Asymptotic Behavior of Saxion–Axion System in Stringy Quintessence Model
Abstract The late time behavior of the slow‐roll parameter in the stringy quintessence model is studied when axion as well as saxion are allowed to move. Even though the potential is independent of the axion at tree level, the axion can move through its coupling to the saxion and the background geometry.

Supergravity and local extended supersymmetry
Abstract We consider the possibility of having supergravity theories with several (N > 2) Majorana spin 3 2 gauge fields. From the spinor dual model one can infer the existence of these theories with (Yang-Mills) matter coupling up to N = 4 spin 3 2 gauge fields. In the present note we construct the simplest of these theories, i.e. pure

Focus point supersymmetry in extended gauge mediation [PDF]
We propose a small extenion of the minimal gauge mediation through the combination of extended gauge mediation and conformal sequestering. We show that the focus point supersymmetry can be realized naturally, and the fine-tuning is signifcantly reduced compared to the minimal gauge mediation and extended gauge mediation without focus point.

Predicting Alignment in a Two Higgs Doublet Model
We show that a non-abelian global S U ( 2 ) R R-symmetry acting on the quartic part of the two Higgs Doublet Model leads, at tree-level, to an automatic alignment without decoupling.

de Sitter State in Heterotic String Theory
Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Interface‐Interactive Nanoarchitectonics: Solid and/or Liquid
As the concept of post‐nanotechnology, the new concept of nanoarchitectonics is now emerging. However, such structural control and fabrication are not always easy. A realistic methodology to control such structures is the use of interfacial environments. In this review paper, under the title of interface‐interactive nanoarchitectonics, several examples

Camouflaged supersymmetry in solutions of extended supergravities
We establish a relation between certain classes of flux compactifications and certain families of black hole microstate solutions. This connection reveals a rather unexpected result: there exist supersymmetric solutions of N=8 supergravity that live inside many N=2 truncations, but are not supersymmetric inside any of them.

A proposal for 0 extended supersymmetry in integrable systems [PDF]
Utilizing techniques suggested by the recently obtained construction of off-shell spinning particles, we propose the arbitrary $N$-extension of supersymmetry for the KdV system. It is further suggested that the ${\aleph}_0$ extension for the SKdV system provides a paradigm for {\underline {all}} supersymmetric completely integrable systems.

Moduli anomalies and local terms in the operator product expansion
Local terms in the Operator Product Expansion in Superconformal Theories with extended supersymmetry are identified. Assuming a factorized structure for these terms their contributions are discussed.
