He continues with approximation methods, perturbation theory, quanta in crystalline materials, various matrices, harmonic oscillators and photons, and fermions. Each chapter closes with a review of ...

To address this question, we develop a theoretical framework to analyze the quantum information spreading in many-body chaotic system. We build up the connection between quantum information spreading ...

These surface states are topologically protected, meaning they are robust against local perturbations and cannot be destroyed by impurities or defects. Topological insulators have potential ...

De Broglie waves, the Schroedinger equation, wave functions, wave packets, Heisenberguncertainty principle, expectation values, particle in a box, the simple harmonic oscillator, free particles, step ...

The topics include mathematical framework of complex vector spaces, exactly solvable systems such as harmonic oscillator and spin-half, path integral formalism, continuous and discrete symmetries, ...

Our findings show that while classical gravitational waves do not generate entanglement, the quantum version of these waves ...
