Fellow: Awarded 2010
Field of Study: Physical Sciences

Competition: Latin America & Caribbean

Education: Universidad de Buenos Aires, CONICET

Liliana Arrachea obtained the degree of Ms.C. (Licenciada) in 1990 and the Ph.D. in Physics in 1995 at Universidad de La Plata, Argentina. She did part of her Ph.D. research at Centro Atómico Bariloche, Argentina. In 1996-1998 she was Alexander von Humboldt Fellow at the Freie Universität Berlin and at the Max-Planck-Institute für Physik komplexer Systeme (MPIPKS), Dresden. In 1998 she was an invited professor at PUC-Rio de Janeiro, Brazil, and in 1999 she obtained a Researcher position from CONICET, Argentina, to work at Universidad de Buenos Aires. Since then, she has been a visiting scientist at the Scuola Internazionale Superiore di Studi Avanzati, Trieste, Italy, she received a second invitation from the Alexander von Humboldt foundation to work at the MPIPKS-Dresden, and she was Ramón y Cajal Researcher at Universidad de Zaragoza, Spain, until 2008.

Currently, she is an Independent Researcher of CONICET and Professor at the Universidad de Buenos Aires and Universidad Nacional de La Plata, Argentina. Her research area is condensed matter theory and she has expertise in field-theoretical techniques as well as in numerical methods. During her career, she has visited and given talks in several institutes of Argentina, Spain, Germany, France, Italy, and Switzerland. She has established collaborations with colleagues of several institutions of Argentina, Spain, Italy, France, Germany, USA, Ukraine, Switzerland, and Brazil. She has been as well a short-term Visiting Professor at University Paris 6 and Boston University and invited speaker in several international conferences. She is reviewer of several specialized journals, agencies of Argentina and the National Science Foundation.

Since receiving her Ph.D., her research has been centered in the study of models of strongly correlated electrons related to high-critical temperature superconducting materials. More recently, she also became interested in quantum transport in mesoscopic systems and nanostructures. Among her main achievements, she has proposed with collaborators analytical solutions to models of strongly correlated electrons published in Physical Review Letters 73, 2240 (1994) and 76, 4396 (1996). In the last ten years she has published several relevant contributions in the field of time-dependent quantum transport, including a book chapter. These works are products of her search for novel mechanisms for generating currents by recourse to time-dependent voltages in small size circuits. In particular, she has proposed a theoretical scheme to study these phenomena, which has been published in Physical Review B 72, 125349 (2005). In Physical Review B 75, 245420 (2007), she and collaborators established the principles of quantum refrigeration. During her Guggenheim Fellowship term, she will continue working along this research line.
