    Impact of electron-electron interactions on the thermoelectric efficiency of graphene quantum point contacts
    (Physical review B, 2022) Sánchez Ramírez, Irián; Baba, Yuriko Caterina; Chico Gómez, Leonor; Domínguez-Adame Acosta, Francisco
    Thermoelectric materials enable us to harness dissipated energy and make electronic devices less energydemanding. Heat-to-electricity conversion requires materials with a strongly suppressed thermal conductivity but still high electronic conduction. This goal is largely achieved with the help of nanostructured materials, even if the bulk counterpart is not highly efficient. In this work, we investigate how thermoelectric efficiency is enhanced by many-body effects in graphene nanoribbons at low temperature. To this end, starting from the Kane-Mele-Hubbard model within a mean-field approximation, we carry out an extensive numerical study of the impact of electron-electron interactions on the thermoelectric efficiency of graphene nanoribbons with armchair or zigzag edges. We consider two different regimes, namely trivial and topological insulators. We find that electron-electron interactions are crucial for the appearance of interference phenomena that give rise to an enhancement of the thermoelectric efficiency of the nanoribbons. Lastly, we also propose an experimental setup that would help to test the validity of our conclusions.

    Propuesta de una nueva metodología para la enseñanza de la física de la materia condensada: clase semipresencial con formato de taller
    (2022) Domínguez-Adame Acosta, Francisco; Díaz García, Elena; Chico Gómez, Leonor; Relaño Pérez, Armando; Díaz Fernández, Álvaro; Molina Fernández, Rafael Alejandro; Baba, Yuriko Caterina; López Corps, Ángel
    En este Proyecto INNOVA-Docencia hemos pretendido superar estas limitaciones académicas de las asignaturas tradicionales de grado y máster. Para ello, se ha llevado a cabo la implementación, el desarrollo y el análisis de resultados de la clase semipresencial con formato de taller, particularizada a la docencia de la FMC. Partimos del convencimiento de que este estudio es necesario incluso en el futuro, cuando la crisis sanitaria se haya superado. La UCM está haciendo ya un esfuerzo considerable para ofrecer cursos virtuales o que requieran poca presencialidad.
