Probing quantum nonlinear phononics in multilayer graphene with time-resolved Raman scattering
Jakob Dolgner, Michael Rübhausen, Dirk Manske
Coherently driven phonons are conventionally described classically. Nonlinear phonon-phonon interactions, however, allow an infrared drive to reshape the fluctuation spectrum and g…
Direct observation of the Higgs particle in a superconductor by non-equilibrium Raman scattering
Tomke E. Glier, Sida Tian, Mika Rerrer +12
Even before its role in electroweak symmetry breaking, the Anderson-Higgs mechanism was introduced to explain the Meissner effect in superconductors. Spontaneous symmetry-breaking…
Optically Induced Avoided Crossing in Graphene
Sören Buchenau, Benjamin Grimm-Lebsanft, Florian Biebl +8
Degenerate states in condensed matter are frequently the cause of unwanted fluctuations, which prevent the formation of ordered phases and reduce their functionalities. Removing th…
Unravelling local spin polarization of Zhang-Rice singlet in lightly hole-doped cuprates using high-energy optical conductivity
Iman Santoso, Wei Ku, Tomonori Shirakawa +11
Unrevealing local magnetic and electronic correlations in the vicinity of charge carriers is crucial in order to understand rich physical properties in correlated electron systems.…
Emerging giant resonant exciton induced by Ta-substitution in anatase TiO: a tunable correlation effect
Z. Yong, P. E. Trevisanutto, L. Chiodo +11
Titanium dioxide (TiO) has rich physical properties with potential implications in both fundamental physics and new applications. Up-to-date, the main focus of applied research…
Temperature-dependent and anisotropic optical response of layered PrCaMnO probed by spectroscopic ellipsometry
M. A. Majidi, E. Thoeng, P. K. Gogoi +9
We study the temperature dependence as well as anisotropy of optical conductivity () in the pseudocubic single crystal PrCaMnO using spectrocopic ellipso…

T. C. Asmara, A. Annadi, I. Santoso +9
In condensed matter physics the quasi two-dimensional electron gas at the interface of two different insulators, polar LaAlO3 on non-polar SrTiO3 (LaAlO3/SrTiO3) is a spectacular a…
Large spectral weight transfer in optical conductivity of SrTiO induced by intrinsic vacancies
Teguh C. Asmara, Xiao Wang, Iman Santoso +11
The optical conductivity () of SrTiO for various vacancies has been systematically studied using a combination of ultraviolet - vacuum ultraviolet (UV-VUV) reflectivit…

A new excitation is observed at 201 meV in the doped-hole ladder cuprate SrCuO, using ultraviolet resonance Raman scattering with incident light at 3.7 eV pola…
Two component dynamics of the superconducting order parameter revealed by time-resolved Raman scattering
R. P. Saichu, I. Mahns, A. Goos +10
We study the dynamics of the superconducting order parameter in the high- cuprate BiSrCaCuO by employing a novel time-resolved pump-probe Raman experiment.…

Anomalous Self-Energy Effects of the B_1g Phonon in Y_{1-x}(Pr,Ca)_xBa_2Cu_3O_7 Films
A. Bock, S. Ostertun, R. Das Sharma +2
In Raman spectra of cuprate superconductors the gap shows up both directly, via a redistribution of the electronic background, the so-called "2Delta peaks", and indirectly, e.g. vi…
