Lower bounds on concurrence and negativity from a trace inequality
K. V. Antipin
For bipartite quantum states we obtain lower bounds on two important entanglement measures, concurrence and negativity, studying the inequalities for the expectation value of a pro…

Bosonic bright soliton in the mixture of repulsive Bose-Einstein condensate and polarized ultracold fermions under influence of the pressure evolution
Pavel A. Andreev, K. V. Antipin, Mariya Iv. Trukhanova
Repulsive Bose-Einstein condensate, where the short-range interaction is included up to the third order by the interaction radius, demonstrates existence of a bright soliton in a n…
