Hybrid-spin decoupling for noise-resilient DC quantum sensing
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +3
The excellent sensitivities of quantum sensors are a double-edged sword: minuscule quantities can be observed, but any undesired signal acts as noise. This is challenging when dete…
Detecting dark matter using optically trapped Rydberg atom tweezer arrays
So Chigusa, Taiyo Kasamaki, Toshi Kusano +6
A new scheme for detecting wave-like dark matter (DM) using Rydberg atoms is proposed. Recent advances in trapping and manipulating Rydberg atoms make it possible to use Rydberg at…
Light Dark Matter Detection with Sub-eV Transition-Edge Sensors
Muping Chen, Volodymyr Takhistov, Kazunori Nakayama +1
We present a comprehensive analysis of high-resolution transition-edge sensors (TESs) as a quantum sensing platform for detecting dark matter (DM). Operating near the thermodynamic…
Entanglement-enhanced AC magnetometry in the presence of Markovian noises
Thanaporn Sichanugrist, Hajime Fukuda, Takeo Moroi +5
Entanglement is a resource to improve the sensitivity of quantum sensors. In an ideal case, using an entangled state as a probe to detect target fields, we can beat the standard qu…
Dual Gravitational Wave Signatures of Instant Preheating
Wei-Yu Hu, Kazunori Nakayama, Volodymyr Takhistov +1
In the instant preheating scenario efficient particle production occurs immediately following the period of inflationary expansion in the early Universe. We demonstrate that instan…
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…
Gravitational Wave Probe of Planck-scale Physics After Inflation
Weiyu Hu, Kazunori Nakayama, Volodymyr Takhistov +1
Particle decays are always accompanied by the emission of graviton quanta of gravity through bremsstrahlung processes. However, the corresponding branching ratio is suppressed by t…
Effects of gravitational particle production on Higgs portal dark matter
Soichiro Izumine, Kazunori Nakayama
The gravitational interaction is ubiquitous and the effect of gravitational particle production necessarily contributes to the dark matter abundance. A simple candidate of dark mat…
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…
