Separating pairing from quantum phase coherence dynamics above the superconducting transition by femtosecond spectroscopy
Ivan Madan, Toru Kurosawa, Yasunori Toda +4
In classical superconductors an energy gap and phase coherence appear simultaneously with pairing at the transition to the superconducting state. In high-temperature superconductor…
Ultrafast switching to a stable hidden topologically protected quantum state in an electronic crystal
L. Stojchevska, I. Vaskivskyi, T. Mertelj +4
Hidden states of matter with novel and unusual properties may be created if a system out of equilibrium can be induced to follow a trajectory to a state which is inaccessible or do…
Analysis of damping-induced phase flips of plasmonic nanowire modes
Andreas Hohenau, Primoz Kusar, Christian Gruber +1
We launch surface plasmons from one end of a silver nanowire by asymmetric illumination with white light and use plasmon-to-light scattering at the nanowire ends to probe spectrosc…
Incoherent topological defect recombination dynamics in TbTe_3
T. Mertelj, P. Kusar, V. V. Kabanov +2
We study the incoherent recombination of topological defects created during a rapid quench of a charge-density-wave system through the electronic ordering transition. Using a speci…
Real time measurement of the emergence of superconducting order in a high temperature superconductor
I. Madan, P. Kusar, V. V. Baranov +4
Systems which rapidly evolve through symmetry-breaking transitions on timescales comparable to the fluctuation timescale of the single-particle excitations may behave very differen…
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…
Coherent dynamics of macroscopic electronic order through a symmetry-breaking transition
R. Yusupov, T. Mertelj, V. V. Kabanov +5
The temporal evolution of systems undergoing symmetry breaking phase transitions (SBTs) is of great fundamental interest not only in condensed matter physics, but extends from cosm…
Nonlinear order parameter oscillations and lattice coupling in strongly-driven charge-density-wave systems
P. Kusar, T. Mertelj, V. V. Kabanov +4
The anharmonic response of charge-density wave (CDW) order to strong laser-pulse perturbations in 1T-TaS_2 and TbTe_3 is investigated by means of a multiple-pump-pulse time-resolve…
Electron-phonon coupling and charge gap in spin-density-wave iron-pnictides from quasiparticle relaxation dynamics
L. Stojchevska, P. Kusar, T. Mertelj +5
We investigate the quasiparticle relaxation and low-energy electronic structure in undoped SrFe_2As_2 exhibiting spin-density wave (SDW) ordering using optical pump-probe femtoseco…
Quasiparticle relaxation dynamics in spin-density-wave and superconducting SmFeAsO_{1-x}F_{x} single crystals
T. Mertelj, P. Kusar, V. V. Kabanov +7
We investigate the quasiparticle relaxation and low-energy electronic structure in undoped SmFeAsO and near-optimally doped SmFeAsO_{0.8}F_{0.2} single crystals - exhibiting spin-d…
Electron-Phonon Coupling in High-Temperature Cuprate Superconductors Determined from Electron Relaxation Rates
C. Gadermaier, A. S. Alexandrov, V. V. Kabanov +7
We determined electronic relaxation times via pump-probe optical spectroscopy using sub-15 fs pulses for the normal state of two different cuprate superconductors.We show that the…
Controlled vaporization of the superconducting condensate in cuprate superconductors sheds light on the pairing boson
P. Kusar, V. V. Kabanov, S. Sugai +3
We use ultrashort intense laser pulses to study superconducting state vaporization dynamics in La(2-x)Sr(x)CuO4 (x=0.1 and 0.15) on the femtosecond timescale. We find that the ener…
