Automatic structural optimization of tree tensor networks
Toshiya Hikihara, Hiroshi Ueda, Kouichi Okunishi +2
Tree tensor network (TTN) provides an essential theoretical framework for the practical simulation of quantum many-body systems, where the network structure defined by the connecti…
Geometric decomposition of entropy production into excess, housekeeping and coupling parts
Andreas Dechant, Shin-ichi Sasa, Sosuke Ito
For a generic overdamped Langevin dynamics driven out of equilibrium by both time-dependent and nonconservative forces, the entropy production rate can be decomposed into two posit…
Thermodynamic role of main reaction pathway and multi-body information flow in membrane transport
Satoshi Yoshida, Yasushi Okada, Eiro Muneyuki +1
The two classes of membrane transport, namely, secondary active and passive transport, are understood as different reaction pathways in the same protein structure, described by the…
Developments in the Tensor Network -- from Statistical Mechanics to Quantum Entanglement
Kouichi Okunishi, Tomotoshi Nishino, Hiroshi Ueda
Tensor networks (TNs) have become one of the most essential building blocks for various fields of theoretical physics such as condensed matter theory, statistical mechanics, quantu…
Thermodynamic uncertainty relation and thermodynamic speed limit in deterministic chemical reaction networks
Kohei Yoshimura, Sosuke Ito
We generalize thermodynamic uncertainty relation (TUR) and thermodynamic speed limit (TSL) for deterministic chemical reaction networks (CRNs). The scaled diffusion coefficient der…
Geometrical aspects of entropy production in stochastic thermodynamics based on Wasserstein distance
Muka Nakazato, Sosuke Ito
We study a relationship between optimal transport theory and stochastic thermodynamics for the Fokker-Planck equation. We show that the lower bound on the entropy production is the…
