Infinite-randomness quantum Ising critical fixed points
We examine the ground state of the random quantum Ising model in a transverse field using a generalization of the Ma-Dasgupta-Hu renormalization group ~RG! scheme. For spatial dimensionality d52, we find that at strong randomness the RG flow for the quantum critical point is towards an infinite-randomness fixed point, as in one dimension. This is consistent with the results of a recent quantum ...
متن کاملInfinite-randomness fixed points for chains of non-Abelian quasiparticles.
One-dimensional chains of non-Abelian quasiparticles described by SU(2)k Chern-Simons-Witten theory can enter random singlet phases analogous to that of a random chain of ordinary spin-1/2 particles (corresponding to k-->infinity). For k=2 this phase provides a random singlet description of the infinite-randomness fixed point of the critical transverse field Ising model. The entanglement entrop...
متن کاملEntanglement entropy at infinite-randomness fixed points in higher dimensions.
The entanglement entropy of the two-dimensional random transverse Ising model is studied with a numerical implementation of the strong-disorder renormalization group. The asymptotic behavior of the entropy per surface area diverges at, and only at, the quantum phase transition that is governed by an infinite-randomness fixed point. Here we identify a double-logarithmic multiplicative correction...
متن کاملFixed Points on Partial Randomness
Algorithmic information theory (AIT, for short) is a theory of program-size and algorithmic randomness. One of the primary concepts of AIT is the Kolmogorov complexity K(s) of a finite binary string s, which is defined as the length of the shortest binary program for a universal decoding algorithm to output s. In this paper, we report on a quite new type of fixed point in computer science, call...
متن کاملc-theorem violation for effective central charge of infinite-randomness fixed points
Topological insulators supporting non-Abelian anyonic excitations are in the center of attention as candidates for topological quantum computation. In this paper, we analyze the ground-state properties of disordered non-Abelian anyonic chains. The resemblance of fusion rules of non-Abelian anyons and real-space decimation strongly suggests that disordered chains of such anyons generically exhib...
