Systematic study of the SO(10) symmetry breaking vacua in the matrix model for type IIB superstrings [PDF]

Journal of High Energy Physics, 2011
We study the properties of the space-time that emerges dynamically from the matrix model for type IIB superstrings in ten dimensions. We calculate the free energy and the extent of space-time using the Gaussian expansion method up to the third order.

Explicit superstring vacua in a background of gravitational waves and dilaton [PDF]

Il Nuovo Cimento A, 1995
We present an explicit solution of superstring effective equations, represented by gravitational waves and dilaton backgrounds. Particular solutions will be examined in a forthcoming note.

BPS Saturated Dyonic Black Holes of $N=8$ Supergravity Vacua [PDF]

, 1995
We summarize the results for four-dimensional Bogomol'nyi-Prasad- Sommerfield (BPS) saturated dyonic black hole solutions arising in the Kaluza-Klein sector and the three-form field sector of the eleven-dimensional supergravity on a seven-torus.

Closed String Amplitudes as Single-Valued Open String Amplitudes [PDF]

, 2014
We show that the single trace heterotic N-point tree-level gauge amplitude A_HET can be obtained from the corresponding type I amplitude A_I by the single-valued (sv) projection: A_HET=sv(A_I).

A Heterotic Standard Model [PDF]

, 2005
Within the context of the E_8 x E_8 heterotic superstring compactified on a smooth Calabi-Yau threefold with an SU(4) gauge instanton, we show the existence of simple, realistic N=1 supersymmetric vacua that are compatible with low energy particle ...

Holography for Non-Critical Superstrings [PDF]

, 1999
We argue that a class of ``non-critical superstring'' vacua is holographically related to the (non-gravitational) theory obtained by studying string theory on a singular Calabi-Yau manifold in the decoupling limit $g_s\to 0$.

Mirror Symmetry and Landau Ginzburg Calabi-Yau Superpotentials in F-theory Compactifications [PDF]

, 2001
We study Landau Ginzburg (LG) theories mirror to 2D N=2 gauged linear sigma models on toric Calabi-Yau manifolds. We derive and solve new constraint equations for Landau Ginzburg elliptic Calabi-Yau superpotentials, depending on the physical data of dual

S and U-duality Constraints on IIB S-matrices [PDF]

, 2000
S and U-duality dictate that graviton scattering amplitudes in IIB superstring theory be automorphic functions on the appropriate fundamental domain which describe the inequivalent vacua of (compactified) theories.

de-Sitter vacua via consistent D-terms [PDF]

, 2005
We introduce a new mechanism for producing locally stable de-Sitter or Minkowski vacua, with spontaneously broken N=1 supersymmetry and no massless scalars, applicable to superstring and M-theory compactifications with fluxes. We illustrate the mechanism
