Entanglement: A Modern Aspect of Nature

Abstract

The intention of this paper is to provide an easy to understand introduction to the peculiarities of entangled systems. A novel description for strong (mass entanglement) and weak (spin-or-bital and thermal entanglement) quantum entangled particles is discussed and applied to the phenomena of superconductivity, superfluidity and ultracold gases. A brief statement about how to represent the physical reality of quantum-entanglement as Quantum-Field-Theory (QFT) is noted.
