String Sigma Models on Curved Supermanifolds
We use the techniques of integral forms to analyze the easiest example of two-dimensional sigma models on a supermanifold. We write the action as an integral of a top integral form over a D = 2 supermanifold, and we show how to interpolate between ...

Stability and vacuum energy in open string models with broken supersymmetry
We construct type I string models with supersymmetry broken by compactifi- cation that are non-tachyonic and have exponentially small effective potential at one-loop.

String breaking in a cold wind as seen by string models
Using the gauge/string duality, we model a heavy quark-antiquark pair in a color singlet state moving through a cold medium and explore the consequences of temperature and velocity on string breaking. In doing so, we restrict to the case of two dynamical

Thraxions: towards full string models
We elucidate various aspects of the physics of thraxions, ultra-light axions arising at Klebanov-Strassler multi-throats in the compactification space of IIB superstring theory.

Stringballs and Planckballs for dark matter
As a follow up of the seminal work by Guiot, Borquez, Deur, and Werner on “Graviballs and Dark Matter”, we explicitly show that in string theory, local and nonlocal higher derivative theories, as well as general asymptotically-free or finite theories ...

On physical models in V.I. Gulyayev's three papers on drill string whirling and torsional vibrations
This paper introduces physical models of drill string whirling and torsional vibrations and analyses the physical models in V.I. Gulyayev's three papers on drill string whirling and torsional vibrations: “V.I. Gulyayev, L.V.

Fine-tuned vs. natural supersymmetry: what does the string landscape predict?
A vast array of (metastable) vacuum solutions arise from string compactifications, each leading to different 4-d laws of physics. The space of these solutions, known as the string landscape, allows for an environmental solution to the cosmological ...

Radiative natural supersymmetry emergent from the string landscape
In string theory with flux compactifications, anthropic selection for structure formation from a discretuum of vacuum energy values provides at present our only understanding of the tiny yet positive value of the cosmological constant.
