ProjectsEigenstates of the Lewis-Riesenfeld invariant for de Sitter and quasi-de Sitter universes
Abstract Motivated from considerations in theoretical cosmology about fluctuations in the very early universe, the aim of the project was to investigate the spectrum of the Lewis-Riesenfeld invariant, an invariant of the time-dependent harmonic oscillator Hamiltonian, and to analyse the behaviour of its two lowest eigenstates in position representation. Scientific background The nature of the […]Abstract Motivated from considerations in theoretical cosmology about fluctuations in the very early universe, the aim of the project was to investigate the spectrum of the Lewis-Riesenfeld invariant, an invariant of the time-dependent harmonic oscillator Hamiltonian, and to analyse the behaviour of its two lowest eigenstates in position representation.
