SCALE-UP is developed by researchers from the University of Catabria (UC, Spain) and the Luxembourg Institute of Science and Technology (LIST), as well as by a number of collaborators.

The permanent UC and LIST researchers behind SCALE-UP, who constitute the core team of the project, are:

Pablo García-Fernández

CITIMAC Department, University of Catabria (Spain)

garciapa@unican.es

A quantum chemist by training, PGF is our expert in the tight-binding methods that are (albeit revised) at the core of how SCALE-UP models electronic structure. Complex effects in ferroic nano-structures are among his current research interests.

Jorge Íñiguez

Luxembourg Institute of Science and Technology

jorge.iniguez@list.lu

A condensed-matter theorist whose main focus is on ferroelectrics and multiferroics, JI has worked much on coarse-grained model potentials to describe materials undergoing soft-mode-driven structural transitions, which are the precursors of the lattice models implemented in SCALE-UP.

Javier Junquera

CITIMAC Department, University of Catabria (Spain)

javier.junquera@unican.es

Yet another condensed-matter theorist working on ferroelectrics, and the only member of the SCALE-UP team with prior experience in the development of an actual ambitious first-principles simulation code (SIESTA).

Other major contributor(s), currently active:

Carlos Escorihuela-Sayalero

carlos.escorihuela@list.lu

A PhD student at LIST lucky (unlucky?) enough to spend most of his days working on SCALE-UP. In fact, CES is the physicist-mathematician responsible for the (very efficient) way in which we construct lattice models in SCALE-UP now.

Finally, from the pre-history of the code (quite literally, as SCALE-UP did not exist back then):

Mathias P. Ljungberg

MPL worked on SPLD (“Second-Principles Lattice Dynamics”, an MIT-licensed code from which SCALE-UP inherits most of its lattice part) while being a post-doc at the Institute of Materials Science of Barcelona (ICMAB-CSIC). Some of the most ancient parts of the code were either written by him or benefited from his invaluable inputs.

Jacek C. Wojdeł

JCW wrote around 99 % of the lines of SPLD during his post-doc years at ICMAB-CSIC, and he may have invented the term “second principles”. What can we say? Any SCALE-UP user should be forever grateful to this gentleman !
