Study reveals clues to nature of ultraluminous X-ray source

Scientists from the Raman Research Institute (RRI) have analysed rare, repeating bursts of energy from a distant ultraluminous X-ray source (ULX), offering new insights into the behaviour of some of the universe’s most extreme objects. The study focuses on ULX M74 X-1, located in the spiral galaxy M74, where astronomers observed irregular but recurring X-ray flares. These bursts, lasting around half an hour, show no fixed periodicity, making the source particularly intriguing. ULXs are syste...

New non-invasive technique offers window into the Quantum World by measuring atom density

Scientists at the Raman Research Institute (RRI), Bengaluru, have developed a novel, non-invasive technique to measure the local density of cold atoms in real time without significantly disturbing their quantum state - an advance that could accelerate progress in quantum computing, quantum sensing and precision measurement technologies. The method, known as Raman Driven Spin Noise Spectroscopy (RDSNS), overcomes key limitations of conventional atom-imaging techniques used in cold atom experimen...

Morning coffee inspires breakthrough in detecting toxic dyes in food and water

A phenomenon as simple as a coffee stain on a table may hold the key to detecting dangerous toxins in food and water at extremely low concentrations. Scientists at Raman Research Institute (RRI), supported by the Department of Science and Technology, Government of India, have developed a powerful and cost-effective technique that uses the coffee-stain effect to identify harmful dyes such as Rhodamine B at concentrations as low as one part per trillion. When a coffee droplet dries, it leaves a d...

New method developed to detect hidden properties in exotic materials

In a breakthrough that could boost research in next-generation technologies, scientists at the Raman Research Institute (RRI), Bengaluru, have developed a novel method to detect hidden quantum properties in exotic materials using a concept known as the spectral function. Topological materials, such as topological insulators and superconductors, are known for their unusual electronic behaviour. These materials are considered crucial for advancing quantum computing, fault-tolerant electronics...
