Gutzwiller Renormalization Group
Nicola Lanatà, Yong-Xin Yao, Xiaoyu Deng +3
We develop a variational scheme called "Gutzwiller renormalization group" (GRG), which enables us to calculate the ground state of Anderson impurity models (AIM) with arbitrary num…

Finite-Temperature Gutzwiller Approximation from Time-Dependent Variational Principle
Nicola Lanatà, Xiaoyu Deng, Gabriel Kotliar
We develop an extension of the Gutzwiller approximation to finite temperatures based on the Dirac-Frenkel variational principle. Our method does not rely on any entropy inequality,…
