<span style="color:#1F497D">today</span> at 11:30am in 1080 Smith Seminar, PRB. Learn more about Dr. Vishik’s seminar topic "Ultrafast dynamics in the presence of antiferromagnetic correlations in electron-doped cuprates" below. Thank you and we look forward
to seeing you soon!<o:p></o:p></p>

<p class="MsoNormal"><u>Abstract<o:p></o:p></u></p>
<p class="MsoNormal">Electron-doped cuprates represent an interesting bridge system between hole-doped cuprate high-temperature superconductors and other unconventional superconductors such as iron-based and heavy fermion superconductors. Like the latter systems,
electron-doped cuprates feature close proximity between antiferromagnetism and superconductivity on the phase diagram, but they manifest this physics on the copper-oxygen planes which they share with the hole-doped cuprates. One enduring question on the electron-doped
side of the phase diagram, is the degree to which the regime of antiferromagnetism constitutes static order, and ultrafast spectroscopies, which can access picosecond and sub-picosecond timescales are natural tools to explore this issue. To this end, we have
used femtosecond optical pump-probe spectroscopy to study the dynamics of antiferromagnetic correlations via the photoinduced change in reflectivity of thin films of the electron-doped cuprate La2-xCexCuO4 (LCCO). I will show how we use these time-domain experiments
to learn about coupling between electrons and high-energy (> 2ΔAF ) excitations in these compounds and set limits on the timescales on which antiferromagnetic correlations are static.<o:p></o:p></p>
