Breakdown of One-Paramater Scaling in Quantum Critical Scenarios for the High-Temperature Copper-oxide Superconductors
Philip Phillips, Claudio Chamon
We show that if the excitations which become gapless at a quantum critical point also carry the electrical current, then a resistivity linear in temperature, as is observed in the…
Heterogeneous slow dynamics in a two dimensional doped classical antiferromagnet
Malcolm P. Kennett, Claudio Chamon, Leticia F. Cugliandolo
We introduce a lattice model for a classical doped two dimensional antiferromagnet which has no quenched disorder, yet displays slow dynamics similar to those observed in supercool…
Quantum three-coloring dimer model and the disruptive effect of quantum glassiness on its line of critical points
Claudio Castelnovo, Claudio Chamon, Christopher Mudry +2
We construct a quantum extension of the (classical) three-coloring model introduced by Baxter [J.Math.Phys.11, 784 (1970)] for which the ground state can be computed exactly along…
Quantum Glassiness
Claudio Chamon
Describing matter at near absolute zero temperature requires understanding a system's quantum ground state and the low energy excitations around it, the quasiparticles, which are t…
Excitations and Quantum Fluctuations in Site Diluted Two-Dimensional Antiferromagnets
Eduardo R. Mucciolo, A. H. Castro Neto, C. Chamon
We study the effect of site dilution and quantum fluctuations in an antiferromagnetic spin system on a square lattice within the linear spin-wave approximation. By performing numer…
Out-of-equilibrium dynamical fluctuations in glassy systems
C. Chamon, P. Charbonneau, L. F. Cugliandolo +2
In this paper we extend the earlier treatment of out-of-equilibrium mesoscopic fluctuations in glassy systems in several significant ways. First, via extensive simulations, we demo…
