Vortices in high-temperature superconductors
With the high-temperature superconductors a qualitatively new regime in the phenomenology of type-II superconductivity can be accessed. The key elements governing the statistical mechanics and theExpand

Superconductor-Insulator transition and energy localization
We develop an analytical theory for generic disorder-driven quantum phase transitions. We apply this formalism to the superconductor-insulator transition and we briefly discuss the applications toExpand

Protected qubits and Chern-Simons theories in Josephson junction arrays
We present general symmetry arguments that show the appearance of doubly degenerate states protected from external perturbations in a wide class of Hamiltonians. We construct the simplest spinExpand

Hidden supersymmetry of stochastic dissipative dynamics
It is shown that the generating functional of dissipative dynamics in a potential force field can be reduced to the form of the functional integral of Euclidian supersymmetric field theory. TheExpand

Environmentally decoupled sds -wave Josephson junctions for quantum computing
Quantum computers have the potential to outperform their classical counterparts in a qualitative manner, as demonstrated by algorithms which exploit the parallelism inherent in the time evolution ofExpand

Collapse of superconductivity in a hybrid tin-graphene Josephson junction array
When a Josephson junction array is built with hybrid superconductor/metal/superconductor junctions, a quantum phase transition from a superconducting to a two-dimensional (2D) metallic ground stateExpand

Pinning and creep in layered superconductors
Abstract The thermal- and disorder-induced effects in the mixed state of a layered high- T c superconductor (in a field H ‖ c ) are studied. The flux line lattice is of a quasi-2D type atExpand

Topologically protected quantum bits using Josephson junction arrays
All physical implementations of quantum bits (or qubits, the logical elements in a putative quantum computer) must overcome conflicting requirements: the qubits should be manipulable through externalExpand

Eigenfunction fractality and pseudogap state near the superconductor-insulator transition.
We develop a theory of a pseudogap state appearing near the superconductor-insulator (SI) transition in strongly disordered metals with an attractive interaction. We show that such an interactionExpand

Fractal superconductivity near localization threshold
We develop a semi-quantitative theory of electron pairing and resulting superconductivity in bulk "poor conductors" in which Fermi energy $E_F$ is located in the region of localized states not so farExpand
