Continuous black-box optimization with quantum annealing and random subspace coding
Syun Izawa, Koki Kitai, Shu Tanaka +2
A black-box optimization algorithm such as Bayesian optimization finds extremum of an unknown function by alternating inference of the underlying function and optimization of an ac…
Expanding the horizon of automated metamaterials discovery via quantum annealing
Koki Kitai, Jiang Guo, Shenghong Ju +4
Complexity of materials designed by machine learning is currently limited by the inefficiency of classical computers. We show how quantum annealing can be incorporated into automat…
Quantum Phase Transition in Fully-Connected Quantum Wajnflasz-Pick Model
Yuya Seki, Shu Tanaka, Shiro Kawabata
We construct a quantum Wajnflasz-Pick model that is a generalized quantum Ising model, and investigate a nature of quantum phase transitions of the model with infinite-range intera…
Applicability of scaling behavior and power laws in the analysis of the magnetocaloric effect in second-order phase transition materials
Carlos Romero-Muñiz, Ryo Tamura, Shu Tanaka +1
In recent years, universal scaling has gained renewed attention in the study of magnetocaloric materials. It has been applied to a wide variety of pure elements and compounds, rang…
Topological and dynamical properties of a generalized cluster model in one dimension
Takumi Ohta, Shu Tanaka, Ippei Danshita +1
We study the ground-state phase diagram and dynamics of the one-dimensional cluster model with several competing interactions. Paying particular attention to the relation between t…
Phase diagram and sweep dynamics of a one-dimensional generalized cluster model
Takumi Ohta, Shu Tanaka, Ippei Danshita +1
We numerically study quantum phase transitions and dynamical properties in the one-dimensional cluster model with several interactions by using the time-evolving block decimation m…
