    Introduction In quantum field theory, vacuum energy is the zero-point energy of all the fields in space. This includes both the electromagnetic field and the other fundamental fields. It’s the lowest possible energy that a quantum mechanical physical system may have and is the energy of empty space. Zero-Point Energy The notion of vacuum energy…

    Introduction The Casimir Effect is a quantum mechanical phenomenon where two uncharged metallic plates attract each other when placed a few nanometers apart in a vacuum. It was first predicted by Dutch physicist Hendrik Casimir in 1948. Theory The Casimir effect arises due to the quantum fluctuations of the electromagnetic field in a vacuum. Even…
