Brief CV

Luis Foa TorresLuis E. F. Foa Torres (b. 1978) is a condensed matter physicist. He is a Professor of Physics at the University of Chile (FCFM). Before he worked in Argentina as a CONICET Independent Research Scientist; in Germany as a fellow of the Alexander von Humboldt Foundation (TU Dresden); in France, at CEA-Grenoble; and in Italy, at the Abdus Salam International Centre for Theoretical Physics, first as a postdoctoral fellow, then as Junior Associate of the Condensed Matter Section (2011-2016) and, more recently, and as a Simons' Associate of the Condensed Matter Section of ICTP (2020-present). He was awarded the ICTP Prize in 2018 in recognition of his work.

His research is focused on quantum transport, two-dimensional materials (e.g. graphene), topological insulators and the physics of driven systems. Inelastic effects deriving from electron-phonon and electron-photon interactions (e. g. quantum pumping, Floquet topological states) occupy a central stage in his contributions. He has more than 70 publications in international journals and a book published by Cambridge University Press. These works have collected more than 4200 citations with h-index 30. He has delivered more than 50 invited/plenary talks at international conferences/workshops and meetings and serves as referee for numerous journals and funding institutions including the European Research Council, Agence Nationale de la Recherche (France) and the National Science Foundation (US). He has been listed as outstanding referee of the American Physical Society and since 2022 serves as an Editorial Board member of Physical Review Letters (Condensed Matter Physics).

Main scientific achievements and appraisal of our research

My works combine insights in condensed matter concepts, technology driven goals and sheer curiosity. My main scientific achievements include:

  • Prediction of anomalous localization in non-Hermitian systems [V. M. Martinez-Alvarez et al., Physical Review B 97, 121401(R) (2018)], whereby a pristine non-Hermitian lattice may become devoid of extended states. This effect was called later on non-Hermitian skin effect by other authors and has been verified in experiments involving transcending condensed matter including mechanical systems, a quantum walk with photons, topoelectrical circuits and also in active matter (click for more information).This article together with another one in the same line [V. M. Martinez-Alvarez et al., Eur. Phys. J. Special Topics 227, 1295 (2018)] are placed among the top 1 per cent of the Physics literature according to Web of Science. The first one has also been listed as the fourth (out of 10.127) most cited items of Physical Review B (source: InCites Journal Citation Reports released in 2021).
  • Elucidating laser-induced chiral edge states in graphene [Perez-Piskunow et al. Physical Review B 89, 121401(R) (2014); Usaj et al. Physical Review B 90, 115423 (2014)] as well as their Hall response [Foa Torres et al. Physical Review Letters 113, 266801 (2014)].  The Hall response of laser-illuminated graphene has been experimentally observed in McIver et al. Nature Physics 16, 38-41 (2020).Two of these papers made half of the core highly cited papers in an emerging research front reported by Thomson Reuters (Periodically driven systems, 2017) and are within the top 1 percent of the Physics literature published around the same time.
  • Prediction of tunable laser-induced bandgaps in graphene using mid-infrared lasers [Calvo et al. Applied Physics Letters 98, 232103 (2011)]. The same physics was later observed at the surface of a topological insulator [Wang et al. Science 342, 453 (2013)].
  • Prediction of a Peierls-like mechanism in carbon nanotubes at high bias. [Foa Torres and Roche, Physical Review Letters 97, 076804 (2006)]. Still without experimental confirmation.
  • Elucidating the role of time-dependent fields in quantum charge pumping (the generation of a current at zero bias) with a single time-dependent gate voltage [Foa Torres, Physical Review B 72, 245339 (2005)]. Experiments on single-parameter pumps came later in 2008 [PRB 77, 153301 (2008)] holding great promise either in metrology or for new devices operating at the quantum limit.
  • A proposal for the electrical generation of coherent ultrasound by electrical means in semiconductors, i.e. a phonon laser [Foa Torres et al. Physical Review B 64, 193304 (2001); Camps et al. Physical Review B 64, 125311 (2001)]. This kind of devices was first demonstrated experimentally almost a decade later (see also http://physics.aps.org/articles/v3/16).

The first edition of the book “Introduction to Graphene-Based Nanomaterials” has been reviewed and positively appraised by Riichiro Saito (Tohoku University) and Mildred Dresselhaus (MIT, Kavli Prize winner 2012).

The accumulated citations of all the articles have been marked within the top two percent worldwide for the three latest yearly editions (2020,2021 and 2022) according to a bibliometric study.
