Emergence of coherence in the charge-density wave state of 2H-NbSe
U. Chatterjee, J. Zhao, M. Iavarone +15
A charge-density wave (CDW) state has a broken symmetry described by a complex order parameter with an amplitude and a phase. The conventional view, based on clean, weak-coupling s…
High Temperature Superconductivity - Magnetic Mechanisms
M. R. Norman
A brief history is offered concerning the relation of magnetism to superconductivity, and the possibility that magnetic correlations are responsible for certain types of supercondu…
Absence of Persistent Magnetic Oscillations in Type-II Superconductors
M. R. Norman, A. H. MacDonald
We report on a numerical study intended to examine the possibility that magnetic oscillations persist in type II superconductors beyond the point where the pairing self-energy exce…
Contrasting Dynamic Spin Susceptibility Models and their Relation to High Temperature Superconductivity
H. -B. Schuttler, M. R. Norman
We compare the normal-state resistivities and the critical temperatures for superconducting pairing due to antiferromagnetic (AF) spin fluctuation exchange…
Calculation of Effective Coulomb Interaction for , , and
M. R. Norman
In this paper, the Slater integrals for a screened Coulomb interaction of the the Yukawa form are calculated and by fitting the Thomas-Fermi wavevector, good agreement is obtained…
Phenomenological BCS theory of the high- cuprates
R. Fehrenbacher, M. R. Norman
A BCS model characterized by a phenomenological pair potential with on-site (), nearest (), and next nearest () neighbour coupling constants, and an empirical quasip…
Magnetic Oscillations and Quasiparticle Band Structure in the Mixed State of Type-II Superconductors
M. R. Norman, A. H. MacDonald, H. Akera
We consider magnetic oscillations due to Landau quantization in the mixed state of type-II superconductors. Our work is based on a previously developed formalism which allows the m…
Effect of Structure on the Electronic Density of States of Doped Lanthanum Cuprate
M. R. Norman, G. J. McMullan, D. L. Novikov +1
We present a series of detailed band calculations on the various structural phases of doped lanthanum cuprate: HTT, LTO, and LTT. The LTO distortion is shown to have little effect…
Effect of Matrix Elements on the Pairing Kernel in Exchange Mediated Superconductors
M. R. Norman
A method is derived for calculating the pairing kernel in exchange mediated superconductors including matrix element effects. Various models for the interaction vertex are consider…
