How to explain the localized gap modes in Bose-Einstein condensates?Bose-Einstein condensates (BECs), created in ultracold bosonic atoms and degenerate quantum gases, are a macroscopic quantum phenomenon and are considered as a single particle in mean-filed theory. By preparing the BECs or ultracold atomic gases onto optica...May 18, 2022 -
How to explain the existence and stability of various localized modes in nonlinear fractional systems?From advanced mathematics, we can know that integral calculus is a general formal theory of integral and derivative of integer order. The "fractional integral", was firstly proposed in mathematics half a century ago, it was a theory about fractional integra...May 18, 2022 -
Purely Nonlinear Strategy Helps Researchers find new method to Stabilize the Dark-Soliton StripesDark solitons, which are characterized as localized intensity dips below a continuous wave background, have attracted great attention due to its fascinating property.
At present, the mainstream researches focus on ultracold atoms like Bose-Einstein cond...Apr 29, 2022 -
