Dyadic Green Function Approach to Multichromophoric Forster Resonance Energy Transfer under Electromagnetic Fluctuations near Metallic Thin Films
Changhao Meng, Xin Chen, Zhenghua An
The near-field spectroscopic information is critically important to determine the Forster resonant energy transfer(FRET) rate and the distance dependence in the vicinity of metal s…
Non-Hermitian Linear Response Theory
Lei Pan, Xin Chen, Yu Chen +1
Linear response theory lies at the heart of quantum many-body physics because it builds up connections between the dynamical response to an external probe and correlation functions…
Linking invariant for the quench dynamics of a two-dimensional two-band Chern insulator
Xin Chen, Ce Wang, Jinlong Yu
We discuss the topological invariant in the (2+1)-dimensional quench dynamics of a two-dimensional two-band Chern insulator starting from a topological initial state (i.e., with a…
Competition between Chaotic and Non-Chaotic Phases in a Quadratically Coupled Sachdev-Ye-Kitaev Model
Xin Chen, Ruihua Fan, Yiming Chen +2
The Sachdev-Ye-Kitaev (SYK) model is a concrete solvable model to study non-Fermi liquid properties, holographic duality and maximally chaotic behavior. In this work, we consider a…
Measuring Topological Number of a Chern-Insulator from Quench Dynamics
Ce Wang, Pengfei Zhang, Xin Chen +2
In this letter we show how the topological number of a static Hamiltonian can be measured from a dynamical quench process. We focus on a two-band Chern insulator in two-dimension,…
The Rigorous Stochastic Matrix Multiplication Scheme for the Calculations of Reduced Equilibrium Density Matrices of Open Multilevel Quantum Systems
Xin Chen
Understanding the roles of the temporary and spatial structures of quantum functional noise in open multilevel quantum molecular systems attracts a lot of theoretical interests. I…
