摘要: The goal of this work is to show how the thermospin polarization current in a quantum ring changes presence Rashba spin-orbit coupling and quantized single photon mode cavity placed in. Employing reduced density operator general master equation formalism, we find that both interaction field can significantly modulate spin current. Tuning constant, degenerate energy levels are formed corresponding Aharonov-Casher destructive phase interference system. Our analysis indicates maximum be observed at points due accumulation system without field. thus suppressed. In cavity, leads an additional kinetic momentum electron. As result enhanced by
