We observed slow moving vortex lattices in NbSe2 using a home built STM at a temperature of
4.2 K and magnetic fields in the range of 250−500 mT. The vortex lattices move coherently at speeds o...
Principle of Maximum Entropy and Ground Spaces of Local Hamiltonians
Principle Maximum Entropy Ground Spaces f Local Hamiltonians

The structure of the ground spaces of quantum systems consisting of local interactions is of fundamental importance to different areas of physics. In this Letter, we present a necessary and sufficient...
Embezzlement States are Universal for Non-Local Strategies
Embezzlement States Universal Non-Local Strategies
2010/10/18
We prove that the family of embezzlement states defined by van Dam and Hayden[26]
is universal for both quantum and classical entangled two-prover non-local games with an arbitrary number of rounds.
Local Persistence and Blocking in the Two-Dimensional Blume-Capel Model
Local Persistence the Two-Dimensional Blume-Capel Model
2010/10/26
In this paper we study the local persistence of the two–dimensional Blume–Capel Model by extending the concept of Glauber dynamics. We verify that for any value of the ratio ® = D=J between anisot...

Local symmetry properties pure 3-qubit states
2010/10/15
Entanglement types of pure states of three spin- 1 2 particles are classified by means of their stabilisers in the group of local unitary transformations. It is shown that the stabiliser is genericall...
