New research discovers link between disparate approaches to quantum gravity

A new study by researchers from the International Centre for Theoretical Sciences (ICTS) and the Perimeter Institute for Theoretical Physics (PI) discovers a unifying thread in two approaches to quantum gravity that were previously believed to be separate. The study also elucidates a remarkable theoretical prediction: when both quantum mechanical and gravitational effects are important, it is impossible to confine information to a finite region [...]

Condition for Neutrino Oscillation Instability in Stars

Neutrinos are tiny elementary particles. These particles, which come in three flavors, have the unusual ability to periodically change their flavor from one to another via neutrino oscillations. Inside dense stars, the amplitude of these oscillations can grow exponentially with time. Scientists from TIFR Mumbai have discovered the condition for such instabilities. The research was published in Physical Review Letters.

Probing dark matter using gravitational waves

One of the biggest puzzles in modern cosmology is the existence of dark matter, which constitutes most of the matter in the universe. Recent research by an international team of researchers has used gravitational waves to probe the nature of dark matter. This work was published in the Astrophysical Journal Letters.

Engineering next generation solar powered batteries

Exploring new ways of storing solar energy is of high demand and it has been demonstrated that a lithium (Li) ion battery can be recharged directly using solar light. Modifications in the conventional two-electrode Li ion cell with a light entering window and a stable photoactive material as electrode are shown to be delivering an energy storage device where the solar energy can be directly harvested as chemical energy.
