Quantum chaos refers to the phenomenon in quantum mechanics where classical stability in quantum systems is lost, leading to unpredictable behavior. Quantum mechanics is a fundamental theory in physics developed to explain phenomena that cannot be described by classical mechanics. Quantum chaos represents one of the significant phenomena in physics and constitutes a research field relevant to developments like quantum computing. The study of quantum chaos often involves analyzing spectral statistics using random matrix theory approaches, where researchers implement algorithms to calculate energy level spacing distributions and compare them with Poisson or Wigner-Dyson distributions through numerical simulations. Key computational methods include diagonalizing Hamiltonian matrices and applying Fourier transforms to study time evolution patterns, which help characterize chaotic behavior through indicators like the spectral form factor and out-of-time-order correlators.
