-symmetric cavity magnomechanics with gain-assisted transparency and amplification
Cham Oumie, Wu-Ming Liu, Kashif Ammar Yasir
We investigate magnomechanically induced transparency in a parity-time-symmetric cavity magnomechanical system with traveling-field-induced non-Hermiticity. The setup consists of a…
Spectroscopic readout of chiral photonic topology in a single-cavity spin-orbit-coupled Bose-Einstein condensate
Kashif Ammar Yasir, Gao Xianlong
Topological photonic phases are typically identified through band reconstruction, steady-state transmission, or real-space imaging of edge modes. In this work, we present a framewo…
-Symmetry induced Bi-Stability in Non-Hermitian Cavity Magnomechanics
Chaoyi Lai, Shah Fahad, Kashif Ammar Yasir
We study the steady-state non-Hermitian magnomechanical system driven by a transverse magnetic field directly interacting with YIG sphere and excites cavity magnons and photons. To…
Symmetric Non-Hermitian Cavity Magnomechanics
Yu Chengyong, Kashif Ammar Yasir
We design and explore PT-symmetric behavior of a hybrid non-Hermitian cavity magnomechanics consisting of a ferromagnetic YIG sphere driven by external magnetic field. Non-Hermicit…
Engineering chaos in a four-mirror cavity-optomechanics with mechanical drives
Kashif Ammar Yasir, Gao Xianlong
We study occurrence of chaos in a four-mirror optomechanical cavity with mechanical drives externally interacting with two transversely located moving-end mirrors of the cavity. Th…
Controlled Electromagnetically Induced Transparency and Fano Resonances in Hybrid BEC-Optomechanics
Kashif Ammar Yasir, Wu-Ming Liu
We investigate the controllability of electromagnetically induced transparency (EIT) and Fano resonances in hybrid optomechanical system which is composed of cigar-shaped Bose-Eins…
