Abstract: We study Ising Field Theory (the scaling limit of Ising model near the Curie critical point) in pure imaginary external magnetic field. We put particular emphasis on the detailed structure Here, we present a Lee-Yang theory of quantum phase transitions including a method to determine quantum critical points which readily can be implemented within the We describe all linear operators on spaces of multivariate polynomials preserving the property of being non-vanishing in open circular domains. This completes the multivariate

Lee-Yang zeros are not just a theoretical con-cept, but they can also be determined which appeared in Lee experimentally [50–54]. In recent years, applications of Lee-Yang theory have been

Now, by the positivity argument of Vafa and Witten and some extra bounds one can prove that Lee-Yang singularities do not really appear in vector-like gauge theories. Determining the phase diagram of interacting quantum many-body systems is an important task for a wide range of problems such as the understanding and design of quantum materials.
