  Environment induced steady state quantum coherence (SSQC) is a captivating
phenomenon that challenges conventional understandings of decoherence. In this
letter, we delve into the foundational aspects of environment-induced SSQC,
shedding light on its emergence within the framework of system-bath
interactions. Starting from a microscopic system-bath coupled model, we
investigate the dependence of SSQC on environmental memory effects, bath
temperature, system-bath coupling strength, and squeezing parameters. Our
findings reveal that the environment not only acts as a generator but also as a
disruptor of SSQC. A peak will exist for a non-Markovian bath, which is a
result of competition between these two mechanisms. Interestingly, the peak
disappears in Markovian case. Additionally, we observe that the generated SSQC
can be further amplified through environment squeezing.
