Efficient learning of ground and thermal states within phases of matter

Autor: Cambyse Rouzé, Daniel Stilck França, Emilio Onorati, James D. Watson

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-8 (2024)

Abstract We consider two related tasks: (a) estimating a parameterisation of a given Gibbs state and expectation values of Lipschitz observables on this state; (b) learning the expectation values of local observables within a thermal or quantum phase

Uncomputably complex renormalisation group flows

Autor: James D. Watson, Emilio Onorati, Toby S. Cubitt

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-8 (2022)

Renormalisation group methods serve for finding analytic solutions, critical points and computing phase diagrams of many-body systems. Here the authors demonstrate that renormalisation group schemes can be constructed for undecidable many-body system

Uncomputability of phase diagrams

Autor: Johannes Bausch, Toby S. Cubitt, James D. Watson

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-8 (2021)

Phase diagrams describe how a system changes phenomenologically as an external parameter, such as a magnetic field strength, is varied. Here, the authors prove that in general such a phase diagram is uncomputable, by explicitly constructing a one-par

Crystal structure of 1-heptafluorotolyl-closo-1,2-dicarbadodecaborane

Autor: James D. Watson, Amanda Benton, Hugo Tricas, Georgina M. Rosair, Alan J. Welch

Publikováno v: Acta Crystallographica Section E: Crystallographic Communications, Vol 75, Iss 4, Pp 512-515 (2019)

The molecular structure of the title compound 1-(2′,3′,5′,6′-tetrafluoro-4′-trifluoromethylphenyl)-closo-1,2-dicarbadodecaborane, C9H11B10F7, features an intramolecular ortho-F...H2 hydrogen bond [2.11 (2) Å], which is responsible for an o
