de Sitter Space as a Glauber-Sudarshan State: II
Heliudson Bernardo, Suddhasattwa Brahma, Keshav Dasgupta +2
We provide further evidence to support the fact that a four-dimensional effective field theory description with de Sitter isometries in IIB string theory, overcoming the no-go and…
The four-dimensional null energy condition as a swampland conjecture
Heliudson Bernardo, Suddhasattwa Brahma, Keshav Dasgupta +2
We analyze four-dimensional Friedmann-Lemaitre-Robertson-Walker cosmologies in type IIB, arising from a M-theory dual, and find that the null energy condition (NEC) has to be obeye…
Purely non-perturbative AdS vacua and the swampland
Heliudson Bernardo, Suddhasattwa Brahma, Keshav Dasgupta +1
In recent times, a considerable effort has been dedicated to identify certain conditions -- the so-called swampland conjectures -- with an eye on identifying effective theories whi…
