SL(2, R) model with two Hamiltonian constraints
General relativity (GR) has a characteristic gauge invariance, which implies that its canonical Hamiltonian vanishes weakly. As a consequence, its dynamics is not governed by a genuine Hamiltonian, but rather by a “Hamiltonian constraint”. This peculiar feature of the theory has a crucial physical significance, connected to the relational nature of the general-relativistic spatiotemporal notion...
متن کاملHamiltonian Quantum Dynamics With Separability Constraints
Schroedinger equation on a Hilbert space H, represents a linear Hamiltonian dynamical system on the space of quantum pure states, the projective Hilbert space PH. Separable states of a bipartite quantum system form a special submanifold of PH. We analyze the Hamiltonian dynamics that corresponds to the quantum system constrained on the manifold of separable states, using as an important example...

متن کاملQuantization of a generally covariant gauge system with two super Hamiltonian constraints
The Becci-Rouet-Stora-Tyutin (BRST) operator quantization of a finitedimensional gauge system featuring two quadratic super Hamiltonian and m linear supermomentum constraints is studied as a model for quantizing generally covariant gauge theories. The proposed model “completely” mimics the constraint algebra of general relativity. The Dirac constraint operators are identified by realizing the B...
متن کاملStabilized Integration of Hamiltonian Systems with Hard-Sphere Inequality Constraints
We consider numerical methods for resolving the dynamics of a Hamiltonian Nbody problem subject to hard-sphere inequality constraints. The dynamics of these mixed systems consists of smooth flow of a Hamiltonian system between collisions with an impulsive momentum exchange at the points of collision. The inclusion of these impulses makes traditional backward error analysis inappropriate since t...
