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…
Money in Gas-Like Markets: Gibbs and Pareto Laws
Arnab Chatterjee, Bikas K. Chakrabarti, S. S. Manna
We consider the ideal-gas models of trading markets, where each agent is identified with a gas molecule and each trading as an elastic or money-conserving (two-body) collision. Unl…
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…
Prediction Possibility in the Fractal Overlap Model of Earthquakes
Srutarshi Pradhan, Pinaki Choudhuri, Bikas K. Chakrabarti
The two-fractal overlap model of earthquake shows that the contact area distribution of two fractal surfaces follows power law decay in many cases and this agrees with the Guttenbe…
Magnitude distribution of earthquakes: Two fractal contact area distribution
Srutarshi Pradhan, Bikas K. Chakrabarti, Purussatam Ray +1
The `plate tectonics' is an observed fact and most models of earthquake incorporate that through the frictional dynamics (stick-slip) of two surfaces where one surface moves over t…
