👉 Condensedness is a concept in quantum mechanics, particularly within the context of the Schrödinger equation. It refers to a phenomenon where certain quantum systems exhibit a reduced number or state of energy compared to their original state. Quantum states are described by wavefunctions that can be expanded into multiple eigenstates, which correspond to different energies and angular momenta. In the Schrödinger equation, a particle's wavefunction evolves according to the time-dependent Schrödinger equation: \[ \
