Hamiltonian approach to Ehrenfest expectation values and Gaussian quantum states.
The dynamics of quantum expectation values is considered in a geometric setting. First, expectation values of the canonical observables are shown to be equivariant momentum maps for the action of the Heisenberg group on quantum states. Then, the Hamiltonian structure of Ehrenfest's theorem is shown to be Lie-Poisson for a semidirect-product Lie group, named the Ehrenfest group. The underlying P...
متن کاملRegularization of Toda lattices by Hamiltonian reduction
The Toda lattice defined by the Hamiltonian H = 12 ∑n i=1 p 2 i + ∑n−1 i=1 νie qi−qi+1 with νi ∈ {±1}, which exhibits singular (blowing up) solutions if some of the νi = −1, can be viewed as the reduced system following from a symmetry reduction of a subsystem of the free particle moving on the group G = SL(n,RI ). The subsystem is T Ge, where Ge = N+AN− consists of the determinant one matrices...

متن کاملReal Hamiltonian forms of Hamiltonian systems
We introduce the notion of a real form of a Hamiltonian dynamical system in analogy with the notion of real forms for simple Lie algebras. This is done by restricting the complexified initial dynamical system to the fixed point set of a given involution. The resulting subspace is isomorphic (but not symplectomorphic) to the initial phase space. Thus to each real Hamiltonian system we are able t...
متن کاملEhrenfest-time Dependence of Counting Statistics for Chaotic Ballistic Systems
Transport properties of open chaotic ballistic systems and their statistics can be expressed in terms of the scattering matrix connecting incoming and outgoing wavefunctions. Here we calculate the dependence of correlation functions of arbitrarily many pairs of scattering matrices at different energies on the Ehrenfest time using trajectory based semiclassical methods. This enables us to verify...
