Quantum-mechanical phenomena underpin the behaviour of quantum materials at the
microscopic level. The description of several essential properties of these materials …

The advent of intense ultrashort optical pulses spanning a frequency range from terahertz to
the visible has opened a new era in the experimental investigation and manipulation of …

The recent observation of the light-induced superconducting (SC)-like transient response in
c-axis optical conductivity far above the SC transition temperature T c in underdoped Y Ba 2 …

Optical excitation in the cuprates has been shown to induce transient superconducting
correlations above the thermodynamic transition temperature TC, as evidenced by the …

We discuss a systematic error in time-resolved optical conductivity measurements that
becomes important at high pump intensities. We show that common optical nonlinearities …

Nonlinear interactions between phonon modes govern the behavior of vibrationally highly
excited solids and molecules. Here we demonstrate theoretically control over the …

Recent pump-probe experiments on underdoped cuprates and similar systems suggest the
existence of a transient superconducting state above T c. This poses the question of how to …

High-T c cuprate, alkali-doped C 60, and several other unconventional superconductors
have very high transition temperatures T c with respect to the energy scale of …

In cuprate high-T c superconductors, resonant excitation of certain lattice vibrations has
been shown to induce transient terahertz reflectivity features suggestive of nonequilibrium …

We performed a comprehensive study of light-induced superconducting-like responses in La-
based cuprate superconductors, L a 2− x− y N dy S rx Cu O 4, which exhibit charge stripe …
