Abstract

Large extra dimensions have been proposed as an explanation for the anomalous weakness of the gravitational force. In this work, I present a new kind of constraint on a range of extra dimension models that derives from recent theoretical work exploring the possibility that our Higgs vacuum is meta-stable, leading to possibilities for catastrophic vacuum decay, either spontaneous or triggered by evaporating black holes.

Quantum entanglement, described by Einstein as "spooky action at a distance," is both fascinating philosophically and is the basis for quantum computing and quantum encryption. For this reason, it deserves to be tested in experiments that push entanglement to its limits. The inferred power of entanglement rests on several assumptions, including that the measurement chosen for one particle can be made independent of any influence that can affect the other particle.

Soft Condensed Matter Seminar

Abstract

Concentrated suspensions of hard particles such as cornstarch in water exhibit shear thickening, a non-Newtonian fluid behavior in which an increasing shear rate causes the effective viscosity of the fluid to increase, and even support a load or crack like a solid.  Such suspensions can even be strong enough to support a person walking or running on the surface of the fluid.  These material properties are promising for applications such as rate-dependent dampers and impact protection.
