    Introduction In the field of superconductivity, Cooper pairs play a fundamental role. Named after physicist Leon Cooper, a Cooper pair is a bound state of two electrons (or other fermions) with opposite momenta (i.e., moving in opposite directions) and opposite spins, effectively forming a boson. Formation of Cooper Pairs Electrons in a material are usually…

    Introduction The Josephson Effect is a quantum mechanical phenomenon involving pairs of superconductors separated by a thin insulating barrier, known as a Josephson junction. This effect, named after the British physicist Brian D. Josephson, who predicted it in 1962, allows for the tunneling of Cooper pairs across the barrier, leading to a supercurrent. Basics of…
