Scalable Spin Squeezing from Finite Temperature Easy-plane Magnetism
Maxwell Block, Bingtian Ye, Brenden Roberts +7
Spin squeezing is a form of entanglement that reshapes the quantum projection noise to improve measurement precision. Here, we provide numerical and analytic evidence for the follo…
Infinite randomness with continuously varying critical exponents in the random XYZ spin chain
Brenden Roberts, Olexei I. Motrunich
We study the antiferromagnetic XYZ spin chain with quenched bond randomness, focusing on a critical line between localized Ising magnetic phases. A previous calculation using the s…
One-dimensional model for deconfined criticality with symmetry
Brenden Roberts, Shenghan Jiang, Olexei I. Motrunich
We continue recent efforts to discover examples of deconfined quantum criticality in one-dimensional models. In this work we investigate the transition between a fer…
Deconfined quantum critical point in one dimension
Brenden Roberts, Shenghan Jiang, Olexei I. Motrunich
We perform a numerical study of a spin-1/2 model with symmetry in one dimension which demonstrates an interesting similarity to the physics of tw…
Implementation of rigorous renormalization group method for ground space and low-energy states of local Hamiltonians
Brenden Roberts, Thomas Vidick, Olexei I. Motrunich
The practical success of polynomial-time tensor network methods for computing ground states of certain quantum local Hamiltonians has recently been given a sound theoretical basis…
Majorana Fermions in Chiral Topological Ferromagnetic Nanowires
Eugene Dumitrescu, Brenden Roberts, Sumanta Tewari +2
Motivated by a recent experiment in which zero-bias peaks have been observed in scanning tunneling microscopy (STM) experiments performed on chains of magnetic atoms on a supercond…
