Geometric Thermodynamics of Scallop Motion with Two Control Parameters
Hisao Hayakawa
According to Purcell's scallop theorem, reciprocal single-degree-of-freedom shape deformations cannot achieve net propulsion in a viscous fluid. We show that this limitation is byp…
Non-Hermitian Random Matrix Theory of Jamming in Active Disordered Media
Hisao Hayakawa
We develop a theoretical framework for the mechanics of active jammed systems based on non-Hermitian random matrix theory. Starting from a microscopic model of active particles wit…
Quantum tunneling Mpemba effect
Hisao Hayakawa, Satoshi Takada
We investigate a quantum tunneling Mpemba effect for a particle in a continuous one-dimensional symmetric double-well potential subject to irreversible boundary loss. The dissipati…
Mpemba effect in a two-dimensional bistable potential
Hisao Hayakawa, Satoshi Takada
We present an exactly solvable model of the Mpemba effect in an overdamped Langevin system confined to a two-dimensional, radially symmetric bistable potential. The potential is co…
