Real-time dynamics of the two-step charge-density-wave transition in bulk 1T-TaS
Daeheon Kim, Jinseok Oh, Kahyeon Koh +4
The charge-density wave (CDW) of bulk 1T-TaS2 is built from Star-of-David (SoD) clusters tiling a sqrt{13} x sqrt{13} superlattice, and it melts through a two-step sequence accompa…
Light-induced ideal Weyl semimetal in HgTe via nonlinear phononics
Dongbin Shin, Angel Rubio, Peizhe Tang
Interactions between light and matter allow the realization of out-of-equilibrium states in quantum solids. In particular, nonlinear phononics is one of the efficient approaches to…
Dynamics of electronic states in the insulating Intermediate surface phase of 1T-TaS

Here we perform angle and time-resolved photoelectron spectroscopy on the commensurate Charge Density Wave (CDW) phase of 1T-TaS. Data with different probe pulse polarization a…
Simulating terahertz field-induced ferroelectricity in quantum paraelectric SrTiO
Dongbin Shin, Simone Latini, Christian Schafer +5
Recent experiments have demonstrated that light can induce a transition from the quantum paraelectric to the ferroelectric phase of SrTiO. Here, we investigate this terahertz f…

High Harmonic Generation (HHG), which has been widely used in atomic gas, has recently expanded to solids as a means to study highly nonlinear electronic response in condensed matt…
Identification of the Mott insulating CDW state in 1T-TaS
Dongbin Shin, Nicolas Tancogne-Dejean, Jin Zhang +3
We investigate the low-temperature charge-density-wave (CDW) state of bulk TaS with a fully self-consistent DFT+U approach, over which the controversy has remained unresolved r…
The Ferroelectric Photo-Groundstate of SrTiO: Cavity Materials Engineering
Simone Latini, Dongbin Shin, Shunsuke A. Sato +4
Optical cavities confine light on a small region in space which can result in a strong coupling of light with materials inside the cavity. This gives rise to new states where quant…
