Dynamics of competing orders in YBCO triggered by ultrafast light pulses — •Junichi Okamoto, Robert Höppner, Beilei Zhu, and Ludwig Mathey — Institute for Laser Physics, University of Hamburg, Hamburg, Germany
In the emerging field of optically driven strongly correlated systems, laser-excited high-Tc cuprates are one of the most fascinating topics. In equilibrium, the underdoped region of high-Tc cuprates exhibit various competing orders, e.g., stripes, density-waves and superconductivity. In this talk, we will explore the possibility of optically controlling such competing orders. In particular, we will focus on the underdoped region of YBCO, where d-wave superconductivity and charge-density waves coexist. We will present preliminary results of numerical simulations of optically driven competing orders in the material.
