In a Kerr-nonlinear blackbody, bare photons with opposite wave vectors and helicities are bound into pairs and unpaired photons are transformed into a new kind of quasiparticle, the nonpolariton. The nonpolariton system constitutes free thermal radiation in the blackbody. In this paper, the...

We investigate a squeezed thermal spin state of nonlinear spin waves in Heisenberg ferromagnets. In this state, the magnon system possesses a new kind of quasiparticle, the dressed magnon, whose mass is a monotonically decreasing function of temperature. The noise of one spin component in the...

Within the framework of the theory of q-deformed bosons, we investigate Bose–Einstein condensation of a q-deformed boson system, which has finite particle number and is trapped in a harmonic potential trap, by using the approach of modified density of states. For such a trapped q-deformed...

We investigated the effects of poly(3, 4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) films treated with methoxyethanol (ME) on the performance of polymer solar cells, and the effects were compared with the PEDOT:PSS films treated with dimethyl sulfoxide (DMSO). In particular, a...

The self-organization of the polymer in solar cells based on regioregular poly(3-hexylthiophene)(RR-P3HT):[6, 6]-phenyl C61-butyric acid methyl ester is studied systematically as a function of the room temperature (RT) (varied from 300 K to 290 K). Optimal self-organized structures within the...

Greenhouse gas emission inventories are useful tools for monitoring air quality and assisting local policy development. This article estimates CO2 emission inventories from energy consumption and carbon intensities of provinces and municipalities in Mainland China in 1990, 1995, 2000, and...
