Crossovers between superconducting symmetry classes
Crossovers superconducting symmetry classes random matrix theory supersymmetric sigma-model
2011/7/28
Abstract: We study the average density of states in a small metallic grain coupled to two superconductors with the phase difference $\pi$, in a magnetic field. The spectrum of the low-energy excitatio...
Abelian and non-abelian anyons in integer quantum anomalous Hall effect and topological phase transitions via superconducting proximity effect
Abelian non-abelian anyons integer quantum anomalous Hall effect effect
2010/12/27
We study the quantum anomalous Hall effect described by a class of two-component Haldane models on square lattices. We show that the latter can be transformed into a pseudospin triplet p+ip-wave paire...
Figure "8" gravitational-wave antenna using a superconducting-core coaxial cable: Continuity equation and its superluminal consequences
General Relativity and Quantum Cosmology(gr-qc) Quantum Physics(quant-ph)
2010/11/9
A novel gravitational-wave antenna is proposed based on the prediction that supercurrents induced by gravitational waves in a superconductor that is bent into the shape of a figure "8" will couple eff...
Quantum Incompressibility of a Freely Falling Hydrogen Atom in a Circular Rydberg State, and a Gravitationally-Induced Charge Separation Effect in Superconducting Systems
Quantum Incompressibility Gravitationally-Induced Charge Separation Effect Superconducting Systems
2010/11/8
Freely falling point-like objects converge toward the center of the Earth. Hence the gravitational field of the Earth is inhomogeneous, and possesses a tidal component. The free fall of an extended qu...
Electromagnetically superconducting phase of QCD vacuum induced by strong magnetic field
Quantum Chromodynamics Strong Magnetic Fields Superconductivity Rho Condensation
2011/1/14
In this talk we discuss our recent suggestion that the QCD vacuum in a sufficiently strong magnetic field (stronger than 1016 Tesla) may undergo a spontaneous transition to an electromagnetically supe...

2010/12/20
In our Prague paper [1], we predicted that the Cooper pairs will respond to a gravitational (GR) wave di erently from the ions of the ionic lattice of a superconductor (SC), because there exists a glo...
Macroscopic quantum tunneling in multigap superconducting Josephson junctions: Escape rate enhancement via quantum fluctuations of Josephson-Leggett mode
Macroscopic quantum superconducting Josephson Escape rate enhancement Josephson-Leggett mode
2010/11/5
We theoretically study the macroscopic quantum tunneling (MQT) in a hetero Josephson junction formed by a conventional single-gap superconductor and a multi-gap one such as ${MgB}_{2}$ and iron-based...

We continuously measure the state of a superconducting quantum bit coupled to a microwave
readout cavity by using a fast, ultralow-noise parametric ampli er. This arrangement allows us to observe qua...
