Formation of holographic vortex in a rotating shell-shaped superfluid
Chang-Xu Yan, Hao-Ran Chang, Meng Gao +2
We investigate the holographic superfluid dynamics subjected to external rotation on a spherical geometry. Through a linear perturbation analysis, we identify several dynamically u…
Fermionic Love number of higher-dimensional Reissner-Nordström black holes
Xiankai Pang, Yu Tian, Hongbao Zhang +1
In this paper, we generalize our previous work on the fermionic tidal Love numbers (TLNs) to higher-dimensional Reissner-Nordström black holes. The massless Dirac equation is solv…
Internal structure of Hayward black holes
Caiying Shao, Jun-Qi Guo, Yu Tian +1
Regular black holes, free of central singularities, provide an ideal laboratory for probing the geometric structure of spacetime. The global structure of some regular black holes,…
Tidal Love numbers and the dynamical instability of AdS bubbles
Gerui Chen, Yu Tian, Hongbao Zhang
In this work, we study non-radial perturbations of AdS bubbles and their tidal Love numbers (TLNs). The odd- and even-parity TLNs are computed up to in the limit $k \to \inft…
Transition of vortex dipole dynamics in holographic superfluids
Yu-Kun Yan, Shanquan Lan, Yu Tian +1
Using holographic duality, we reveal a transition in vortex dipole dynamics below a critical dipole size in strongly interacting superfluids, characterized by a significant suppres…
Can Oscillatory and Persistent Nonlinearities Be Bridged in Black Hole Ringdown?
Jun-Xi Shi, Zhen-Tao He, Jiageng Jiao +4
Quadratic quasinormal modes (QQNMs) and Christodoulou memory effect are key nonlinear phenomena in gravitational wave physics. QQNMs characterize the near zone nonlinear response o…
