On generating r-uniform subspaces with the isometric mapping method
K. V. Antipin
We propose a compositional approach to construct subspaces consisting entirely of r-uniform states, including the ones in heterogeneous systems. The approach allows one to construc…
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…
Properties of collapse dynamics in relativistic theory of gravitation in the case of smooth initial matter distributions
K. V. Antipin, A. I. Dubikovsky, P. K. Silaev
We use both numerical and analytical approaches to study the dynamics of the gravitational collapse in the framework of the relativistic theory of gravitation (RTG). We use various…
LSZ reduction formula in many-dimensional theory with space-space noncommutativity
K. V. Antipin, M. N. Mnatsakanova, Yu. S. Vernov
An analogue of the Lehmann-Symanzik-Zimmermann reduction formula is obtained for the case of noncommutative space-space theory. Some consequences of the reduction formula and Haag'…
Haag's Theorem in the Theories with Non-physical Particles
K. V. Antipin, M. N. Mnatsakanova, Yu. S. Vernov
Haag's theorem is extended to the case of regular representations of the canonical commutation relations in a non-degenerate indefinite inner product space.
Extension of von Neumann's uniqueness theorem to the theories with non-physical particles
K. V. Antipin, M. N. Mnatsakanova, Yu. S. Vernov
Von Neumann's uniqueness theorem is extended to a special class of canonical commutation relations, namely the anti-Fock representations, which are realized on a Krein space.
Haag's Theorem in Noncommutative Quantum Field Theory
K. V. Antipin, M. N. Mnatsakanova, Yu. S. Vernov
Haag's theorem was extended to noncommutative quantum field theory in a general case when time does not commute with spatial variables. It was proven that if S-matrix is equal to u…
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…
Two-pion Bose-Einstein correlations in pp collisions at GeV
ALICE Collaboration
We report on the measurement of two-pion correlation functions from pp collisions at GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis…
First proton-proton collisions at the LHC as observed with the ALICE detector: measurement of the charged particle pseudorapidity density at = 900 GeV
ALICE Collaboration
On 23rd November 2009, during the early commissioning of the CERN Large Hadron Collider (LHC), two counter-rotating proton bunches were circulated for the first time concurrently i…
The Baikal Neutrino Telescope: Selected Physics Results
R. Wischnewski
We present results on searches for exotic particles (relativistic magnetic monopoles and WIMPs) and for UHE neutrinos, obtained with the Baikal neutrino telescope NT200.
