Double field theory and geometric quantisation

Journal of High Energy Physics, 2021
We examine various properties of double field theory and the doubled string sigma model in the context of geometric quantisation. In particular we look at T-duality as the symplectic transformation related to an alternative choice of polarisation in the ...

A duality in string theory on AdS3

Journal of High Energy Physics, 2023
Abstract We consider bosonic string theory on AdS3 supported by Kalb-Ramond flux. It is well known that the α′ exact worldsheet theory is described by the SL(2,R) WZW model. In this note we perform checks of an α′ exact dual description proposed in [arXiv:2104.07233] involving a winding condensate on a free theory background.

Topological open/closed string dualities: matrix models and wave functions

Journal of High Energy Physics, 2019
We sharpen the duality between open and closed topological string partition functions for topological gravity coupled to matter. The closed string partition function is a generalized Kontsevich matrix model in the large dimension limit.

Gaugino Condensation, Duality and Supersymmetry Breaking [PDF]

, 1995
The status of gaugino condensation in low-energy string theory is reviewed. Emphasis is given to the determination of the efective action below condensation scale in terms of the 2PI and Wilson actions.

Odderon in gauge/string duality [PDF]

Journal of High Energy Physics, 2009
At high energies, elastic hadronic cross sections, such as $pp, \overline p p, ^{\pm} p$, are dominated by vacuum exchange, which in leading order of the $1/N_c$ expansion has been identified as the BFKL Pomeron or its strong AdS dual the closed string Reggeized graviton \cite{Brower:2006ea}.

Graded Hydroxyapatite Triply Periodic Minimal Surface Structures for Bone Tissue Engineering Applications

Advanced Healthcare Materials, EarlyView.
This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

Advanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Effective action of heterotic string theory at order α′2

Journal of High Energy Physics, 2023
Upon examining the effective action of the heterotic string theory at order α′2, an inconsistency between the Chern-Simons coupling Ω2 and T-duality has been discovered. To address this issue, we introduce 60 parity-even independent geometrical couplings

T-Duality and Double Field Theory [PDF]

, 2016
The purpose of this thesis is to study a symmetry of string theory known as T-duality. We focus on a particular example establishing the equivalence between a quantized string moving in a circular space of radius R and a dual string moving in a similar ...
