When very large groups have to brainstorm in smaller subgroups, meeting organizers have a choice between two options: (1) Let every subgroup start from scratch, or (2) Let every next subgroup build on the results from the previous subgroup. We refer to these options as the Decathlon and Relay modes of brainstorming respectively. During a case study we investigated which brainstorming mode would...

Third-order susceptibilities are calculated for a Doppler-broadened two-level system. The dependence of fourwave mixing on the angle 0 between the pump and signal fields is studied, and the reflection coefficient is shown to have a narrow field of view that is inversely proportional to the ratio of the Doppler width to the homogeneous linewidth. For the collinear geometry, 0 = 0°, the frequency...

Reflection statistics have not been well studied for optical random media whose mean refractive indices do not match with the refractive indices of their surrounding media. Here, we theoretically study how this refractive index mismatch between a one-dimensional (1D) optical sample and its surrounding medium affects the reflection statistics in the weak disorder limit, when the fluctuation part...

We study the duality between the two dimensional black hole and the sine-Liouville conformal field theories via exact operator quantization of a classical scattering problem. The ideas are first illustrated in Liouville theory, which is dual to itself under the interchange of the Liouville parameter b by 1/b. In both cases, a classical scattering problem does not determine uniquely the quantum ...

The CWKB approach to non-reflecting potential and cosmological implications. Abstract We discuss the method of calculating the reflection coefficient using complex trajectory WKB (CWKB) approximation. This enables us to give an interpretation of non-reflecting nature of the potential under certain conditions and clarify some points, reported incorrectly elsewhere [1] for the potential U (x) = −...
