Tunneling from a Slowly Rolling Multifield Background Using Tadpole Subtraction
Masaki Yamada
We study semiclassical tunneling in scalar field theories with slowly evolving homogeneous backgrounds. We formulate the problem by combining tadpole subtraction with an adiabatic…

Formation and scaling of strings for global symmetry
Masaki Yamada
We numerically investigate networks of global strings with multi-string junctions in a scalar field model whose vacuum manifold is $\mathrm{PSU}(N)=\mathrm{SU}(N)/\m…
