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…

Hopf-Turing mixed mode and pattern selection in reaction diffusion systems
A. Bhattacharyay
The amplitude equation of Gierer-Mainhardt model has been actually derived near the boundary abuot which Turing and Hopf modes exist. In a parameter region where Hopf-Turing mixed…
