What comprises a global symmetry of a Quantum Field Theory (QFT) has been vastly
expanded in the past 10 years to include not only symmetries acting on higher-dimensional …

We review applications of string theory to cosmology, from primordial times to the present-
day accelerated expansion. Starting with a brief overview of cosmology and string …

The recent result of the Dark Energy Spectroscopic Instrument (DESI) in combination with
other cosmological data shows evidence of the evolving dark energy parametrized by the w …

A bstract Motivated by principles from the Swampland program, which characterize
requirements for a consistent UV completion of quantum gravity, combined with …

These lecture notes provide a pedagogical introduction, with exercises, to the techniques
used in attempts to construct vacua with stabilized moduli in string theory. The reader is only …

A bstract We reconsider the problem of bounding higher derivative couplings in consistent
weakly coupled gravitational theories, starting from general assumptions about analyticity …

The swampland is the set of seemingly consistent low-energy effective field theories that
cannot be consistently coupled to quantum gravity. In this review we cover some of the …

A bstract In the Emergence Proposal in Quantum Gravity it is conjectured that all light-
particle kinetic terms are absent in the fundamental ultraviolet theory and are generated by …

A bstract The Swampland Distance Conjecture (SDC) states that, as we move towards an
infinite distance point in moduli space, a tower of states becomes exponentially light with the …

The species scale Λ s≤ M pl Λ_s≤M_\rmpl serves as a UV cutoff in the gravitational sector
of an EFT and can depend on the moduli of the theory as the spectrum of the theory varies. It …
