Casimir interaction of finite-width strings
نویسندگان
چکیده
Within the trln-formalism we investigate vacuum interaction of cosmic strings and influence width on this effect. For massless real scalar field compute Casimir contribution into total energy. The dimensional-regularization technique is used. It shown that regularized term contains neither UV-divergences, nor divergences related with non-integrability renormalized mean energy-momentum tensor.

In this paper we propose an efficient method to model the amount of bow hair in contact with the string in a physical model of a bowed string instrument.
متن کاملFinite Temperature Strings ∗
In this talk a review of earlier work on finite temperature strings was presented. Several topics were covered, including the canonical and microcanonical ensemble of strings, the behavior of strings near the Hagedorn temperature as well as speculations on the possible phases of high temperature strings. The connection of the string ensemble and, more generally, statistical systems with an expo...
متن کاملCasimir Interaction: Pistons and Cavity
The energy of a perfectly conducting rectangular cavity is studied by making use of pistons’ interactions. The exact solution for a 3D perfectly conducting piston with an arbitrary cross section is being discussed.
متن کاملFinite width of shear zones.
We present some experimental and numerical results based on a simple model designed to give an estimate for the width of a shear zone. We conclude that the observed finite size of the shear zone can be associated with the propagation of the force lines inside the medium. The model, based on a simple argument on the force distribution and dilatancy, predicts a width of about ten grain diameters.
