Quantitative comparison of Anderson impurity solvers applied to transport in quantum dots
(2020-01-01)
We study the single impurity Anderson model (SIAM) using the equations of motion method (EOM), the non-crossing approximation (NCA), the one-crossing approximation (OCA), and Wilson's numerical renormalization group (NRG). ...
An efficient MHD equilibrium solver for control oriented transport models
(Elsevier Science SA, 2020-03)
In tokamak plasmas, the current density profile is a strong determiner of both MHD stability and confinement. The design of active control techniques for this profile relies on control oriented transport models that capture ...
An efficient impurity-solver for the dynamical mean field theory algorithm
(Instituto de Física de Líquidos y Sistemas Biológicos, 2017-08-01)
One of the most reliable and widely used methods to calculate electronic structure of strongly correlated models is the Dynamical Mean Field Theory (DMFT) developed over two decades ago. It is a non-perturbative algorithm ...
Análisis y simulación del modelo térmico y viscoso del proceso de Melt SpinningAnalysis and simulation of thermal / viscose model for Melt Spinning process
(Universidad Industrial de Santander, 2018-02)
El proceso de Melt Spinning es utilizado para la fabricación de cintas delgadas de materiales amorfos. El material se inyecta a través de una boquilla en estado líquido y se solidifica al entrar en contacto con una rueda ...
Numerical methods for nanoscopic systems based on density matrix renormalization
(American Scientific Publishers, 2008-12)
The Density Matrix Renormalization Group (DMRG) has become a powerful numerical method that can be applied to nanoscopic and low-dimensional strongly correlated fermionic and bosonic systems. It allows for a very precise ...
Solving the multi-site and multi-orbital Dynamical Mean Field Theory using Density Matrix Renormalization
(Frontiers Research Foundation, 2018-02)
We implement an efficient numerical method to calculate response functions of complex impurities based on the Density Matrix Renormalization Group (DMRG) and use it as the impurity-solver of the Dynamical Mean Field Theory ...
The vertex separator problem: algorithms and computations

Energy and exergy assessment in a perimeter cooled data center: the value of second law efficiency
(Elsevier, 2017)
The Data Center Industry remains in steady growth with worldwide energy consumptions in the order of hundreds of TWh, and yearly growth rates higher than the growth of global electricity consumption. Electronic cooling ...
