Neutron stars and Pulsar timing arrays as Axion giant gyroscopes
Yiming Liu, Jinneng Luo, Sichun Sun
We consider the three-dimensional rotating motions of neutron stars blown by the "axion wind". Neutron star precession and spin can change from the magnetic moment coupling to the…
Implications of Pulsar Timing Array Results for High Frequency Gravitational Waves
Junsong Cang, Yu Gao, Yiming Liu +1
Several pulsar timing array (PTA) experiments such as NANOGrav and PPTA recently reported evidence of a gravitational wave (GW) background at nano-Hz frequency band. This signal ca…
Novel high-frequency gravitational waves detection with split cavity
Chu-Tian Gao, Yu Gao, Yiming Liu +1
Gravitational waves can generate electromagnetic effects inside a strong electric or magnetic field within the Standard Model and general relativity. Here we propose using a quarte…

Sichun Sun, Qi-Shu Yan, Xiaoran Zhao +1
Motivated by the recent rare B decays measurements, we study the matching procedure of operators in the low energy effective Hamiltonian and operators in the Standard…

Junxi Duan, Yu Gao, Chang-Yin Ji +3
The oscillating light axion field is known as wave dark matter. We propose an LC-resonance enhanced detection of the narrow band electric signals induced by the axion dark matter u…

Sichun Sun, Xing-Yu Yang, Yun-Long Zhang
The coherent oscillation of ultralight dark matter in the mass regime around eV induces changes in gravitational potential with the frequency in the nanohertz range. Thi…

Wolfgang Kilian, Sichun Sun, Qi-Shu Yan +2
We study the observability of new interactions which modify Higgs-pair production via vector-boson fusion processes at the LHC and at future proton-proton colliders. In an effectiv…
Challenges and Opportunities of Gravitational Wave Searches at MHz to GHz Frequencies

The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
Dark Fluxes from Accreting Black Holes and Direct Detections
Rong-Gen Cai, Sichun Sun, Bing Zhang +1
We discuss the possibility that accreting black hole systems can be sources for dark matter flux through several different mechanisms. We firstly discuss two types of systems: coro…
Gravitational Waves and Possible Fast Radio Bursts from Axion Clumps
Sichun Sun, Yun-Long Zhang
The axion objects such as axion mini-clusters and axion clouds around spinning black holes induce parametric resonances of electromagnetic waves through the axion-photon interactio…

Sichun Sun, Yun-Long Zhang
We discuss the de Sitter swampland and trans-Planckian censorship conjectures (TCC) from the entropy bound with quantum corrections, namely quantum version of Bousso bound and ener…
Dark Matter, Dark Photon and Superfluid He-4 from Effective Field Theory
A. Caputo, A. Esposito, E. Geoffray +2
We consider a model of sub-GeV dark matter whose interaction with the Standard Model is mediated by a new vector boson (the dark photon) which couples kinetically to the photon. We…

Rong-Gen Cai, Sunly Khimphun, Bum-Hoon Lee +3
We study a model of the emergent dark universe, which lives on the time-like hypersurface in a five-dimensional bulk spacetime. The holographic fluid on the hypersurface is assumed…
