Numerical simulations of primordial black hole formation via delayed first-order phase transitions
Zhuan Ning, Xiang-Xi Zeng, Rong-Gen Cai +1
We perform fully nonlinear, spherically symmetric numerical simulations of superhorizon false-vacuum-domain (FVD) collapse in a coupled gravity-scalar-fluid system to study primord…
A Scalable Benchmark Test Suite for Dynamic Multi-Objective Optimization with a Changing Number of Objectives
Ke Shang, Zhiyun Xiao, Yuxuan Liu +3
Dynamic multi-objective optimization with a changing number of objectives has recently attracted increasing attention due to its relevance to real-world problems whose evaluation c…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
Resolving the Planck-DESI tension by nonminimally coupled quintessence
Jia-Qi Wang, Rong-Gen Cai, Zong-Kuan Guo +1
The Planck measurement of the cosmic microwave background (CMB) has established the -cold-dark-matter (CDM) model as the concordant model along with other observations. How…
Constraining interacting dark energy models with black hole superradiance
Zhen-Hong Lyu, Rong-Gen Cai, Shao-Jiang Wang +1
The recent preference for a dynamical dark energy (DE) from the Dark Energy Spectroscopic Instrument seems to call for interactions between DE and dark matter (DM), either from dir…
Scalar-induced gravitational waves with non-Gaussianity up to all orders
Xiang-Xi Zeng, Zhuan Ning, Rong-Gen Cai +1
Scalar-induced gravitational waves (SIGWs) are ubiquitous in many early-Universe processes accompanied by non-Gaussianity; while Gaussian perturbation can generate significant SIGW…
