Superadiabatic forces in Brownian many-body dynamics.
Theoretical approaches to nonequilibrium many-body dynamics generally rest upon an adiabatic assumption, whereby the true dynamics is represented as a sequence of equilibrium states. Going beyond this simple approximation is a notoriously difficult problem. For the case of classical Brownian many-body dynamics, we present a simulation method that allows us to isolate and precisely evaluate supe...
متن کاملSuperadiabatic Transitions in Quantum Molecular Dynamics
We study the dynamics of a molecule’s nuclear wave-function near an avoided crossing of two electronic energy levels, for one nuclear degree of freedom. We derive the general form of the Schrödinger equation in the n-th superadiabatic representation for all n ∈ N. Using these results, we obtain closed formulas for the time development of the component of the wave function in an initially unoccu...
متن کاملSuperadiabatic Transition Histories in Quantum Molecular Dynamics
We study the dynamics of a molecule’s nuclear wave-function near an avoided crossing of two electronic energy levels, for one nuclear degree of freedom. We derive the general form of the Schrödinger equation in the n-th superadiabatic representation for all n ∈ N, and give some partial results about the asymptotics for large n. Using these results, we obtain closed formulas for the time develop...
متن کاملRapid acceleration in dogs: ground forces and body posture dynamics.
Because the ability to accelerate rapidly is crucial to the survival and reproductive fitness of most terrestrial animals, it is important to understand how the biomechanics of rapid acceleration differs from that of steady-state locomotion. Here we compare rapid acceleration with high-speed galloping in dogs to investigate the ways in which body and limb posture and ground forces are altered t...
