Ferromagnetic Haldane state and dimer multiplet state of quantum ferromagnets
Shin Miyahara, Isao Maruyama
We present a theory of the realization of a ferromagnetic Haldane state in a spin-2 bilinear-biquadratic spin system on an orthogonal-dimer chain. The coexistence of a ferromagneti…
Application of the path optimization method to a discrete spin system
Kouji Kashiwa, Yusuke Namekawa, Akira Ohnishi +1
The path optimization method, which is proposed to control the sign problem in quantum field theories with continuous degrees of freedom by machine learning, is applied to a spin m…
Theory of Fractionally-magnetized Quantum Ferromagnet
Isao Maruyama, Shin Miyahara
We present a theory to realize entangled quantum spin states with fractional magnetization. The origin of magnetization reduction is partly emergent antiferromagnetism, that is, sp…
Evaluating generation of chaotic time series by convolutional generative adversarial networks
Yuki Tanaka, Yutaka Yamaguti
To understand the ability and limitations of convolutional neural networks to generate time series that mimic complex temporal signals, we trained a generative adversarial network…
Factors determining surface oxygen vacancy formation energy in ternary spinel structure oxides with zinc
Yoyo Hinuma, Shinya Mine, Takashi Toyao +2
Spinel oxides are an important class of materials for heterogeneous catalysis including photocatalysis and electrocatalysis. The surface O vacancy formation energy (EOvac) is a cri…
Instability of holographic cold compact stars with a color superconducting core
Kazuo Ghoroku, Kouji Kashiwa, Yoshimasa Nakano +2
We study a holographic model of quantum chromodynamics, which can describe a color superconductor and a dilute nucleon gas phase. The two phases are adjoined in the phase diagram a…
