The recent development of ultrashort laser pulses allows for optical control of structural and
electronic properties of complex quantum materials. The layered transition-metal …

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 …

We report our theoretical results on the order parameters for the pyrochlore metal Cd 2 Re 2
O 7, which undergoes enigmatic phase transitions with inversion symmetry breaking. By …

The information content of crystalline materials becomes astronomical when collective
electronic behavior and their fluctuations are taken into account. In the past decade …

In the presence of electron-phonon coupling, an excitonic insulator harbors two degenerate
ground states described by an Ising-type order parameter. Starting from a microscopic …

Far from equilibrium phenomenon is a central theme of contemporary material research.
Such phenomenon can exhibit itself in atomic structure and dynamics, but very often it also …

We show the ferro-rotational nature of the commensurate charge density wave (CCDW) in 1
T-TaS 2 and track its dynamic modulations by temperature-dependent and time-resolved …

The pyrochlore oxides O 7 exhibit a complex interplay between geometrical frustration,
electronic correlations, and spin–orbit coupling (SOC), due to the lattice structure and active …
