Ultraviolet regularity from quantum gravitational indefinite causal structure

Ding Jia

Indefinite causal structure is generically present in theories of quantum gravity admitting a path integral formulation. We show that summing over causal structures eliminates ultr…

Causally neutral quantum physics

Ding Jia

In fundamental theories that accounts for quantum gravitational effects, the spacetime causal structure is expected to be quantum uncertain. Previous studies of quantum causal stru…

Causal order as a resource for quantum communication

Ding Jia, Fabio Costa

In theories of communication, it is usually presumed that the involved parties perform actions in a fixed causal order. However, practical and fundamental reasons can induce uncert…

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…

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…
