Inverse-k Primordial Oscillations from a Symbolic Regression Search
Ze-Yu Peng, Qing-Yu Lan, Yun-Song Piao
Oscillatory features in the primordial power spectrum, potential signatures of new physics in the early universe, are usually searched for using fixed templates. In this work, we p…
Search for primordial black holes from gravitational wave populations using deep learning
Hai-Long Huang, Zhan-He Wang, Qing-Yu Lan +5
Gravitational waves (GWs) signals detected by the LIGO/Virgo/KAGRA collaboration might be sourced (partly) by the merges of primordial black holes (PBHs). The conventional hierarch…
Testing the wormhole echo hypothesis for GW231123
Qi Lai, Qing-Yu Lan, Zhan-He Wang +1
The short-duration gravitational-wave (GW) event GW231123 has inferred component masses in the pair-instability mass gap and exhibits a burst-like morphology with no clearly inspir…
Is GW190521 a gravitational wave echo of wormhole remnant from another universe?
Qi Lai, Qing-Yu Lan, Hao-Yang Liu +2
A particularly compelling aspect of the GW190521 event detected by the LIGO--Virgo--KAGRA (LVK) collaboration is that it has an extremely short duration, and lacks a clearly identi…
News-Aware Direct Reinforcement Trading for Financial Markets
Qing-Yu Lan, Zhan-He Wang, Jun-Qian Jiang +2
The financial market is known to be highly sensitive to news. Therefore, effectively incorporating news data into quantitative trading remains an important challenge. Existing appr…
Prepare inflationary universe via the Euclidean charged wormhole
Qing-Yu Lan, Yun-Song Piao
In this paper, we present a wavefunction of the universe, which correspond to an Euclidean charged wineglass (half)-wormholes semiclassically, as a possible creation for our inflat…
