Filamentary superconductivity of resistively-switched strontium titanate
K. Szot, C. Rodenbücher, K. Rogacki +7
SrTiO, although a wide gap insulator, has long been known to become metallic and superconducting at extremely low doping levels. This has given rise to questions concerning the…
Multi-Band Superconductivity and the Steep Band -- Flat Band Scenario
Annette Bussmann-Holder, Hugo Keller, Arndt Simon +1
The basic features of multi-band superconductivity and its implications are derived. In particular, it is shown that enhancements of the superconducting transition temperature take…
The road map toward room temperature superconductivity: manipulating different pairing channels in systems composed of multiple electronic components
Annette Bussmann-Holder, Jurgen Kohler, Arndt Simon +3
While it is known that the amplification of the superconducting critical temperature Tc is possible in a system of multiple electronic components in comparison with a single compon…
High temperature superconductivity in sulfur hydride under ultrahigh pressure: A complex superconducting phase beyond conventional BCS
Annette Bussmann-Holder, Jurgen Kohler, M. -H. Whangbo +2
The recent report of superconductivity under high pressure at the record transition temperature of Tc=203K in sulfur hydride has been identified as conventional in view of the obse…
Unconventional dynamical covalency driven superconductivity in Nb doped SrTiO3
A. Bussmann-Holder, A. R. Bishop, A. Simon
Nb doped SrTiO3, the first discovered two-gap superconductor, is shown to be the most unconventional one of the known multiband superconductors, since the smaller of the two superc…
Superconductivity in Fe and As based compounds: a bridge between MgB2 and cuprates
A. Bussmann-Holder, A. Simon, H. Keller +1
By interpreting various experimental data for the new high temperature FeAs type superconductors in terms of lattice mediated multi gap superconductivity, it is shown that these sy…
Identifying the pairing mechanism in Fe-As based superconductors: gaps and isotope effects
A. Bussmann-Holder, A. Simon, H. Keller +1
The temperature dependencies of the coupled superconducting gaps, observed in Fe-As based superconducting compounds is calculated and a universal temperature scaling observed which…
Polaron Coherence as Origin of the Pseudogap Phase in High Temperature Superconducting Cuprates
A. Bussmann-Holder, H. Keller, A. R. Bishop +2
Within a two component approach to high Tc copper oxides including polaronic couplings, we identify the pseudogap phase as the onset of polaron ordering. This ordering persists in…
Carbon Based Superconductors
Reinhard K. Kremer, Jun Sung Kim, Arndt Simon
We review the characteristics of some carbon based novel superconductors which emerged in the past two decades since the discovery of superconductivity in the high-T_c oxocuprates.…
Real and marginal isotope effects in cuprate superconductors
A. R. Bishop, A. Bussmann-Holder, O. V. Dolgov +8
We critically review recent and earlier results on isotope effects in cuprate superconductors and emphasize that the sample preparation and the isotope exchange and back exchange a…
Theory of Dynamic Stripe Induced Superconductivity
Annette Bussmann-Holder, K. Alex Muller, Roman Micnas +4
Since the recently reported giant isotope effect on T* [1] could be consistently explained within an anharmonic spin-charge-phonon interaction model, we consider here the role play…
