Let's get to know about me !
Who am I ? & What I do ?
Myself, Sebin Joseph Sebastian, was born and brought up in Thiruvalla, Pathanamthitta, Kerala. I am a research scholar (integrated PhD student since 2018) and Prime Minister's Research Fellow (PMRF, December 2020 batch) in the School of Physics at IISER Thiruvananthapuram.
My work primarily focuses on "quantum magnetism" in low-dimensional and frustrated spin lattices. I have been doing my PhD under the supervision of Prof. Ramesh Chandra Nath since August 2020.
Research Interests
In the last ten years, experimentalists have become more interested in the interesting magnetic properties of frustrated spin systems, such as quantum spin liquids (QSL), classical spin-liquids, nematic phases, and so on. One of the main goals of our lab as we continue to study and make new 3d and 4f systems-based materials is to figure out how these ground states work in quantum systems that interact with each other. Several experimental methods are used to further describe the samples' structural, electrical, magnetic, and thermal characteristics.
Among these extensive categories, spatially anisotropic triangular lattice antiferromagnets are my focus of study. Because exchange interactions are competitive, these systems tend to form either a 1-D spin chain or a 2-D triangular lattice. This difference in exchange interaction makes the ground state features of this anisotropic triangular lattice an intriguing system to study.
