Gravitational Wave Diffractive Images Reveal the Structure of Astrophysical Objects
Han Gil Choi, Sunghoon Jung, Volodymyr Takhistov
Scattering patterns encode the structure of extended objects, as demonstrated by charged particle scattering on atomic nuclei. Gravitational wave (GW) diffraction offers an analogo…
Transient PULSE: Code for the Transient Propagation of UltraLight (pseudo)Scalars to Earth
Jason Arakawa, Charles Cheung, Muhammad Hani Zaheer +2
We present Transient PULSE, a software package that numerically implements a previously developed source-to-detector framework for transient ultralight bosonic signals from astroph…
Moving a Detector to Probe New Neutrino Interactions: IWCD at Hyper-Kamiokande
Thomas Schwemberger, Volodymyr Takhistov
Moving a detector through a beam with a spatially varying energy spectrum exposes the same target and apparatus to distinct incident spectra, enabling interaction spectroscopy. Whi…
Halo-Independent Quantum Sensor Probes of Low-Velocity Dark Matter
Muping Chen, Graciela B. Gelmini, Volodymyr Takhistov +1
We present a halo-independent framework for sub-GeV dark matter (DM) direct detection using quantum sensors with sub-eV energy thresholds. Such detectors enable access to low DM ve…
Universal Suppression of Gravitational Waves from Black Hole Evaporation Dynamics
Xin-Chen He, Xiao-Han Ma, Misao Sasaki +1
Evaporating black holes can leave distinct imprints on gravitational wave (GW) backgrounds. We show that black hole populations with finite width mass distributions exhibit a unive…
Echoes of Nucleon Decay from Long-Lived Particles
Patrick Adolf, Chandan Hati, Martin Hirsch +1
Nucleon decay searches provide uniquely sensitive probes of baryon number violation and physics beyond the Standard Model. We propose a new class of nucleon decay observables invol…
Casimir Geometry as a Probe of Short Range Forces
Xiaolin Ma, Volodymyr Takhistov, Hideo Iizuka
Casimir force searches provide among the most sensitive laboratory probes of new short range interactions. Existing constraints rely almost exclusively on a single geometry. We sho…
Experimental Tests of Baryon and Lepton Number Conservation
Volodymyr Takhistov
Baryon number () conservation underlies the apparent stability of ordinary matter by forbidding the decay of nucleons, while lepton number () conservation plays a central rol…
Multiple Axions in Laboratory Experiments
Arturo de Giorgi, Joerg Jaeckel, Sebastian Monath +1
Axions and axion-like particles generically appear in extensions of the Standard Model. While many searches assume only a single axion species, there may exist a whole spectrum of…
Multimessenger Constraints on Supermassive Dark Stars and Their Black Hole Remnants
Marco Manno, Thomas Schwemberger, Volodymyr Takhistov
Dark matter (DM) annihilation can power the first generation of stars as long lived dark stars (DSs) that grow to supermassive scales and event…
Beyond Qubits: Multilevel Quantum Sensing for Dark Matter
Xiaolin Ma, Volodymyr Takhistov, Norikazu Mizuochi +1
Quantum sensing with qubits has advanced fundamental physics searches, but higher dimensional systems offer untapped potential. We present a universal qutrit framework that yields…
Probing Dark Matter Interactions with Stellar Motion near Sagittarius A*
R. Andrew Gustafson, Ian M. Shoemaker, Volodymyr Takhistov
Stars orbiting Sgr A* at the Milky Way's center provide a unique laboratory to test gravity and dark matter (DM). We demonstrate that DM interactions in stellar interiors induce a…
