Real Space Renormalization Group Techniques and Applications
Javier Rodriguez-Laguna
Real Space Renormalization Group (RSRG) techniques and their applications, mainly to quantum mechanics and to partial differential equations, are discussed. Special emphasis is giv…
Anderson transition in low-dimensional disordered systems driven by nonrandom long-range hopping
A. Rodriguez, V. A. Malyshev, G. Sierra +3
The single-parameter scaling hypothesis predicts the absence of delocalized states for noninteracting quasiparticles in low-dimensional disordered systems. We show analytically and…
Absence of weak localization in two-dimensional disordered Frenkel lattices
A. Rodriguez, M. A. Martin-Delgado, J. Rodriguez-Laguna +4
The standard one-parameter scaling theory predicts that all eigenstates in two-dimensional random lattices are weakly localized. We show that this claim fails in two-dimensional di…
Towards the Evaluation of the Relevant Degrees of Freedom in Nonlinear Partial Differential Equations
Andreas Degenhard, Javier Rodriguez-Laguna
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 ren…
A Density Matrix Renormalization Group study of Excitons in Dendrimers
M. A. Martin-Delgado, J. Rodriguez-Laguna, G. Sierra
We introduce the density matrix renormalization group (DMRG) method as an efficient computational tool for one-exciton approximations with off-diagonal disorder. This method allows…
A Real-Space Discrete Inverse Renormalization Group Method
Javier Rodriguez-Laguna
A numerical real-space version of the Inverse Renormalization Group proposed by Gawedzky et al is developed. It has been tested to obtain the scaling behaviour of the random-forced…
