Evidence of Andreev bound states as a hallmark of the FFLO phase in -(BEDT-TTF)Cu(NCS)

H. Mayaffre, S. Kramer, M. Horvatić +4

Superconductivity is a quantum phenomena arising, in its simplest form, from pairing of fermions with opposite spin into a state with zero net momentum. Whether superconductivity c…

Evidence for a small hole pocket in the Fermi surface of underdoped YBa2Cu3Oy

N. Doiron-Leyraud, S. Badoux, S. Rene de Cotret +13

The Fermi surface of a metal is the fundamental basis from which its properties can be understood. In underdoped cuprate superconductors, the Fermi surface undergoes a reconstructi…

Berry Phase in Cuprate Superconductors

N. Doiron-Leyraud, T. Szkopek, T. Pereg-Barnea +2

Geometrical Berry phase is recognized as having profound implications for the properties of electronic systems. Over the last decade, Berry phase has been essential to our understa…

Fermi-surface topology of the iron pnictide LaFeP

S. Blackburn, B. Prévost, M. Bartkowiak +12

We report on a comprehensive de Haas--van Alphen (dHvA) study of the iron pnictide LaFeP. Our extensive density-functional band-structure calculations can well explain the…

Incipient charge order observed by NMR in the normal state of YBa2Cu3Oy

T. Wu, H. Mayaffre, S. Krämer +6

The pseudogap regime of high-temperature cuprates harbours diverse manifestations of electronic ordering whose exact nature and universality remain debated. Here, we show that the…

Tunnel diode oscillator measurements of the upper critical magnetic field of FeTe0:5Se0:5

Alain Audouard, Loïc Drigo, Fabienne Duc +3

Temperature dependence of the upper critical magnetic field (Hc2) of single crystalline FeTe0.5Se0.5 (Tc = 14.5 K) have been determined by tunnel diode oscillator-based measurement…

Anomalous critical fields in quantum critical superconductors

C. Putzke, P. Walmsley, J. D. Fletcher +12

Fluctuations around an antiferromagnetic quantum critical point (QCP) are believed to lead to unconventional superconductivity and in some cases to high-temperature superconductivi…

Critical doping for the onset of a two-band superconducting ground state in SrTiO

Xiao Lin, German Bridoux, Adrien Gourgout +5

In doped SrTiO superconductivity persists down to an exceptionally low concentration of mobile electrons. This restricts the relevant energy window and possible pairing scena…
