Unraveling Quantum Enigmas: From Unconventional Superconductivity to Kagome-Based Materials in Ta2V3.1Si0.9
Abstract: Ta2V3.1Si0.9 compound features a layered hexagonal structure with a prominent kagome plane pri- marily composed of vanadium atoms, hinting at intriguing atomic interactions. It exhibits mod- erately coupled superconductivity, defying BCS theory with a critical temperature of 7.5 Kelvin. Further exploration uncovers an unexpectedly large upper critical field and unique spin paramag- netic effects, pointing towards unconventional superconductivity mechanisms. Spin-orbit scattering provides clues to a delicate interplay of fundamental forces, expanding our understanding of super- conductivity. DFT calculations reveal a crucial Van Hove singularity band associated with V-dyz states, shedding light on electronic behavior. In-plane vibrations of vanadium atoms play a crucial role in the superconducting behavior, adding an unexpected layer of complexity. Our objective is to conduct Zero-Field (ZF) and Transverse Field (TF) Muon Spin Relaxation/Rotation (?SR) experi- ments to unveil the final secrets of Ta2V3.1Si0.9. This research not only redefines our understanding of superconductivity but also paves the way for exploring kagome-based materials, offering potential insights into nontrivial band structures and quantum phenomena. The future holds promise for uncovering the mysteries of the quantum world.
