Quantum Corrections to Synchrotron Radiation from Wave-Packet

TL;DR

This paper investigates quantum effects on synchrotron radiation emitted by a charged wave-packet in a magnetic field, revealing that quantum uncertainties can both suppress and enhance radiation depending on conditions.

Contribution

It provides the first calculation of quantum corrections to synchrotron radiation from a wave-packet, highlighting the role of velocity uncertainty.

Findings

Quantum corrections reduce classical radiation in high-speed, weak-field limit.

Velocity uncertainty can enhance radiation beyond classical predictions.

The study quantifies $O(a0)a0$ quantum effects on radiation energy.

Abstract

We calculate the radiated energy to $O(\hbar)$ from a charged wave-packet in the uniform magnetic field. In the high-speed and weak-field limit, while the non-commutativity of the system reduces the classical radiation, the additional corrections originated from the velocity uncertainty of the wave-packet leads to an enhancement of the radiation.
