What does a six-dimensional figure look like? Theoretical physicist Richard Nally can’t show you exactly, but he does have a sculpture – a pink shape the size of a grapefruit – that can help you imagi...
The Resurgence of Instantons in String Theory
Instantons Resurgent Analysis Topological and Minimal Strings Matrix Models
2011/7/29
Abstract: Nonperturbative effects in string theory are usually associated to D-branes. In many cases it can be explicitly shown that D-brane instantons control the large-order behavior of string pertu...
D1-brane in Constant R-R 3-form Flux and Nambu Dynamics in String Theory
D1-brane Constant R-R 3-form Flux Nambu Dynamics String Theory

We consider D1-string in a constant R-R 3-form flux background and analyze its low energy limit. The leading order low energy theory has reparametrization symmetry and is a generalization of an earli...
We examine the behavior of the leading Regge trajectory of the open bosonic string in a uniform electromagnetic background and present a consistent set of Fierz-Pauli conditions for these symmetric t...
Non-perturbative String Theory from Water Waves
Non-perturbative String Theory Water Waves
2010/12/24
We use a combination of a 't Hooft limit and numerical methods to find non-perturbative solutions of exactly solvable string theories, showing that perturbative solutions in different asymptotic regim...
We construct a model of quintessence in string theory based on the idea of axion monodromy as discussed by McAllister, Silverstein and Westphal arXiv:0808.0706. In the model, the quintessence field is...
Gauge Mediated Supersymmetry Breaking and String Theory
Gauge Mediated Supersymmetry Breaking String Theory
2010/12/24
We discuss the possibility of finding scenarios within type IIB string theory compactified on Calabi-Yau orientifolds with fluxes, for realizing gauge mediated supersymmetry breaking. We find that whi...
The Cosmological Constant Problem from the Point of View of String Theory
The Cosmological Constant Problem View String Theory
2010/12/24
The quantum field theory prediction of the cosmological constant is 120 orders of magnitude higher than the observed value. This is known as the cosmological constant problem. Here, we deal with the ...
In these lecture notes, we take a closer look at the calculation of scattering amplitudes for the bosonic string. It is believed that string theories form the UV completions of (super)gravity theorie...
We propose a string theory of turbulence that explains the Kolmogorov scaling in 3+1 dimensions and the Kraichnan and Kolmogorov scalings in 2+1 dimensions. This string theory of turbulence should be ...

Noncommutativity in String Theory and Large Extra Dimensions
Noncommutativity String Theory Large Extra Dimensions
2010/4/15
Noncommutativity of space coordinates of string theory are reviewed and are related to the large extra dimension solution of the hierarchy problem.
