Exploring the Charge Density Wave phase of 1-TaSe: Mott or Charge-transfer Gap?
C. J. Sayers, G. Cerullo, Y. Zhang +8
1-TaSe is widely believed to host a Mott metal-insulator transition in the charge density wave (CDW) phase according to the spectroscopic observation of a band gap that exte…
Spectroscopic view of ultrafast charge carrier dynamics in single- and bilayer transition metal dichalcogenide semiconductors
P. Majchrzak, K. Volckaert, A. G. Cabo +24
The quasiparticle spectra of atomically thin semiconducting transition metal dichalcogenides (TMDCs) and their response to an ultrafast optical excitation critically depend on inte…
Hot carrier-assisted switching of the electron-phonon interaction in 1-VSe
Paulina Majchrzak, Sahar Pakdel, Deepnarayan Biswas +20
We apply an intense infrared laser pulse in order to perturb the electronic and vibrational states in the three-dimensional charge density wave material 1-VSe. Ultrafast sna…
Ultrafast triggering of insulator-metal transition in two-dimensional VSe
Deepnarayan Biswas, Alfred J. H. Jones, Paulina Majchrzak +24
Assembling transition metal dichalcogenides (TMDCs) at the two-dimensional (2D) limit is a promising approach for tailoring emerging states of matter such as superconductivity or c…
Momentum-resolved linear dichroism in bilayer MoS
Klara Volckaert, Habib Rostami, Deepnarayan Biswas +19
Inversion-symmetric crystals are optically isotropic and thus naively not expected to show dichroism effects in optical absorption and photoemission processes. Here, we find a stro…
Optical Parametric Amplification of Mid-Infrared Few-Cycle Pulses
Adam S Wyatt, Paloma Matía-Hernando, Allan S Johnson +8
We describe Ti:Sapphire pumped optical parametric amplification of carrier-envelope phase stabilized few-cycle (fs) mid-infrared pulses in type I -barium borate. Experiment…
