This project aims at creating a group at Brazilian Synchrotron Light Laboratory (LNLS) to study new topological states of matter under extreme conditions. These topological materials are a new class of materials, which combines exotic physical properties, like huge magnetoresistance (MR), with a great potential for novel applications, such as highly efficient memory chips. Our group will explore the facilities of the new Brazilian synchrotron source (SIRIUS) that will be the largest and most complex scientific infrastructure ever built in Brazil, and will work in strong collaboration within the Max-Planck Institute for the Chemical Physics of Solids (MPI-CPfS). The association between the two the world-leading facilities, such as LNLS/SIRIUS and MPI-CPfS, will offer a unique opportunity to elucidate the correlation between electronic, structural and magnetic properties of topological materials and will create a group that will perform world-leading fundamental research on material science, working at the boundaries of condensed matter physics. Our main research interest will be to understand topological novel states of matter by experimental investigations at very low temperature and under high magnetic field and high pressure. Particularly, our aim is to understand the structural and electronic behavior of novel states of matter through state of art Synchrotron Radiation Techniques (SRT techniques. To achieve the scientific goals, we propose to establish new instrumentations to allow the realization of SRT experiments at low temperatures (down to 300 mK), high magnetic field (up to 11T), high hydrostatic pressure (up to 300 GPa) and under uniaxial (up to 1%) pressure at Sirius. In addition, we expect to develop conditions to realize the SRT experiments in combination with in situ transport experiments. The possibility of studying any material (magnetic, superconducting, geological, biological, among others) under extreme pressure, temperature and magnetic field with flexible instrumentation will be crucial for fostering a wide spectrum of research in materials science in the future synchrotron light source at LNLS.
