Bohmian dynamics
WebWhile in Newtonian mechanics the dynamics of the point particles is determined by a second order differential equation d2Q t dt2 = 1 m F(Q t), (1) in which F(Q) is a force field, e.g, derived from a potential field V as F(Q) = −∇V, in Bohmian mechanics the point particles dynamics is given by a first order differential equation dQ t dt ...
