Relaxion Monodromy and the Weak Gravity Conjecture
Luis E. Ibanez, Miguel Montero, Angel Uranga +1
The recently proposed relaxion models require extremely large trans-Planckian axion excursions as well as a potential explicitly violating the axion shift symmetry. The latter prop…
Closed tachyon solitons in type II string theory
Iñaki García-Etxebarria, Miguel Montero, Angel M. Uranga
Type II theories can be described as the endpoint of closed string tachyon condensation in certain orbifolds of supercritical type 0 theories. In this paper, we study solitons of t…
Transplanckian axions !?
Miguel Montero, Angel M. Uranga, Irene Valenzuela
We discuss quantum gravitational effects in Einstein theory coupled to periodic axion scalars to analyze the viability of several proposals to achieve superplanckian axion periods…
