High temperature superconductivity in sulfur and selenium hydrides at high pressure [PDF]

open access: yesEuropean Physical Journal B : Condensed Matter Physics, 2015
Due to its low atomic mass, hydrogen is the most promising element to search for high-temperature phononic superconductors. However, metallic phases of hydrogen are only expected at extreme pressures (400 GPa or higher).

Magnetic field induced charge order in cuprate superconductors: an explanation by spin-vortex-induced loop currents [PDF]

open access: yesJournal of Physics: Conference Series, 2018
We present a possible explanation for a recently observed magnetic field induced charge order in cuprate superconductors (Edkins et al. arXiv:1802.04673 [cond-mat.supr-con]).

Superconductivity without Fe or Ni in the phosphides BaIr2P2 and BaRh2P2 [PDF]

open access: yes, 2009
Heat capacity, resistivity, and magnetic susceptibility measurements confirm bulk superconductivity in single crystals of BaIr$_2$P$_2$ (T$_c$=2.1K) and BaRh$_2$P$_2$ (T$_c$ = 1.0 K). These compounds form in the ThCr$_2$Si$_2$ (122) structure so they are

Proximity induced superconductivity by Bi in topological $Bi_2Te_2Se$ and $Bi_2Se_3$ films: Evidence for a robust zero energy bound state possibly due to Majorana Fermions

open access: yes, 2011
Point contact conductance measurements on topological $Bi_2Te_2Se$ and $Bi_2Se_3$ films reveal a signature of superconductivity below 2-3 K. In particular, critical current dips and a robust zero bias conductance peak are observed.

Isotope effect on the E2g phonon and mesoscopic phase separation near the electronic topological transition in Mg1-xAlxB2

open access: yes, 2009
We report the boron isotope effect on the E2g phonon mode by micro-Raman spectroscopy on the ternary Mg1-xAlxB2 system, synthesized with pure isotopes 10B and 11B.

The novel metallic states of the cuprates: Fermi liquids with topological order, and strange metals

open access: yes, 2016
This article is based on a talk by S.S. at the Nambu Memorial Symposium at the University of Chicago. We review ideas on the nature of the metallic states of the hole-doped cuprate high temperature superconductors, with an emphasis on the connections ...

High-$T_c$ mechanism through analysis of diverging effective mass for YaBa$_2$Cu$_3$O$_{6+x}$ and pairing symmetry in cuprate superconductors

open access: yes, 2017
In order to clarify the high-$T_c$ mechanism in inhomogeneous cuprate layer superconductors, we deduce and find the correlation strength not revealed before, contributing to the formation of the Cooper pair and the 2-D density of state, and demonstrate ...

Topological phase transitions in multi-component superconductors

open access: yes, 2017
We study the phase transition between a trivial and a time-reversal-invariant topological superconductor in a single-band system. By analyzing the interplay of symmetry, topology and energetics, we show that for a generic normal state band structure, the
