PMID: 37945698
Optically driven quantum materials exhibit a variety of non-equilibrium functional phenomena, which to date have been primarily studied with ultrafast optical, X-Ray and photo-emission spectroscopy. However, little has been done...

Nature
. 2023 May;
617(7959):73-78.
PMID: 37138109
In quantum materials, degeneracies and frustrated interactions can have a profound impact on the emergence of long-range order, often driving strong fluctuations that suppress functionally relevant electronic or magnetic phases....

Proc Natl Acad Sci U S A
. 2022 Sep;
119(39):e2211670119.
PMID: 36126100
The interplay between charge order and superconductivity remains one of the central themes of research in quantum materials. In the case of cuprates, the coupling between striped charge fluctuations and...

Science
. 2019 Jun;
364(6445):1075-1079.
PMID: 31197010
Fluctuating orders in solids are generally considered high-temperature precursors of broken symmetry phases. However, in some cases, these fluctuations persist to zero temperature and prevent the emergence of long-range order....

Proc Natl Acad Sci U S A
. 2018 Nov;
115(48):12148-12151.
PMID: 30429325
We use coherent midinfrared optical pulses to resonantly excite large-amplitude oscillations of the Si-C stretching mode in silicon carbide. When probing the sample with a second pulse, we observe parametric...

PMID: 30118273
The ultrafast dynamics of the octahedral rotation in Ca:SrTiO_{3} is studied by time-resolved x-ray diffraction after photoexcitation over the band gap. By monitoring the diffraction intensity of a superlattice reflection...

555(7694):79-82.
PMID: 29466328
Nonlinear optical techniques at visible frequencies have long been applied to condensed matter spectroscopy. However, because many important excitations of solids are found at low energies, much can be gained...

Science
. 2018 Feb;
359(6375):575-579.
PMID: 29420290
Unconventional superconductivity in the cuprates coexists with other types of electronic order. However, some of these orders are invisible to most experimental probes because of their symmetry. For example, the...
