Multifractality and Hyperuniformity in Quasicrystalline Bose-Hubbard Models with and without Disorder
Masahiro Hori, Takanori Sugimoto, Yoichiro Hashizume +1
Clarifying similarities and differences in physical properties between crystalline and quasicrystalline systems is one of central issues in studying quasicrystals. To contribute to…
Singular-value decomposition using quantum annealing
Yoichiro Hashizume, Takashi Koizumi, Kento Akitaya +3
In the present study, we demonstrate how to perform, using quantum annealing, the singular value decomposition and the principal component analysis. Quantum annealing gives a way t…
A new perspective to formulate a dissipative thermo field dynamics
Yoichiro Hashizume, Masuo Suzuki, Soichiro Okamura
In the present study, we propose a new perspective on thermal dissipation based on the thermo field dynamics. From the view point of the renormalization theory, there appear effect…
Information Geometry for Husimi-Temperley Model
Yoichiro Hashizume, Hiroaki Matsueda
We examine phase transition of the Husimi-Temperley model in terms of information geometry. For this purpose, we introduce the Fisher metric defined by the density matrix of the mo…
Comment on "Snapshot spectrum and critical phenomenon for two-dimensional classical spin systems"
Hiroaki Matsueda, Ching Hua Lee, Yoichiro Hashizume
This is a comment on arXiv:1402.6767 (2014) by Y. Imura, T. Okubo, S. Morita, and K. Okunishi.
Order formation processes of complex systems including different parity order parameters
Yoichiro Hashizume, Masuo Suzuki, Soichiro Okamura
In the present study, we focus on the parity of the order parameters and clarify the order formation process in a system including two order parameters. Each order parameter shows…
Understanding quantum entanglement by thermo field dynamics
Yoichiro Hashizume, Masuo Suzuki
We propose a new method to understand quantum entanglement using the thermo field dynamics (TFD) described by a double Hilbert space. The entanglement states show a quantum-mechani…
Analytical Condition for Synchrony in a Neural Network with Two Periodic Inputs
Yoichiro Hashizume, Osamu Araki
In this study, we apply a mean field theory to the neural network model with two periodic inputs in order to clarify the conditions of synchronies. This mean field theory yields a…
Tensor Network and Black Hole
Hiroaki Matsueda, Masafumi Ishihara, Yoichiro Hashizume
A tensor network formalism of thermofield dynamics is introduced. The formalism relates the original Hilbert space with its tilde space by a product of two copies of a tensor netwo…
New Random Ordered Phase in Isotropic Models with Many-body Interactions
Yoichiro Hashizume, Masuo Suzuki
In this study, we have found a new random ordered phase in isotropic models with many-body interactions. Spin correlations between neighboring planes are rigorously shown to form a…
