Quantum phase transition in spin systems studied through entanglement estimators
Andrea Fubini, Stephan Haas, Tommaso Roscilde +2
Entanglement represents a pure quantum effect involving two or more particles. Spin systems are good candidates for studying this effect and its relation with other collective phen…

Resonance Impurity Scattering in PrOsSb
David Parker, Stephan Haas. Kazumi Maki
We study the effect of impurity scattering in the unitarity limit on the A and B phase superconductivity in PrOs4Sb12. We take the triplet superconducting order parameters and the…
