Recent progress in utilizing ultrafast light-matter interaction to control the macroscopic
properties of quantum materials is reviewed. Particular emphasis is placed on photoinduced …

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

In recent years, the notion of'Quantum Materials' has emerged as a powerful unifying
concept across diverse fields of science and engineering, from condensed-matter and …

This article reviews the static and dynamic properties of spontaneous superstructures
formed by electrons. Representations of such electronic crystals are charge density waves …

Ultrafast responses of BCS superconductor Nb 1-x Ti x N films in a nonadiabatic excitation
regime were investigated by using terahertz (THz) pump-THz probe spectroscopy. After an …

One of the great dream experiments in Science is to directly observe atomic motions as they
occur. Femtosecond electron diffraction provided the first'light'of sufficient intensity to …

Abstract Intense femtosecond (10− 15 s) light pulses can be used to transform electronic,
magnetic and structural order in condensed-matter systems on timescales of electronic and …

Upon excitation with an intense laser pulse, a symmetry-broken ground state can undergo a
non-equilibrium phase transition through pathways different from those in thermal …

Macroscopic quantum phenomena such as high-temperature superconductivity, colossal
magnetoresistance, ferrimagnetism and ferromagnetism arise from a delicate balance of …

This review provides a comprehensive overview of current research on the structural,
electronic, and magnetic characteristics of the recently discovered high-temperature …
