Unified Gas Heating Constraints on Extended Dark Matter Compact Objects
TaeHun Kim, Philip Lu, Volodymyr Takhistov
We present the first unified constraints on a broad class of extended dark matter compact objects (EDCOs) from interstellar gas heating. These include axion stars, Q-balls, axion m…
Multimessenger Astronomy Beyond the Standard Model: New Window from Quantum Sensors
Jason Arakawa, Muhammad H. Zaheer, Volodymyr Takhistov +3
Ultralight bosonic (ULB) fields with mass ~eV often arise in theories beyond the Standard Model (SM). If such fields exist, violent astrophysical events that result in e…
Nuclear Spin Metrology with Nitrogen Vacancy Center in Diamond for Axion Dark Matter Detection
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +3
We present a method to directly detect the axion dark matter using nitrogen vacancy centers in diamonds. In particular, we use metrology leveraging the nuclear spin of nitrogen to…
Energy-dependent Boosted Dark Matter from Diffuse Supernova Neutrino Background
Anirban Das, Tim Herbermann, Manibrata Sen +1
Diffuse neutrinos from past supernovae in the Universe present us with a unique opportunity to test dark matter (DM) interactions. These neutrinos can scatter and boost the DM part…
Misalignment production of vector boson dark matter from axion-SU(2) inflation
Tomohiro Fujita, Kai Murai, Kazunori Nakayama +1
We present a new mechanism to generate a coherently oscillating dark vector field from axion-SU(2) gauge field dynamics during inflation. The SU(2) gauge field acquires a nonzero b…
Quantum entanglement of ions for light dark matter detection
Asuka Ito, Ryuichiro Kitano, Wakutaka Nakano +1
A detection scheme is explored for light dark matter, such as axion dark matter or dark photon dark matter, using a Paul ion trap system. We first demonstrate that a qubit, constru…
Effects of Finite Material Size On Axion-magnon Conversion
So Chigusa, Asuka Ito, Kazunori Nakayama +1
Magnetic materials are particularly favorable targets for detecting axions interacting with electrons because the collective excitation of electron spins, the magnon, can be excite…
Hunting Nonstandard Neutrino Interactions and Leptoquarks in Dark Matter Experiments
Thomas Schwemberger, Volodymyr Takhistov, Tien-Tien Yu
Next generation direct dark matter (DM) detection experiments will have unprecedented capabilities to explore coherent neutrino-nucleus scattering (CENS) complementary to dedica…
Dark matter detection using nuclear magnetization in magnet with hyperfine interaction
So Chigusa, Takeo Moroi, Kazunori Nakayama +1
We consider the possibility to detect cosmic light dark matter (DM), i.e., axions and dark photons, of mass eV and eV, by magnetic excitation in a mag…
Chiral anomaly in a (1+1)-dimensional Floquet system under high-frequency electric fields
Kenji Fukushima, Yoshimasa Hidaka, Takuya Shimazaki +1
We investigate the chiral anomaly in a Floquet system under a time-periodic electric field in (1+1) dimensions. Using the van~Vleck high-frequency expansion, we analytically calcul…
Viable Vector Coherent Oscillation Dark Matter
Naoya Kitajima, Kazunori Nakayama
We construct a viable model of the vector coherent oscillation dark matter. The vector boson is coupled to the inflaton through the kinetic function so that the effective Hubble ma…
Zero Casimir Force in Axion Electrodynamics and the Search for a New Force
Yohei Ema, Masashi Hazumi, Hideo Iizuka +2
We point out that there is a stable configuration of metal plates where the Casimir force is vanishing in axion electrodynamics. We consider a concrete setup involving Weyl semimet…
Halo-Independent Dark Matter Electron Scattering Analysis with In-Medium Effects
Muping Chen, Graciela B. Gelmini, Volodymyr Takhistov
Dark matter (DM)-electron scattering is a prime target of a number of direct DM detection experiments and constitutes a promising avenue for exploring interactions of DM in the sub…
Instability of the Electroweak Vacuum in Starobinsky Inflation
Qiang Li, Takeo Moroi, Kazunori Nakayama +1
We study the stability of the electroweak vacuum during and after the Starobinsky inflation, assuming the existence of the non-minimal Higgs coupling to the Ricci scalar. In the St…
Anisotropic cosmic optical background bound for decaying dark matter in light of the LORRI anomaly
Kazunori Nakayama, Wen Yin
Recently anomalous flux in the cosmic optical background (COB) has been reported by the New Horizon observations. The COB flux is , at the LO…
Scalar field couplings to quadratic curvature and decay into gravitons
Yohei Ema, Kyohei Mukaida, Kazunori Nakayama
Any field, even if it lives in a completely hidden sector, interacts with the visible sector at least via the gravitational interaction. In this paper, we show that a scalar field…
Cosmological Dependence of Sterile Neutrino Dark Matter With Self-Interacting Neutrinos
Carlos Chichiri, Graciela B. Gelmini, Philip Lu +1
Unexplored interactions of neutrinos could be the key to understanding the nature of the dark matter (DM). In particular, active neutrinos with new self-interactions can produce ke…
