Snell's law for particles moving on piecewise homogeneous two dimensional surface with linear boundaries
Pratik Mandrekar, Toby Joseph
We study the properties of least time trajectories for particles moving on a two dimensional surface which consists of piecewise homogeneous regions. The particles are assumed to m…

Structure and Magnetization of Two-Dimensional Vortex Arrays in the Presence of Periodic Pinning
Toby Joseph, Chandan Dasgupta
Ground-state properties of a two-dimensional system of superconducting vortices in the presence of a periodic array of strong pinning centers are studied analytically and numerical…

Continuous Melting of a "Partially Pinned" Two-Dimensional Vortex Lattice in a Square Array of Pinning Centers
Toby Joseph, Chandan Dasgupta
The structure and equilibrium properties of a two-dimensional system of superconducting vortices in a periodic pinning potential with square symmetry are studied numerically. For a…
