Dislocation-induced superfluidity in a model supersolid
D. Goswami, K. Dasbiswas, C. -D. Yoo +1
Motivated by recent experiments on the supersolid behavior of He, we study the effect of an edge dislocation in promoting superfluidity in a Bose crystal. Using Landau theory,…
Hydrodynamic theory of supersolids: Variational principle and effective Lagrangian
C. -D. Yoo, Alan T. Dorsey
We develop an effective low-energy, long-wavelength theory of a bulk supersolid--a putative phase of matter with simultaneous crystallinity and Bose condensation. Using conservatio…
Bound states of edge dislocations: The quantum dipole problem in two dimensions
K. Dasbiswas, D. Goswami, C. -D. Yoo +1
We investigate bound state solutions of the 2D Schrödinger equation with a dipole potential originating from the elastic effects of a single edge dislocation. The knowledge of thes…
Viscoelastic Behavior of Solid He
Chi-Deuk Yoo, Alan T. Dorsey
Over the last five years several experimental groups have reported anomalies in the temperature dependence of the period and amplitude of a torsional oscillator containing solid $^…
