Nanometre-scale metal tips irradiated by femtosecond laser pulses represent ultrafast
electron sources. The combination of the laser pulse and the tip offers the possibility of …

We explore the nonequilibrium dynamics of a one-dimensional Fermi-Hubbard system as a
sensitive testbed for the capabilities of the time-dependent two-particle reduced density …

Describing time-dependent many-body systems where correlation effects play an important
role remains a major theoretical challenge. In this paper we develop a time-dependent many …

The integrating factor and exponential time differencing methods are implemented and
tested for solving the time-dependent Kohn-Sham equations. Popular time propagation …

An accurate method for time propagation of the coupled Maxwell and time-dependent Kohn-
Sham (TDKS) equation is presented. The new approach uses a simultaneous fourth-order …

Photoemission from nanostructures under strong fields has attracted significant interests in
materials science and optoelectronic applications. Here, we report the extreme nonlinear …

Time-dependent Density Functional Theory (TDDFT) has become successful for its balance
of economy and accuracy. However, the application of TDDFT to large systems or long time …

Ultrashort custom-tailored laser pulses can be employed to observe and control the motion
of electrons in atoms and small molecules on the (sub-) femtosecond time scale. Very …

First-principles simulations were carried out to explore the excited electron dynamics of
graphene nanoribbons (GNRs) under femtosecond laser pulses and an electrostatic field …

We study the properties of electron excitation and emission of a finite carbon nanotube
(CNT) under a linearly polarized femtosecond laser using real-time time-dependent density …
