Physics strings theory
We also organize weekly seminars jointly with the Phenomenology Group.

Members of our group interact synergistically with other groups of the High Energy Physics program at UW-Madison. Since then, the scope of this research program has grown resulting in the formation of the Theoretical and Computational Cosmology Group and the AI ∩ Universe Initiative. The String Theory research program began as part of the University of Wisconsin Cluster Hiring Initiative on Mathematical Physics. The cluster and affiliated faculty cover the field from mathematical aspects of string theory to string cosmology and string phenomenology. This cluster focuses talents and resources of the UW-Madison mathematics and physics departments on this great endeavor of theoretical physics. This sparked an intense interaction between physicists and mathematicians that led to substantial contributions to both fields. The formulation of quantum gravity requires a similar change of physical and mathematical concepts as the development of quantum mechanics. As a consequence, black holes have been successfully treated as quantum objects and serious efforts are made toward a theory of quantum cosmology. String theory’s unification envisions that each particle in the standard model of particle physics is a different vibration of a single type of one-dimensional string. String dualities lead to non-perturbative formulations of gauge theory and quantum gravity. It regularizes quantum gravity, provides a perturbative expansion in the regime of small gravitational coupling, and unifies the gravitational force with the forces of the standard model of elementary particle physics.

String theory addresses one of the deepest problems of contemporary physics, namely the reconciliation of gravity and quantum theory.
