This study presents the coherent and dissipative coupling realized in hybrid photonic resonators that have been achieved via constructive destructive interference of resonator fields with radiation a common transmission line fed microwave photons. In regime we found coexistence peculiar phenomenon bound state continuum (BIC) near crossing frequency uncoupled by satisfying Friedrich-Wintgen BICs condition. Again just rotating one samples dynamic adjustment parameter induced transparency...
Abstract The role of optical nonlinearity in light propagation through two different 1D open QED lattices is investigated, namely a chain qubits with direct coupling between the nearest neighbors and connected resonators to each which qubit side‐coupled. Using more accurate truncated Heisenberg‐Langevin equations method, reduction transmission increasing intensity these shown due effective photon–photon interactions related photon blockade mediated by qubits.

The Finite Difference Time Domain method (FDTD) uses centre-difference representations of the continuous partial differential equations to create iterative numerical models wave propagation. First we study propagation behavior in single dimension without PML and second part absorption using for same MATLAB environment.
ABSTRACT A modeling study was conducted with the objective of investigating effects perforation design and size consistency on treatment allocation in multicluster limited entry treatments. The numerical model couples an advanced wellbore flow simulator a well-established fracture simulator, which enables realistic complex designs pumping schedules. demonstrates that low variability hole dimension among perforations is important prerequisite for optimization uniformity. Variation initial...

Controlled transitions between coupling induced transparency (CIT) and absorption (CIA) are effects of both fundamental importance as well potential applications in various devices. We have explored these peculiar phenomena multi-mode coupled hybrid quantum systems by considering a tunable mode (TM) several static modes (SMs). The individual SMs TM designed such that they show CIA, but upon different we observe transition from CIA to CIT. Quite remarkably able achieve CIT using only purely...
Hybrid magnonics, exploring the coupling between magnons and quantum systems, is an exciting field for developing next-generation information technologies.
