hidden symmetry breaking in strongly correlated matter
to a microscopic understanding of strongly correlated materials is a
picture of the relationship between their myriad quantum
However, in phenomena ranging from unconventional magnetism to high
superconductivity, this picture is often obscured by
the presence of
broken symmetries hidden from view of existing experimental techniques.

come in and
out of existence on ultrashort timescales, invisible to static probes.

reveal hidden symmetry breaking in some of the most intensely
strongly correlated materials of the past decade, including
high-temperature superconductors, spin-orbit coupled transition metal
and heavy fermion materials, and I will discuss how the newly
