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…
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…
On Factorizable S-matrices, Generalized TTbar, and the Hagedorn Transition
Giancarlo Camilo, Thiago Fleury, Máté Lencsés +2
We study solutions of the Thermodynamic Bethe Ansatz equations for relativistic theories defined by the factorizable -matrix of an integrable QFT deformed by CDD factors. Such $…
Entanglement Dynamics after a Quench in Ising Field Theory: A Branch Point Twist Field Approach
Olalla A. Castro-Alvaredo, Máté Lencsés, István M. Szécsényi +1
We extend the branch point twist field approach for the calculation of entanglement entropies to time-dependent problems in 1+1-dimensional massive quantum field theories. We focus…
