چکیده
We study the properties of pseudo entropy, a new generalization entanglement in free Maxwell field theory $d = 4$ dimension. prepare excited states by different components strengths located at Euclidean times acting on vacuum. compute difference between R\'{e}nyi entropy and ground state observe that changes significantly near boundary subsystems vanishes far away from boundary. Near subsystems, depends ratio two where operators are kept. To begin with, we develop method to evaluate conformal scalar $d=4$ with fixed weight vacuum only subsystems. also show suitable analytical continuation leads evaluation real-time evolution during quenches.

Entanglement entropy in SU(N) gauge theory
The entanglement entropy of SU(N) lattice gauge theory is studied exactly in 1 + 1 space-time dimensions and in Migdal-Kadanoff approximation in higher dimensional space. The existence of a non-analytical behavior reminiscent of a phase transition for a characteristic size of the entangled region is demonstrated for higher dimensional theories.
متن کاملPseudo-observables in Axial gauge
We have given a first application of the Axial gauge à la Dams and Kleiss to the Standard Model (SM) physics at the LHC. We have focused on the issue of providing a well-behaved signal definition in presence of potentially strong gauge cancellations at high energies. As a first illustration, we have analysed the production of WZ vector-boson pairs, which gives rise to four final-state fermions....
متن کاملBlack Hole Entropy from Non-Perturbative Gauge Theory
We present the details of a mean-field approximation scheme for the quantum mechanics of N D0-branes at finite temperature. The approximation can be applied at strong 't Hooft coupling. We find that the resulting entropy is in good agreement with the Bekenstein-Hawking entropy of a ten-dimensional non-extremal black hole with 0-brane charge. This result is in accord with the duality conjectured...
متن کاملLeaky Pseudo-Entropy Functions
Pseudo-random functions (PRFs) introduced by Goldwasser, Goldreich, and Micali (FOCS 1984), are one of the most important building blocks in cryptography. A PRF family is a family of seeded functions {fs}, with the property that no efficient adversary can tell the difference between getting oracle access to a random PRF function fs, and getting oracle access to a truly random function. In this ...
متن کاملEntanglement entropy in lattice gauge theories
We report on the recent progress in theoretical and numerical studies of entanglement entropy in lattice gauge theories. It is shown that the concept of quantum entanglement between gauge fields in two complementary regions of space can only be introduced if the Hilbert space of physical states is extended in a certain way. In the extended Hilbert space, the entanglement entropy can be partiall...
