Coherent control of an optical tweezer phonon laser
Kai Zhang, Kewen Xiao, Danika Luntz-Martin +4
The creation and manipulation of coherence continues to capture the attention of scientists and engineers. The optical laser is a canonical example of a system that, in principle,…
All-dielectric hybrid VIS-NIR dual-function metasurface

Experimental realization of supergrowing fields
Sethuraj K. R., Tathagata Karmakar, S. A. Wadood +2
Supergrowth refers to the local amplitude growth rate of a signal being faster than its fastest Fourier mode. In contrast, superoscillation pertains to the variation of the phase.…
Supergrowth and sub-wavelength object imaging
Tathagata Karmakar, Abhishek Chakraborty, A. Nick Vamivakas +1
We further develop the concept of supergrowth [Jordan, Quantum Stud.: Math. Found. , 285-292 (2020)], a phenomenon complementary to superoscillation, defined as the loc…
Super-phenomena in arbitrary quantum observables
Andrew N. Jordan, Yakir Aharonov, Daniele C. Struppa +6
Superoscillations occur when a globally band-limited function locally oscillates faster than its highest Fourier coefficient. We generalize this effect to arbitrary quantum mechani…
Excited-state spin-resonance spectroscopy of V defect centers in hexagonal boron nitride
Nikhil Mathur, Arunabh Mukherjee, Xingyu Gao +5
The recently discovered spin-active boron vacancy (V) defect center in hexagonal boron nitride (hBN) has high contrast optically-detected magnetic resonance (ODMR) at…
Coherence effects on estimating general sub-Rayleigh object distribution moments

Analyses based on quantum metrology have shown that the ability to localize the positions of two incoherent point sources can be significantly enhanced through the use of mode sort…
Confocal super-resolution microscopy based on a spatial mode sorter
Katherine K. M. Bearne, Yiyu Zhou, Boris Braverman +6
Spatial resolution is one of the most important specifications of an imaging system. Recent results in quantum parameter estimation theory reveal that an arbitrarily small distance…
The Structure and Dispersion of Exciton-Trion-Polaritons in Two-Dimensional Materials: Experiments and Theory
Okan Koksal, Minwoo Jung, Christina Manolatou +3
The nature of trions and their interaction with light has remained a puzzle. The composition and dispersion of polaritons involving trions provide insights into this puzzle. Trions…
Injection locking of a levitated optomechanical oscillator for precision force sensing
Siamak Dadras, Robert M. Pettit, Danika R. Luntz-Martin +3
We report on the injection locking of an optically levitated nanomechanical oscillator (a silica nanosphere) to resonant intensity modulations of an external optical signal. We exp…
Exciton-Trion-Polaritons in Two-Dimensional Materials
