Variations on vacuum decay: the scaling Ising and tricritical Ising field theories
M. Lencsés, G. Mussardo, G. Takács
We study the decay of the false vacuum in the scaling Ising and tricritical Ising field theories using the Truncated Conformal Space Approach and compare the numerical results to t…
