At the classical level we study open bosonic strings. A generic description of string self–interactions localized at string ends is given. Self–interactions are characterized by two dimensionless coupling constants. The model is rewritten using complex Liouville fields. Using these Lorentz and reparametrization invariant variables, equations of motion get greatly simplified and reduce to some b...
متن کاملInteracting Strings of Characters
We consider several interacting strings of characters. Otherwise speaking, we consider one-dimensional random walks interacting with each other and with their environments (mostly in a one-sided manner). This embraces many applications: queueing networks with diierent customer types, random walks on some discrete non-commutative groups, random Turing machines and others. We present a scheme for...
متن کاملCosmic strings with interacting hot dark matter
We compute the linear power spectrum of cosmic string sedeed fluctuations in the context of neutrinos with a strong self-interaction and show that it is very similar to that obtained in the context of ‘normal’ neutrinos. We compare our results with observational data and show that for any value of the cosmological parameters h and Ω0 the interacting hot dark matter power spectrum requires a lar...
متن کاملSupermembrane dynamics from multiple interacting strings
A method for the calculation of the supermembrane spectrum on R 10 × S 1 is investigated , for membranes that wrap once around the compact dimension. The membrane theory is represented in terms of a Hamiltonian describing N s interacting strings, the exact supermembrane corresponding to N s → ∞. The connection with type IIA superstring theory requires that the zero-mode part of N s −1 strings b...
متن کاملBundles of interacting strings in two dimensions
Bundles of strings which interact via short-ranged pair potentials are studied in two dimensions. The corresponding transfer matrix problem is solved analytically for arbitrary string number N by Bethe ansatz methods. Bundles consisting of N identical strings exhibit a unique unbinding transition. If the string bundle interacts with a hard wall, the bundle may unbind from the wall via a unique ...
