Path integrals of perturbative strings on curved backgrounds from string geometry theory [PDF]

open access: yesarXiv, 2022
String geometry theory is one of the candidates of the non-perturbative formulation of string theory. In this paper, from the closed bosonic sector of string geometry theory, we derive path integrals of all order perturbative strings on all the string backgrounds, $G_{\mu\nu}(x)$, $B_{\mu\nu}(x)$, and $\Phi (x)$, by considering fluctuations around the ...

The Static String [PDF]

open access: yesMod. Phys. Lett. A29 (3) 1450018 (2014), 2013
In this article the quantum fluctuation of a rigid and static string is reported to be identical to a free quantum particle. Solutions similar to this static string have already been found in the semi-classical quantizaton of pulsating strings, and our results show that the semi-classical quantization of pulsating strings is, in some cases, a ...

Superstring amplitudes, unitarily, and Hankel determinants of multiple zeta values

open access: yesJournal of High Energy Physics, 2019
The interplay of unitarity and analyticity has long been known to impose strong constraints on scattering amplitudes in quantum field theory and string theory. This has been highlighted in recent times in a number of papers and lecture notes.

Conformal geometric method study open strings and closed strings relationships on Dirichlet branes [PDF]

open access: yesarXiv, 2018
The compactness of the closed string in the classical Type II string theory reveals the duality, whereas the compactness of the open string reveals that the end of the string is on the hypersurface which satisfies the Dirichlet boundary condition.

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

open access: yesAdvanced 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).

A tale of two exponentiations in N $$ \mathcal{N} $$ = 8 supergravity at subleading level

open access: yesJournal of High Energy Physics, 2020
High-energy massless gravitational scattering in N $$ \mathcal{N} $$ = 8 supergravity was recently analyzed at leading level in the deflection angle, uncovering an interesting connection between exponentiation of infrared divergences in momentum space ...

Holographic RG flows and Janus solutions from matter-coupled $$N=4$$ N = 4 gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We study an $$SO(2)\times SO(2)\times SO(2)\times SO(2)$$ S O ( 2 ) × S O ( 2 ) × S O ( 2 ) × S O ( 2 ) truncation of four-dimensional $$N=4$$ N = 4 gauged supergravity coupled to six vector multiplets with $$SO(4)\times SO(4)$$ S O ( 4 ) × S O ( 4 ...

Towards open-closed string duality: Closed Strings as Open String Fields [PDF]

open access: yesarXiv, 2006
We establish a translation dictionary between open and closed strings, starting from open string field theory. Under this correspondence, (off-shell) level-matched closed string states are represented by star algebra projectors in open string field theory. Particular attention is paid to the zero mode sector, which is indispensable in order to generate
