Observation of e(+) e(-) -> gamma chi(c1) and search for e(+) e(-) -> gamma chi(c0), gamma chi(c2), and gamma eta(c) at root s near 10.6 GeV at Belle

Olivier Schneider, Yiming Li, Roberto Gargiani, Mingkui Wang, Gaétan Charles Antoine Giriat, Chao Wang, Sun Hee Kim, Tagir Aushev, Timothy Chi Hin Liew, Chang-Hyun Park

Using data samples of 89.5 fb(-1), 711.0 fb(-1), and 121.4 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider at center-of-mass energies 10.52, 10.58, and 10.867 GeV, respectively, we study the exclusive reactions e(+) ...

Search for B- -> mu(-)(nu)over-bar(mu) Decays at the Belle Experiment

Olivier Schneider, Sun Hee Kim, Mingkui Wang, Chao Wang, Tara Nanut, Tagir Aushev, Joo Yeon Kim, Timothy Chi Hin Liew, Chang-Hyun Park, Seyed Sina Mirrazavi Salehian

We report the results of a search for the rare, purely leptonic decay B- -> mu(-)(nu) over bar (mu) performed with a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs, collected near the Upsilon(4S) resonance with the Belle detector at ...

Multivalley engineering in semiconductor microcavities

Hugo Pierre Alexandre Flayac, Timothy Chi Hin Liew

We consider exciton-photon coupling in semiconductor microcavities in which separate periodic potentials have been embedded for excitons and photons. We show theoretically that this system supports degenerate ground-states appearing at non-zero inplane mom ...

Kinetic Monte Carlo approach to nonequilibrium bosonic systems

Timothy Chi Hin Liew, Hugo Pierre Alexandre Flayac

We consider the use of a kinetic Monte Carlo approach for the description of nonequilibrium bosonic systems, taking nonresonantly excited exciton-polariton condensates and bosonic cascade lasers as examples. In the former case, the considered approach allo ...

Spontaneous self-ordered states of vortex-antivortex pairs in a polariton condensate

Benoît Marie Joseph Deveaud, Vincenzo Savona, Timothy Chi Hin Liew, Konstantinos Lagoudakis, Francesco Manni, Claudéric Ouellet-Plamondon

Polariton condensates have proved to be model systems to investigate topological defects, as they allow for direct and nondestructive imaging of the condensate complex order parameter. The fundamental topological excitations of such systems are quantized v ...

Multimode entanglement in coupled cavity arrays

Vincenzo Savona, Timothy Chi Hin Liew

We study a driven-dissipative array of coupled nonlinear optical resonators by numerically solving the von Neumann equation for the density matrix. We demonstrate that quantum correlated states of many photons can also be generated in the limit where the n ...

Dissociation dynamics of singly charged vortices into half-quantum vortex pairs

Benoît Marie Joseph Deveaud, Vincenzo Savona, Timothy Chi Hin Liew, Konstantinos Lagoudakis, Francesco Manni

The quest for identification and understanding of fractional vorticity is a major subject of research in the quantum fluids domain, ranging from superconductors, superfluid Helium-3 to cold atoms. In a two-dimensional Bose degenerate gas with a spin degree ...

Quantum entanglement in nanocavity arrays

Vincenzo Savona, Timothy Chi Hin Liew

We show theoretically how quantum interference between linearly coupled modes with weak local nonlinearity allows the generation of continuous variable entanglement. By solving the quantum master equation for the density matrix, we show how the entanglemen ...

Motion of Spin Polariton Bullets in Semiconductor Microcavities

Timothy Chi Hin Liew

The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied by using time-and spatially resolved spectroscopy. The switching is triggered by polarized short pulses which create spin bullets of high polariton de ...

Suppression of Zeeman Splitting of the Energy Levels of Exciton-Polariton Condensates in Semiconductor Microcavities in an External Magnetic Field

Timothy Chi Hin Liew

A key property of equilibrium exciton-polariton condensates in semiconductor microcavities is the suppression of the Zeeman splitting under a magnetic field. By studying magnetophotoluminescence spectra from a GaAs microcavity, we show experimentally that ...
