfluid-solid quantum phase transitions.
We study superfluid-solid zero-temperature transitions in two-dimensional lattice boson-spin models using worm-algorithm Monte Carlo simulations. We observe that such transitions are typically first order with the exception of special high-symmetry points which require fine-tuning in the Hamiltonian parameter space. We present evidence that the superfluid-checkerboard solid and superfluid-valen...
متن کاملDynamics of Weak First Order Phase Transitions.
The dynamics of weak vs. strong first order phase transitions is investigated numerically for 2+1 dimensional scalar field models. It is argued that the change from a weak to a strong transition is itself a (second order) phase transition, with the order parameter being the equilibrium fractional population difference between the two phases at the critical temperature, and the control parameter...
متن کاملFrustrated Heisenberg antiferromagnets: fluctuation in- duced first order vs deconfined quantum criticality
– Recently it was argued that quantum phase transitions can be radically different from classical phase transitions with as a highlight the ’deconfined critical points’ exhibiting fractionalization of quantum numbers due to Berry phase effects. Such transitions are supposed to occur in frustrated (’J1-J2’) quantum magnets. We have developed a novel renormalization approach for such systems whic...
متن کاملDeconfined criticality critically defined
We describe characteristic physical properties of the recently introduced class of deconfined quantum critical points. Using some simple models, we highlight observables which clearly distinguish such critical points from those described by the conventional Landau-Ginzburg-Wilson framework: such a distinction can be made quite precisely even though both classes of critical points are strongly c...
متن کاملSuperfluid-superfluid phase transitions in a two-component Bose-Einstein condensate.
Depending on the Hamiltonian parameters, two-component bosons in an optical lattice can form at least three different superfluid phases in which both components participate in the superflow: a (strongly interacting) mixture of two miscible superfluids (2SF), a paired superfluid (PSF) vacuum, and (at a commensurate total filling factor) the super-counter-fluid (SCF) state. We study the universal...
