Condensed Matter Seminar (News&Views series): Thursday 11 February 2021 at 11:00 am

Virtual - Zoom Meeting

CMSP News & Views Seminar
/
/
/The News & Views Seminars are meant to address our section as a whole, 
and therefore include an extensive pedagogical introduction to the 
topic, and present the main physical ideas of the research in a way 
understandable by everybody in the section. The goal is to bridge 
distances among different subgroups of our diverse CMSP section. //The 
diversity in our section makes it a unique place for crossing bridges 
among different topics, and for cross-fertilization among seemingly 
distant fields. /

_Abstract_:

Scientists have always dealt with higher-dimensional wonderlands. The 
contemporary field of topological condensed matter similarly deals with 
systems of arbitrary dimensions. With modern technology, synthetic 
dimensions can nowadays be quantum engineered in the lab. Thus, for the 
first time, we could proposed and realize signatures of high-dimensional 
Hall effects in experiments.

In my talk, I will introduce the close relationship between the 2D 
quantum Hall effect and 1D topological pumps, where the pump parameters 
acts as a synthetic dimension. I will, then, present experimental 
realizations of topological pumps using two completely different bosonic 
systems, namely, using coupled photonic waveguide arrays and with 
trapped atoms in optical superlattices. In the second part of my talk, I 
will present how this naturally leads to the realization of the 4D and 
6D quantum Hall effects, using correspondingly 2D and 3D topological 
pumps. Last, I will detail that the connection between topological pumps 
and higher-dimensional quantum Hall models offers a natural 
interpretation for high-order topological insulators.
