Angle Resolved Photemission Experiments to look for Time-reversal Violation in Cuprates
J. C. Campuzano, A. Kaminski, C. M. Varma
The recent experiments reported by Borisenko et al. (cond-mat/0305179 v2), are examined in light of the conditions to be satisfied in the search for time-reversal violation by circ…
Reply to Comment on: "Spontaneous breaking of time-reversal symmetry in the pseudogap state of a high-Tc superconductor"
A. Kaminski, S. Rosenkranz, H. M. Fretwell +8
In a recent comment [1], Armitage and Hu have suggested that our experiment observing dichroism in angle resolved photoemission (ARPES) [2] could not be conclusively interpreted as…
Hall effect in the marginal Fermi liquid regime of high-Tc superconductors
Elihu Abrahams, C. M. Varma
The detailed derivation of a theory for transport in quasi-two-dimensional metals, with small-angle elastic scattering and angle-independent inelastic scattering is presented. The…
Electronic-vibrational coupling in single-molecule devices
Vivek Aji, J. E. Moore, C. M. Varma
Experiments studying vibrational effects on electronic transport through single molecules have observed several seemingly inconsistent behaviors, ranging from up to 30 harmonics of…
Specific heat at the transition in a superconductor with fluctuating magnetic moments
Simon Kos, Ivar Martin, C. M. Varma
In the heavy-fermion materials CeCoIn and UBe, the superconducting order parameter is coupled to flucutating magnetization of the uncompensated part of the localized …
