We analyze a version of the sine-Gordon model in which the strength of the cosine potential has a periodic dependence on time. This model can be considered as the continuum limit of the many-body generalization of the Kapitza pendulum. Based on the perturbed CFT point of view. we develop a truncated conformal space approach (TCSA) to investigate the Floquet quasienergy spectrum. https://medicalwarehouses.shop/product-category/oxygen-therapy/
