The first experimental observation of Dirac exceptional points
Exceptional points (EPs) are unique types of energy-level degeneracies that occur in non-Hermitian systems. Since their existence was first proposed more than a century ago, physicists have only been able to experimentally ...
New physics theory to study low-energy excitations in quantum quasicrystals
Quasicrystals, exotic states of matter characterized by an ordered structure with non-repeating spatial patterns, have been the focus of numerous recent physics studies due to their unique organization and resulting symmetries. ...
New quantum optics theory proposes that classical interference arises from bright and dark states of light
Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In contrast, quantum mechanics ...
Quantum sensors tested for next-generation particle physics experiments
To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of a variety of masses ...
