Department Colloquium *Special*: "Solving the Solar Neutrino Problem"

Joshua Klein (UPenn) Hosted by Gene Beier

We will discuss the work of the Sudbury Neutrino Observatory, and the Penngroup in particular, that provided the solution to the long-standing Solar Neutrino Problem and which has been recognized this year by the…

Astro Seminar: "The Scale-Dependence of Halo Assembly Bias"

Tomomi Sunayama (Yale University)

The clustering of dark matter halos is influenced by halo
properties besides mass, a phenomenon referred to as halo assembly
bias. It is because halos of the same mass in different environments
have…

High Energy Theory Seminar: "TBA"

Simone Giombi (Princeton)

Rittenhouse Lecture:" Expansion of the Universe seen by Hubble"

Adam Reiss (JHU/STScI) Hosted by Adam Lidz

The Hubble constant remains one of the most important parameters in the cosmological model, setting the size and age scales of the Universe.  Present uncertainties in the cosmological model including the nature of…

Adam Riess (Johns Hopkins University/STScI)

The Hubble constant remains one of the most important parameters in the cosmological model, setting the size and age scales of the Universe.  Present uncertainties in the cosmological model including the nature of…

Condensed Matter seminar: "Microfluidics of sugar transport in plants"

Kaare H. Jensen, Technical University of Denmark

Plants can rightly be called masters of microengineering. Their survival and successful reproduction depends on their ability to overcome a series of physical challenges during growth and when transporting matter…

High Energy Theory Seminar: "TBA"

Eric Perlmutter (Princeton)

Special Condensed Matter seminar: "Topological gapped and gapless phases protected by nonsymmorphic lattice symmetries"

Chen Fang, Massachusetts Institute of Technology

In the first part of the talk, I will show that a nonsymmorphic glide reflection symmetry can protect a new Z2 topological gapped phase in three-dimensions. Unlike topological insulators, this new phase can be…

Astro Seminar: "Overview of Planck Data and (Cosmological and Astrophyical) Results "

Graca Rocha (JPL)

In this talk I will give an overview of Planck data and Cosmological and Astrophysical results: Temperature and polarization maps of the Cosmic Microwave Background radiation anisotropies, Power Spectra, Likelihoods…
