#### Homoclinics for Lagrangian systems on Riemannian manifolds

(Dynamic Publishers Atlanta, 1992)

#### Femtosecond luminescence spectroscopy of carrier thermalization in GaAs and InP

(IOP PUBLISHING LTD, 1992)

Thermalization of a non-equilibrium distribution of electrons and holes generated by femtosecond photoexcitation is studied in GaAs and InP via spectrally and temporally resolved luminescence. In both materials, a rapid ...

#### Vacuum correlations in quantum gravity

(ELSEVIER SCIENCE BV, 1992)

We give a lowest-order estimation of some invariant correlation functions of quantized Einstein gravity in any dimension N > 2. The non-perturbative evaluation of such functions would play an important role in the Monte ...

#### The propagator in the radial gauge

(AMER INST PHYSICS, 1992)

The solutions of the equation for the propagator in the radial gauge x(mu)A(mu)(x) = 0 are studied. After finding a particular solution GAMMA(mu-rho)(x,y), the most general solution G(mu-rho)0(x,y) of the homogeneous ...

#### On the motion of test particles in a fluctuating gravitational field

(AMER INST PHYSICS, 1992)

In this paper the "free fall" motion of a test tetrad in a weak gravitational field is studied. This is done with the intention of exploring the geometry locally through geodesics and parallel transport. By use of the ...

#### Vacuum correlations in quantum gravity

(Springer, 1992)

We give a lowest-order estimation of some invariant correlation functions of quantized Einstein gravity in any dimension N > 2. The non-perturbative evaluation of such functions would play an important role in the Monte ...
