High-Temperature Criticality in Strongly Constrained Quantum Systems
Claudio Castelnovo, Claudio Chamon, Christopher Mudry +2
The exotic nature of many strongly correlated materials at reasonably high temperatures, for instance cuprate superconductors in their normal state, has lead to the suggestion that…
Disorder-induced critical phenomena--new universality classes in Anderson localization
P. W. Brouwer, A. Furusaki, C. Mudry +1
The Anderson metal-insulator transition is a continuous phase transition driven by disorder. It remains a challenging problem to theoretically determine universal critical properti…
Theory for Inelastic Neutron Scattering in Orthorhombic High-Tc Superconductors
Andreas P. Schnyder, Dirk Manske, Christopher Mudry +1
Using a Fermi-liquid-based theory we calculate the in-plane anisotropy of the spin susceptibility for hole-doped high-T_c cuprates. Employing the two-dimensional one-band Hubbard m…
Universal Scaling Relations in Strongly Anisotropic Materials
M. B. Hastings, C. Mudry
We consider the critical temperature in strongly anisotropic antiferromagnetic materials, with weak coupling between stacked planes, in order to determine the interplane coupling c…
From quantum mechanics to classical statistical physics: generalized Rokhsar-Kivelson Hamiltonians and the "Stochastic Matrix Form" decomposition
Claudio Castelnovo, Claudio Chamon, Christopher Mudry +1
Quantum Hamiltonians that are fine-tuned to their so-called Rokhsar-Kivelson (RK) points, first presented in the context of quantum dimer models, are defined by their representatio…
