Biography

Dr. Kartik Samanta is an Assistant Professor (Grade-I) in the Department of Physics and Materials Science and Engineering (PMSE) at Jaypee Institute of Information Technology (JIIT), Noida, India. He received his M.Sc. in Physics (Silver Medallist) from IIT Guwahati in 2012 and his Ph.D. in Physics from the S. N. Bose National Centre for Basic Sciences, Kolkata, in 2017. Following his Ph.D., he pursued postdoctoral research at Forschungszentrum Jülich (PGI-1/IAS-1), Germany (2018-2021), and at the Max Planck Institute for Chemical Physics of Solids, Dresden, Germany (2021-2022). Before joining JIIT, he was a Post-Doctoral Research Associate at University of Nebraska-Lincoln, USA from 2023.

His research interests span a broad area of computational materials science and engineering, particularly inquantum spin transport, nanoscale magnetism, andtopological transport phenomena in nanoscale systems and devices. Methodologically, his work employs first-principles density-functional theory, many-body approaches, and non-equilibrium Green’s functions for transport. Current directions include antiferromagnetic tunnel junctions (AFMTJs), altermagnets, and chiral/topological Nernst effects aimed at next generation, ultrafast, energy-efficient non-volatile memory and thermoelectric devices. 

He has authored over 30 publicationsinhigh-impact international journals, including Nature, Advanced Materials, Nano Letters, ACS Nano, PNAS, JACS, npj Computational Materials, Physical Review B (Letters), and Communications Physics, and more and serves as a reviewer for journals including Nano Letters, Journal of Applied Physics, Physical Review B, Journal of Materials Chemistry C, and Materials Science in Semiconductor Processing. He has been actively collaborating with several world-renowned experimental research groups in the USA, Germany, France, Japan, the Netherlands, and India.

Research Highlights

Our work has advanced antiferromagnetic spintronics and topological transport. He co-led theory demonstrating that spin-split insulating antiferromagnets can act as efficient spin filters, offering an alternative to conventional spin-filter barriers and enabling AFM-based spintronic devices (Nano Letters, 2025). In collaboration with experimental teams, he contributed to the discovery of world’s first twist-assisted all-antiferromagnetic tunnel junctions in the atomic limit using 2D van der Waals CrSBr (Nature, 2024). His studies on magnetic tunnel junctions established routes to read out antiferromagnetic order parameters via asymmetric MTJ concepts and related spin-transport mechanisms (PRB, 2024).

Beyond MTJs, he has proposed/demonstrated oxide double-perovskites as fertile platforms for large anomalous Hall/Nernst responses and topological phases, guiding materials discovery via high-throughput first-principles computations (npj Comput. Mater., 2023). He helped uncover distinct “crystal” and “chiral” Hall effects (we term it) in collinear and canted magnets, respectively, enriching the taxonomy of transverse responses in magnetic systems (J. Appl. Phys., 2020; Communications Physics, 2021). His collaborative work further reported ideal Weyl semimetal behavior in EuCd2As2 and record-high room-temperature transverse thermoelectric signals in the kagome antiferromagnet YMn₆Sn₆, underscoring application potential in topological thermoelectrics (Advanced Science, 2023; Advanced Materials, 2022). Collectively, these results bridge symmetry-guided theory, quantum transport, and materials discovery toward energy-efficient spintronic and thermoelectric technologies.
