Multicriticality in Yang-Lee edge singularity
Máté Lencsés, Alessio Miscioscia, Giuseppe Mussardo +1
In this paper we study the non-unitary deformations of the two-dimensional Tricritical Ising Model obtained by coupling its two spin Z2 odd operators to imaginary magnetic fields.…
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…
False vacuum decay in the 1+1 dimensional theory
Dávid Szász-Schagrin, Gábor Takács
The false vacuum is a metastable state that can occur in quantum field theory, and its decay was first studied semi-classically by Coleman. In this work we consider the 1+1 dimensi…
Confinement in the tricritical Ising model
M. Lencsés, G. Mussardo, G. Takács
We study the leading and sub-leading magnetic perturbations of the thermal integrable deformation of the tricritical Ising model. In the low-temperature phase, these magnetic…
