Quantum Mechanics and Non-Hermitian Physics
Quantum Mechanics and Non-Hermitian Physics is a research topic within Atomic and Molecular Physics, and Optics. Science Explorer counts 19k research works in it since 1950. 18.1% of them reached the world's top 10% most cited for their field and year.
This cluster of papers explores the concept of Parity-Time (PT) symmetry in optics and quantum mechanics, focusing on non-Hermitian physics, exceptional points, topological phases, and nonlinear systems. It investigates phenomena such as PT-symmetric optical lattices, exceptional points in photonics, and the implications of PT symmetry for quantum mechanics and optical devices.

Which countries lead Quantum Mechanics and Non-Hermitian Physics research?
By volume, China and the United States publish the most (853 and 290 works in 2022–2025).
How concentrated that is
The same countries as shares of everything the list above accounts for. A node where two countries do two thirds of the work and one spread evenly across twelve read alike as a ranking and not at all alike here.
