The lower bound of barrier-energy in spin glasses: a calculation of the exponent on hierarchical lattice
A. Bhattacharyay
We argue that the lower bound to the barrier energy to flip an up/down spin domain embedded in a down/up spin environment for Ising spin glass is independent of the size of the sys…

Harmonic oscillator states as oscillating localized structures near Hopf-Turing instability boundary
A. Bhattacharyay
A set of coupled complex Ginzburg-landau type amplitude equations which operates near a Hopf-Turing instability boundary is analytically investigated to show localized oscillatory…

Phase instabilities generated by parametric modulation in reaction diffusion systems
A. Bhattacharyay, J. K. Bhattacherjee
Effect of external periodic force on an oscillatory order in a reaction diffusion system (Gierer Meinhardt model) has been investigated. The 2:1 resonance situation is found suscep…
