Analogue Penrose process in rotating acoustic black Hole
Decheng Ma, Enrique Solano, Chenglong Jia +1
Analogue gravity stands today as an important tool for the investigation of gravitational phenomena that would be otherwise out of reach considering our technology. We consider her…
Analogue gravitational lensing in optical Bose-Einstein condensates
Decheng Ma, Chenglong Jia, Enrique Solano +1
We consider acoustic propagation of phonons in the presence of a non-rotating vortex with radial flow in a Bose-Einstein condensate (BEC) of photons. Since the vortex can be used t…
Twisting and tweezing the spin wave: on vortices, skyrmions, helical waves, and the magnonic spiral phase plate
Chenglong Jia, Decheng Ma, Alexander F. Schäffer +1
Spin waves are the low-energy excitations of magnetically ordered materials. They are key elements in the stability analysis of the ordered phase and have a wealth of technological…
Square wave oscillation of soliton in double-well potential trapped BEC
Decheng Ma, Chenglong Jia
We numerically investigate the soliton tunnelling process in double-well potential trapped Bose-Einstein condensate. Comparing with the usual low energy few particle tunnelling pro…
One dimensional Cherenkov processes in ferromagnetic insulator
Tongli Wei, YaoJin Li, DeCheng Ma +1
One dimensional Cherenkov processes in ferromagnetic isolators are studied with perturbation theory under the constraint condition of conservation of energy and momentum. It is sho…
