Context: Scientists at Raman Research Institute (RRI), Bengaluru, have discovered a new method to detect topological invariants in quantum materials using spectral function.
About A New Method to Detect Topological Invariants in Quantum Materials:
• What is Spectral Function?
• The spectral function is a quantum tool that describes how energy and particles like electrons behave inside a material. It’s widely used to study electronic structure, such as density of states and dispersion relations.

• Developed By: Developed by Raman Research Institute (RRI), under the Department of Science and Technology.
• How It Works?
• The team analysed momentum-space spectral function (SPSF), which acts like a quantum fingerprint. SPSF maps how electrons distribute over energy and momentum, revealing hidden topological features.

• Key Features:
• Topology Detection: Unveils invariants like winding numbers (1D) and Chern numbers (2D). Non-Invasive Technique: Avoids complex physical manipulation or destructive probing. Faster and Accessible: Easier than traditional tools like ARPES (Angle-Resolved Photoemission Spectroscopy). Universal Application: Can be applied across different classes of topological materials. Quantum Insight: Provides deeper understanding of electron dynamics and material behaviour at the quantum level.
