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…
Channel-state duality and the separability problem
K. V. Antipin
Separability of quantum states is analyzed with the use of the Choi-Jamiolkowski isomorphism. Spectral separability criteria are derived. The presented approach is illustrated with…
Haag's theorem in S O (1, k) invariant quantum field theory
K. V. Antipin, Yu. S. Vernov, M. N. Mnatsakanova
Generalized Haag's theorem has been proved in S O (1, k) invariant quantum field theory. Apart from the above mentioned k+1 variables there can be arbitrary number of additional co…
