Instant cosmology

Journal of High Energy Physics
Instant Folded Strings (IFSs) are unconventional light strings that emerge when the string coupling increases with time. A particularly intriguing property of IFSs, especially relevant to cosmology, is that they violate the Null Energy Condition (NEC ...

Torus bundles, automorphisms and T-duality

Journal of High Energy Physics, 2021
We reconsider some older constructions of T-duality, based on automorphisms of the worldsheet operator algebra, in a modern context. It has been long known that at special points in the moduli space of torus compactifications, the target space gauge ...

Pseudoscalar Field as a Possible Candidate for Phantom Field

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We demonstrate the existence of a single pseudoscalar (PS) field in the mathematically backed and parity‐preserving modifications of the standard Stückelberg formalism (SSF) in the context of the Lagrangian formulation of the (i) two (1 + 1)‐dimensional (2D) massive Abelian 1‐form gauge theory, (ii) three (2 + 1)‐dimensional (3D) massive Abelian 2‐form

Bosonic Description of Spinning Strings in $2+1$ Dimensions [PDF]

, 1996
We write down a general action principle for spinning strings in 2+1 dimensional space-time without introducing Grassmann variables. The action is written solely in terms of coordinates taking values in the 2+1 Poincare group, and it has the usual string

T‐Symmetry in String Geometry Theory

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Zero Modes on Linked Strings

, 1994
We study linked loops of string in the presence of bosonic condensates and fermionic zero modes on the strings. We find that the strings necessarily carry a current if the bosons have an Aharanov-Bohm interaction with the string.

Strings with interacting ends [PDF]

, 1995
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.

Modified 3D Massive Abelian 2‐Form Theory With a Single Pseudoscalar Field as a Phantom Field: BRST Approach

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We obtain the off‐shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti‐BRST symmetry transformations (corresponding to the infinitesimal classical gauge symmetry transformations) for the modified massive three (2 + 1)‐dimensional (3D) Abelian two‐form gauge theory with a single pseudoscalar field. The latter field (having the negative kinetic term

A new approach to superstring

Journal of High Energy Physics
We show how starting with one-string space of states in BRST formalism one can construct a large class of physical quantities containing, in particular, scattering amplitudes for bosonic string and superstring.

Open String Renormalization Group Flow as a Field Theory

Fortschritte der Physik, Volume 72, Issue 11, November 2024.
Abstract This article shows that the integral flow‐lines of the RG‐flow of open string theory can be interpreted as the solitons of a Hořova–Lifshitz sigma‐model of open membranes. The authors argue that the effective background description of this model implies the g‐theorem of open string theory.
