Excess vibrational modes of a crystal in an external non-affine field
Saswati Ganguly, Surajit Sengupta
Thermal displacement fluctuations in a crystal may be classified as either "affine" or "non-affine". While the former couples to external stress with familiar consequences, the res…
Equilibrium and dynamic pleating of a crystalline bonded network
Saswati Ganguly, Jürgen Horbach, Peter Sollich +3
We describe a phase transition that gives rise to structurally non-trivial states in a two-dimensional ordered network of particles connected by harmonic bonds. Monte Carlo simulat…
Amorphization of a crystalline solid by plastic deformation
Saswati Ganguly, Juergen Horbach, Peter Sollich +2
We demonstrate that plastic deformation in solids is associated with a dynamic transition that is reminiscent to the transition from a superconducting to a mixed phase in Type II s…
