On Energy Functions for String-Like Continuous Curves, Discrete Chains, and Space-Filling One Dimensional Structures
Shuangwei Hu, Ying Jiang, Antti J. Niemi
The theory of string-like continuous curves and discrete chains have numerous important physical applications. Here we develop a general geometrical approach, to systematically der…
Remarks on effective action and entanglement entropy of Maxwell field in generic gauge
Sergey N. Solodukhin
We analyze the dependence of the effective action and the entanglement entropy in the Maxwell theory on the gauge fixing parameter in dimensions. For a generic value of …
Associative algebraic approach to logarithmic CFT in the bulk: the continuum limit of the gl(1|1) periodic spin chain, Howe duality and the interchiral algebra
A. M. Gainutdinov, N. Read, H. Saleur
We develop in this paper the principles of an associative algebraic approach to bulk logarithmic conformal field theories (LCFTs). We concentrate on the closed spin-chain…
Exact self-accelerating cosmologies in the ghost-free massive gravity -- the detailed derivation
Mikhail S. Volkov
We present the detailed derivation of the recently announced most general cosmological solution with homogeneous and isotropic metric in the ghost-free massive gravity theory. We u…
Notes on the ambient approach to boundary values of AdS gauge fields
Xavier Bekaert, Maxim Grigoriev
The ambient space of dimension d+2 allows to formulate both fields on AdS(d+1) and conformal fields in d dimensions such that the symmetry algebra o(d,2) is realized linearly. We e…
Newton-Hooke type symmetry of anisotropic oscillators
P. M. Zhang, P. A. Horvathy, K. Andrzejewski +2
The rotation-less Newton--Hooke - type symmetry found recently in the Hill problem and instrumental for explaining the center-of-mass decomposition is generalized to an arbitrary a…
