The Van Hove singularity (VHS) provides a paradigm for the study of the role of peaks in the density of states (dos) on electronic properties. More importantly, it appears to play a major role in the physics of the high-Tc superconductors, particularly since recent photoemission studies have found t...

The observed increase of superconducting transition temperature (T(c)) with the number of copper oxide planes continues in the four-[CuO(2)](-2) layer (single TI layer) oxide superconductor, which has been prepared with > 80% purity and was magnetically aligned for crystallographic identification. A...

Two circular chromosomes are a defining feature of the bacterial family Vibrionaceae, including the pathogen Vibrio cholerae, with rare reports of isolates with a single, fused chromosome. Here, we use long-read sequencing to analyse 467 V. cholerae O1 isolates from 47 cholera patients and household...

We have initially aligned polycrystalline EuBa2Cu3O7-δ (Eu-123) Superconductor using a magnetic force and a mechanical force simultaneously to fabricate biaxially aligned rare earth (RE) substituted Eu-123 thick films as homo-substrates for growth of epitaxial YBa2Cu3O7-δ superconductor thin films. ...

Abstract Two circular chromosomes are a defining feature of the family Vibrionaceae , including the pathogen Vibrio cholerae , with rare reports of isolates with a single, fused chromosome. Here we report chromosome fusions in clinical V. cholerae O1 isolates, including several independent fusion ev...

The smooth evolution of the tunneling gap of Bi2Sr2CaCu2O8 with doping from a pseudogap state in the underdoped cuprates to a superconducting state at optimal and overdoping reflects an underlying SO(6) instability structure of the (π, 0) saddle points. The pseudogap is probably not associated with ...

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 Coulomb repulsion and coherency strains. We find evidence for a possible stripe disordering transition, at a temperature bel...
