Neural Controlled Directional Frame Generation for Sprite Animation
Kenneth Alonso, Gustavo Patow
Sprite-based animation remains prevalent in video game development, but production workflows require capabilities beyond traditional in-betweening. While existing neural interpolat…
Trapping of nanofabricated SiO high-aspect-ratio discs in an optical lattice
Shelby Klomp, Shafaq Gulzar Elahi, Scott Grudichak +13
We describe the nanofabrication and loading of lithographically patterned, high aspect ratio m diameter silicon dioxide discs with thickness of nm into an optical sta…
Mathematical framework for simulation of non-perturbative cavity optomechanics with plate-like dielectrics
Andrew Laeuger, Nancy Aggarwal
Cavity optomechanical models typically treat a sensor either as a perturbative polarizable object in a pre-existing optical field, or solve the field at a fixed equilibrium and lin…
Nonperturbative optomechanics with thin, weakly reflective intracavity dielectrics
Andrew Laeuger, Nancy Aggarwal
Levitated dielectric sensors are often treated as perturbative probes of a pre-existing optical field. We show that this picture fails for a novel sensor geometry: a dielectric pla…
Fiber-based scanning levitated nanoparticle force sensor near a metalized membrane
Andrew M. Dana, Samuel J. Borden, Nia Burrell +10
We describe a fiber-based dual-beam trap for dielectric nanospheres with the ability to transfer the trapped particles into a retro-reflective standing-wave trap within micron-rang…
On Stochastic Memory Backgrounds In LISA
James Buda, Andrew Laeuger, Yanbei Chen
Gravitational-wave (GW) memory is a permanent change in spacetime geometry induced by a burst of gravitational waves. It is theoretically interesting for its connection to asymptot…
From driven oscillations to free ringdown: a particle plunging into Kerr
Colin Weller, Andrew Laeuger, Fulin Li +5
We show that a ringdown waveform can admit a constant-coefficient quasinormal-mode (QNM) representation while its individual QNM-pole contributions remain driven. To establish this…
Complex frequency evolution of direct waves from binary black hole mergers
Ling Sun, Sizheng Ma, Patrick P. Chen +3
While no signal originating at a black hole's event horizon can reach future null infinity, information about the horizon and its immediate vicinity can be encoded in asymptotic pr…
Chiral symmetry and black hole isospectrality
Colin Weller, Dongjun Li, Pratik Wagle +3
We prove that black-hole isospectrality between linearly independent solutions follows whenever radiative metric and matter perturbations are reconstructed from complex master vari…
Gravitational wave signal and noise response of an optically levitated sensor in a Fabry-Pérot cavity
Andrew Laeuger, Shafaq Gulzar Elahi, Shelby Klomp +8
Optically levitated sensors inside a Fabry-Pérot cavity have been proposed for high-frequency gravitational-wave (GW) detection, though their configuration for gravitational wave s…
No hair but plenty of feathers: are birds black holes?
Andrew Laeuger, Taylor Knapp
The imitative verb "chirp" is thought to originate from 16th-century Middle English. Meanwhile, this same word has been used to describe the gravitational waves (GWs) emitted from…
Prospects for High-Frequency Gravitational-Wave Detection with GEO600
Christopher M. Jungkind, Brian C. Seymour, Andrew Laeuger +1
Current ground-based interferometers are optimized for sensitivity from a few tens of Hz to about 1 kHz. While they are not currently utilized for GW detection, interferometric det…
The ringdown of a black hole surrounded by a thin shell of matter
Andrew Laeuger, Colin Weller, Dongjun Li +1
Recent studies have shown that far-field perturbations to the curvature potential of a black hole spacetime may destabilize its quasinormal mode (QNM) spectrum while only mildly af…
Simulating the Galactic population of axion clouds around stellar-origin black holes: Gravitational wave signals in the 10-100 kHz band
Jacob R. Sprague, Shane L. Larson, Zhiyuan Wang +6
Ultralight scalar fields can experience runaway `superradiant' amplification near spinning black holes, resulting in a macroscopic `axion cloud' which slowly dissipates via continu…
Measuring Supermassive Black Hole Properties via Gravitational Radiation from Eccentrically Orbiting Stellar Mass Black Hole Binaries
Andrew Laeuger, Brian Seymour, Yanbei Chen +1
There may exist stellar-mass binary black holes (BBH) which merge while orbiting nearby a supermassive black hole (SMBH). In such a triple system, the SMBH will modulate the gravit…
Optical trapping of high-aspect-ratio NaYF hexagonal prisms for kHz-MHz gravitational wave detectors
George Winstone, Zhiyuan Wang, Shelby Klomp +9
We present experimental results on optical trapping of Yb-doped NaYF sub-wavelength-thickness high-aspect-ratio hexagonal prisms with a micron-scale radius. The prisms are trap…
