Electric/magnetic duality and its stringy origins [PDF]
, 1995 We review electric/magnetic duality in $N=4$ (and certain $N=2$) globally supersymmetric gauge theories and show how this duality, which relates strong to weak coupling, follows as a consequence of a string/string duality.

Heterotic string solutions and coset conformal field theories [PDF]
Nucl.Phys.B409:339-362,1993, 1993 We discuss solutions of the heterotic string theory which are analogous to bosonic and superstring backgrounds related to coset conformal field theories. A class of exact `left-right symmetric' solutions is obtained by supplementing the metric, antisymmetric tensor and dilaton of the superstring solutions by the gauge field background equal to the ...

Topological amplitude computations using the pure spinor formalism
Journal of High Energy Physics, 2019 After constructing a simplified four-dimensional version of the b ghost, topological multiloop amplitudes in type II superstring theory compactified on a six-dimensional orbifold are computed using the non-minimal pure spinor formalism. These pure spinor

On the equivalence between SRS and PCO formulations of superstring perturbation theory
Journal of High Energy Physics, 2023 We establish the equivalence between two formulations of superstring perturbation theory, one based on integration over the supermoduli space of super Riemann surfaces (SRS), the other based on integration over the bosonic moduli space with insertions of

Dual String Pairs With N=1 And N=2 Supersymmetry In Four Dimensions [PDF]
, 1995 Based on a simple adiabatic argument and by considering the heterotic string counterpart of certain symmetries of Type II superstrings such as $(-1)^{F_L}$ and orientation reversal, we construct orbifold candidates for dual pairs of heterotic and Type II

String Theory Dynamics In Various Dimensions [PDF]
Nucl.Phys.B443:85-126,1995, 1995 The strong coupling dynamics of string theories in dimension $d\geq 4$ are studied. It is argued, among other things, that eleven-dimensional supergravity arises as a low energy limit of the ten-dimensional Type IIA superstring, and that a recently conjectured duality between the heterotic string and Type IIA superstrings controls the strong coupling ...

Amplitudes involving massive states using pure spinor formalism
Journal of High Energy Physics, 2018 Same amplitudes evaluated independently using RNS and pure spinor formalism are expected to agree. While for massless states, this fact has been firmly established, for massive states such an explicit check has been lacking so far.

Random Walks in Rindler Spacetime and String Theory at the Tip of the Cigar [PDF]
, 2014 In this paper, we discuss Rindler space string thermodynamics from a thermal scalar point of view as an explicit example of the results obtained in JHEP 1402 (2014) 127.

On the Chiral Fermions in the Twistor--Like Formulation of D=10 Heterotic String [PDF]
Phys.Lett.B326:84-88,1994, 1993 An n=8 worldsheet superfield action is proposed for describing chiral fermions in the twistor-like formulation of an N=1, D=10 heterotic superstring.

Heterotic Type I Strings at High Temperature [PDF]
Physical Review D98 (2018) 046017, 2018 We show that the high temperature limits of the heterotic E8xE8 and Spin(32)/Z2 strings and their Type I A/B superstring duals are finite and convergent. The Hagedorn growth of the degeneracies in the string mass level expansion is suppressed by an exponential linear in the mass level number for both heterotic strings, and suppressed by the exponential
