Abstract: Abstract In this paper, we investigate whether dynamic incentive schemes lead to a ratchet effect in a social dilemma. We test whether subjects strategically restrict their contribution levels at the beginning of a cumulative public… read more here.

DOI: 10.1103/physrevb.103.045406
Abstract: The magnetic ratchet effect has been studied in phosphorene by the use of the Boltzmann kinetic equation, which is a semiclassical approach. The Hamiltonian of phosphorene in a steady parallel magnetic field is derived using… read more here.

DOI: 10.1103/physrevlett.122.135502
Abstract: The propagation front of a crack generates large strain gradients and it is therefore a strong source of gradient-induced polarization (flexoelectricity). Herein, we demonstrate that, in piezoelectric materials, a consequence of flexoelectricity is that crack… read more here.

DOI: 10.3390/e19040119
Abstract: The stochastic model of the Feynman–Smoluchowski ratchet is proposed and solved using generalization of the Fick–Jacobs theory. The theory fully captures nonlinear response of the ratchet to the difference of heat bath temperatures. The ratchet… read more here.
