Compactification Without Orientation, or a Topological Scenario for CP Violation Open
In higher dimensional theories, we often assume that the extra dimensions form an orientable space, perhaps with singularities. However, many physical theories are well-defined on non-orientable spaces, and many spaces are not orientable, …

Back to the future: Causality on a moving braneworld Open
Brane observers executing appropriate motion through a partially compactified Lorentz invariant bulk spacetime, such as M4 × S1, can send signals along the brane that are instantaneous or even travel backward in time. Nevertheless, causali…

Superluminal propagation on a moving braneworld Open
We consider a braneworld scenario in the simplest setting, M4 × S1, with a four-dimensional (4D) Minkowski metric induced on the brane, and establish the possibility of superluminal propagation. If the brane is at rest, the 4D Lorentz symm…

Back to the Future: Causality on a Moving Braneworld Open
Brane observers executing appropriate motion through a partially compactified Lorentz invariant bulk spacetime, such as $M_4 \times S^1$, can send signals along the brane that are instantaneous or even travel backward in time. Nevertheless…

Superluminal Propagation on a Moving Braneworld Open
We consider a braneworld scenario in the simplest setting, $M_4 \times S^1$, with a 4D Minkowski metric induced on the brane, and establish the possibility of superluminal propagation. If the brane is at rest, the 4D Lorentz symmetry of th…

Kink Collisions in Curved Field Space Open
Here, we study bubble universe collisions in the ultrarelativistic limit with the new feature of allowing for nontrivial curvature in field space. We establish a simple geometrical interpretation of such collisions in terms of a double fam…

Weeding a shared e-book collection: Collaboration across a consortium Open
Collection weeding is an important function of any library operation. At its simplest, the process of deciding what to remove, and implementing it, is controlled by a library or system serving a single mission and set of objectives. This b…

Validation of short-term noise assessment procedures : FY16 summary of procedures, progress, and preliminary results Open
Army regulations require that installations assess the impacts of training range noise on wildlife and the human community. This work provides a summary of the work performed in fiscal year (FY) 2016 for the Environment, Safety and Occupat…

Random Field Theories in The Mirror Quintic Moduli Space Open
We investigate the distribution of field theories that arise from the low energy limit of flux vacua built on type IIB string theory compactified on the mirror quintic. For a large collection of these models, we numerically determine the d…

Numerical Evaluation of Accelerated-Assisted Entanglement Harvesting Open
We consider acceleration-assisted entanglement harvesting as evidenced in correlations between two accelerating Unruh detectors coupled to a scalar field. We elaborate on earlier studies, which in a stationary phase approximation calculate…
