Colloquium: Quantum annealing and analog quantum computation
Arnab Das,Bikas K. Chakrabarti +1 more
TL;DR: The recent success in quantum annealing, i.e., optimization of the cost or energy functions of complex systems utilizing quantum fluctuations, is reviewed in this paper, where the concept is introduced in successive steps through studying the mapping of such computationally hard problems to classical spin-glass problems.
Book
Quantum Ising Phases and Transitions in Transverse Ising Models
TL;DR: In this article, the Transverse Ising Chain (pure system) and Transverse ising System in Higher Dimensions (pure systems) in higher dimensions (pure Systems) are presented.
Journal ArticleDOI
Statistical mechanics of money: how saving propensity affects its distribution
TL;DR: In this article, the authors consider a simple model of a closed economic system where the total money is conserved and the number of economic agents is fixed and investigate the effect of the saving propensity of the agents on the stationary or equilibrium probability distribution of money.
Journal ArticleDOI
Dynamic transitions and hysteresis
TL;DR: In this article, the authors present an overview of the ongoing research in dynamic hysteresis and transitions for pulsed and stochastically varying magnetic fields, as well as a nonzero average value of the variable undergoing such a transition.
Journal ArticleDOI
Pareto law in a kinetic model of market with random saving propensity
TL;DR: In this article, the authors have numerically simulated 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.
