Quantum Phase Transitions in a Finite System
An important issue concerning quantum phase transitions in mesoscopic systems is to understand the modifications at criticality due to their finite number of constituents. In the present contribution we study this question in connection with nuclei exemplifying a finite system undergoing a shape-phase transition. We employ the interacting boson model (IBM) [1] which describes low-lying quadrupo...
متن کاملFinite Temperature Dynamics near Quantum Phase Transitions
We review the non-zero temperature relaxational dynamics of quantum systems near a zero temperature, second-order phase transition. We begin with the quantum Ising chain, for which universal and exact results for the relaxation rates can be obtained in all the distinct limiting regimes of the phase diagram. Next, we describe the crossovers in the electron spectral function near a transition inv...
متن کاملQuantum Shape-Phase Transitions in Finite Nuclei
Quantum phase transitions are structural changes occurring at zero temperature as a function of a coupling constant and driven by quantum fluctuations. An example is the phase transition between different shapes of nuclei for which the equilibrium deformation plays the role of an order parameter. A proper description of such phase transitions necessitates the inclusion of correlation effects be...
متن کاملDynamical non-ergodic scaling in continuous finite-order quantum phase transitions
We investigate the emergence of universal dynamical scaling in quantum critical spin systems adiabatically driven out of equilibrium, with emphasis on quench dynamics which involves non-isolated critical points (i.e., critical regions) and cannot be a priori described through standard scaling arguments nor time-dependent perturbative approaches. Comparing to the case of an isolated quantum crit...
متن کاملVoltage Induced Dynamical Quantum Phase Transitions in Exciton Condensates
We explore non-analytic quantum phase dynamics of dipolar exciton condensates formed in a system of 1D quantum layers subjected to voltage quenches. We map the exciton condensate physics on to the pseudospin ferromagnet model showing an additional oscillatory metastable and paramagnetic phase beyond the well-known ferromagnetic phase by utilizing a time-dependent, nonperturbative theoretical mo...
