A quantum information method for early universe with non-trivial sound speed

Shi-Cheng Liu, Lei-Hua Liu, Bichu Li +2

Many quantum gravitational frameworks, such as DBI inflation, k-essence, and effective field theories obtained by integrating out heavy modes, can lead to a non-trivial sound speed…

Cosmological complexity of the modified dispersion relation

Tao Li, Lei-Hua Liu

Complexity will be more and more essential in high-energy physics. It is naturally extended into the very early universe. Considering the universe as a quantum chaotic system, the…

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…

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…

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…
