Hidden Critical Points in the Two-Dimensional model: Exact Numerical Study of a Complex Conformal Field Theory
Arijit Haldar, Omid Tavakol, Han Ma +1
The presence of nearby conformal field theories (CFTs) hidden in the complex plane of the tuning parameter was recently proposed as an elegant explanation for the ubiquity of "weak…

Dynamical mean-field theory for Rényi entanglement entropy and mutual Information in Hubbard Model
Surajit Bera, Arijit Haldar, Sumilan Banerjee
Quantum entanglement, lacking any classical counterpart, provides a fundamental new route to characterize the quantum nature of many-body states. In this work, we discuss an implem…
