Experimental signatures of time-reversal-violating superconductors
We discuss some experimental signatures associated with the topological structures of unconventional superconductor order parameters of form dx2−y2 + ix, where x=s, px± py, or dxy. Specifically, we study the topological surface states on the s110d and equivalent surfaces of such superconductors which are observable in Andreev tunneling experiments, as well as evaluate the magnetic flux trapped ...
متن کاملThermoelectric Signatures of Time-Reversal Symmetry Breaking States in Multiband Superconductors.
We show that superconductors with broken time-reversal symmetry have very specific magnetic and electric responses to inhomogeneous heating. A local heating of such superconductors induces a magnetic field with a profile that is sensitive to the presence of domain walls and crystalline anisotropy of superconducting states. A nonstationary heating process produces an electric field and a charge ...
متن کاملTime - reversal - violating Schiff moment of 199 Hg
We calculate the Schiff moment of the nucleus 199Hg, created by πNN vertices that are odd under parity (P) and time-reversal (T). Our approach, formulated in diagrammatic perturbation theory with important core-polarization diagrams summed to all orders, gives a close approximation to the expectation value of the Schiff operator in the odd-A Hartree-Fock-Bogoliubov ground state generated by a S...
متن کاملLimits of Time-Reversal Violating Interaction from Compound Nuclear Experiments
Mean square matrix elements of the time reversal invariance violating (TRIV) interaction between the compound nuclear states are calculated within the statistical model, using the explicit form of the TRIV interaction via the ρmeson exchange. From the comparison of the calculated values with the data known for p+27Al ⇔24 Mg+α reaction, and for γ-correlation measurements in 113Cd(n, γ)114Cd proc...
متن کامل0 Parity and time reversal violating nuclear polarizability
We propose a nuclear mechanism which can induce an atomic electric dipole moment (EDM). Parity and time reversal violating (P, T-odd) nuclear forces generate a mixed P, T-odd nuclear polarizability β ik (defined by an energy shift U = −β ik E i H k , E is electric field and H magnetic field). The interaction of atomic electrons with β ik produces an atomic EDM. We performed an analytical calcul...
