Vortex states and entanglement properties in multiphoton pair production
Hong-Hao Fan, Lie-Juan Li, Zhi-Hang Yao +3
We investigate the multiphoton pair production in circularly polarized field via two level model. There appears obvious discrete ring structures in the momentum distribution of the…
Spin effect in vacuum pair production under two-color rotating electric fields
Zhao-Yuan Chen, Orkash Amat, Jin-hui Bai +1
We investigated the spin effect on the vacuum pair production by Dirac-Heisenberg-Wigner (DHW) formalism under two-color counter-rotating electric fields. We primarily studied the…
Axial current as the origin of quantum intrinsic orbital angular momentum
Orkash Amat, Nurimangul Nurmamat, Yong-Feng Huang +9
We show that the axial current density is the physical origin (generator) of quantum intrinsic orbital angular momentum (IOAM). Without the axial current, the IOAM of particles van…
Spin resolved momentum spectra for vacuum pair production via a generalized two level model
Orkash Amat, Hong-Hao Fan, Suo Tang +2
We have formulated a generalized two level model for studying the pair production in multidimensional time-dependent electric fields. It can provide momentum spectra with fully spi…
Spin Effect induced Momentum Spiral and Asymmetry Degree in Pair Production
Li-Na Hu, Hong-Hao Fan, Orkash Amat +2
Spin effect on the pair production under circularly polarized fields are investigated. Significantly different from what momentum spirals caused by two counter-rotating fields with…
Asymmetric pulse effects on pair production in chirped electric fields
Neng-Zhi Chen, Orkash Amat, Li-Na Hu +2
We investigate the effects of the asymmetric pulse shapes on electron-positron pair production in three distinct fields: chirp-free, small frequency chirp, and large frequency chir…

Orkash Amat, Li-Na Hu, Mamat Ali Bake +2
Effect of spatially oscillating fields on the electron-positron pair production is studied numerically and analytically when the work done by the electric field over its spatial ex…
Momentum spirals in multiphoton pair production revisited
Li-Na Hu, Orkash Amat, Li Wang +3
Spirals in multiphoton pair production are revisited by two counter-rotating fields with time delay for different cycles in pulse. Novel findings include that for subcycle fields,…
Phase effect and symmetry on pair production in spatially inhomogeneous frequency chirping electric fields
Melike Mohamedsedik, Lie-Juan Li, Li Wang +3
Effect of the carrier envelop phase on the electron-positron pair production is studied in spatially inhomogeneous electric field with symmetrical frequency chirping. In high or lo…
Pair production in inhomogeneous electric fields with phase modulation
Li-Na Hu, Orkash Amat, Lie-Juan Li +2
Electron-positron pair production is investigated in spatial inhomogeneous electric fields with high or/and low central frequency as well as sinusoidal phase modulation. It is foun…
Schwinger pair production rate and time for some space-dependent electromagnetic fields via worldline instantons formalism
Orkash Amat, Li-Na Hu, Adiljan Sawut +3
Schwinger pair production in some of space-dependent electromagnetic fields is studied analytically by using worldline instantons formalism for scalar quantum electrodynamics. With…

Orkash Amat, Michał Czakon, Sayipjamal Dulat +9
Detailed studies have been carried out on the impact of the LHC top quark pair production data on gluon PDF, in the context of the CTEQ-TEA global PDF fit, with the ePump-updating…
