Kohima: Researchers from Nagaland University and IIT Bombay developed a new two-dimensional lattice structure. They call it the diamond-dodecagon lattice. The design could help experts control strange quantum states using magnetic fields. This work opens doors for quantum sensors, programmable devices, and advanced materials. The team published their findings in the peer-reviewed Journal of Physics: Condensed Matter under DOI 10.1088/1361-648X/ae9dd8.
Biplab Pal of Nagaland University and Joydeep Majhi of IIT Bombay led the study. Computer simulations prove the geometry traps electrons in small spots. This process produces three flat energy bands. These bands are vital because limited electron mobility leads to stronger interactions. These interactions often create unique quantum phenomena. A magnetic field can trigger a topological phase transition. The material then acts as an insulator inside but carries electricity along its edges. These edges resist certain imperfections.
Pal stated that the study uses lattice geometry to influence quantum behaviour. Majhi noted that specially designed structures force electron pathways to cancel out, which traps the particle. "The arrangement of atoms can confine electrons and create multiple flat bands, while an external magnetic field can tune these states and drive the system into a topological phase," said Pal. The project received funding from a Minor Start-up Research Grant from Nagaland University.
Nagaland University Vice-Chancellor Jagadish Kumar Patnaik praised the collaboration. He sees it as a move toward strengthening national quantum capabilities. The research is currently theoretical and simulation-based. Future steps include experimental reproduction using photonic lattices or ultracold atomic systems. The team will also look for new phases that work in real-world conditions.
