Quantum tunneling and wave packets
WebNov 22, 2024 · Nov 22, 2024 at 7:00 AM. Why we need quantum fields, not just quantum particles. When we think of the quantum universe, we typically think about individual particles that also exhibit wave-like properties. But in truth, that's only part of the story; the particles aren't just quantum, but the fields and interactions between them are, too. http://www.softsea.com/review/Quantum-Tunneling-and-Wave-Packets.html
