Rotationally resolved photoelectron spectra from vibrational autoionization of individual rotational levels of the nlR v 1, 11 n 15, 0 lR 3 Rydberg states of NO are measured by combining two-color double-resonance excitation via the NO A 2 v i 1, Ni 19 state with time-of-flight photoelectron spectroscopy. The photoelectron spectra show that both even-l and odd-l continuum partial waves are gene...

Single electron tunneling into small superconducting islands is sensitive to the gap energy of the excitations created in the process and, hence, depends on the electron number parity. At low temperature the properties of the system are 2e-periodic in the applied gate voltage, turning e-periodic at higher temperature. We evaluate the tunneling rates and determine the probabilities for the even ...

Cotunneling into Kondo systems, where an electron enters an f -electron material via a cotunneling process through the local-moment orbital, has been proposed to explain the characteristic line shapes observed in scanning-tunneling-spectroscopy (STS) experiments. Here we extend the theory of electron cotunneling to Kondo-lattice systems in which the bulk hybridization between conduction and f e...

The bremsstrahlung flux-averaged cross sections for the photoneutron reactions $^{\text{93}}$Nb($\gamma $,xn;x=1-5)$^{\text{(93-x)m,g}}$Nb were measured in range of boundary energies $\gamma $-quanta $E_{\gamma \text{max}}$=33-93 MeV with a step $\Delta E_{\gamma \text{max}}\approx $ 2 MeV. isomeric ratios average cross-sections products $^{\text{93}}$Nb ($\gamma ,4n)$^{\text{89m,g}}$Nb and $,5...

A new class of singlet superconductors with a gap function ∆(k, ωn) which is odd in both momentum and Matsubara frequency is considered. Some of the physical properties of this superconductivity are discussed and it is argued that: i) the electron-phonon interaction can produce this kind of pairing, ii) in many cases there is no gap in the quasiparticle spectrum, iii) these superconductors will...

Chiral Majorana hinge modes are characteristic of a second-order topological superconductor in three dimensions. Here we systematically study pairing symmetry the point group D_{2h}, and find that leading channels can be s-, d-, s+id-wave Dirac materials. Except for odd-parity s-wave superconductivity, is topologically nontrivial possesses surface modes. The chiral characterized by winding numb...
