Thermocapillary stabilization of Liquid Space Telescopes
Ryan Engle, Valeri Frumkin
We investigate how spatially uniform, time-modulated heating can be used to stabilize a thin liquid mirror in microgravity. Periodic heating generates oscillatory thermocapillary f…
Modeling the Thermal Behavior of Photopolymers for In-Space Fabrication
Jonathan Ericson, Daniel Widerker, Eytan Stibbe +15
Future long-duration space missions will require in-situ, on-demand manufacturing of tools and components. Photopolymer-based processes are attractive for this purpose due to their…
Observation of the Aharonov-Bohm Effect in Pilot-Wave Hydrodynamics
Georgi Gary Rozenman, Kyle I. McKee, Arnaud Lazarus +2
We report the results of an experimental study of an analog of the Aharonov-Bohm (AB) effect achieved with the hydrodynamic pilot-wave system. A walking droplet is confined to an a…
LiquiFab -- Building with liquids in weightlessness
Erez Hochman, Aaron Sprecher, Kateryna Suzina +4
Existing digital manufacturing methods can be broadly divided into subtractive approaches, where material is removed from a bulk to reveal the desired form, and additive methods, i…
Topological guidance of a self-propelled particle
Ethan Andersson, Valeri Frumkin
Topological phenomena typically govern the behavior of delocalized waves, giving rise to robust transport in electronic, photonic, and mechanical systems. Whether similar principle…
In-space manufacturing of optical lenses: Fluidic Shaping aboard the International Space Station
Omer Luria, Mor Elgarisi, Eytan Stibbe +12
In-space manufacturing technologies are vital for enabling advanced space missions and addressing logistical limitations of space exploration. While additive manufacturing has prog…
Optical Design Pathways to Fluidic Space-Assembled Reflectors & Dual-Configuration Spectrographs for Characterizing Exo-Earths
Enrico Biancalani, Edward Balaban, Ruslan Belikov +14
| We present a conceptual framework for optically designing space-assembled telescopes whose primary mirror is formed via the enabl…
Diffraction of walking drops by a standing Faraday wave
Bauyrzhan K. Primkulov, Davis J. Evans, Valeri Frumkin +2
The Kapitza-Dirac effect is the diffraction of quantum particles by a standing wave of light. We here report an analogous phenomenon in pilot-wave hydrodynamics, wherein droplets w…
Superradiant droplet emission from a single hydrodynamic cavity near a reflective boundary
Konstantinos Papatryfonos, Jemma W. Schroder, Valeri Frumkin
Recent advances in manipulating droplet emissions from a thin vibrating fluid using submerged cavities, have introduced an innovative platform for generating hydrodynamic analogs o…
Fluidic Approach to Corrective Eyewear Manufacturing in Low-Resource Settings
Mor Elgarisi, Omer Luria, Yotam Katzman +3
Limited access to corrective eyewear remains a significant medical, societal, and economic challenge, even in the 21st century. More than 1 billion people suffer from uncorrected v…
Misinference of interaction-free measurement from a classical system
Valeri Frumkin, John W. M. Bush
Interaction-free measurement is thought to allow for quantum particles to detect objects along paths they never traveled. As such, it represents one of the most beguiling of quantu…
Fluidic Shaping and in-situ Measurement of Liquid Lenses in Microgravity
Omer Luria, Mor Elgarisi, Valeri Frumkin +9
In the absence of gravity, surface tension dominates over the behavior of liquids. While this often poses a challenge in adapting Earth-based technologies to space, it can also pro…
Coupled instabilities drive quasiperiodic order-disorder transitions in Faraday waves
Valeri Frumkin, Shreyas Gokhale
We present an experimental study of quasiperiodic transitions between a highly ordered square-lattice pattern and a disordered, defect-riddled state, in a circular Faraday system.…
Real surreal trajectories in pilot-wave hydrodynamics
Valeri Frumkin, David Darrow, Ward Struyve +1
In certain instances, the particle paths predicted by Bohmian mechanics are thought to be at odds with classical intuition. A striking illustration arises in the interference exper…
Superradiant droplet emission from parametrically excited cavities
Valeri Frumkin, Konstantinos Papatryfonos, John W. M. Bush
Superradiance occurs when a collection of atoms exhibits cooperative, spontaneous emission of photons at a rate that exceeds that of its component parts. Here, we reveal a similar…
Programmable thermocapillary shaping of thin liquid films
Ran Eshel, Valeri Frumkin, Matan Nice +7
We present a method that leverages projected light patterns as a mechanism for freeform deformations of a thin liquid film via the thermocapillary effect. We developed a closed-for…
Fluidic Shaping of Freeform Optical Components
Mor Elgarisi, Valeri Frumkin, Omer Luria +1
Freeform optical components offer significant compactization of multi-lens systems, as well as advanced manipulation of light that is not possible with traditional systems. However…
Fluidic Shaping of Optical Components
Valeri Frumkin, Moran Bercovici
Current methods for fabricating lenses rely on mechanical processing of the lens or mold, such as grinding, machining, and polishing. The complexity of these fabrication processes…
Dipolar thermocapillary motor and swimmer
Valeri Frumkin, Moran Bercovici
We present a theoretical description and an experimental realization of a thermocapillary dipole induced in a Hele-Shaw cell under a steady temperature gradient. We demonstrate exp…
