Superstring D-Branes
We study T-duality, D-branes, and orbifolds in the Type II and Type I superstring theories where they present new interesting phenomena. We compute...

Bosonic String: T-Duality & D-Branes
In this textbook, the main emphasis is on supersymmetric string theories. We use the bosonic string merely as a kindergarten laboratory to introduce...

10d Superstring Theories
In this chapter, we construct and classify all superstring theories whose world-sheet theories have a (1, 1) superconformal algebra of gauge...

Instanton solutions in open superstring field theory
Open superstring field theory admits a “hybrid” formulation where N = 1 D = 4 supersymmetry is manifest for Calabi-Yau compactifications to four...

Worldsheet description of a massive type IIA superstring in 10D
We construct, following [
1 ,2 ], a massive M2-brane (supermembrane) as the limit of a genus two M2-brane that becomes a twice... -
Pure Spinor Formulation of the Superstring and Its Applications
The pure spinor formalism for the superstring has the advantage over the more conventional Ramond-Neveu-Schwarz formalism of being manifestly...

Euclidean D-branes in type IIB string theory on Calabi-Yau threefolds
We compute the contribution of Euclidean D-branes in type IIB string theory on Calabi-Yau threefolds to the metric on the hypermultiplet moduli space...

On finite-size d-branes in superstring theory
We test exact marginality of the deformation describing the blow-up of a zero- size D( − 1) brane bound to a background of D3-branes by analyzing the...

Non-extremal, α′-corrected black holes in 5-dimensional heterotic superstring theory
We compute the first-order α ′ corrections of the non-extremal Strominger-Vafa black hole and its non-supersymmetric counterparts in the framework of...

D-branes in AdS3 × S3 × 𝕋4 at k = 1 and their holographic duals
String theory on AdS 3 × S 3 × 𝕋 4 with minimal k = 1 NS-NS flux can be described in terms of a free field worldsheet theory in the hybrid formalism....

Closed string deformations in open string field theory. Part II. Superstring
This is the second paper of a series of three. We construct effective open-closed superstring couplings by classically integrating out massive fields...

Application to Superstring Theory
The last chapter describes an example of solving the inverse problem of string theory as an application of deep learning. The superstring theory...

Toward simulating superstring/M-theory on a quantum computer
We present a novel framework for simulating matrix models on a quantum computer. Supersymmetric matrix models have natural applications to...

Dual D-brane actions in nonrelativistic string theory
We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string...

Newton-Cartan D0 branes from D1 branes and integrability
We explore analytic integrability criteria for D 1 branes probing 4D relativistic background with a null isometry direction. We use both the Kovacic’s...

Scattering three closed strings off a Dp-brane in pure spinor formalism
We compute the disk amplitude of three closed strings in the pure spinor formalism. Among others, this amplitude probes tree-level gravitational...

Supersymmetric instantonic D1-branes in AdS5
× S5 backgroundAccording to the covariant open superstring description of 1/2-BPS D-branes in the AdS 5 ×S 5 background, there are two kinds of purely instantonic...

More on effective potentials for revolving D-branes
We continue to investigate the effective potential between a pair of D p -branes revolving around each other by using the technique of partial modular...

D-brane and F-theory Model Building
We review recent progress in the construction of four-dimensional vacua of Type II string theory and F-theory which yield the Standard Model of...

LREE of an unstable dressed-dynamical Dp-brane: superstring calculations
We obtain the left-right entanglement entropy (LREE) for a D p -brane with tangential motion in the presence of a U (1) gauge potential, the Kalb–Ramond...
