  1. 2 lug 2024 · On Measuring Distances in the Quantum Gravity Landscape. Amineh Mohseni, Miguel Montero, Cumrun Vafa, Irene Valenzuela. In this note, we propose a generalized notion of distance between vacua in the theory of a scalar field ϕ with scalar potential V(ϕ) coupled to gravity.

  3. 12 lug 2024 · Later on, a better understanding of the theory and better calculational methods involved bringing in a large amount of new “math” to physics, especially the theory of unitary representations of groups. Yang-Mills theory: This was pretty much pure “math”: replacing a U (1) gauge theory by an SU (2) gauge theory.

    18 lug 2024 · In contrast to this example, the literature on the “swampland” phenomenon is currently dominated by informal hand-wavy arguments. Starting with Ooguri-Vafa 06 is an attempt to guess semi-precise rules-of-thumb for recognizing EFTs in the swampland, now known as the swampland conjectures.

  5. 12 lug 2024 · The swampland is Vafa’s program, and in different places he emphasizes different aspects of it. He is certainly not setting it up as an alternative to string theory. For what he has in mind, look at his original 2005 swampland paper

  6. 4 giorni fa · Demanding this `axion species scale' not to exceed the gravitational species scale, we obtain the bound (8\pi^2/g^2)f \lesssim M_ {\rm Pl} (8π2/g2)f ≲ M Pl. This is quite similar to the axion weak gravity conjecture bound, but can be applied to any gauge as well as the string interactions which are relevant to towers of states.

  7. 12 lug 2024 · We use freely acting asymmetric orbifolds of type IIB string theory to construct a class of theories in five dimensions with eight supercharges whose moduli spaces for vector multiplets and hypermultiplets can be determined exactly. We argue that no quantum corrections to these moduli spaces arise.
