Vortex dynamics in two-dimensional supersolids
Chi-Deuk Yoo, Alan T. Dorsey
We investigate the dynamics of quantized vortices in a model two-dimensional supersolid. Starting from an effective action that captures the dynamics of the superfluid condensate a…
The role of viscoelastic contrast in orientation selection of block copolymer lamellar phases under oscillatory shear
Chi-Deuk Yoo, Jorge Vinals
The mesoscale rheology of a lamellar phase of a block copolymer is modeled as a structured fluid of uniaxial symmetry. The model predicts a viscoelastic response that depends on th…
Anisotropic diffusion and hydrodynamic effects on lamellar relaxation and grain boundary motion in a model of a block copolymer
Chi-Deuk Yoo, Jorge Vinals
We consider the effects of anisotropic diffusion and hydrodynamic flows on the relaxation time scales of the lamellar phase of a diblock copolymer. We first extend the two-fluid mo…
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…
