We observe seasonal seismic wave speed changes (dv/v) in the San Jacinto fault area and investigate several likely source mechanisms. Velocity variations are obtained from analysis of 6 yr data of vertical component seismic noise recorded by 10 surface and six borehole stations.We study the interrelation between dv/v records, frequency-dependent seismic noise properties, and nearby environmenta…

In this paper, two separate but related goals are tackled. The first one is to demonstrate that in some saturated rock textures the non-linear behaviour of induced polarization (IP) and the violation of Ohm’s law not only are real phenomena, but they can also be satisfactorily predicted by a suitable physical-mathematical model, which is our second goal. This model is based on Fick’s second…

For the purpose of clarifying a new approach to understanding quantum entanglement using thermofield dynamics (TFD), entanglement entropies of non-equilibrium finite-spin systems are examined for both traditional and extended cases. The extended entanglement entropy, ˆS, is derived, and it is found that the conditions for the maximum entangled state can be obtained through this approach. The …

Many salt diapirs are thought to have formed as a result of down-building, which implies that the top of the diapir remained close to the surface during syn-halokinetic sediment deposition. Down-building is largely a 3-D process and in order to better understand what controls the patterns of the diapirs that form by this process, we here perform 3-D numerical models of down-built diapirs initia…

An irreducible four-point vertex composed of the most-crossed diagrams involved in Bethe–Salpeter equation for an averaged two-photon propagator in a system of metal nanoparticles was calculated directly in coordinate representation without the traditional introduction of an EM-energy diffusion coefficient. These diagrams describe the interference of amplitudes corresponding to two possible …

If the tensor-to-scalar ratio r of cosmological perturbations takes a large value r ∼ 0.1, which may be inferred from the recent BICEP2 result, we can hope to determine thermal history, in particular, the reheating temperature, TR, after inflation by space-based laser interferometers. It is shown that upgraded and upshifted versions of DECIGO may be able to determine TR if it lies in the …

A geometrical method of formulating self-similar models in general relativity or in other gravitational theories is presented. The method consists of two techniques: (1) a Kaluza–Klein-like dimensional reduction technique for self-similar spacetimes, and (2) a systematic method of describing tensor fields on a self-similar spacetime in terms of fields on the reduced space. It is shown that th…

We describe a multihomogeneity theory for source-parameter estimation of potential fields. Similar to what happens for random source models, where the monofractal scaling-law has been generalized into a multifractal law, we propose to generalize the homogeneity law into a multihomogeneity law. This allows a theoretically correct approach to study real-world potential fields, which are inhomogen…

A spatially averaged mean-field model for fully or partially ordered members of the ilmenite–hematite solid solution series is rigorously derived from the Heisenberg Hamiltonian by first assuming no temporal correlation of atomic spins, and then by spatially averaging over spins at equivalent atomic positions. The model is based on the geometry of exchange interactions between nearest and ne…

We explore how the η–π0 mixing angle and the η meson decay into π+π− π0 and 3π0 are modified n the nuclear medium on the basis of the in-medium chiral effective theory with varying isospin asymmetry α, where α ≡ δρ/ρ with δρ = ρn − ρp and ρ = ρn + ρp. We find that the larger the …
