Nonperturbative real-space renormalization group scheme for the spin-1/2 XXX Heisenberg model
(AMER PHYSICAL SOC, 2001-11-01)In this paper we apply an analytical real-space renormalization group formulation which is based on numerical concepts of the density-matrix renormalization group, Within a rigorous mathematical framework we construct ... -
Towards the evaluation of the relevant degrees of freedom in nonlinear partial differential equations
(SPRINGER, 2002-03)We investigate an operator renormalization group method to extract and describe the relevant degrees of freedom in the evolution of partial differential equations. The proposed renormalization group approach is formulated ...
