QCD sum rule analysis of hidden strange tetraquark masses and radial excitations
Zhuo-Ran Huang, Wei Chen, Jason Ho +1
We revisit the light tetraquark states with quantum numbers using QCD sum rules, focusing on a complete set of derivative-free diquark-antidiquark interpolating cur…
Can wormholes and black holes be distinguished by magnification?
Ke Gao, Lei-Hua Liu
The magnification effect of wormholes and black holes has been extensively researched. It is crucial to provide a finite distance analysis to understand this magnification phenomen…
Microlensing and event rate of static spherically symmetric wormhole
Ke Gao, Lei-Hua Liu
The study focuses on the impact of microlensing in modern cosmology and introduces a new framework for the static spherically symmetrical wormhole in terms of the radial equation o…
Microlensing effects of wormholes associated to blackhole spacetimes
Ke Gao, Lei-Hua Liu, Mian Zhu
In this paper, we investigate the microlensing effects of wormholes associated to black hole spacetimes. Specifically, we work on three typical wormholes (WH): Schwarzschild WH, Ke…
Mimetic Curvaton
Xin-zhe Zhang, Lei-hua Liu, Taotao Qiu
In this paper, we investigate the primordial perturbations of inflation model induced from the multi-field mimetic gravity, where there are two field during inflation, and thus bot…
Microlensing effect of charged spherically symmetric wormhole
Lei-Hua Liu, Mian Zhu, Wentao Luo +2
We systematically investigate the microlensing effect of charged spherically symmetric wormhole, where the light source is remote from the throat. Remarkably, there will be at most…

Lei-Hua Liu
In light of our previous work \cite{Liu:2019xhn}, we investigate the possibility of the formation of a primordial black hole in the second inflationary process induced by the oscil…
Cosmological Complexity in K-essence
Ai-chen Li, Xin-Fei Li, Ding-fang Zeng +1
We calculate the cosmological complexity under the framework of scalar curvature perturbations for a K-essence model with constant potential. In particular, the squeezed quantum st…
Complexity of non-trivial sound speed in inflation
Lei-Hua Liu, Ai-Chen Li
In this paper, we study the impact of non-trivial sound on the evolution of cosmological complexity in inflationary period. The vacuum state of curvature perturbation could be trea…
Revised parameter in Curvaton Scenario
Lei-Hua Liu, Bin Liang, Ya-Chen Zhou +3
We revise the Non-Gaussianity of canonical curvaton scenario with a generalized formalism, in which it could handle the generic potentials. In various curvaton models, the ene…
Non-minimally coupled curvaton
Lei-Hua Liu, Tomislav Prokopec
We investigate two-field inflationary models in which scalar cosmological pertubations are generated via a spectator field nonminimally coupled to gravity, with the particular emph…
The running curvaton
Lei-Hua Liu, Wu-Long Xu
Inspired by \cite{Jiang:2018uce}, we propose a similar curvaton mechanism whose realization occurs in preheating process, in which the effective mass is running (its potential cons…
Analysis of inflationary model as
Lei-Hua Liu
We study the inflationary model of [Muller:1989rp] for using the result of Ref. [Motohashi:2014tra]. After reproducing the observable quantities: the power spectral ind…
Inflation in an effective gravitational model & asymptotic safety
Lei-Hua Liu, Tomislav Prokopec, Alexei A. Starobinsky
We consider an inflationary model motivated by quantum effects of gravitational and matter fields near the Planck scale. Our Lagrangian is a re-summed version of the effective Lagr…
Gravitational microlensing in Verlinde's emergent gravity
Lei-Hua Liu, Tomislav Prokopec
We propose gravitational microlensing as a way of testing the emergent gravity theory recently proposed by Eric Verlinde~\cite{Verlinde:2016toy}. We consider two limiting cases: th…
Emergent observable deSitter space from an Equation of Motion
Leihua Liu, Jiansen Zheng
We propose that de-Sitter space-time originates from Gaussian distribution in a quantum harmonic oscillator system. This equation associates with a massless Klein-Gordon equation.…

Charm-strange baryon strong decays in a chiral quark model
Lei-Hua Liu, Li-Ye Xiao, Xian-Hui Zhong
The strong decays of charm-strange baryons up to N=2 shell are studied in a chiral quark model. The theoretical predictions for the well determined charm-strange baryons, $Ξ_c^*(26…
