# Self-consistent theory of many-body localisation in a quantum spin chain with long-range interactions

@article{Roy2019SelfconsistentTO, title={Self-consistent theory of many-body localisation in a quantum spin chain with long-range interactions}, author={Sthitadhi Roy and David E. Logan}, journal={SciPost Physics}, year={2019} }

Many-body localisation is studied in a disordered quantum spin-1/2
chain with long-ranged power-law interactions, and distinct power-law
exponents for interactions between longitudinal and transverse spin
components. Using a self-consistent mean-field theory centring on the
local propagator in Fock space and its associated self-energy, a
localisation phase diagram is obtained as a function of the power-law
exponents and the disorder strength of the random fields acting on
longitudinal spin…
