In this paper. we use the su(1. 1)-algebraic treatment to explore the effects of the intrinsic decoherence in a two-mode cavity containing a two-level atom. Each field is resonant with the qubit through a four-photon process. https://safeersappliancers.shop/product-category/zanussi-zcg63050wa-60cm-double-gas-cooker-with-electric-grill-white/
