Scar-Driven Shape-Changes of Virus Capsids
Alfredo Iorio, Siddhartha Sen
We propose that certain patterns (scars) -- theoretically and numerically predicted to be formed by electrons arranged on a sphere to minimize the repulsive Coulomb potential (the…
Bound States in Gapped Graphene with Impurities : Effective Low-Energy Description of Short-Range Interactions
Kumar S. Gupta, Siddhartha Sen
We obtain a novel bound state spectrum of the low energy excitations near the Fermi points of graphene in the presence of a charge impurity. The effects of possible short range int…
Do quantum effects hold together DNA condensates?
Alfredo Iorio, Samik Sen, Siddhartha Sen
The classical electrostatic interaction between DNA molecules in water in the presence of counterions is reconsidered and we propose it is governed by a modified Poisson-Boltzmann…
Bound States in Graphene
Kumar S. Gupta, Siddhartha Sen
We present a quantum analysis of the massless excitations in graphene with a charge impurity. When the effective charge exceeds a certain critical value, the spectrum is quantized…
