recommendations! Published in 2020 at "Classical and Quantum Gravity"

DOI: 10.1088/1361-6382/ab7288

Abstract: A brief discussion is made about the relevance of surface terms in the Lagrangian and Hamiltonian formulations of theories of gravity. These surface terms play an important role in the variation of the action integral.… read more here.

DOI: 10.1088/1361-6382/ad9c0c

Abstract: Local Lorentz invariance is an important foundation of General Relativity, and its high-precision testing can help to explore the unified theories. In this work, we focus on the local Lorentz violating effect in pure gravity… read more here.

DOI: 10.1103/physrevd.96.086023

Abstract: We show that local Lorentz covariance arises canonically as the group of transformations between local thermal states in the framework of Local Quantum Physics, given the following three postulates: (i) Local observable algebras are finite-dimensional.… read more here.

DOI: 10.1103/physrevlett.119.192504

Abstract: The nuclear matrix elements for the spin operator and the momentum quadrupole operator are important for the interpretation of precision atomic physics experiments that search for violations of local Lorentz and CPT symmetry and for… read more here.
