Long-lived memory in sliding spin chains
Charles Stahl, Ethan Lake
We study a system of two ferromagnetic one-dimensional Ising chains coupled to a thermal bath, which are driven out of equilibrium by being moved past one another at a constant spe…
Brownian ratchets and pumps universally simulate many-body active dynamics
Charles Stahl, Ethan Lake, Vedika Khemani
Active systems can exhibit a broad range of phenomena forbidden in equilibrium. Their dynamics are often specified by abstract local update rules, and it is generally unclear when…
Exploring the Landscape of Non-Equilibrium Memories with Neural Cellular Automata
Ehsan Pajouheshgar, Aditya Bhardwaj, Nathaniel Selub +1
We investigate the landscape of many-body memories: families of local non-equilibrium dynamics that retain information about their initial conditions for thermodynamically long tim…
Squeezing codes: robust fluctuation-stabilized memories
Ethan Lake, Sunghan Ro
We introduce families of classical stochastic dynamics in two and higher dimensions which stabilize order in the absence of any symmetry. Our dynamics are qualitatively distinct fr…
