String bits and the Myers effect
Based on the non-abelian effective action for D1-branes, a new action for matrix string theory in non-trivial backgrounds is proposed. Once the background fields are included, new interactions bring the possibility of non-commutative solutions i.e. The Myers effect for “string bits” .
متن کاملBits and Relative Order From Residues, Space Efficiently
For each k, let P k be the product of the rst k primes. By the Chinese remainder theorem, each integer in the interval 0;P k) is determined by its residues modulo these k primes. We address the problems of space-eeciently computing the bits and the relative order of such numbers from their residues.
متن کاملQuantum Phase Space from String Solitons
In this paper we view the σ-model couplings of appropriate vertex operators describing the interaction of string matter with a certain type of string solitons (0-branes) as the quantum phase space of a point particle. The σ-model is slightly non critical, and therefore one should dress it with a Liouville mode. Quantization is achieved by summing over worldsheet genera (in the pinched approxima...
متن کاملCalculating the rest tension for a polymer of string bits.
We explore the application of approximation schemes from many body physics, including the Hartree-Fock method and random phase approximation (RPA), to the problem of analyzing the low energy excitations of a polymer chain made up of bosonic string bits. We accordingly obtain an expression for the rest tension T0 of the bosonic relativistic string in terms of the parameters characterizing the mi...
متن کاملThe Space of String Diagrams
where M is a closed, compact, oriented Riemannian manifold, LM is the space of continuous maps from the circle into M–the free loop space of M–and C∗(LM) is the complex of singular chains on LM . Inspired by an idea in [6], chain-level string topology operations were constructed in [5] using a subspace of our space of string diagrams. This subspace • has a different homotopy type from the space...
