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…
Combined visible and near-infrared OPA for wavelength scaling experiments in strong-field physics
David T. Lloyd, Kevin O'Keeffe, Adam S. Wyatt +3
We report the operation of an optical parametric amplifier (OPA) capable of producing gigawatt peak-power laser pulses with tunable wavelength in either the visible or near-infrare…
Interferometric method for the complete characterization of highly chirped ultrabroadband pulses
Adam S Wyatt, Pedro Oliveira, Ian O Musgrave
This article describes an interferometric method, called "Chirped Heterodyne Interferometry for Measuring Pulses" (CHIMP), for the complete characterization of highly (monotonicall…
Frequency-resolved optical gating of highly chirped ultrabroadband pulses
Adam S Wyatt, Pedro Oliveira, Ian O Musgrave
This article describes a simplified reconstruction algorithm for frequency resolved optical gating (FROG) measurements of highly (monotonically) chirped pulses. The FROG traces are…
Spectral-gap immune characterization of electric fields
Ilaria Gianani, Charles Bourassin-Bouchet, Patrick N. Anderson +4
Synthesised light sources need reliable diagnostics for effective application to sub-femtosecond control and probing. However, commonly employed self-referencing techniques for pul…
Vectorial Phase Retrieval for Linear Characterization of Attosecond Pulses
Oren Raz, Osip Schwartz, Dane Austin +7
The waveforms of attosecond pulses produced by high-harmonic generation carry information on the electronic structure and dynamics in atomic and molecular systems. Current methods…
Measuring sub-Planck structural analogues in chronocyclic phase space
Dane R. Austin, Tobias Witting, Ian A. Walmsley
The phase space structure of certain quantum states reveals structure on a scale that is small compared to the Planck area. Using an analog between the wavefunction of a single pho…
