We study the energy extraction from and charging to a finite-dimensional quantum system by general operations. prove that changes in induced unital operations are limited ergotropy/charging bound for unitary This implies that, order break operations, one needs perform operation with feedback control. also show applied initial thermal equilibrium states, is tighter than inequality representing s...

Recent work is revealing neural correlates of a leading theory motor control. By linking an elegant series behavioral experiments with inactivation in macaques computational models, new study shows that premotor and parietal areas can be mapped onto model for optimal feedback We are constantly adapting. Whether it to shoes, or walking on icy terrain, we have the capacity continually update our ...
