Properties and application of SO(3) Majorana representation of spin: Equivalence with Jordan-Wigner transformation and exact gauge theories for spin models

J Fu - Physical Review B, 2018 - APS
We explore the properties of the SO (3) Majorana representation of spin. Based on its
nonlocal nature, it is shown that there is an equivalence between the SO (3) Majorana …

Quantum computation from fermionic anyons on a 1D lattice

ADC Tosta, DJ Brod, EF Galvão - arXiv preprint arXiv:1812.06807, 2018 - arxiv.org
Fermionic linear optics corresponds to the dynamics of free fermions, and is known to be
efficiently simulable classically. We define fermionic anyon models by deforming the …

Gaussian statistics as an emergent symmetry of the stochastic Burgers equation

E Rodriguez-Fernandez, R Cuerno - arXiv preprint arXiv:1809.02158, 2018 - arxiv.org
Symmetries play a conspicuous role in the large-scale behavior of critical systems. While in
equilibrium they allow to classify asymptotics into different universality classes, out of …
