Universal interface fluctuations in absorbing-state phase transitions
Yohsuke T. Fukai, Keiichi Tamai, Tetsuya Hiraiwa
Despite similarities between models exhibiting absorbing phase transitions (APTs) and those showing Kardar-Parisi-Zhang (KPZ) growth, the relationship between these universal fluct…
Universal Scaling Laws of Absorbing Phase Transitions in Artificial Deep Neural Networks
Keiichi Tamai, Tsuyoshi Okubo, Truong Vinh Truong Duy +2
We demonstrate that conventional artificial deep neural networks operating near the phase boundary of the signal propagation dynamics, also known as the edge of chaos, exhibit univ…
Data Assimilation Method for Experimental and First-Principles Data: Finite-Temperature Magnetization of (Nd,Pr,La,Ce)(Fe,Co,Ni)B
Yosuke Harashima, Keiichi Tamai, Shotaro Doi +8
We propose a data-assimilation method for evaluating the finite-temperature magnetization of a permanent magnet over a high-dimensional composition space. Based on a general framew…
How to experimentally probe universal features of absorbing phase transitions using steady state
Keiichi Tamai, Masaki Sano
We propose experimentally feasible ways to probe universal features of absorbing phase transitions from two different approaches, both based on numerical validations. On one hand,…
A Universal Transition to Turbulence in Channel Flow
Masaki Sano, Keiichi Tamai
Transition from laminar to turbulent flow drastically changes the mixing, transport, and drag properties of fluids, yet when and how turbulence emerges is elusive even for simple f…
