Fundamental Superstrings as Holograms [PDF]
, 2007 The worldsheet of a macroscopic fundamental superstring in the Green-Schwarz light-cone gauge is viewed as a possible boundary hologram of the near horizon region of a small black string.

M-Theory (the Theory Formerly Known as Strings) [PDF]
, 1996 Superunification underwent a major paradigm shift in 1984 when eleven-dimensional supergravity was knocked off its pedestal by ten-dimensional superstrings.

Integrated massive vertex operator in pure spinor formalism
Journal of High Energy Physics, 2018 We construct the integrated vertex operator for the first massive states of open superstrings with (mass)2 = 1/α ′ in the pure spinor formalism of the superstring theory. This vertex operator is expressed in terms of the ten dimensional N = 1 $$ \mathcal{

Journal of High Energy Physics, 2022 In this paper we consider non-commutativity that arises from T-duality of bosonic coordinates of type II superstring in presence of coordinate dependent Ramond-Ramond field. Action with such choice of the background fields is not translational invariant.

Theta expansion of first massive vertex operator in pure spinor
Journal of High Energy Physics, 2018 We provide the covariant superspace equations that are sufficient to determine the complete θ expansion of the vertex operator of the open string massive states with (mass)2 = 1/α′ in pure spinor formalism of superstring theory.

Strings from Membranes and Fivebranes [PDF]
, 1996 Under the six-dimensional heterotic/type $IIA$ duality map, a solitonic membrane solution of heterotic string theory transforms into a singular solution of type $IIA$ theory, and should therefore be interpreted as a fundamental membrane in the latter ...

Integrating three-loop modular graph functions and transcendentality of string amplitudes
Journal of High Energy Physics, 2022 Modular graph functions (MGFs) are SL(2, ℤ)-invariant functions on the Poincaré upper half-plane associated with Feynman graphs of a conformal scalar field on a torus.

The Universality of M-branes [PDF]
, 1996 We review the evidence for the various dualities amongst the five D=10 superstring theories and for the existence of M-theory using the associated effective supergravity theories.

A Note on the dS Swampland Conjecture, Non‐BPS Branes and K‐Theory
Fortschritte der Physik, Volume 67, Issue 11, November 2019., 2019 Abstract We point out that the de Sitter swampland conjecture would be falsified if classical fluxed Type IIA orientifold vacua with a single non‐BPS D7‐brane were indeed part of the string theory landscape. In other words, the dS swampland conjecture implies the cancellation of K‐theory charges on a compact space.

Modular graph functions and odd cuspidal functions. Fourier and Poincaré series
Journal of High Energy Physics, 2019 Modular graph functions are SL(2, ℤ)-invariant functions associated with Feynman graphs of a two-dimensional conformal field theory on a torus of modulus τ. For one-loop graphs they reduce to real analytic Eisenstein series. We obtain the Fourier series,
