Physics and Astronomy Colloquium

Christopher Mauger (University of Pennsylvania)
- David Rittenhouse Laboratory, A8



Physics and Astronomy Colloquium: "Top Down Approach to Quantum Fields"

Jonathan Heckman (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

Quantum Field Theory (QFT) is the common language of particle physicists, cosmologists, and condensed matter physicists. Even so, many fundamental aspects of QFT remain poorly understood. In this…



Physics and Astronomy Colloquium: "Next-generation Doppler Spectrometers"

Cullen Blake (University of Pennsylvania
- David Rittenhouse Laboratory, A8

The Doppler technique is a key tool for discovering and characterizing planets orbiting other stars. By measuring the reflex motion of the host star as the star and planet orbit a common center of mass, “extrasolar”…



Rittenhouse Lecture: “The Illustris TNG hydrodynamic simulation of the Universe”

Lars Hernquist (Harvard University)
- David Rittenhouse Laboratory, A8

A predictive theory of galaxy formation remains elusive, even after more than 50 years of dedicated effort by many renowned astrophysicists.  The problem of galaxy formation is made difficult by the large range in…

Past Department Colloquia



Physics and Astronomy Colloquium: "Dynamics of living flows"

Eleni Katifori (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

Complex life larger than a humble nematode would not be possible without a circulatory system. Plants, fungi, and animals have developed vascular systems of striking complexity to solve problems of long…



Department Colloquium (joint with CBE): "Structuring Matter over Multiple Length Scales using the Self-Assembly of Colloidal Particles"

Marjolein Dijkstra, Debye Institute for Nanomaterials Science, Utrecht University
- David Rittenhouse Laboratory, A8

In 1960, Feynman challenged us to think “from the bottom up” and to create new functional materials by directing and manipulating the arrangements of individual atoms ourselves. With recent advances in the synthesis…



Department Colloquium: "Characterizing Exoplanets: From Hot Jupiters to Super-Earths"

Ray Jayawardhana, Cornell University
- David Rittenhouse Laboratory, A8

Searches for exoplanets have revealed a remarkable diversity of worlds, and comparative studies of their properties have begun in earnest. Planets that transit are particularly well suited for atmosphere…



Primakoff Lecture: "Dark Matter, Neutron Stars, and Gravitational Waves"

Ann Nelson, University of Washington
David Rittenhouse Laboratory, A8

The recent observation of gravitational waves from merging neutron stars opens a new era for neutron star physics and astrophysics. I discuss the dark matter mystery and some of my work on
possible ways neutron…



Department Colloquium: Progress Toward a Solution of the “Supernova Problem”

Anthony Mezzacappa, University of Tennessee
- David Rittenhouse Laboratory, A8

The death of massive stars in core collapse supernova explosions are directly or indirectly responsible for the lion’s share of the elements in the periodic table, give birth to neutron stars and stellar mass black…
