2019/10/23
NSF-funded research by scientists at Brown and Columbia Universities has demonstrated the existence of previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensio...
Local characterization of one-dimensional topologically ordered states
Local characterization one-dimensional topologically ordered states
2016/1/23
We consider one-dimensional Hamiltonian systems whose ground states display symmetry-protected topological order. We show that ground states within the topological phase cannot be connected with each ...

Local Convertibility and Edge States in Quantum Many Body Systems
Local Convertibility Edge States Quantum Many Body Systems
2016/1/22
In some many-body systems, certain ground-state entanglement (Rényi) entropies increase even as the correlation length decreases. This entanglement nonmonotonicity is a potential indicator of nonclass...
Creation of NOON states by double Fock-state/Bose-Einstein condensates
State of single particle state variable theory the measuring accuracy measuring phase the condensate
2014/12/19
NOON states (states of the form |N〉 a |0〉 b +|0〉 a |N〉 b where a and b are single particle states) have been used for predicting violations of hidden-variable theories (Greenbe...
Under so-called primitive ontology approaches, in fully describing the history of a quantum system, one thereby attributes interesting properties to regions of spacetime. Primitive ontology approaches...
