A connection between the bipartite complements of line graphs and the line graphs with two positive eigenvalues
line graphs graph spectra complements Courant-Weyl inequalities
2012/4/16
In 1974 Cvetkovi\'c and Simi\'c showed which graphs $G$ are the bipartite complements of line graphs. In 2002 Borovi\'canin showed which line graphs $L(H)$ have third largest eigenvalue $\lambda_3\leq...
Abstract: Let \Gamma be the generalized random bipartite graph that has two sides Rl and Rr with edges for every pair of vertices between R1 and Rr but no edges within each side, where all the edges a...
The generalized connectivity of complete bipartite graphs
k-connectivity complete bipartite graph edge-disjoint spanning trees
2011/2/28
Let G be a nontrivial connected graph of order n, and k an integer with 2 ≤k ≤ n. For a set S of k vertices of G, let κ(S) denote the maximum number ℓ of edge-disjoint trees T1, T2, . . . , T...
Cohen-Macaulayness of bipartite graphs, revisited
edge ideal of a graph Cohen-Macaulay bipartite graph
2011/1/17
Cohen-Macaulayness of bipartite graphs is investigated by several mathematicians and has been characterized combinatorially. In this note, we give some different combi-natorial conditions for a bipart...
This note is an Addendum to our previous article [Phys. Rev. A \textbf{81}, 053820 (2010)]. We show that under the assumption of a Bose-Einstein distribution for the thermal reservoir, zero-temperatur...
Bipartite Entanglement in Out-of-equilibrium Correlated Many-body Systems
Bipartite Entanglement Out-of-equilibrium Correlated Many-body Systems
2010/11/19
Relaxation and thermalization after e.g a quantum quench play a central role in out-of-equilibrium physics (e.g. of ultracold atoms) and electronic transport phenomena. On the other hand, entanglement...
Entanglement dynamics of bipartite system in squeezed vacuum reservoirs

2010/11/8
Entanglement plays a crucial role in quantum information protocols, thus the dynamical behavior of entangled states is of a great importance. In this paper we suggest a useful scheme that permits a di...
Entanglement dynamics of two-bipartite system under the influence of dissipative environments
dissipative environments Quantum Physics
2010/11/8
An experimental scheme is suggested that permits a direct measure of entanglement in a two-qubit cavity system. It is realized in the cavity-QED technology utilizing atoms as flying qubits. With this ...
A evolutionary method for finding communities in bipartite networks
evolutionary method bipartite networks
2010/11/16
Common practice in community structure detection is to develop different methods for different classes of networks. Here, we first show that unipartite networks and directed networks can be uniformly...
In this paper we study the generalized version of weighted matching in bipartite networks. Consider a weighted matching in a bipartite network in which the nodes derive value from the split of the ma...

2010/11/8
We compare three different characterizations of the globalness of bipartite unitary operations based on different tasks, namely, delocalization power, entanglement cost for LOCC implementation, and e...
Geometric measure of quantum discord for an arbitrary state of a bipartite quantum system
Geometric measure quantum discord for arbitrary state bipartite quantum system
2010/11/4
Quantum discord, as introduced by Olliver and Zurek [Phys. Rev. Lett. \textbf{88}, 017901 (2001)], is a measure of the discrepancy between quantum versions of two classically equivalent expressions fo...

Deciding Unitary Equivalence Matrix Polynomials Sets of Bipartite Quantum States
2010/10/29
In this brief report, we consider the equivalence between two sets of $m+1$ bipartite quantum states under local unitary transformations. For pure states, this problem corresponds to the matrix algebr...

Entanglement may vanish even for a limited amount of loss imposed on the quantum state, a
phenomenon known as entanglement sudden death in discrete systems, or, as proposed, early stage
disentanglem...
