Phase diagram of Josephson junction arrays with capacitive disorder
We study the phase diagram at finite temperature of Josephson junction arrays with capacitive disorder (i.e., random offset charges and/or random charging energies): in the limit of large particle numbers per junction, this is a remarkable physical realization of the disordered boson Hubbard model. By using a mean-field approximation, we compute the average free energy and the equation for the ...

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 کاملNumerical Determination of the Forming Limit Diagram for 304 Stainless Steel Based on Phase Change in Deep Drawing Process
Up to now a large number of models have been developed to measure or predict the damage in equipments. Some of these models have been implemented in ABAQUS software. To implement damage parameters in the software, it is necessary to perform complex and expensive practical tests. One of these damage models is Forming Limit Diagram (FLD).The purpose of this research is deriving required parameter...
متن کاملJosephson Junction Materials Research Using Phase Qubits
At present, the performance of superconducting qubits is limited by decoherence. Strong decoherence of phase qubits is associated with spurious microwave resonators residing within the Josephson junction tunnel barrier [1]. In this work, we investigate three different fabrication techniques for producing tunnel junctions that vary the properties of the superconductor-insulator interface. Throug...
