Exceptional points (EPs), at which two or more eigenvalues and eigenstates of a resonant
system coalesce, are associated with non-Hermitian Hamiltonians with gain and/or loss …

Optical sensors, crucial in diverse fields like gravitational wave detection, biomedical
imaging, and structural health monitoring, rely on optical phase to convey valuable …

Continuum Landau modes—predicted recently in a non-Hermitian Dirac Hamiltonian under
a uniform magnetic field—are continuous bound states with no counterparts in Hermitian …

We show that an oscillator array prefers to operate at an exceptional point of degeneracy
(EPD) occurring in a waveguide periodically loaded with discrete nonlinear gain and …

Bifurcation of exceptional points (EPs), particularly higher-order EPs, can offer applications
in metrology by amplifying sensitivity, but this method suffers from a tradeoff between …

Exceptional points (EPs) are degeneracies of two or more natural modes of open systems,
which lead to unusual wave phenomena. Despite the robustness against imperfections of …

We develop a Coherent Perfect Absorption (CPA) protocol for cases where scale invariance
is violated due to the presence of nonlinear mechanisms. We demonstrate, using a …

Exceptional points (EPs) are degeneracies at which two or more eigenvalues and
eigenstates of a non-Hermtian system coalesce. Dynamically encircling EPs leads to chiral …

This thesis focuses on two interdependent research thrusts:(i) investigating the fundamental
structure-property-function relationship in hierarchically architected vertically aligned carbon …

An inductor–capacitor (LC) passive wireless sensor is essential to physical, chemical, and
biological sensing for scenarios where physical access is difficult. For emerging applications …
