Stress relaxation in a perfect nanocrystal by coherent ejection of lattice layers
Abhishek Chaudhuri, Surajit Sengupta, Madan Rao
We show that a small crystal trapped within a potential well and in contact with its own fluid, responds to large compressive stresses by a novel mechanism -- the transfer of compl…
Probing Disordered Substrates by Imaging the Adsorbate in its Fluid Phase
Ankush Sengupta, Surajit Sengupta, Gautam I. Menon
Several recent imaging experiments access the equilibrium density profiles of interacting particles confined to a two-dimensional substrate. When these particles are in a fluid pha…
Comment on "Memory Effects in an Interacting Magnetic Nanoparticle System" by Sun et. al, prl, 91, 167206 (2003)
S. Chakravarty, A. Frydman, M. Bandyopadhyay +2
In this Comment we report a phenomenon identical to that observed in ({Y. Sun, M. B. Salamon, K. Garnier and R. S. Averback, Phys. Rev. Lett. 91, 167206 (2003)}) for systems of NiF…
A Kinetics Driven Commensurate - Incommensurate Transition
Abhishek Chaudhuri, P. A. Sreeram, Surajit Sengupta
The steady state structure of an interface in an Ising system on a square lattice placed in a {\em non-uniform} external field, shows a commensurate -incommensurate transition driv…
A numerical renormalization group study of laser induced freezing
Debasish Chaudhuri, Surajit Sengupta
We study the phenomenon of laser induced freezing, within a numerical renormalization scheme which allows explicit comparison with a recent defect mediated melting theory. Precise…
Constrained deformation of a confined solid: a strain induced crystal-smectic transition
Debasish Chaudhuri, Surajit Sengupta
We report results of computer simulations of two-dimensional hard disks confined within a quasi one-dimensional ``hard-wall'' channel, a few atomic radii wide. Starting from a comm…
