, 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.

Phase Noise in Real‐World Twin‐Field Quantum Key Distribution
Advanced Quantum Technologies, Volume 7, Issue 6, June 2024.This study explores the impact of various noise sources on twin‐field quantum key distribution (TF‐QKD) systems, focusing on phase noise from photon sources and fibers. Results show that different TF‐QKD protocols are similarly affected by phase noise.

Hamiltonian and Lagrangian constraints of the bosonic string [PDF]
Physical Review D, 1986 We study the Hamiltonian and Lagrangian constraints of the Polyakov string. The gauge fixing at the Hamiltonian and Lagrangian level is also studied.

Effective potential for revolving D-branes
Journal of High Energy Physics, 2019 We quantize an open string stretched between D0-branes revolving around each other. The worldsheet theory is analyzed in a rotating coordinate system in which the worldsheet fields obey simple boundary conditions, but instead the worldsheet Lagrangian ...

Topological recursion for Kadomtsev–Petviashvili tau functions of hypergeometric type
Journal of the London Mathematical Society, Volume 109, Issue 6, June 2024.Abstract We study the n$n$‐point differentials corresponding to Kadomtsev–Petviashvili (KP) tau functions of hypergeometric type (also known as Orlov–Scherbin partition functions), with an emphasis on their ℏ2$\hbar ^2$‐deformations and expansions.

Quantisation of the bosonic string [PDF]
, 2017 In this work we review the basic principles of the theory of the relativistic bosonic string through the study of the action functionals of Nambu-Goto and Polyakov and the techniques required for their canonical, light-cone, and path-integral quantisation.

Cosmic Rays from Cosmic Strings with Condensates
, 2009 We re-visit the production of cosmic rays by cusps on cosmic strings. If a scalar field (``Higgs'') has a linear interaction with the string world-sheet, such as would occur if there is a bosonic condensate on the string, cusps on string loops emit ...

Exploring T‐Duality for Self‐Dual Fields
Fortschritte der Physik, Volume 72, Issue 5, May 2024.Abstract Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions are studied. This formalism is shown to naturally accommodate the T‐duality relation between Type IIA/IIB theories when compactified on a circle without the need for imposing the self‐duality constraint by hand, as is usually done. The study of this

The first α′-correction to homogeneous Yang-Baxter deformations using O(d, d)
Journal of High Energy Physics, 2020 We use the O(d, d)-covariant formulation of supergravity familiar from Double Field Theory to find the first α′-correction to (unimodular) homogeneous Yang-Baxter (YB) deformations of the bosonic string.

Pair Creation of Open Strings in an Electric Field
, 1992 We calculate exactly the rate of pair production of open bosonic and supersymmetric strings in a constant electric field. The rate agrees with Schwinger's classic result in the weak-field limit, but diverges when the electric field approaches some ...
