Topological triply-degenerate point with double Fermi arcs
Yihao Yang, Hong-xiang Sun, Jian-ping Xia +6
Unconventional chiral particles have recently been predicted to appear in certain three dimensional (3D) crystal structures containing three- or more-fold linear band degeneracy po…
Quantum from principles without assuming definite causal structure
Ding Jia
There has been a body of works deriving the complex Hilbert space structure of quantum theory from axioms/principles/postulates to deepen our understanding about quantum theory and…
Reduction of correlations by quantum indefinite causal structure
Ding Jia
We show that quantum indefinite causal structure generically reduce two-party correlations. For significant indefiniteness in the causal structure captured by some general conditio…
Quantum field theory with indefinite causal structure
Ding Jia
Quantum field theory (QFT) in classical spacetime has revealed interesting and puzzling aspects about gravitational systems, in particular black hole thermodynamics and its informa…
Analogue of Null Geodesic in Quantum Spacetime
Ding Jia
In classical spacetime null geodesics give information on where free massless particles travel. In quantum spacetime where quantum indefiniteness renders spacetime fuzzy null geode…
Quantifying Causality in Quantum and General Models
Ding Jia
In studies of entanglement, finding out if a state is entangled and quantifying the amount of entanglement contained in a state are related but different questions. Similarly in st…
