Competing orders II: the doped quantum dimer model
Leon Balents, Lorenz Bartosch, Anton Burkov +2
We study the phases of doped spin S=1/2 quantum antiferromagnets on the square lattice, as they evolve from paramagnetic Mott insulators with valence bond solid (VBS) order at zero…
Fractional ac Josephson effect in unconventional superconductors
Hyok-Jon Kwon, K. Sengupta, Victor M. Yakovenko
For certain orientations of Josephson junctions between two p_x-wave or two d-wave superconductors, the subgap Andreev bound states produce a 4pi-periodic relation between the Jose…
Quench dynamics across quantum critical points
K. Sengupta, Stephen Powell, Subir Sachdev
We study the quantum dynamics of a number of model systems as their coupling constants are changed rapidly across a quantum critical point. The primary motivation is provided by th…
Competing density-wave orders in a one-dimensional hard-boson model
Paul Fendley, K. Sengupta, Subir Sachdev
We describe the zero-temperature phase diagram of a model of bosons, occupying sites of a linear chain, which obey a hard-exclusion constraint: any two nearest-neighbor sites may h…
