We investigate the thermalization behavior of one-dimensional ϕ^{4} lattices with the help of the self-consistent phonon theory. As the energy density increases, we observe the double-scaling behavior of the thermalization time as a functi...

P O Adesina et al.
We have investigated the dynamics of a phase-modulated driven gyroscope, including vibrational resonance (VR) phenomena and the stability of the system, both with and without phase modulation. For appropriate choices of parameters, three di...
Exact mean and variance of the squared Hellinger distance for random density matrices [0.03%]

The Hellinger distance between quantum states is a significant measure in quantum information theory, known for its Riemannian and monotonic properties. It is easier to compute than the Bures distance, another measure that shares these prop...
Broken-parity-induced crossover of thermal conduction in the Fermi-Pasta-Ulam-Tsingou lattice [0.03%]

Fairness plays a key role in collective decision-making such as international trade, burden sharing in global climate change, and prey allocation after hunting. The two-player ultimatum game has facilitated a large body of research on fair ...
Temporal coarse graining and elimination of slow and periodic dynamics with the generalized Langevin equation for convolution-time-filtered observables [0.03%]

By exact projection in phase space, we derive the generalized Langevin equation (GLE) for convolution-time-filtered observables. We employ a general convolution filter that directly acts on arbitrary phase-space observables and can involve ...
Out-of-equilibrium quantum thermochemical engine with one-dimensional Bose gas [0.03%]

Understanding diffusive mass transport in fluid flows is fundamental in several fields, ranging from virus particles in chromatographic test kits to nutrients in ocean currents. However, experimentally resolving diffusion processes in flowi...
Beyond the median voter: A model of how the ideological dimension shapes party polarization [0.03%]

Defying the median voter theorem, party polarization has spread globally, especially in the United States. As concerns grow over its risks to democracy, political science has probed its causes, revealing two paradoxes: while polarization be...
Nonequilibrium replication process generates the initial template for chromatin folding [0.03%]
