Boson Star Normal Modes
James Hung-Hsu Chan, Sergey Sibiryakov, Wei Xue
Boson stars are gravitationally bound objects that arise in ultralight dark matter models and form in the centers of galactic halos or axion miniclusters. We systematically study t…
Parity-Odd and Even Trispectrum from Axion Inflation
Xuce Niu, Moinul Hossain Rahat, Karthik Srinivasan +1
The four-point correlation function of primordial scalar perturbations has parity-even and parity-odd contributions and the parity-odd signal in cosmological observations is openin…
Gravitational Wave Probes of Massive Gauge Bosons at the Cosmological Collider
Xuce Niu, Moinul Hossain Rahat, Karthik Srinivasan +1
We extend the reach of the ``cosmological collider'' for massive gauge boson production during inflation from the CMB scales to the interferometer scales. Considering a Chern-Simon…
Signatures and Detection Prospects for sub-GeV Dark Matter with Superfluid Helium
Yining You, Jordan Smolinsky, Wei Xue +4
We explore the possibility of using superfluid helium for direct detection of sub-GeV dark matter (DM). We discuss the relevant phenomenology resulting from the scattering of an in…
Condensation and Evaporation of Boson Stars
James Hung-Hsu Chan, Sergey Sibiryakov, Wei Xue
Axion-like particles, including the QCD axion, are well-motivated dark matter candidates. Numerical simulations have revealed coherent soliton configurations, also known as boson s…
3+1 Dimension Schwinger Pair Production with Quantum Computers
Bin Xu, Wei Xue
Real-time quantum simulation of quantum field theory in (3+1)D requires large quantum computing resources. With a few-qubit quantum computer, we develop a novel algorithm and exper…
