A solvable quantum antiferromagnet model
Bikas K. Chakrabarti, Jun-ichi Inoue
We introduce a quantum antiferromagnet model, having exactly soluble thermodynamic properties. It is an infinite range antiferromagnetic Ising model put in a transverse field. The…
Competing field pulse induced dynamic transition in Ising models
Arnab Chatterjee, Bikas K. Chakrabarti
The dynamic magnetization-reversal phenomena in the Ising model under a finite-duration external magnetic field competing with the existing order for has been discussed.…
Tranverse Ising Model, Glass and Quantum Annealing
Bikas K. Chakrabarti, Arnab Das
We introduce the transverse Ising model as a prototype for discussing quantum phase transition. Next we introduce Suzuki-Trotter formalism to show the correspondence between -di…
Precursors of catastrophic failures
Srutarshi Pradhan, Bikas K. Chakrabarti
We review here briefly the nature of precursors of global failures in three different kinds of many-body dynamical systems. First, we consider the lattice models of self-organised…
Quantum Spin Glass Phase Boundary in (+/-)J Transverse Field Ising Systems
Arnab Das, Amit Dutta, Bikas K. Chakrabarti
Here we study zero temperature quantum phase transition driven by the transverse field for random Ising model on chain and square lattice. We present some analytical result…
The Mean Distance to the n-th Neighbour in a Uniform Distribution of Random Points: An Application of Probability Theory
Pratip Bhattacharyya, Bikas K. Chakrabarti
We study different ways of determining the mean distance between a reference point and its -th neighbour among random points distributed with uniform density in a …
