Solar System and Atomic Clock Bounds on Locally Coupled Swampland Scalars
Suraj Gavhale, Maxim Khlopov, Oem Trivedi +1
We study how local measurements constrain light scalar fields that are relevant in late time cosmic acceleration and are often discussed in connection with swampland criteria. Star…
