An excursion into the string spectrum

Journal of High Energy Physics, 2023
We propose a covariant technique to excavate physical bosonic string states by entire trajectories rather than individually. The approach is based on Howe duality: the string’s spacetime Lorentz algebra commutes with a certain inductive limit of sp ...

Trotterless Simulation of Open Quantum Systems for NISQ Quantum Devices

Advanced Quantum Technologies, Volume 8, Issue 1, January 2025.
Open quantum systems exhibit complex dynamics that can be simulated on quantum computers to provide physical insights into their behavior. This work proposes a new method for simulating these systems that reduces the effect of noise and errors on modern quantum hardware.

A vertex operator algebra construction of the colour-kinematics dual numerator

Journal of High Energy Physics, 2018
We derive a vertex operator based expression for the kinematic numerators of Yang-Mills amplitudes by applying the momentum kernel formalism to open string amplitudes. The expression involves an α ′ -weighted commutator induced by the monodromy relations

T-duality of non-relativistic string in torsional Newton-Cartan background

Journal of High Energy Physics, 2020
In this short note we analyse T-duality properties of non-relativistic string in torsional Newton-Cartan background. We also determine condition that ensures that non-relativistic string maps to non-relativistic string under T-duality.

Gravitating Semilocal strings

, 2009
We discuss the properties of semilocal strings minimally coupled to gravity. Semilocal strings are solutions of the bosonic sector of the Standard Model in the limit $\sin^2\theta_W=1$ (where $\theta_W$ is the Weinberg angle) and correspond to embedded ...

Strings Near a Rindler Or Black Hole Horizon [PDF]

, 1994
Orbifold techniques are used to study bosonic, type II and heterotic strings in Rindler space at integer multiples N of the Rindler temperature, and near a black hole horizon at integer multiples of the Hawking temperature, extending earlier results of ...

Harmonic balls in Liouville quantum gravity

Proceedings of the London Mathematical Society, Volume 130, Issue 1, January 2025.
Abstract Harmonic balls are domains that satisfy the mean‐value property for harmonic functions. We establish the existence and uniqueness of harmonic balls on Liouville quantum gravity (LQG) surfaces using the obstacle problem formulation of Hele–Shaw flow.

The fate of (phantom) dark energy universe with string curvature corrections

, 2005
We study the evolution of (phantom) dark energy universe by taking into account the higher-order string corrections to Einstein-Hilbert action with a fixed dilaton.

Moduli Space Dimensions of Multi-Pronged Strings [PDF]

, 1999
The numbers of bosonic and fermionic zero modes of multi-pronged strings are counted in ${\cal N}=4$ super-Yang-Mills theory and compared with those of the IIB string theory.

Symmetries in the Hamiltonian Formulation of String Theory

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
In the context of the Hamiltonian formulation of string theory, a widely acknowledged issue is the inability of the first‐class constraints to accurately reproduce the Lagrangian symmetry transformations. We take a critical look at the Hamiltonian formulation of the Polyakov string and demonstrate, using Castellani′s procedure, that diffeomorphism and ...
