Electron-positron pair production in spatially inhomogeneous electric fields with quadratically symmetric chirp
Le Le Chen, Xiao-Ting Xu, Rong-An-Tang +3
Electron-positron pair production from vacuum in spatially inhomogeneous electric fields with quadratically symmetric chirp is studied within the real-time Dirac-Heisenberg-Wigner…

Spatial covariance of KPZ from flat initial profile
Le Chen, Juan J. Jiménez
We study the fixed-time spatial covariance of the KPZ equation with flat initial profile. Using Malliavin calculus and a Clark-Ocone representation, we show that as ,…

A class of d-dimensional directed polymers in a Gaussian environment
Le Chen, Cheng Ouyang, Samy Tindel +1
We introduce and analyze a broad class of continuous directed polymers in driven by Gaussian environments that are white in time and spatially correlated, under Dala…
