A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
Proposal for observing non-Abelian statistics of Majorana-Shockley fermions in an optical lattice
non-Abelian statistics Majorana-Shockley fermions an optical lattice
2016/1/22
Besides the conventional bosons and fermions, in synthetic two-dimensional (2D) materials there could exist more exotic quasiparticles with non-Abelian statistics, meaning that the quantum states in t...
Design of Geo-ontology Based on Concept Lattice
Geo-ontology Concept Ontology-property Semantic Relation
2015/12/2
Ontology is an explicit specification of a conceptualization in Artificial Intelligence. Geo-ontology is a very complex and intricate concept. Lots of researchers begin to research Geo-ontology, but m...
Linearly homomorphic signatures over binary fields and new tools for lattice-based signatures
binary fields lattice-based signatures
2015/8/5
Our scheme can be used to authenticate linear transformations of signed data, such as those arising when computing mean and least squares fit or in networks that use network coding. Our construction g...
Lattice basis delegation in fixed dimension and shorter ciphertext hierarchical IBE

2015/8/5
We present a technique for delegating a short lattice basis that has the advantage of keeping the lattice dimension unchanged upon delegation. Building on this result, we construct two new hierarchica...
We construct an efficient identity based encryption system based on the standard learning with errors (LWE) problem. Our security proof holds in the standard model. The key step in the construction is...
Symmetric quadrature rules for simplexes based on sphere close packed lattice arrangements
Quadrature Integration Symmetric Triangle

Lattice and Momentum Space Approach to Bound States and Excitonic Condensation via User Friendly Interfaces
exciton condensation Lattice
2015/1/19
In this thesis, we focus on two broad categories of problems, exciton condensation and bound states, and two complimentary approaches, real and momentum space, to solve these problems. In chapter 2 we...

2011/10/9
Abstract: We study random spatial permutations on Z^3 where each jump x -> \pi(x) is penalized by a factor exp(-T ||x-\pi(x)||^2). The system is known to exhibit a phase transition for low enough T wh...
