Experimental observation of PT symmetry breaking near divergent exceptional points
M. Sakhdari, M. Hajizadegan, Q. Zhong +3
Standard exceptional points (EPs) are non-Hermitian degeneracies that occur in open systems. At an EP, the Taylor series expansion becomes singular and fails to converge -- a featu…
Generalized Parity-Time Symmetry Condition for Enhanced Sensor Telemetry
Pai-Yen Chen, Maryam Sakhdari, Mehdi Hajizadegan +4
Wireless sensors based on micro-machined tunable resonators are important in a variety of applications, ranging from medical diagnosis to industrial and environmental monitoring.Th…
Giant Photoresponsivity of Mid-Infrared Hyperbolic Metamaterials in the Quantum Regime
Pai-Yen Chen, Mehdi Hajizadegan, Maryam Sakhdari +1
We explore broadband, wide-angle mid-infrared rectification based on nanopatterned hyperbolic metamaterials (HMM), composed of two dissimilar metals separated by a sub-nanometer tu…
