In field of topological insulators, the article "Nonlocal Transport Near Charge Neutrality Point in a Two-Dimensional Electron-Hole System” published in PRL 108, 226804 (2012) by Prof. Gusev, Prof. Levine and collaborators was selected for the Virtual Journal of Nanoscale Science and Technology.
O professor Ronaldo Rodrigues Pelá, do Departamento de Física do ITA, foi premiado na Conferência Internacional de Física de Semicondutores (ICPS) ocorrida de 29/07 a 03/08 no ETH em Zurique.
Bose-Einstein condensation occurs when a system of quantum-mechanical particles with integer spin or angular momentum is cooled to its ground state and forms a coherent state of identical particles. The Bose-Einstein condensate (BEC) occurs in systems that satisfy two requirements: bosonic behavior and number conservation. It is this second requirement that limits the prevalence of BEC systems in nature. BECs were first identified in dilute collections of laser-cooled cold atoms in 1995, leading to the Nobel Prize.
DFMT I.C. student Henrique Jose Correia Zanoli received an Honorable Mention Award in the 20º International Scientific Initiation Symposium of USP. The awarded study “Structural and electronic analysis of amino acids by semi-empirical quantum computational methods” was supervised by Profa. Helena M. Petrilli in the NANOMOL group and supported by FAPESP I.C. scholarship.
By the controlled addition of doping impurities, Prof. Renato Jardim and collaborators from EEL-USP, UNIFEI and UNICAMP developed a new family of superconductors with relatively high critical temperature. In a recent paper, the hexagonal structure stabilization of the Nb5Ge3 compound doped with carbon atoms was reported.

In the program for "Special Visiting Researcher", aimed to attract foreign researchers recognized internationally as leadership, DFMT will receive Profs. Jason S. Gardner (Indiana University) and Paul Koenraad (Eindhoven University of Technology).
Project 1. Geometrically Frustrated Pyrochlore Magnets
The second edition of the MS Meeting (November 21-22) celebrated the 50th anniversary of the LESBT - Laboratório de Estado Sólido e Baixas Temperaturas. The event program was centered in this laboratory history, pioneer in the development of low temperatures in Brazil, and filled by scientific lectures and historical keynotes given by DFMT members and invited speakers.
In the last weeks of January, a vibrating sample magnetometer - VSM was installed in the Laboratory of Magnetic Materials. This equipment, model 7404 from LakesShore is used to characterize the DC magnetic properties of materials as a function of magnetic field, temperature, and time.
