نوسانگرهاي جفت شده به عنوان مدل انرژي تاريك كوئينتوم

Coupled oscillators as model of quintom dark energy

مدل نوسانگر های جفت شده به صورت مدلی برای انرژی تاریك در نظر گرفته شده است كه در آن فرض می شود جهان دارای مختصات خمیده فضایی بوده و مدل آن ... By assumption of a non-spatially flat FLRW universe, in addition to the need to understand quintom dynamics with general potential, the coupled oscillators are considered as models of quintom dark energy. We study a toy model for quintom cosmology recently introduced in the literature and consisting of three oscillators, one of which carries negative kinetic energy. The results are compared with the exact phase space picture obtained for similar dynamical systems.
