We review the general aspects of the concept of temperature in equilibrium and non-
equilibrium statistical mechanics. Although temperature is an old and well-established …

We review recent studies of a colloidal information engine that consists of a bead in water
and held by an optical trap. The bead is ratcheted upward without any apparent external …

Information engines can convert thermal fluctuations of a bath at temperature T into work at
rates of order k BT per relaxation time of the system. We show experimentally that such …

We study the rectification of voltage fluctuations in a system consisting of two Coulomb-
coupled quantum dots. The first quantum dot is connected to a reservoir where voltage …

For a wide class of stochastic athermal systems, we derive Langevin-like equations driven
by non-Gaussian noise, starting from master equations and developing a new asymptotic …

Traditional models for molecular (Brownian) motors predominantly depend on
nonequilibrium driving, while particle interactions rigorously adhere to Newton's third law …

In an active bath, besides thermal noise, immersed passive objects also persistently
experience collisions from active particles, which are often coarse-grained into a colored …

In the present study, we have investigated the Allison mixture, a variant of the Parrondo's
games where random mixing of two random sequences creates autocorrelation. We have …

Sperm motility is a prerequisite for male fertility. Enhancing the concentration of motile
sperms in assisted reproductive technologies–for human and animal reproduction–is …

We present an experimental realization at macroscopic scale of the storied Brownian
ratchet, which is an illustration of the Maxwell's demon. In our mechanism, the rotation of a …
