Generation of Large Moments in a Spin-1 Chain with Random Antiferromagnetic Couplings
Kun Yang, R. N. Bhatt
We study the spin-1 chain with nearest neighbor couplings that are rotationally invariant, but include both Heisenberg and biquadratic exchange, with random strengths. We demonstra…

Floating of Extended States and Localization Transition in a Weak Magnetic Field
Kun Yang, R. N. Bhatt
We report results of a numerical study of non-interacting electrons moving in a random potential in two dimensions in the presence of a weak perpendicular magnetic field. We study…

Random Bonds and Topological Stability in Gapped Quantum Spin Chains
R. A. Hyman, Kun Yang, R. N. Bhatt +1
We study the effects of random bonds on spin chains that have an excitation gap in the absence of randomness. The dimerized spin-1/2 chain is our principal example. Using an asympt…
