Coherent perfect absorption mediated anomalous reflection and refraction

We show bending of light on the same side of the normal in a free-standing corrugated metal film under bidirectional illumination. Coherent perfect absorption (CPA) is exploited to suppress the specular zeroth order leading to effective back-bending of lig ...

Tunneling conductivity in composites of attractive colloids

Peter Ryser, Claudio Grimaldi, Biagio Nigro

In conductor-insulator nanocomposites in which conducting fillers are dispersed in an insulating matrix, the electrical connectedness is established by inter-particle tunneling or hopping processes. These systems are intrinsically non-percolative and a coh ...

The physics behind free electron lasers (FELs) based on magnetostatic and optical undulators

Giorgio Margaritondo, Primoz Rebernik Ribic

By explicitly writing the equations of motion for highly relativistic electrons in an electromagnetic field we show the equivalence between the magnetostatic and optical (laser) undulator-based free electron lasers (FELs). In order to gain insight into the ...

Phonon dynamics in CuxBi2Se3 (x=0, 0.1, 0.125) and Bi2Se2 crystals studied using femtosecond spectroscopy

Jia Liu, Helmuth Berger

Phonon dynamics in Bi, Bi2Se2, and CuxBi2Se3 (x=0, 0.1, 0.125) single crystals was investigated using femtosecond pump-probe spectroscopy. Two damped oscillations in measured transient reflectivity changes were observed, respectively, attributed to coheren ...

Penrose-Onsager Criterion Validation in a One-Dimensional Polariton Condensate

Benoît Marie Joseph Deveaud, Konstantinos Lagoudakis, Francesco Manni

We perform quantum tomography on one-dimensional polariton condensates, spontaneously occurring in linear disorder valleys in a CdTe planar microcavity sample. By the use of optical interferometric techniques, we determine the first-order coherence functio ...

Coherent oscillations between polariton vortex and anti-vortex states in an elliptical resonator

Benoît Marie Joseph Deveaud, Gaël Nardin, François Morier-Genoud, Barbara Pietka

In this experimental work, we optically excite the eigenmodes of an elliptical resonator in a semiconductor micro-cavity. Using a pulsed excitation, we create a superposition of eigenmodes, and image the time evolution of the coherent emission pattern. Osc ...

Coherent oscillations between orbital angular momentum polariton states in an elliptic resonator

Benoît Marie Joseph Deveaud, Gaël Nardin, François Morier-Genoud, Barbara Pietka

We optically excited the eigenmodes of an elliptic resonator in a semiconductor microcavity. Using a pulsed excitation, we created a superposition of eigenmodes, and imaged the temporal evolution of the coherent emission pattern. A semiconductor quantum we ...

Observation of D+ -> K+eta(()'()) and Search for CP Violation in D+ -> pi(+)eta(()'()) Decays

Olivier Schneider, Yiming Li, Aurelio Bay, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Jun Yong Kim, Remi Léandre Albert Louvot, Ji Hyun Kim, Jing Li

We report the first observation of the doubly Cabibbo-suppressed decays D+ -> K+eta(()'()) using a 791 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The ratio of the branching fractions of doubly Cabi ...

Polariton lasing in a hybrid bulk ZnO microcavity

Nicolas Grandjean, Raphaël Butté, Jacques Levrat, Georg Rossbach

We demonstrate polariton lasing in a bulk ZnO planar microcavity under non-resonant optical pumping at a small negative detuning (delta similar to -1/6 the 130 meV vacuum Rabi splitting) and a temperature of 120 K. The strong coupling regime is maintained ...
