q-Deformed Tamm-Dancoff oscillators: Coherent state and thermostatistics

초록

The q-deformed bosonic Tamm-Dancoff oscillator algebra is considered. The coherent state of the q-deformed bosonic Tamm-Dancoff oscillator algebra is first constructed in detail. Second, the high-temperature thermostatistical properties of a gas of the Tamm-Dancoff oscillators are investigated. For high temperatures, the specific heat, the entropy and the equation of state for the system are derived in terms of the real deformation parameter q. The results obtained by the effects of Tamm-Dancoff type q-deformation show that they could be useful for further researches on understanding of mutual interactions between bosons and fermions in many-body quantum systems.
