Wave optics of quantum gravity for massive particles
S. L. Cherkas, V. L. Kalashnikov
Effects of the quantum gravity under Minkowski space-time background are considered. It is shown that despite the absence of the complete theory of quantum gravity, some concrete p…
A "metaphorical" nonlinear multimode fiber laser approach to weakly-dissipative Bose-Einstein condensates
V. L. Kalashnikov, S. Wabnitz
We demonstrate the stabilization of two-dimensional nonlinear wave patterns by means of a dissipative confinement potential. Our analytical and numerical analysis, based on the gen…
Illusiveness of the problem of time
Sergey L. Cherkas, Vladimir L. Kalashnikov
The essay is devoted to the problem of time in the context of quantum cosmology, which acquires a philosophical level to date. At an example of the minisuperspace model, we show th…
Distributed Kerr-Lens Mode-Locking Based on Spatiotemporal Dissipative Solitons in Multimode Fiber Lasers
Vladimir L. Kalashnikov, Stefan Wabnitz
We introduce a mechanism of stable spatiotemporal soliton formation in a multimode fiber laser. This is based on spatially graded dissipation, leading to distributed Kerr-lens mode…
Evidence of time evolution in quantum gravity
S. L. Cherkas, V. L. Kalashnikov
We argue that the problem of time is not a crucial issue inherent in the quantum picture of the universe evolution. On the minisuperspace model example with the massless scalar fie…
Sub-surface modifications in silicon with ultrashort pulsed lasers above 2 microns
Roland A. Richter, Nikolai Tolstik, Sebastien Rigaud +7
Nonlinear optical phenomena in silicon such as self-focusing and multi-photon absorption are strongly dependent on the wavelength, energy and duration of the exciting pulse. Thus,…
