The first Hochschild cohomology group of a schurian cluster-tilted algebra
Ibrahim Assem, Maria Julia Redondo
Given a cluster-tilted algebra B we study its first Hochschild cohomology group HH^1(B) with coefficients in the B-B-bimodule B. We find several consequences when B is representati…
Ambient-pressure bulk superconductivity deep in the magnetic state of CeRhIn5
Johnpierre Paglione, P. -C. Ho, M. B. Maple +4
Specific heat, magnetic susceptibility and electrical transport measurements were performed at ambient pressure on high-quality single crystal specimens of CeRhIn5 down to ultra-lo…
Reply to comment by Y. Ando on "Onset of Boson Mode at the Superconducting Critical Point of Underdoped YBaCuO" by N. Doiron-Leyraud et al
Nicolas Doiron-Leyraud, Louis Taillefer
In a recent Comment [arXiv:0711.4654], Y. Ando raises two valid issues in relation to our low-temperature heat transport study of YBaCuO across the insulator-to-superco…
Complex microwave conductivity of PrCeCuO thin films using a cavity perturbation method
Guillaume Cote, Mario Poirier, Patrick Fournier
We report a study of the microwave conductivity of electron-doped PrCeCuO superconducting thin films using a cavity perturbation technique. The relative f…
Conditions for magnetically induced singlet d-wave superconductivity on the square lattice
S. R. Hassan, B. Davoudi, B. Kyung +1
It is expected that at weak to intermediate coupling, d-wave superconductivity can be induced by antiferromagnetic fluctuations. However, one needs to clarify the role of Fermi sur…
de Haas-van Alphen oscillations in the underdoped cuprate YBaCuO
C. Jaudet, D. Vignolles, A. Audouard +11
The de Haas-van Alphen effect was observed in the underdoped cuprate YBaCuO via a torque technique in pulsed magnetic fields up to 59 T. Above an irreversibility fi…
