Statistical-mechanics of a three-body Hopfield model with finite connectivity
Yushi Sugawara, Koji Hukushima
A three-body Hopfield model defined on sparse random graphs with finite mean connectivity is studied using a replica-symmetric (RS) analysis. By extending the functional replica fr…

Structure-resolved free energy estimation of the 38-atom Lennard Jones cluster via population annealing
Akie Kowaguchi, Koji Hukushima
We systematically investigate the thermodynamic landscape of the 38-atom Lennard--Jones cluster LJ using Population Annealing (PA), a method suited for systems with challeng…
