Exact calculation of entanglement negativity for a 1+1D massless scalar field using phase space methods
Jason Pye, Atharva Hingane, Robert H. Jonsson
Quantum fields exhibit a rich entanglement structure which is still not fully understood. In this work, we study the entanglement structure of the vacuum state of a massless scalar…
The negativity core of a 1+1D massless scalar quantum field
Jason Pye, Atharva Hingane, Robert H. Jonsson
Vacuum entanglement is a fundamental feature of quantum field theory exhibiting rich structure that is not completely understood. Here, we provide a complete characterization of th…
Lorentz-covariant sampling theory for fields
Jason Pye
Sampling theory is a discipline in communications engineering involved with the exact reconstruction of continuous signals from discrete sets of sample points. From a physics persp…
Covariant bandlimitation from Generalized Uncertainty Principles
Jason Pye
It is widely believed that combining the uncertainty principle with gravity will lead to an effective minimum length scale. A particular challenge is to specify this scale in a coo…
