In the previous researches, superradiant phase transition (SPT) controlled by interacting strength between two-level atom and photons has been a hot topic in Rabi model Rabi-dimer which describes two cavities coupled an inter-cavity hopping parameter. Moreover, SPT is found to be same universal class as that investigating correlation-length critical exponent. our research, we concern about whet...

The generated magnitude of quadrature squeezing in a cavity-coupled ensemble, which is continuously driven using coherent off-axis field, theoretically explored. Using truncated set equations-of-motion derived from Dicke Hamiltonian, steady-state the cavity field numerically calculated to approach limit -3 dB, while frequency-modulated approaches -14 absence pure-dephasing, and as function ense...

The dynamics of a fully three-dimensional lid-driven cubical cavity (3D-LDC) flow at several post-critical conditions, i.e., beyond the first bifurcation, are elucidated using both linear and nonlinear analyses. When Reynolds number is increased critical value, symmetry breaks down intermittently with subsequent gradual growth in spanwise inhomogeneity. This results crossflow as well pronounced...
