Non-Supersymmetric String Theory (2009)

Martinec, Emil J., Robbins, Daniel, Sethi, Savdeep

A class of non-supersymmetric string backgrounds can be constructed using twists that involve space-time fermion parity. We propose a non-perturbative definition of string theory in these backgrounds...

On Slow-roll Moduli Inflation in Massive IIA Supergravity with Metric Fluxes (2008)

Flauger, Raphael, Paban, Sonia, Robbins, Daniel, Wrase, Timm

We derive several no-go theorems in the context of massive type IIA string theory compactified to four dimensions in a way that, in the absence of fluxes, preserves N=1 supersymmetry. Our derivation...

Facetmap: A scalable search and browse visualization (2008)

Greg Smith, Mary Czerwinski, Brian Meyers, Daniel Robbins, George Robertson, Desney S. Tan

Abstract — The dominant paradigm for searching and browsing large data stores is text-based: presenting a scrollable list of search results in response to textual search term input. While this...

Submitted for review to AVI2002 Scope: Providing Awareness of Multiple Notifications at a Glance (2008)

Maarten Van Dantzich, Daniel Robbins, Eric Horvitz, Mary Czerwinski

We describe the design and functionality of the Scope, a glanceable notification summarizer. The Scope is an information visualization designed to unify notifications and ameliorate distractions. It...

Broue's Abelian Defect Group Conjecture for the Tits Group (2008)

Robbins, Daniel

In this paper we prove that Broue's abelian defect group conjecture holds for the Tits group $^2F_4(2)'$. Also we prove that under certain conditions we are able to lift derived equivalences and use...

General F-Term Gauge Mediation (2008)

Distler, Jacques, Robbins, Daniel

In a model-independent formalism of gauge mediation, Meade, Seiberg, and Shih have shown that hidden sector effects are captured by two-point correlation functions of the gauge current superfields...

Interfaces – graphical user interfaces, windowing systems. (2007)

George Robertson, Eric Horvitz, Mary Czerwinski, Patrick Baudisch, Dugald Hutchings, Brian Meyers, ...

Our studies have shown that as displays become larger, users leave more windows open for easy multitasking. A larger number of windows, however, may increase the time that users spend arranging and...

Corresponding Author: (2007)

Kim Cameron, Mary Czerwinski, Daniel Robbins, George Robertson, George Robertson

We describe a new information structure composed of multiple intersecting hierarchies, which we call a Polyarchy. Visualizing polyarchies enables use of novel views for discovery of relationships...

Ramond-Ramond Fields, Cohomology and Non-Geometric Fluxes (2007)

Bergman, Aaron, Robbins, Daniel

We consider compactifications of type II string theory in which a d-dimensional torus is fibered over a base X. In string theory, the transition functions of this fibration need not be simply...

D-Terms from Generalized NS-NS Fluxes in Type II (2007)

Robbins, Daniel, Wrase, Timm

Orientifolds of type II string theory admit a certain set of generalized NS-NS fluxes, including not only the three-form field strength H, but also metric and non-geometric fluxes, which are related...

Toroidal Orientifolds in IIA with General NS-NS Fluxes (2007)

Ihl, Matthias, Robbins, Daniel, Wrase, Timm

Type IIA toroidal orientifolds offer a promising toolkit for model builders, especially when one includes not only the usual fluxes from NS-NS and R-R field strengths, but also fluxes that are T-dual...

Toward the End of Time (2006)

Martinec, Emil J., Robbins, Daniel, Sethi, Savdeep

The null-brane space-time provides a simple model of a big crunch/big bang singularity. A non-perturbative definition of M-theory on this space-time was recently provided using matrix theory. We...

A Matrix Model for the Null-Brane (2005)

Robbins, Daniel, Sethi, Savdeep

The null-brane background is a simple smooth 1/2 BPS solution of string theory. By tuning a parameter, this background develops a big crunch/big bang type singularity. We construct the DLCQ...

A Barren Landscape? (2004)

Robbins, Daniel, Sethi, Savdeep

We consider the generation of a non-perturbative superpotential in F-theory compactifications with flux. We derive a necessary condition for the generation of such a superpotential in F-theory. For...

Scalable Fabric: Flexible Task Management (2004)

George Robertson Eric, Eric Horvitz, Mary Czerwinski, Patrick Baudisch, Dugald Hutchings, Brian Meyers, ...

Our studies have shown that as displays become larger, users leave more windows open for easy multitasking. A larger number of windows, however, may increase the time that users spend arranging and...

The UV/IR Interplay in Theories with Space-time Varying Non-commutativity (2003)

Robbins, Daniel, Sethi, Savdeep

We consider scalar field theory with space and space-time-dependent non-commutativity. In perturbation theory, we find that the structure of the UV/IR mixing is quite different from cases with...

Time-Dependent Warping, Fluxes, and NCYM (2003)

Dasgupta, Keshav, Rajesh, Govindan, Robbins, Daniel, Sethi, Savdeep

We describe the supergravity solutions dual to D6-branes with both time-dependent and time-independent B-fields. These backgrounds generalize the Taub-NUT metric in two key ways: they have asymmetric...
