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 ...
Abstract Let A be an n × n Hermitian matrix and A = UΛUH be its spectral decomposition, where U is a unitary matrix of order n and Λ is a diagonal matrix. In this note we present the perturbation ...
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 ...
