Geometric Amplification via Non-Hermitian Berry Phase
J. R. Lane, C. Guria, J. Höller +3
Despite their apparent simplicity, coupled oscillators exhibit surprisingly complex phenomena. Two notable examples are Berry phase (a geometric or topological aspect of the oscill…
Resolving the topology of encircling multiple exceptional points
Chitres Guria, Qi Zhong, Sahin K. Ozdemir +3
Non-Hermiticity has emerged as a new paradigm for controlling coupled-mode systems in ways that cannot be achieved with conventional techniques. One aspect of this control that has…
Measuring the knot of non-Hermitian degeneracies and non-commuting braids
Yogesh S. S. Patil, Judith Höller, Parker A. Henry +6
Any system of coupled oscillators may be characterized by its spectrum of resonance frequencies (or eigenfrequencies), which can be tuned by varying the system's parameters. The re…
Giant Tunable Mechanical Nonlinearity in Graphene-Silicon Nitride Hybrid Resonator
Rajan Singh, Arnab Sarkar, Chitres Guria +4
High quality factor mechanical resonators have shown great promise in developing classical or quantum technologies. Simultaneously, progress has been made in developing controlled…
