    "abstract": "Spontaneous emission can create coherences in a multilevel atom having close\nlying levels, subject to the condition that the atomic dipole matrix elements\nare non-orthogonal. This condition is rarely met in atomic systems. We report\nthe possibility of bypassing this condition and thereby creating coherences by\nletting the atom with orthogonal dipoles to interact with the vacuum of a\npre-selected polarized cavity mode rather than the free space vacuum. We derive\na master equation for the reduced density operator of a model four level atomic\nsystem, and obtain its analytical solution to describe the interference\neffects. We report the quantum beat structure in the populations.",
