Structure optimization in an off-lattice protein model
Hsiao-Ping Hsu, Vishal Mehra, Peter Grassberger
We study an off-lattice protein toy model with two species of monomers interacting through modified Lennard-Jones interactions. Low energy configurations are optimized using the pr…
A Growth-based Optimization Algorithm for Lattice Heteropolymers
Hsiao-Ping Hsu, Vishal Mehra, Walter Nadler +1
An improved version of the pruned-enriched-Rosenbluth method (PERM) is proposed and tested on finding lowest energy states in simple models of lattice heteropolymers. It is found t…
Growth Algorithms for Lattice Heteropolymers at Low Temperatures
Hsiao-Ping Hsu, Vishal Mehra, Walter Nadler +1
Two improved versions of the pruned-enriched-Rosenbluth method (PERM) are proposed and tested on simple models of lattice heteropolymers. Both are found to outperform not only the…
On the trapping reaction with mobile traps
Vishal Mehra, Peter Grassberger
We present Monte Carlo results for the two-species trapping reaction with diffusing and on lattices in one, two and three dimension. We use a novel algorithm wh…
Transition to Localization of Biased Walkers in a Randomly Absorbing Enviroment
Vishal Mehra, Peter Grassberger
We study biased random walkers on lattices with randomly dispersed static traps in one, two and three dimensions. As the external bias is increased from zero the system undergoes a…
Perfectly Translating Lattices on a Cylinder
Vishal Mehra, Jayme De Luca
We perform molecular dynamics simulations on an interacting electron gas confined to a cylindrical surface and subject to a radial magnetic field and the field of the positive back…
