However, a common approach for the statistical mechanics of polymer chains, the Gaussian chain approximation, misses key physics. By considering the ...

The viscosity coefficient represents broken time-reversal and parity symmetries in the 2D fluid and characterizes the deviation of the system from a passive fluid. Taking into accoun...

In particular, we develop a perturbative approach for the model of activ...

We investigate granular flows for a large range of inclination angles from $\theta =13.{4}^{\circ}$ to 83.6° and various gate openings of the chute.
