Universal V-shaped temperature-pressure phase diagram in the iron-based superconductors KFe2As2, RbFe2As2, and CsFe2As2

F. F. Tafti, A. Ouellet, A. Juneau-Fecteau +7

We report a sudden reversal in the pressure dependence of Tc in the iron-based superconductor RbFe2As2, at a critical pressure Pc = 11 kbar. Combined with our prior results on KFe2…

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…

Isotropic multi-gap superconductivity in BaFe1.9Pt0.1As2 from thermal transport and spectroscopic measurements

Steven Ziemak, K. Kirshenbaum, S. R. Saha +11

Thermal conductivity, point contact spectroscopy, angle-resolved photoemission and Raman spectroscopy measurements were performed on BaFe1.9Pt0.1As2 single crystals obtained from t…

Chiral d-wave superconductivity on the honeycomb lattice close to the Mott state

Annica M. Black-Schaffer, Wei Wu, Karyn Le Hur

We study superconductivity on the honeycomb lattice close to the Mott state at half-filling. Due to the sixfold lattice symmetry and disjoint Fermi surfaces at opposite momenta, we…

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…

Competition between superconductivity and magnetic/nematic order as a source of anisotropic superconducting gap in underdoped BaKFeAs

H. Kim, M. A. Tanatar, W. E. Straszheim +8

The in-plane London penetration depth, , was measured using a tunnel diode resonator technique in single crystals of BaKFeAs with doping levels …
