Web13 de jul. de 2024 · The asymmetric quantum Rabi model (AQRM) has a broken $\\mathbb{Z}_2$ symmetry, with generally a non-degenerate eigenvalue spectrum. In some special cases where the asymmetric parameter is a multiple of the cavity frequency, stable level crossings typical of the $\\mathbb{Z}_2$-symmetric quantum Rabi model are … Web14 de abr. de 2024 · By evaluating the electrostatic model using Gauss’s law, we found that the above-mentioned two major experimental observations can be well reproduced, as …
WebThe open Dicke model The Dicke model of Eq 1 assumes that the cavity mode and the two-level systems are perfectly isolated from the external environment. In actual experiments, this assumption is not valid: the coupling to free modes of light can cause the loss of cavity photons and the decay of the two-level systems (i.e. dissipation channels). Web25 de ago. de 2024 · We also mention that the method of [20] for the computation of the hidden symmetry has been extended to treat other systems with bias terms (see [18] for the biased Dicke model and [19] for other ...
WebThe simplest realization of the Dicke model involves the dipole coupling between two-level atoms in a cavity. In this system, the observation of the superradiant transition is hindered by two possible problems: (1) The bare coupling between atoms and cavities is usually weak and insufficient to reach the critical value , see Eq. 6.
