Cosmology and Field Theory

The language of field theory is not limited to particle physics. Recent advances in cosmology have allowed us to build accurate field theory descriptions of virtually every stage of our Universe's evolution: describing inflation in the early Universe, the subsequent growth of large scale structures, and the late-time domination of dark energy. Not only does this allow forecasting for a number of current and upcoming experiments and a wealth of new data, but it has also taught us important lessons about how to construct field theories under diverse conditions. From dealing with non-renormalizablity and non-local operators, to spontaneously breaking spacetime symmetries like translations and boosts, cosmology is a playground in which to test some of the most advanced field theory techniques around.

Black holes and quantum gravity

One of the most distinguishing features of gravity is its property of "UV/IR mixing" -- high energies means big lengthscales, and not small as usual in QFT. The most prominent avatar of this are black holes. In this talk I will introduce the concept of UV/IR mixing and move on to review the basic, universal aspects of black hole physics, their entropy and evaporation process, leading to the simplest version of the information "paradox". Along the way I will illustrate how each of these points are understood in String Theory / holography. Due to UV/IR mixing, black hole evaporation gedankenexperiments lead to universal properties any Einsteinian quantum theory of gravity, a research direction widely described as the "Swampland". I will describe two simple examples of these (absence of global symmetries in quantum gravity, and the Weak Gravity Conjecture) and give a rough overview of this developing subject.

Holography and its applications

The AdS/CFT correspondence, or more simply holography, is a conjectured duality between two very different theories. One is a theory of gravity with a negative cosmological constant and the other is a (conformal) quantum field theory in one dimension less, where gravitational forces are absent. Knowing the dictionary between the two, allows us to translate difficult, intractable problems of one side to simple computations in the other and potentially try to address some of the longstanding questions such as what is inside a black hole and how is the information loss paradox resolved. I will give a pedagogical review of the correspondence, highlighting some of the key results which brought it to be a very prominent field of research in the past 20 years and overviewing some of the resent research progress.

Reception

We are happy to invite all participants of the conference to a reception in the foyer of the MPP on Monday, April 1st, 18:00. The reception is made possibly by a sponsorship from the general consulate of the Kingdom of The Netherlands in Munich. The reception will be opened in the MPP lecture hall with a welcome speech by consul-general Paul IJmkers.

Conference Dinner

The conference dinner will take place on Tuesday, April 2nd, 19:00 at Aumeister, located within walking distance from the conference venue in the English garden. If you did not indicate your participation in the dinner during the registration process but still wish to participate please contact the organisers, as space is limited.
