C. T. Howells, K. Marbou, H. Kim +20
We demonstrate that blending fluorinated molecules in PEDOT:PSS hole transport layers (HTL) induces charge transfers which impact on both charge extraction and photogeneration with…
Splitting of interlayer shear modes and photon energy dependent anisotropic Raman response in -layer ReSe and ReS
Etienne Lorchat, Guillaume Froehlicher, Stéphane Berciaud
We investigate the interlayer phonon modes in -layer rhenium diselenide (ReSe) and rhenium disulfide (ReS) by means of ultralow-frequency micro-Raman spectroscopy. These…
Frequency non-reciprocity of surface spin wave in Permalloy thin films
O. Gladii, M. Haidar, Y. Henry +2
Surface spin waves in thin Permalloy films are studied by means of propagative spin wave spectroscopy. We observe a systematic difference of up to several tens of MHz when comparin…
Multi-state and non-volatile control of graphene conductivity with surface electric fields

Planar electrodes patterned on a ferroelectric substrate are shown to provide lateral control of the conductive state of a two-terminal graphene stripe. A multi-level and on-demand…
Multi-Wave Coherent Control of a Solid State Single Emitter
F. Fras, Q. Mermillod, G. Nogues +6
Coherent control of individual two-level systems (TLSs) is at the basis of any implementation of quantum information. An impressive level of control is now achieved using nuclear,…
Chirped-Frequency Excitation of Gravitationally Bound Ultracold Neutrons
Giovanni Manfredi, Omar Morandi, Lazar Friedland +2
Ultracold neutrons confined in the Earth's gravitational field display quantized energy levels that have been observed for over a decade. In recent resonance spectroscopy experimen…
Effective Theory and Breakdown of Conformal Symmetry in a Long-Range Quantum Chain
Luca Lepori, Davide Vodola, Guido Pupillo +2
We deal with the problem of studying the effective theories and the symmetries of long-range models around critical points. We focus in particular on the Kitaev chain with long-ran…

O. Viyuela, D. Vodola, G. Pupillo +1
We discover novel topological effects in the one-dimensional Kitaev chain modified by long-range Hamiltonian deformations in the hopping and pairing terms. This class of models dis…
Impact of tunnel barrier strength on magnetoresistance in carbon nanotubes
Caitlin Morgan, Maciej Misiorny, Dominik Metten +4
We investigate magnetoresistance in spin valves involving CoPd-contacted carbon nanotubes. Both temperature and bias voltage dependence clearly indicate tunneling magnetoresistance…
