Time delay in photoemission by attosecond laser pulses

TL;DR

This paper links observed attosecond photoemission time delays to hyperbolic quantum heat transport, proposing a new local Schrödinger equation with finite c to explain the phenomenon.

Contribution

It introduces a hyperbolic heat transport framework to describe attosecond photoemission delays and generalizes quantum mechanics with a finite c local Schrödinger equation.

Findings

Time delay of 20 as corresponds to thermal relaxation time.

Hyperbolic heat transport explains the observed delay.

Proposes a new local Schrödinger equation with finite c.

Abstract

Recently the time delay in the attosecond photoemission was observed (Science,2010). In this paper we propose the description of that time delay in the framework of hyperbolic heat transport equation. We argue that the observed time delay 20 as is of the order of the thermal relaxation time for hyperbolic quantum heat transport. As the generalization of the standard quantum mechanics we propose new local Schroedinger equation with c=finite
