A microscopic theory is one that contains an explanation at the atomic or subatomic level in contrast to a higher level or classical macroscopic or phenomenological theory. eg in superconductivity BCS theory is a microscopic theory.

Microscopic reversibility — The principle of Microscopic reversibility in physics and chemistry is twofold: First, it states that the microscopic detailed dynamics of particles and fields is time reversible because the microscopic equations of motion are symmetric with… … Wikipedia
BCS theory — is a microscopic theory of superconductivity, proposed by Bardeen, Cooper, and Schrieffer. It describes superconductivity as a microscopic effect caused by Bose condensation of pairs of electrons.HistoryBCS theory was developed in 1957 by John… … Wikipedia
Effective field theory — In physics, an effective field theory is an approximate theory (usually a quantum field theory) that includes appropriate degrees of freedom to describe physical phenomena occurring at a chosen length scale, while ignoring substructure and… … Wikipedia
