Efficient computation of optical excitations in two-dimensional materials with the Xatu code
Autor: Uría-Álvarez, Alejandro José, Esteve-Paredes, Juan José, García-Blázquez, Manuel Antonio, Palacios, Juan José
Here we describe an efficient numerical implementation of the Bethe-Salpeter equation to obtain the excitonic spectrum of semiconductors. This is done on the electronic structure calculated either at the simplest tight-binding level or through densit

Publikováno v: J. Chem. Theory Comput. 19, 333 (2023)
In this manuscript we present a theoretical framework and its numerical implementation to simulate the out-of-equilibrium electron dynamics induced by the interaction of ultrashort laser pulses in condensed-matter systems. Our approach is based on ev

Girth Welding of Internally Clad API 5L Grade X65 Pipes using Low Alloy Steel Filler Metal
Autor: Alvarez, Alejandro
This study focuses on the development of low alloy steel (LAS) girth welds on internally clad API 5L Grade X65 steel by investigating the metallurgical phenomena of welds made using a high melting temperature consumable over a low melting temperature

Deep learning for disordered topological insulators through entanglement spectrum
Autor: Uría-Álvarez, Alejandro José, Molpeceres-Mingo, Daniel, Palacios, Juan José
Calculation of topological invariants for crystalline systems is well understood in reciprocal space, allowing for the topological classification of a wide spectrum of materials. In this work, we present a new technique based on the entanglement spec
