DESCRIPTION:Title: A journey through the non-supersymmetric landscape\n\nA
 bstract: In this talk\, I will discuss my research on non supersymmetric t
 heories and anomalies. In particular\, I will revisit the chiral spectra o
 n charged 1- and 5-branes in the 10d non supersymmetric sp(16) string theo
 ry and verify anomaly cancellation via inflow. Furthermore\, I will show c
 ompelling evidence that the global structure of the gauge group is Sp(16)/
 Z2 along with hints of a possible duality to a non-supersymmetric heteroti
 c theory. Secondly\, I will discuss the presence of a discrete topological
  term in heterotic strings and delve into its relation with anomaly inflow
  cancellation on the worldvolume of the non-supersymmetric NS5-brane. Thes
 e insights will allow us to assess the consistency of candidate spectra fo
 r the six-dimensional theory living on these defects. Finally I will prese
 nt a recent study of Type II non-supersymmetric toroidal asymmetric orbifo
 lds with a vanishing cosmological constant at one-loop in string perturbat
 ion theory. This talk will be based on 2412.17894\, 2507.11610 and 2602.07
 113.
