Interchain-Frustration-Induced Metallic State in Quasi-One-Dimensional Mott Insulators

The mechanism that drives a metal-insulator transition in an undoped quasi-one-dimensional Mott insulator is examined in the framework of the Hubbard model with two different hoppings t_⊥1 and t_⊥2 between nearest-neighbor chains. By applying an N_⊥-chain renormalization group method at the two-loop level, we show how a metallic state emerges when both t_⊥1 and t_⊥2 exceed critical values. In the metallic phase, the quasiparticle weight becomes finite and develops a strong momentum dependence. We discuss the temperature dependence of the resistivity and the impact of our theory in the understanding of recent experiments on half-filled molecular conductors.journal articl

A Method Of Estimation Of Elastic Properties And Thicknesses Of Soil Layers Using Vertical Harmonic Loading On Ground Surface And Its Numerical Verification

This paper presents a new method that may achieve a more accurate and lower cost estimation of elastic properties and thicknesses of soil deposits. The kernel of the proposed method, being independent of the usually adopted assumption that only one Rayleigh wave model is dominant, is to use the near field characteristics of all types of P-SV wave motions on the surface of elastic multi-layered half space generated by the vertical harmonic load applied on its surface. The near field wave motions are accurately simulated by the stiffness matrix method as one of more powerful numerical solutions, and then the following two physical quantities, which can be observable in the field, are used in inversion analysis: （1） the predominant frequency for which the dynamic vertical displacement on the soil surface takes a maximum value, and （2） the frequency variation of the phase velocity at a point on the soil surface near the vertical harmonic load. The phase velocity used in the proposed method is a local quantity varying with the location from the vertical load, because of using all types of waves and their modes. To demonstrate the capability and reliability of the proposed method, the numerical examples are presented by using regular and irregular soil profiles

Polarization Image Sensor for Highly Sensitive Polarization Modulation Imaging Based on Stacked Polarizers

In this article, We demonstrated an image sensor for detecting changes in polarization with high sensitivity. For this purpose, we constructed an optical system with a two-layer structure, comprising an external polarizer and polarizers on a pixel array. An external polarizer is used to enhance the polarization rotation while reducing the intensity to avoid pixel saturation of the image sensor. Using a two-layer structure, the two polarizers can be arranged under optimal conditions and the image sensor can achieve high polarization-change detection performance. We fabricated the polarization image sensor using a 0.35- μm CMOS process and, by averaging 50 ×50 pixels and 96 frames, achieved a polarization rotation detection limit of 5.2 ×10?4? at a wavelength of 625 nm. We also demonstrated the applicability of electric-field distribution imaging using an electrooptic crystal (ZnTe) for weak-polarization-change distribution measurements.journal articl
