Floquet-Bloch Dynamics in Simple Systems
ORAL
Abstract
Fascinating changes in electronic properties such as topological and other phase
transitions of materials can be realized by periodically driving them using external fields.
Floquet-Bloch theory can reveal interesting signatures pertaining to above transitions.
By periodically driving the electronic states of one- and two-dimensional systems,
we obtain numerical solutions, without having to resort to a high frequency expansion.
Some of the important aspects of the above transitions will be discussed and
these ideas will be extended to small cluster-based systems with many-electron interactions.
