Non-Hermitian coupled cluster method for non-stationary systems and its interaction-picture reinterpretation

R. F. Bishop, M. Znojil

The interaction picture in a non-Hermitian realization is discussed in detail and considered for its practical use in many-body quantum physics. The resulting non-Hermitian interac…

Frustrated spin- $\frac{1}{2}$ Heisenberg magnet on a square-lattice bilayer: High-order study of the quantum critical behavior of the $J_{1}$ -- $J_{2}$ -- $J_{1}^{⊥}$ model

R. F. Bishop, P. H. Y. Li, O. Götze +1

The zero-temperature phase diagram of the spin- $\frac{1}{2}$ $J_{1}$ -- $J_{2}$ -- $J_{1}^{⊥}$ model on an $AA$ -stacked square-lattice bilayer is studied using the coupled cluster…
