Fisher's zeros as boundary of RG flows in complex coupling space
A. Bazavov, A. Denbleyker, Daping Du +3
We discuss the possibility of extending the RG flows to complex coupling spaces. We argue that the Fisher's zeros are located at the boundary of the complex basin of attraction of…

Fisher's zeros as boundary of renormalization group flows in complex coupling spaces
A. Denbleyker, Daping Du, Yuzhi Liu +2
We propose new methods to extend the renormalization group transformation to complex coupling spaces. We argue that the Fisher's zeros are located at the boundary of the complex ba…
