Emergence and Ordering of Polygonal Breathers in Polariton Condensates
Samuel N. Alperin, Natalia G. Berloff
We show that the simultaneous driving of a polariton condensate with both nonresonant and n^th order resonant pump frequencies allows for a generic mechanism of breather formation;…
Multiply Charged Vortex States of Polariton Condensates
Samuel N. Alperin, Natalia G. Berloff
The existence of quantized vortices is a key feature of Bose-Einstein condensates. In equilibrium condensates only quantum vortices of unit topological charge are stable, due to th…
Formation and Dynamics of Quantum Hydrodynamical Breathing Ring Solitons
Samuel N. Alperin, Natalia G. Berloff
We show that exciton-polariton condensates may exhibit a new fundamental, self-localized nonlinear excitation not seen in other quantum hydrodynamical systems, which takes the form…
Quantum Turbulent Structure in Light
Samuel N. Alperin, Abigail L. Grotelueschen, Mark E. Siemens
The infinite superpositions of random plane waves are known to be threaded with vortex line singularities which form complicated tangles and obey strict topological rules. We obser…
Efficient Modal Decomposition of Vortex Beams via Holographically Reconstructed Phase
Jasmine M. Knudsen, Samuel N. Alperin, Andrew A. Voitiv +3
We use phase-shifting digital holography to measure the amplitude and phase of twisted light. In our experiment, a spatial light modulator generates the studied vortex beams in add…
The Angular Momentum of Topologically Structured Darkness
Samuel N. Alperin, Mark E. Siemens
We theoretically analyze and experimentally measure the extrinsic angular momentum contribution of topologically structured darkness found within fractional vortex beams, and show…
