A team of physicists and engineers has demonstrated an optical device that filters two particles of light (or photons) based on the correlations between their polarisation that are only allowed in the ...

While usual gapless points that are not geometrically defective i.e. Dirac points (Left column) possess only eigenvalues within [0, 1] (Bottom Left), defective exceptional points (Right column) also ...

The interplay between quantum phase transitions and measurement-induced dynamics has emerged as a vibrant research frontier, uniting concepts from many-body quantum physics, quantum information theory ...
