Particles, Fields, Gravitation, and Cosmology

The goal of Dartmouth College Particles, Fields, Gravitation, and Cosmology Group is to understand the most basic laws of nature.  What are the laws of physics on the smallest scales? What is dark matter, and dark energy? What are the guiding principles that determine the structure and evolution of the Universe, from the earliest moments to the present day?

Theory Group


Robert Caldwell's research in theoretical cosmology includes: the theory of the origin and evolution of the large-scale structure of the Universe; the cosmic microwave background; gravitational waves and cosmology; quintessence, dark energy and the accelerating Universe.

Marcelo Gleiser's research on the physics of the early Universe lies at the interface of gravitation, particle physics and cosmology. Topics include gravitational radiation, inflationary cosmology, numerical and analytical studies of nonequilibrium classical and quantum fields, and the dynamics of phase transitions. 

Devin Walker's research focuses on understanding the underlying structure and composition of the Universe. Why is gravity so much weaker than the other forces of nature? What is the theory of dark matter? What is the origin of matter?
