About

The Instituto de Ciencia de Materiales de Madrid (ICMM) is an institute of the Consejo Superior de Investigaciones Cientificas (CSIC) (Spanish National Research Council) founded in December 1986, that belongs to the Area of Science and Technology of Materials, one of the eight Areas in which the CSIC divides its research activities.

 

Our mission is to create new fundamental and applied knowledge in materials of high technological impact, their processing and their transfer to the productive sectors at local, national and European scales (the true value of materials is in their use), the training of new professionals, and the dissemination of the scientific knowledge.

Generation of a Nernst Current from the Conformal Anomaly in Dirac and Weyl Semimetals

M.N. Chernodub, Alberto Cortijo, and María A.H. Vozmediano

We show that a conformal anomaly in Weyl and Dirac semimetals generates a bulk electric current perpendicular to a temperature gradient and the direction of a background magnetic field. The associated conductivity of this novel contribution to the Nernst effect is fixed by a beta function associated with the electric charge renormalization in the material. We discuss the experimental feasibility of the proposed phenomenon.

The setup of the Nernst-Ettingshausen effect in open-circuit conditions. Voltage drops are induced by simultaneously applying an external magnetic field and a temperature gradient. Depending on whether the measured voltage is perpendicular (VT) or parallel to the gradient of T (VL)), we speak about Nernst or Nernst-Ettingshausen effects (see the details in the main text).
