Phase transitions in the one-dimensional frustrated quantum XY model and Josephson-junction ladders
A one-dimensional quantum version of the frustrated XY (planar rotor) model is considered which can be physically realized as a ladder of Josephsonjunctions at half a flux quantum per plaquette. This system undergoes a superconductor to insulator transition at zero temperature as a function of charging energy. The critical behavior is studied using a Monte Carlo transfer matrix applied to the p...
متن کاملDecoupling in the 1D frustrated quantum XY model and Josephson junction ladders: Ising critical behavior
A generalization of the one-dimensional frustrated quantum XY model is considered in which the inter and intra-chain coupling constants of the two infinite XY (planar rotor) chains have different strengths. The model can describe the superconductor to insulator transition due to charging effects in a ladder of Josephson junctions in a magnetic field with half a flux quantum per plaquette. From ...
متن کاملQuantum Phase Transitions in Josephson Junction Arrays
In this chapter we review the quantum phase transitions and transport properties of low-capacitance Josephson junction arrays. We will present the models and introduce the relevant topological excitations. The phase diagram depends in a very rich way on various control parameters. We will discuss the universality or or absence of universality of the transport properties at the quantum phase tra...

متن کاملQuantum 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...
