EB Mixing in Tviolating Superconductors
, 2008
"... We analyze time reversal violating processes of the pwave superconductor. The LandauGinzuburg effective action has an induced Tviolating term of electromagnetic potentials which resembles the ChernSimons term and causes a mixing between the electric field and the magnetic field. Several Tviolat ..."

Tunneling Gap as Evidence for TimeReversal Symmetry Breaking at Surfaces of HighTemperature Superconductors
, 1994
"... It is argued that recent Josephson junction and pointcontact tunneling experiments, interpreted as intended by their authors, indicate that timereversal symmetry breaking occurs at surfaces of cuprate superconductors. The variation among experiments and the failure of previous searches to find Tv ..."

RENORMALIZATION GROUP ANALYSIS OF QUANTUM CRITICAL POINTS IN dWAVE SUPERCONDUCTORS
, 2008
"... We describe a search for renormalization group fixed points which control a secondorder quantum phase transition between a d x 2 −y 2 superconductor and some other superconducting ground state. Only a few candidate fixed points are found. In the finite temperature (T) quantumcritical region of som ..."

Second Law Violation By MagnetoCaloric Effect Adiabatic Phase Transition of Type I Superconductor Particles
"... Abstract: The nature of the thermodynamic behavior of Type I superconductor particles, having a cross section less than the GinzburgLandau temperature dependent coherence length, ξ(T), is discussed for magnetic field induced adiabatic phase transitions from the superconductive state to the normal s ..."

Vortex in Chiral Superconducting State
, 1999
"... We have investigated the vortex in chiral superconductors, especially in pwave case. In chiral superconductors the Cooper pair has orbital angular momentum hence U(1), parity (P) and time reversal symmetry (T) are broken simultaneously. We have found that the vortex has fractional charge and fracti ..."

of the chiral pwave (px + ipywave) superconductivity in Sr2RuO4. 2 Chiral dwave (d x 2 −y 2 + idxywave) superconductivity has been proposed in HighTc superconductors. 3 It is important to investigate P and Tviolating phenomena to probe the chiral superconductivity. In the present paper,
Magnetic Properties of HTSC with a Weak Interlayer Coupling.
, 2008
"... Magnetic properties of layered high temperature superconductors with a weak interlayer coupling in the region of the critical fluctuations are investigated in the framework of the Ginzburg–Landau approach. The sample magnetization is calculated within a perturbative approach to the second order in t ..."

low and to disappearance of the magnetization crossing point. 1 Introduction. Scaling properties of layered high temperature superconductors (HTSC) around the mean–filed transition line Hc2(T) has been under intensive experimental [1, 2] and theoretical [3, 4, 5, 6, 7, 8, 9] study during the last
FieldTheoretical Analysis of Anyonic Superconductivity
 Int. Jour. Mod. Phys. A
, 1991
"... We derive several results pertaining to anyonic superconductivity BS described by a ChernSimons field theory. (1) The renormalized ChernSimons term at finite density is shown to vanish when the renormalized coefficient at zero density takes values Nea/2r. This is the field theoretical requirement ..."

This result is shown to hold to all orders in perturbatiori theory by generalizing a nonrenormalization theorem
c © TÜB_ITAK Mesoscopic dWave Qubits: Can HighTc Cuprates Play a Role in Quantum Computing?
"... Due to nontrivial orbital pairing symmetry, surfaces and interfaces of highTc superconductors support states which violate timereversal (T) symmetry. Such naturally degenerate states, useful as working states of a qubit, are standard for atomic or molecularsize qubit prototypes (e.g. based on ..."

Strongly first order electroweak phase transition induced by primordial hypermagnetic
, 1998
"... We consider the effect of the presence of a hypermagnetic field at the electroweak phase transition. Screening of the Zcomponent inside a bubble of the broken phase delays the phase transition and makes it stronger first order. We show that the sphaleron constraint can be evaded for mH up to 100 Ge ..."
