A new approach to the Kondo effect: sophomore's dream function and Lee-Yang zeros
V. Yu. Irkhin
We develop an analytical approach to the Kondo problem based on an effective partition function that generalizes the sophomore's dream integral. The Kondo crossover is represented…

Locallized Magnetism in Low-Dimensional Systems
A. A. Katanin, V. Yu. Irkhin
The current theoretical and experimental situation is reviewed for low-dimensional (layered and chain-like) insulating systems. Such systems possess a low magnetic transition tempe…

Magnetic order and spin fluctuations in low-dimensional insulating systems
A A Katanin, V Yu Irkhin
The current theoretical and experimental situations are reviewed for low-dimensional insulating systems with a low magnetic transition temperature TM and pronounced short-range mag…
