Synopsis: Collective Dynamics from Particular person Random Walks

November 14, 2019 The jerky, random movement of micro organism has now been reproduced utilizing synthetic microswimmers, yielding collective behaviors much like these of real-world bacterial swarms.      H. Karani et al., Phys. Rev. Lett. (2019) An experiment that emulates the random movement of a sperm cell or a self-propelling bacterium has reproduced a number of the collective dynamics seen in teams of those microswimmers. A workforce lead by Petia Vlahovska at Northwestern College in…

Synopsis: Simulations Unravel Fibers’ Twisted Topology

November 13, 2019 How an elastic filament deforms beneath stress has been quantified in simulations, with implications for the design of synthetic muscle tissue. N. Charles et al., Phys. Rev. Lett. (2019) Future generations of robots and prosthetic gadgets would require compact synthetic muscle tissue which can be highly effective and environment friendly. One method to make such muscle tissue is to twist elastic fibers in order that they coil up and shorten in response…

Viewpoint: Equilibration in Quantum Methods

Sebastian Deffner, Quantum Thermodynamics Group, Division of Physics, College of Maryland, Baltimore County, Baltimore, MD, USA November 13, 2019• Physics 12, 123 Two analysis teams present that particular contributions to entropy stands out as the key to understanding how and when quantum techniques equilibrate. Determine 1: Regardless of how onerous you strive, time can’t be reversed to make a shattered egg complete once more. This so-called arrow of time is defined in physics by the…
