Stripe Disordering Transition
R. S. Markiewicz, M. T. Vaughn
We have recently begun Monte Carlo simulations of the dynamics of stripe phases in the cuprates. A simple model of spinodal decomposition of the holes allows us to incorporate Coul…
SO(6)-Generalized Pseudogap Model of the Cuprates
R. S. Markiewicz, C. Kusko, M. T. Vaughn
The smooth evolution of the tunneling gap of Bi_2Sr_2CaCu_2O_8 with doping from a pseudogap state in the underdoped cuprates to a superconducting state at optimal and overdoping re…
Higher Symmetries in Condensed Matter Physics
R. S. Markiewicz, M. T. Vaughn
We discuss some applications of higher symmetry groups to condensed matter systems. We give special attention to the groups SO(n) (n = 4, 5, 6, 8) in the two-dimensional Hubbard mo…
Tunneling and Photoemission in an SO(6) Superconductor
R. S. Markiewicz, C. Kusko, M. T. Vaughn
Combining the results of tunneling, photoemission and thermodynamic studies, the pseudogap is unambiguously demonstrated to be caused by Van Hove nesting: a splitting of the densit…
The Spectrum-Generating Algebra of the Van Hove Scenario is SO(8)
R. S. Markiewicz, M. T. Vaughn
The various nesting and pairing instabilities of the generalized Van Hove scenario can be classified via an SO(8) spectrum-generating algebra. An SO(6) subgroup is an approximate s…
Stripes, pseudogaps, and SO(6) in the cuprate superconductors
R. S. Markiewicz, M. T. Vaughn
We briefly summarize two related calculations. First, we demonstrate that the instabilities (either nesting or pairing) associated with the high-T_c cuprates can be described by an…
