Aftershocks and fluctuating diffusivity
Sumiyoshi Abe, Norikazu Suzuki, Dmitrii A. Tayurskii
The Omori-Utsu law shows the temporal power-law-like decrease of the frequency of earthquake aftershocks and, interestingly, is found in a variety of complex systems/phenomena exhi…
Scaling and memory in seismological phenomena
Sumiyoshi Abe, Norikazu Suzuki
The concept of memory is of central importance for characterizing complex systems and phenomena. Presence of long-term memories indicates how their dynamics can be less sensitive t…
Crossover in extended Newtonian gravity emerging from thermodynamics
Sumiyoshi Abe, Peter Ván
In a recent paper (Ván, P.; Abe, S. Physica A 2022, 588, 126505), it has been discovered that a scalar field coupled to a fluid and allowed to be a thermodynamic variable in consis…
Quantum weak invariants: Dynamical evolution of fluctuations and correlations
Zeyi Shi, Sumiyoshi Abe
Weak invariants are time-dependent observables with conserved expectation values. Their fluctuations, however, do not remain constant in time. On the assumption that time evolution…
Fast-forward scheme reexamined: Choice of time and quantization
Sumiyoshi Abe
The fast-forward scheme for accelerating time evolution of quantum states through change of time is reexamined. Dirac's homogeneous formalism for classical dynamics and canonical q…
Emergence of extended Newtonian gravity from thermodynamics
Peter Ván, Sumiyoshi Abe
Discovery of a novel thermodynamic aspect of nonrelativistic gravity is reported. Here, initially, an unspecified scalar field potential is considered and treated not as an externa…
