Correlation functions of harmonic lattices in d-dimensional space
Masafumi Shimojo, Satoshi Ishihara, Hironobu Kataoka +2
We study the correlation functions between the dynamical variables and between their conjugate momenta at sites of a harmonic lattice in the -dimensional Euclidean space. We sho…

Corner functions from entanglement indices of harmonic lattices
Masafumi Shimojo, Satoshi Ishihara, Hironobu Kataoka +1
We study the entanglement indices such as logarithmic negativities (LNs) and mutual informations (MIs) between two adjacent subsets in a isolated universal set of harmonic osci…
