The Large Hadron Collider beauty (LHCb) collaboration today announced results that confirm the existence of exotic hadrons – a type of matter that cannot be classified within the traditional quark mod...
The Existence of Quantum Entanglement Catalysts.
Entanglement catalysts entanglement states entanglement
2012/11/29
Without additional resources, it is often impossible to transform one entangled quantum state into another with local quantum operations and classical communication. Jonathan and Plenio (Phys. Rev. Le...

Evidence Shape Co-existence medium spin 76Rb
2011/7/21
Four previously known rotational bands in 76Rb have been extended to moderate spins using the Gammasphere and Microball gamma ray and charged particle detector arrays and the 40Ca(40Ca,3pn) reaction a...
On the Existence of a Self-Similar Coarse Graining of a Self-Similar Space
self-similar set fractals dynamical system Cantor set coarse graining
2011/7/21
Abstract: A topological space homeomorphic to a self-similar space is demonstrated to be self-similar. There exists a self-similar space $S$ whose coarse graining is homeomorphic to $S$. The coarse gr...
Deriving the existence of $B\bar{B}^*$ bound states from the X(3872) and Heavy Quark Symmetry
Deriving the existence Heavy Quark Symmetry
2011/7/21
We discuss the possibility and the description of bound states between $B$ and $\bar{B}^*$ mesons. We argue that the existence of such a bound state can be deduced from (i) the weakly bound X(3872) st...

2011/7/1
Abstract: We prove the existence of electrically and magnetically charged particlelike static solutions, known as dyons, in the minimally gauged Skyrme model developed by Brihaye, Hartmann, and Tchrak...
Uniform existence of the integrated density of states on metric Cayley graphs

2011/6/28
Abstract: Given a finitely generated amenable group we consider ergodic random Schr\"odinger operators on a Cayley graph with random potentials and random boundary conditions. We show that the normali...

Existence of vertical spin stiffness ferromagnetic semiconductors
2010/11/4
We calculate the magnetization torque due to the spin polarization of the itinerant electrons by deriving the kinetic spin Bloch equations based on the s-d model. We find that the first-order gradient...
