Optical Controlling of Thermal Parameters in a Nano-Body Containing Lithium Niobates Molecules
Thermal parameters including entropy, specific heat and thermal energy of a nanobody containing lithium niobates are theoretically investigated. When zero-index is present, these thermal quantities are controllable via the manipulation of optical parameters and geometry. Our exploration
is started from the calculation of the thermal parameters in the THz gap, whose wavelength is ranging from 30 μm to 3 mm. It can be noted that the value of the entropy and specific heat is increasing when the wavelength is increasing in this optical range. Furthermore, we investigate
its thermal behavior in the case of long wavelength, ranging from 3 mm to 650 m. It can be found that the variation of the entropy, the specific heat and the thermal energy from positive to negative, which indicates the transition from the thermal radiation to thermal absorption. Still, we
calculate the value of critical temperature associate with the zero-index, it can be seen that these values of the temperature is modulated by the combining of the optical parameter and the wavelength. Several transitions of the thermal energy from the positive value to negative value can
be seen. Our study shows potential and flexible application of optics in modulating the thermal quantities.
