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…
Krylov complexity and Wightman power spectrum with positive chemical potential in Schrödinger field theory
Peng-Zhang He, Lei-Hua Liu, Hai-Qing Zhang +1
We study Krylov complexity in Schrödinger field theory in the grand canonical ensemble with chemical potential , with an emphasis on the qualitatively new features that arise fo…
Microlensing of dark matter models in the Milky Way
Bichu Li, Chan-Yu Tang, Zhuo-Ran Huang +1
We investigate constraints on the abundance of primordial black holes (PBHs) as dark matter (DM) candidates using five years of microlensing data from the OGLE survey. While the ma…
Inflationary power spectrum from the Lanczos algorithm
Ke-Hong Zhai, Lei-Hua Liu, Hai-Qing Zhang
The generalized Lanczos algorithm can provide a universal method for constructing the wave function under the group structure of Hamiltonian. Based on this fact, we obtain an open…
