Raman Induced Visible Stable Platicons and Breather Platicons in Microresonator
We numerically demonstrate that stable platicons and coherent visible Kerr combs can be generated via Raman assisted four wave mixing in a AlN microresonator. Raman induced breather platicon dynamics is also observed in our simulations
Compact graphene mode-locked wavelength-tunable erbium-doped fiber lasers: from all anomalous dispersion towards all normal dispersion
Soliton operation and soliton wavelength tuning of erbium-doped fiber lasers
mode locked with atomic layer graphene was experimentally investigated under
various cavity dispersion conditions. It was shown that not only wide range
soliton wavelength tuning but also soltion pulse width variation could be
obtained in the fiber lasers. Our results show that the graphene mode locked
erbium-doped fiber lasers provide a compact, user friendly and low cost
wavelength tunable ultrahsort pulse source
Lee-Yang Zeros of a Bosonic system associated with a single trapped ion
Zeros of partition functions, in particular Lee-Yang zeros, in a complex
plane provide important information for understanding phase transitions. A
recent discovery on the equivalence between the coherence of a central quantum
system and the partition function of the environment in the complex plane
enabled the experimental study of Lee-Yang zeros, with several pioneering
experiments on spin systems. Lee-Yang zeros have not been observed in Bosonic
systems. Here we propose an experimental scheme to demonstrate Lee-Yang zeros
in Bosonic systems associated with a single trapped ion by introducing strong
coupling between the spin and motion degrees of freedom, i.e. beyond the weak
coupling Lamb-Dicke regime. Our scheme provides new possibilities for quantum
simulation of the thermodynamics of Bosonic systems in the complex plane.Comment: 6 pages,6 figure
