We propose an experimental scheme to observe spin Hall effects with cold atoms in a light-induced gauge potential. Under an appropriate configuration, the cold atoms moving in a spatially varying laser field experience an effective spin-dependent gauge potential. Through numerical simulation, we demonstrate that such a gauge field leads to observable spin Hall currents under realistic condition...

This work studies the effects of an aluminum covering on the performance of cross-like Hall devices. Four different Hall sensor structures of various sizes were designed and fabricated. The sensitivity and offset of the Hall sensors, two key points impacting their performance, were characterized using a self-built measurement system. The work analyzes the influences of the aluminum covering on ...

Submitted for the MAR06 Meeting of The American Physical Society Strong correlation effects in the IR Hall Effect in the cuprates: an overview1 H.D. DREW, University of Maryland — The Hall Effect at infrared frequencies provides a sensitive probe of strong interaction effects in strongly correlated metals. Experimental results show that the strong interaction effects inter the Hall conductivity...

This paper has examined the analytical solution of steady fully developed natural convective flow of a viscous incompressible and electrically conducting fluid between vertical channel by taking the Hall current and induced magnetic field into account. We have obtained the non-dimensional simultaneous ordinary differential equations using the suitable non-dimensional variables and parameters in...

We show that electric field can induce spin polarization and dichroism effects in angle resolved photoemission spectroscopy ARPES in spin orbit coupling systems. The physical origin behind the effects essentially is the same as the intrinsic spin Hall effect induced by the electric field. Since the ARPES experiments have both energy and momentum resolutions, the origin of the intrinsic spin Hal...

Empirical results through a fixed effects regression model show that government size has a negative effect on growth mainly through hampering capital accumulation. When a sample is divided into OECD and non-OECD countries, the negative effect of government size on capital accumulation persists for non-OECD countries but not for OECD countries.

In this paper we present the current state of our research on simulation of temporal bone surgical procedures. We describe the results of tests performed on a virtual surgical training system for middle ear surgery. The work is aimed to demonstrate how expert surgeons and trainees can effectively use the system for training and assessment purposes. Preliminary kinematic and dynamic analysis of ...

Many studies find a strong negative association between crime and education. This raises the question whether crime reduces investment in human capital or whether education reduces criminal activity. This article investigates posed question by using fixed-effect estimation on data of Australian twins. We find early arrests (before the age of 18) both to have a strong effect on human capital acc...

Based on a model of human capital accumulation, we study convergence in academic achievement of native-born and immigrant students. The model captures the idea that human capital accumulation is a dynamic process depending on cognitive achievement accumulated at previous stages of a student’s academic life. This theoretical formalization provides a framework for the empirical analysis of dynami...
