Critical photoinduced reflectivity relaxation dynamics in single-layer Bi-based cuprates near the pseudogap end point
T. Shimizu, R. Tobise, T. Kurosawa +6
A comprehensive study of photoinduced transient reflectivity dynamics in heavily overdoped single-layer cuprate (Bi,Pb)SrCuO (Pb-Bi-2201) across the end points…
Incommensurate Chiral CDW in -VSe
Y. Sugawara, A. Nomura, Y. Toda +5
We have investigated the chiral charge-density wave (CDW) in -VSe using scanning tunneling microscopy (STM) measurements and optical polarimetry measurements. With the STM…
Dynamics of the superconducting order parameter through ultrafast normal-to-superconducting phase transition in BiSrCaCuO from multi-pulse polarization-resolved transient optical reflectivity
I. Madan, V. V. Baranov, Y. Toda +5
A systematic temperature dependent study of the femtosecond optical superconducting (SC) state destruction and recovery in BiSrCaCuO cuprate superconducto…
Analysis of the Pancharatnam-Berry phase of vector vortex states using the Hamiltonian based on the Maxwell-Schrödinger equation
Masato Suzuki, Keisaku Yamane, Kazuhiko Oka +2
We derived the Berry connection of vector vortex states (VVSs) from the "true" Hamiltonian obtained through the Maxwell--Schrödinger equation for an inhomogeneous anisotropic (IA)…
Comment on "Higher Order Pancharatnam-Berry Phase and the Angular Momentum of Light"
Masato Suzuki, Keisaku Yamane, Kazuhiko Oka +2
In a recent letter, Milione et al. reported the Pancharatnam-Berry phase (PBP) on a higher-order Poincaré sphere (HOPS) [Phys. Rev. Lett, 108, 190401 (2012)]. They used two spin-or…
Strain-induced enhancement of the electron energy relaxation in strongly correlated superconductors
C. Gadermaier, V. V. Kabanov, A. S. Alexandrov +12
We use femtosecond optical spectroscopy to systematically measure the primary energy relaxation rate k1 of photoexcited carriers in cuprate and pnictide superconductors. We find th…
Unifying explanation for carrier relaxation anomaly in gapped systems
Shota Ono, Hiroyuki Shima, Yasunori Toda
We develop a theory to describe energy relaxation of photo-excited carriers in low-temperature ordered states with band gap opening and formulate carrier relaxation time near a…
Mechanisms of nonthermal destruction of the superconducting state and melting of the charge-density-wave state by femtosecond laser pulses
L. Stojchevska, P. Kusar, T. Mertelj +4
The processes leading to nonthermal condensate vaporization and charge-density wave (CDW) melting with femtosecond laser pulses is systematically investigated in different material…
Chiral charge-density-waves
J. Ishioka, Y. H. Liu, K. Shimatake +5
We discovered the chirality of charge density waves (CDW) in 1T-TiSe by using scanning tunnelling microscopy (STM) and optical ellipsometry. We found that the CDW intensity bec…
Optical diffraction spectroscopy of excitons in uniaxially-strained GaN films
Y. Toda, S. Adachi, Y. Abe +2
The degenerate four-wave mixing spectroscopy of uniaxially strained GaN layers is demonstrated using colinearly polarized laser pulses. The nonlinear response of FWM signal on exci…
