Geometric-phase control of Krylov complexity in adiabatic dynamics
Han-Qi Zheng, Peng-Zhang He, Lei-Hua Liu +1
We show that geometric phases accumulated during adiabatic evolution can be converted into observable interference in Krylov space, leading to a geometric-phase-dependent Krylov os…
Quantum-information diagnostics of cosmological perturbations with nontrivial sound speed in inflation
Shi-Cheng Liu, Lei-Hua Liu, Bichu Li +2
In this work, we systematically investigate the quantum-information diagnostics of cosmological perturbations with a nontrivial sound speed, utilizing a normalized open two-mode sq…
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…
Revisit the relationship between spread complexity rate and radial momentum
Peng-Zhang He
This article discusses the relationship between the boundary spread complexity rate and the radial momentum in the bulk within the framework of AdS/CFT. We demonstrate that the rad…
Krylov Complexity in the Schrödinger Field Theory
Peng-Zhang He, Hai-Qing Zhang
We investigate the Krylov complexity of Schrödinger field theories, focusing on both bosonic and fermionic systems within the grand canonical ensemble that includes a chemical pote…
Probing Krylov Complexity in Scalar Field Theory with General Temperatures
Peng-Zhang He, Hai-Qing Zhang
Krylov complexity characterizes the operator growth in the quantum many-body systems or quantum field theories. The existing literatures have studied the Krylov complexity in the l…
