Entanglement entropy for open bosonic strings on Dp-branes [PDF]

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2018
We study the entanglement entropy for open bosonic strings on multiple Dp-branes by using the covariant open string field theory. Choosing one of the spatial coordinates which are tangential to the hyperplane on which Dp-branes are located, we divide the

Quantum carrollian bosonic strings [PDF]

Journal of High Energy Physics
We study a recently discovered carrollian bosonic string, described classically by a sigma model where both the worldsheet and the target spacetime are carrollian.

Fractional bosonic strings [PDF]

Journal of Mathematical Physics, 2018
The aim of this paper is to present a simple generalization of bosonic string theory in the framework of the theory of fractional variational problems. Specifically, we present a fractional extension of the Polyakov action, for which we compute the general form of the equations of motion and discuss the connection between the new fractional action and ...

Entanglement entropy and Fisher information metric for closed bosonic strings in homogeneous plane wave background [PDF]

Physical Review D, 2017
We derive the extended renormalized entanglement entropy (EREE) and the Fisher information metric in the case of closed bosonic strings in homogeneous plane wave background.

New BPS states from bosonic/heterotic duality [PDF]

Journal of High Energy Physics
In this paper, we consider the recently proposed bosonic/heterotic duality that relates the heterotic superstrings to the noncritical bosonic string. Although the latter is nonsupersymmetric, it can be viewed as pseudo-supersymmetric in that the theory ...

Scattering amplitudes of regularized bosonic strings [PDF]

Physical Review D, 2017
We compute scattering amplitudes of the regularized bosonic Nambu-Goto string in the mean-field approximation, disregarding fluctuations of the Lagrange multiplier and an independent metric about their mean values.

QUANTUM GEOMETRY OF BOSONIC STRINGS

Physics Letters B, 1981
We develop a formalism for computing sums over random surfaces which arise in all problems containing gauge invariance (like QCD, three-dimensional Ising model etc.). These sums are reduced to the exactly solvable quantum theory of the two-dimensional Liouville lagrangian.

On the covariant quantization of tensionless bosonic strings in AdS spacetime [PDF]

Journal of High Energy Physics, 2003
The covariant quantization of the tensionless free bosonic (open and closed) strings in AdS spaces is obtained. This is done by representing the AdS space as an hyperboloid in a flat auxiliary space and by studying the resulting string constrained ...

Bosonic technicolor in strings

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1992
Abstract It is shown that strings provide a natural theoretical setting for bosonic technicolor. In particular, bosonic technicolor structure arises in a class of strings formulated in four dimensions. An example of a model with three generations and multi-Higgs structure is presented.
