Transition between critical antiferromagnetic phases in the - spin chain
Adam J. McRoberts, Chris Hooley, A. G. Green
The - spin chain is one of the canonical models of quantum magnetism, and has long been known to host a critical antiferromagnetic phase with power-law decay of spin corr…
Ballistic conductance with and without disorder in a boundary-driven XXZ spin chain
Adam J. McRoberts, Roderich Moessner
Motivated by recent experiments on Google's sycamore NISQ platform on the spin transport resulting from a non-unitary periodic boundary drive of an XXZ chain, we study a classical…
A Generalised Haldane Map from the Matrix Product State Path Integral to the Critical Theory of the - Chain
F. Azad, Adam J. McRoberts, Chris Hooley +1
We study the - spin- chain using a path integral constructed over matrix product states (MPS). By virtue of its non-trivial entanglement structure, the MPS ansatz ca…
Parametrically long lifetime of superdiffusion in non-integrable spin chains
Adam J. McRoberts, Roderich Moessner
Superdiffusion is surprisingly easily observed even in systems without the integrability underpinning this phenomenon. Indeed, the classical Heisenberg chain -- one of the simplest…
