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 ...

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.

Non-zero energy exchange with the environment can transform originally Hermitian systems into non-Hermitian ones. Beyond introducing complexity into the energy spectrum, non-Hermiticity can also ...

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 ...

Researchers from the Hong Kong University of Science and Technology, Xiangtan University and Southern University of Science and Technology recently unveiled a possible connection between catastrophe ...

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 ...
