Crossover from Poisson to Wigner-Dyson Level Statistics in Spin Chains with Integrability Breaking
D. A. Rabson, B. N. Narozhny, A. J. Millis
We study numerically the evolution of energy-level statistics as an integrability-breaking term is added to the XXZ Hamiltonian. For finite-length chains, physical properties exhib…
Interaction corrections at intermediate temperatures: I. Longitudinal conductivity and kinetic equation
Gabor Zala, B. N. Narozhny, I. L. Aleiner
It is well known that electron-electron interaction in disordered systems leads to logarithmically divergent Altshuler-Aronov corrections to conductivity at low temperatures ($Tτ\l…
Effect of Time Reversal Symmetry Breaking on the Density of States in Small Superconducting Grains
I. S. Beloborodov, B. N. Narozhny, I. L. Aleiner
We show that in ultra-small superconducting grains any concentration of magnetic impurities or infinitely small orbital effect of magnetic field leads to destruction of the hard ga…
Mesoscopic fluctuations of the Coulomb drag
B. N. Narozhny, I. L. Aleiner
We consider mesoscopic fluctuations of the Coulomb drag coefficient in the system of two separated two-dimensional electron gases. It is shown that at low temperatures sample…
Low temperature transport in the XXZ model
B. N. Narozhny, A. J. Millis, N. Andrei
We present evidence suggesting that spin transport in the gapless phase of the S=1/2 XXZ model is ballistic rather than diffusive. We map the model onto a spinless fermion model wh…
On the Problem of Spin Diffusion in 1D Antiferromagnets
Boris Narozhny
We study the problem of spin diffusion in magnetic systems without long-range order. We discuss the example of the 1D spin chain. For the system described by the Heisenberg Hamilto…
