Non-equilibrium Dynamics of Quantum Systems: Order Parameter Evolution, Defect Generation, and Qubiymmetry of the ground state of a quantum system changes in a fundamental way; such a point can be accessed by changing some parameter, say λ, in the Hamiltonian governing the system. The change in the ground state across a QCP is mediated by quantum fluctuations. Unlike conventional thermal critical

Defect Production Due to Quenching Through a Multicritical Point and Along a Gapless Line,m system when quenchedvery fast [3, 4] or slowly across a quantum critical point [5–7] has attracted the attention of several groups recently. The possibility of experimental realizations of quantum dynamics in spin-1 Bose condensates [8] and atoms trapped in optical lattices [9–12] has led to an up

,Quench Dynamics of Quantum and Classical Ising Chains: From the Viewpoint of the Kibble–Zurek Mechaon, the correlation length and the relaxation timediverge at the critical point. Hence it takes infinitely long time for the state to evolve from a disordered state to an ordered state by lowering the temperature. Such a quasi-static motion of the state is ideal. However, a motion of a state by lowe

Influence of Local Moment Fluctuations on the Mott Transition, is driven by on-site electron–electron repulsion (see [7] for a review). Although the appearance of a Mott gapis clearly a charge-related effect, magnetism is expected to play a key role in elucidating the true nature of this phase transition. Indeed, since the Mott insulating state is purely param

Signatures of Quantum Phase Transitions via Quantum Information Theoretic Measures,r external magnetic field [1, 2]. In a QPT, the ground state wave function undergoes qualitative changes at the transition point. The transition is driven by quantum fluctuations whereas ordinary phase transitions occurring at nonzero temperatures are driven by thermal fluctuations. Like a thermal p
