چکیده

We consider the Hamiltonian system consisting of scalar wave eld and a single particle coupled in a translation invariant manner. The point particle is subject to a connning external potential. The stationary solutions of the system are a Coulomb type wave eld centered at those particle positions for which the external force vanishes. We prove that solutions of nite energy converge, in suitable local energy seminorms, to the set of stationary solutions in the long time limit t ! 1. The rate of relaxation to a stable stationary solution is determined by spatial decay of initial data.

Asymptotics for the infinite time ruin probability of a dependent risk model with a constant interest rate and dominatedly varying-tailed claim sizes

 This paper mainly considers a nonstandard risk model with a constant interest rate‎, ‎where both the claim sizes and the inter-arrival times follow some certain dependence structures‎. ‎When the claim sizes are dominatedly varying-tailed‎, ‎asymptotics for the infinite time ruin probability of the above dependent risk model have been given‎.

Classical Limit for Scalar Fields at High Temperature

We study real-time correlation functions in scalar quantum field theories at temperature T = 1/β. We show that the behaviour of soft, long wave length modes is determined by classical statistical field theory. The loss of quantum coherence is due to interactions with the soft modes of the thermal bath. The soft modes are separated from the hard modes by an infrared cutoff Λ ≪ 1/(¯ hβ). Integrat...

Localizing of a Four-Level Atom via Absorption Spectrum

We propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field. In the classical standing wave field, the interaction between the atom and the field is position dependent due to the Rabi-frequency of the driving field. Hence, as the absorption frequency of the probe field is mea...

Gaussian-beam propagation in generic anisotropic wave-number profiles.

The propagation characteristics of a scalar Gaussian beam in a homogeneous anisotropic medium are considered. The medium is described by a generic wave-number profile wherein the field is formulated by a Gaussian plane-wave distribution and the propagation is obtained by saddle-point asymptotics to extract the Gaussian beam phenomenology in the anisotropic environment. The resultant field is pa...
