WebJan 1, 2016 · Abstract. In this chapter we describe the fundamental aspects of bound-state quantum electrodynamics (BSQED). We recall the principal features of the Dirac equation. Then we describe quantum electrodynamics as a field theory. We provide the basic elements about representations, evolution operators and the S matrix. WebQuantum mechanics is in a position similar to that of relativity a hundred years ago. The Lorentz equations worked in 1905 but no one knew why. Then Einstein came along and …

WebApr 11, 2024 · Quantum mechanics; Get e-Alerts. Abstract. On-chip light sources are an essential component of scalable photonic integrated circuits (PICs), and coupling between light sources and waveguides has attracted a great deal of attention. Photonic waveguides based on bound states in the continuum (BICs) allow optical confinement in a low … WebThe quantum states for systems involving confining potentials have associated both quantized wavefunctions and energies. In other words, for such systems all the allowed quantum states are bound states. Note A confining potential, such as the harmonic oscillator or the infinite barrier, satisfies that V(x) → ∞ for x → ± ∞.
