Hermitian Hamiltonians are a fundamental concept in quantum mechanics, serving as the mathematical foundation for describing the energy and time evolution of quantum systems. They are named after the ...

Researchers say they have observed parity-time symmetry breaking for the first time in an experiment. The result was obtained using a “dilation” technique on a single-spin system – a nitrogen-vacancy ...

A research team proposes an efficient experimental platform for non-Hermitian physics research. When optical gain or loss are precisely controlled using nanophotonics, a new physical event called the ...

A PT-symmetric non-Hermitian photonic system composed of specifically designed metal structures is used to conduct arbitrary polarization transition from the equator and generate polarization vortices ...

What is Non-Hermitian Physics? Non-Hermitian physics is a rapidly growing field that deals with open quantum systems that exchange energy and information with their environment. Unlike closed systems ...

Researchers have detected the third-order exceptional line (EL) in a nitrogen-vacancy (NV) spin system and have methodically investigated the relationships between symmetries and high-order ...

A research team has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant advance in quantum physics research.

Research teams led by Academician DU Jiangfeng and Prof. RONG Xing from CAS Key Laboratory of Microscale Magnetic Resonance of University of Science and Technology of China (USTC) have systematically ...
