Subjects: subject: 530 Physik

description: The drift-diffusion formalism for spin-polarized carrier transport in semiconductors is generalized to include spin-orbit coupling. The theory is applied to treat the extrinsic spin Hall effect using realistic boundary conditions. It is shown that carrier and spin-diffusion lengths are modified by the presence of spin-orbit coupling and that spin accumulation due to the extrinsic spin Hall effect is strongly and qualitatively influenced by boundary conditions. Analytical formulas for the spin-dependent carrier recombination rates and inhomogeneous spin densities and currents are presented.
Spin-wave excitations in epitaxial ultrathin FeCo with zero magnetocrystalline anisotropy

description: Spin-wave theory predicts reduced thermal spin-wave excitations due to a magnetic anisotropy. Recent results show that a strong uniaxial in-plane anisotropy in ultrathin Fe/GaAs(001) films indeed stabilizes the ferromagnetic order versus thermal spin excitations [Kipferl et al., J. Appl. Phys. 97, 10B313 (2005)]. In order to study whether a fourth-order in-plane anisotropy has a similar effect epitaxial Fe70Co30/Au(001) samples with zero magnetocrystalline anisotropy were studied and compared to results for Fe/Au(001). The temperature dependence of the spontaneous magnetization MS for T$\lt$0.5Tc can be well described by the Bloch [Z. Phys. 61, 206 (1930)] T3/2 law in the entire thickness range. However, for each thickness B is reduced in Fe70Co30/Au(001) compared to Fe/Au(001) films despite the reduced anisotropy. This means that the effect of a weak in-plane anisotropy is overcompensated by the enhanced exchange interaction.

description: Spintronics, or spin electronics, involves the study of active control and manipulation of spin degrees of freedom in solid-state systems. This article reviews the current status of this subject, including both recent advances and well-established results. The primary focus is on the basic physical principles underlying the generation of carrier spin polarization, spin dynamics, and spin-polarized transport in semiconductors and metals. Spin transport differs from charge transport in that spin is a nonconserved quantity in solids due to spin-orbit and hyperfine coupling. The authors discuss in detail spin decoherence mechanisms in metals and semiconductors. Various theories of spin injection and spin-polarized transport are applied to hybrid structures relevant to spin-based devices and fundamental studies of materials properties. Experimental work is reviewed with the emphasis on projected applications, in which external electric and magnetic fields and illumination by light will be used to control spin and charge dynamics to create new functionalities not feasible or ineffective with conventional electronics.
title: Energy transfer in the lower trophic pelagic food web of the Celtic Sea ecosystem
Creators: name: Patel, Roweena
Publisher: name: University of Reading
Year: 2023

description: This thesis provides new understanding on the trophic role of Small Pelagic Fish (SPF) within the 
Celtic Sea ecosystem. SPF facilitate energy transfer, and changes in their community assemblages 
could impact food web dynamics. Anchovy, sardine, herring, mackerel, horse mackerel, and sprat
spend some or all of their life within the Celtic Sea ecosystem and are of commercial and ecological 
importance. SPF are predominantly planktivorous, transferring energy from lower (e.g., plankton) to 
higher trophic levels (e.g., seabirds). The Celtic Sea is relatively understudied despite having 
undergone environmental changes within the last decades (e.g., recent increase in anchovy, and a 
decline in herring). The trophic interactions of SPF with planktonic communities and the surrounding 
environment of the Celtic Sea were investigated through i) diet analysis of SPF (stomach sampling 
campaign); ii) validation, and analysis of temporal/spatial variability of satellite retrieved 
phytoplankton chlorophyll-a; and iii) ecosystem modelling (Ecopath with Ecosim, EwE) to investigate
the effect of SPF dynamics on the wider Celtic Sea food web.
Stomach analyses indicated seasonal variation in SPF diet, although, calanoid copepods were 
consumed year-round. As these species are predominantly planktivorous, and chlorophyll-a is a 
proxy for phytoplankton biomass (a key input into ecosystem models), validation of satellite retrieved 
chlorophyll-a was undertaken for three algorithms, Sentinel-3A OLCI-OC4ME, Sentinel-3A OLCI-NN, and MODIS-Aqua-OCI+OC3, for the region. Satellite outputs were then considered for use in 
the Celtic Sea ecosystem model (EwE). Diet of SPF from this study and updated biomass for 2013-
2021 were used as an input. The EwE model of the Celtic Sea demonstrated potential to address 
management related questions regarding SPF. Through the improvement and evaluation of 
ecosystem model inputs (diet studies and satellite validation), and implementation into the current 
EwE model, this research has highlighted SPF are key in pelagic energy transfer in the Celtic Sea.
Orbital and spin relaxation in single and coupled quantum dots

Publisher: name: Universität Regensburg
Year: 2006
Subjects: subject: 530 Physik

description: Phonon-induced orbital and spin relaxation rates of single electron states in lateral single and double quantum dots are obtained numerically for realistic materials parameters. The rates are calculated as a function of magnetic field and interdot coupling, at various field and quantum dot orientations. It is found that orbital relaxation is due to deformation potential phonons at low magnetic fields, while piezoelectric phonons dominate the relaxation at high fields. Spin relaxation, which is dominated by piezoelectric phonons, in single quantum dots is highly anisotropic due to the interplay of the Bychkov-Rashba and Dresselhaus spin-orbit couplings. Orbital relaxation in double dots varies strongly with the interdot coupling due to the cyclotron effects on the tunneling energy. Spin relaxation in double dots has an additional anisotropy due to anisotropic spin hot spots which otherwise cause giant enhancement of the rate at useful magnetic fields and interdot couplings. Conditions for the absence of the spin hot spots in in-plane magnetic fields (easy passages) and perpendicular magnetic fields (weak passages) are formulated analytically for different growth directions of the underlying heterostructure. It is shown that easy passages disappear (spin hot spots reappear) if the double dot system loses symmetry by an xy-like perturbation.

Phosphaalkene monomers and their polymerization
Creators: name: Chen, Leixing
Publisher: name: University of British Columbia
Year: 2019

description: Living polymerization is a useful technique that is used to synthesize macromolecules with controlled architectures and tailor-made properties. Although this technique is widely used for the polymerization of organic monomers, the living polymerization of inorganic monomers is exceedingly rare. The prospect of synthesizing new inorganic-organic hybrid macromolecules with tailor-made structures is quite attractive due to the chemical functionality imparted by the inorganic moiety. Our group has developed the living anionic polymerization of Mes-P=CPh₂ to give chemically functional homo- and block-copolymers with phosphine moieties in the polymer backbone. Thus far, copolymers with styrene and isoprene have been prepared. In Chapter 2, the first poly(methylenephophine)-block-poly(methylmethacrylate) (PMP-b-PMMA) block copolymers will be reported. PMP-b-PMMA's with a variety of chain lengths have been synthesized and fully characterized by NMR spectroscopy, gel permeation chromatography (GPC) and matrix-assisted laser desorption-mass spectrometry (MALDI-MS). To fully understand the process of polymerization, the activation energy (Ea) was determined for the secBuLi-initiated polymerization of Mes-P=CPh₂ in nonpolar solvent toluene with TMEDA coordinator (Ea = 16.7 ± 0.7 kcal·mol-¹). In Chapter 3, a simple route to “masked” phosphaalkenes bearing P-Ar (Ar = aryl) and C-H substituents will be explored. The design of monomers bearing substituents smaller than Mesityl at phosphorus and phenyl at carbon, e.g. Mes-P=CPh2, poses considerable synthetic challenge. The present results will provide evidence that a masked phosphaalkene compound has been prepared as a transient species using a masked approach. The research included in this thesis extends the variety of phosphaalkene-based block copolymers that can be prepared. It also offers new perspectives in synthesis masked phosphaalkene compounds.
title: Leadership as practice: understanding the emergence of conscious coalescence through video ethnography
Creators: name: Robinson, Jennifer
Publisher: name: University of Reading
Year: 2021

description: Rather than impose a normative view of what leadership should look like, new emancipatory ideas using process and practice encourage researchers to consider what is happening when people come together to create leadership. I am generally interested in the activity and agency from which leadership emerges and I locate this interest in the literature of Leadership-as-Practice (LAP).
LAP considers that collaborative agency is inseparable from leadership. However collaborative agency relies on multiple individuals transcending their embeddedness, and yet this process is not well articulated, nor has it been studied in a manner that is congruent with the underpinning assumptions of LAP. In this thesis, my specific purpose is to uncover the processes by which individuals transcend their embeddedness, a process I call ‘Conscious Coalescence’. My guiding research questions are: What is the lived experience of participants when Conscious Coalescence emerges? And: How does Conscious Coalescence emerge (and not emerge) in groups of collaborative agents?
My research demonstrates that Conscious Coalescence is a vibrant state that people recognise even if they cannot name it. Participants reported “all pinging off each other” and moments that were “kinda magical”. These exuberant expressions leave me in little doubt that they felt a shift, like a gear change, signalling an unspoken understanding of ‘‘an I that is we and a we that is I’’ (Hegel, 1977, sec.177). This powerful existential shift is more possible and more prevalent than might be imagined.

It seems that Conscious Coalescence is not a once-in-a-meeting experience but might fleetingly arise and fade in micro segments.
As a qualitative study, my aim is theory elaboration, drawing on and extending important ideas from research on LAP. In total, I seek to put forward eight contributions to the field of LAP along with a further contribution to Method based on my novel research approach.

description: Motivated by recent interest in the Nernst effect in cuprate superconductors, we calculate this magneto-thermo-electric effect for an arbitrary (anisotropic) quasiparticle dispersion relation and elastic scattering rate. The exact solution of the linearized Boltzmann equation is compared with the commonly used relaxation-time approximation. We find qualitative deficiencies of this approximation, to the extent that it can get the sign wrong of the Nernst coefficient. Ziman's improvement of the relaxation-time approximation, which becomes exact when the Fermi surface is isotropic, also cannot capture the combined effects of anisotropy in dispersion and scattering.

description: We have investigated the electron spin resonance at nonzero wave vector in GaAs single quantum wells by combining the virtues of high frequency surface acoustic wave generation to produce excitations with large wave numbers with a sensitive optical scheme to detect resonant absorption. The observed large deviations from the single particle Zeeman energy are attributed to the exchange interaction. The enhancement of the electronic g* factor is, however, substantially smaller compared with theoretical predictions for spin waves when adopting a bare Coulomb interaction potential.
Helical Edge Modes near Transition to Topological Insulator with Indirect Gap
Creators: name: Mao, Shijun

Publisher: name: arXiv
Year: 2010
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Helical edge modes are characteristic of topological insulators in two dimensions. This paper demonstrates that helical edge modes remain across transitions to ordinary insulators or to semimetals under certain condition. Straight and zigzag edges are considered in a tight-binding model on square lattice. We focus on the case of indirect gap in bulk topological insulators, and obtain the spectrum of edge modes on both sides of transitions. For straight edge, the helical edge mode in topological insulators with strong particle-hole asymmetry has a reentrant region in momentum space. Edge modes show up even in ordinary insulators, but are absent in semimetals. In zigzag edge, the helical edge mode survives in both semimetals and ordinary insulators. However, the edge modes are absent inside the energy gap of ordinary insulators. All results are obtained analytically.

description: To understand quantum mechanical transport in a ferromagnetic semiconductor, the knowledge of basic material properties such as the phase coherence length and corresponding dephasing mechanism are indispensable ingredients. The lack of observable quantum phenomena has prevented experimental access to these quantities so far. Here we report the observations of universal conductance fluctuations in ferromagnetic (Ga,Mn)As. The analysis of the length and temperature dependence of the fluctuations reveals a T-1 dependence of the dephasing time.

Spin-orbit effects in single-electron states in coupled quantum dots
Creators: name: Stano, Peter
name: Fabian, Jaroslav
Publisher: name: Universität Regensburg
Year: 2005
Subjects: subject: 530 Physik

description: Spin-orbit effects in single electron states in laterally coupled quantum dots in the presence of a perpendicular magnetic field are studied by exact numerical diagonalization. Dresselhaus (linear and cubic) and Bychkov-Rashba spin-orbit couplings are included in a realistic model of confined dots based on GaAs. Group theoretical classification of quantum states with and without spin orbit coupling is provided. Spin-orbit effects on the g-factor are rather weak. It is shown that the frequency of coherent oscillations (tunneling amplitude) in coupled dots is largely unaffected by spin-orbit effects due to symmetry requirements. The leading contributions to the frequency involves the cubic term of the Dresselhaus coupling. Spin-orbit coupling in the presence of magnetic field leads to a spin-dependent tunneling amplitude, and thus to the possibility of spin to charge conversion, namely spatial separation of spin by coherent oscillations in a uniform magnetic field. It is also shown that spin hot spots exist in coupled GaAs dots already at moderate magnetic fields, and that spin hot spots at zero magnetic field are due to the cubic Dresselhaus term only.

Aharonov-Bohm oscillations investigated in the cotunneling regime demonstrate coherent tunneling through nonresonant states. Visibilities of more than 0.8 are measured indicating that phase-coherent processes are involved in the elastic and inelastic cotunneling. An oscillation-phase change of is detected as a function of bias voltage at the inelastic cotunneling onset.

It is found that the maximum Tc depends on the substituted element, so it is important to substitute various elements to explore new iron-based superconductors with higher Tc.

description: The notion of zitterbewegung is a long-standing prediction of relativistic quantum mechanics. Here we extend earlier theoretical studies on this phenomenon for the case of III–V zinc-blende semiconductors which exhibit particularly strong spin-orbit coupling. This property makes nanostructures made of these materials very favorable systems for possible experimental observations of zitterbewegung. Our investigations include electrons in n-doped quantum wells under the influence of both Rashba and Dresselhaus spin-orbit interactions, and also the two-dimensional hole gas. Moreover, we give a detailed anaysis of electron zitterbewegung in quantum wires which appear to be particularly suited for experimentally observing this effect.

description: The regional contribution to the geo-neutrino signal at Gran Sasso National Laboratory (LNGS) was determined based on a detailed geological, geochemical and geophysical study of the region. U and Th abundances of more than 50 samples representative of the main lithotypes belonging to the Mesozoic and Cenozoic sedimentary cover were analyzed. Sedimentary rocks were grouped into four main "Reservoirs" based on similar paleogeographic conditions and mineralogy. Basement rocks do not outcrop in the area. Thus U and Th in the Upper and Lower Crust of Valsugana and Ivrea-Verbano areas were analyzed. Based on geological and geophysical properties, relative abundances of the various reservoirs were calculated and used to obtain the weighted U and Th abundances for each of the three geological layers (Sedimentary Cover, Upper and Lower Crust). Using the available seismic profile as well as the stratigraphic records from a number of exploration wells, a 3D modelling was developed over an area of 2^{\circ}x2^{\circ} down to the Moho depth, for a total volume of about 1.2x10^6 km^3. This model allowed us to determine the volume of the various geological layers and eventually integrate the Th and U contents of the whole crust beneath LNGS. On this base the local contribution to the geo-neutrino flux (S) was calculated and added to the contribution given by the rest of the world, yielding a Refined Reference Model prediction for the geo-neutrino signal in the Borexino detector at LNGS: S(U) = (28.7 \pm 3.9) TNU and S(Th) = (7.5 \pm 1.0) TNU. An excess over the total flux of about 4 TNU was previously obtained by Mantovani et al. (2004) who calculated, based on general worldwide assumptions, a signal of 40.5 TNU. The considerable thickness of the sedimentary rocks, almost predominantly represented by U- and Th- poor carbonatic rocks in the area near LNGS, is responsible for this difference.

title: The laser-as-detector approach exploiting mid-infrared emitting interband cascade lasers: A potential for spectroscopy and communication applications
Creators: name: Herdt, Andreas
Publisher: name: UNSPECIFIED
Year: 2020

description: Interband cascade lasers are exceptionally versatile, high-tech semiconductor lasers. They represent the latest generation of semiconductor lasers that generate radiation in the mid-infrared wavelength domain and are therefore preferred as coherent light sources in spectroscopy and free-space-communication setups. In this thesis they are used to evaluate the so-called laser-as-detector approach. The laser-as-detector approach is a well-known but little used technique that allows dispensing external optical detection units. A semiconductor laser itself is used as a detector, even though it is operating as usual. The principle is based on the fact that external optical perturbation change the charge carrier density in the interband-cascade-laser and manifest themselves accordingly in changes of the terminal voltage. Using the laser-as-detector approach, two spectroscopic methane sensors are then set up and their detection limits are evaluated. The laser-as-detector approach is then used to build a free-space-communication communication device without any detector.

The Hummingbird Creek archaeological site : an ancient hunting camp in Alberta’s central Rockies, Canada.
Creators: name: Allan, Timothy E.
Publisher: name: University of British Columbia
Year: 2018

description: This thesis focuses on the significance of the Hummingbird Creek site (FaPx-1), a pre-contact archaeological site occupied between ~2,500 to 1,000 years ago, in the Alberta Rocky Mountains. This site yielded approximately 1,400 stone artifacts, including throwing spear (atlatl) projectile points, hide scrapers, expedient knives and production debris. I use geochemical (Portable X-Ray Fluorescence, pXRF) and mineralogical (Raman Spectroscopy) analytical methods on artifacts and source samples. I compared samples from local rock, and material gathered from a nearby procurement area, Pineneedle Creek, with artifacts found at FaPx-1. Carbonate diagenesis, and silica (SiO2) content were key attributes of artifacts, and we successfully associated some artifacts from FaPx-1 with Pineneedle Creek material. I infer that the local rock around FaPx-1 was virtually ignored, perhaps because of very low silica content. Based on expectations made through ethnographic examples of other montane hunter-gatherers, the material culture from FaPx-1 likely represents a specialized hunting camp; intended for staging hunting expeditions to areas known to yield successful hunts. Local Stoney First Nation traditional place names and oral accounts corroborate the interpretations of archaeological data and emphasize the need for Indigenous perspectives in Rocky Mountain archaeology in Alberta. This thesis incorporates material culture and geological analysis with a land-use and traditional knowledge interpretation and emphasizes the need for Indigenous perspectives in archaeological research.
A Real Time Optimistic Strategy to achieve Concurrency Control in Mobile Environments Using On-demand Multicasting

Publisher: name: arXiv
Year: 2010
Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)

description: In mobile database environments, multiple users may access similar data items irrespective of their physical location leading to concurrent access anomalies. As disconnections and mobility are the common characteristics in mobile environment, performing concurrent access to a particular data item leads to inconsistency. Most of the approaches use locking mechanisms to achieve concurrency control. However this leads to increase in blocking and abort rate. In this paper an optimistic concurrency control strategy using on-demand multicasting is proposed for mobile database environments which guarantees consistency and introduces application-specific conflict detection and resolution strategies. The simulation results specify increase in system throughput by reducing the transaction abort rates as compared to the other optimistic strategies proposed in literature.

Role of excited states for the material gain and threshold current density in quantum wire intersubband laser structures
Creators: name: Herrle, Thomas

Publisher: name: Universität Regensburg
Year: 2006
Subjects: subject: 530 Physik

description: We calculated the material gain and the threshold current density for quantum wire intersubband laser structures. In quantum cascade laser devices with active regions of lower dimensionality a reduction of the non-radiative losses and consequently an increase in the material gain and a reduction of the threshold current density is predicted. In our calculations of the material gain and the threshold current density for a realistic quantum wire intersubband laser structure fabricated by the cleaved edge overgrowth (CEO) technique, however, it turns out that excited states formed in those structures even reduce the material gain compared to conventional quantum well cascade lasers. The threshold current density also turns out to be increased due to the reduced material gain on the one hand and due to a small optical confinement factor in such structures on the other hand. The main consequence for the design of such quantum wire laser structures is to avoid the formation of excited states to be able to benefit from the reduction of the dimensionality of the electron system in terms of reduced non- radiative losses.
Corrosion behavior of B206 aluminum-copper casting alloy in seawater environment : electrochemical and microstructural studies
Creators: name: Pournazari, Shabnam
Publisher: name: University of British Columbia
Year: 2018

description: Aluminum-copper casting alloys have relatively high strength and hardness, fatigue and creep resistances and good machinability, all of each are dependent on the copper content of the alloy. The Al-Cu casting alloy (4.2-5.0 wt% Cu), known as B206, is a potential candidate material for use in marine applications where good mechanical properties and high strength to weight ratio is desired. These properties are ideal for components of tidal-based energy generating systems. However, corrosion continues to be an issue. This dissertation presents and discusses the results of several electrochemical and microstructural investigations conducted on B206, contributing to a further understanding of the fundamental corrosion processes. Applications of this research are strongest within the marine industry field, yet are extendable to other infrastructural and engineering applications such as aerospace and military. Results of this work elucidate the mechanism of localized corrosion of B206 alloy in seawater. Focused ion beam (FIB) used to determine the subsurface microstructure at local attack sites within the corroded area reveals that localized corrosion is propagated where continuous particles are buried beneath the surface. Propagating away from the initiation sites, corrosion develops preferentially along the grain boundary network beneath the alloy surface. Retrogression and re-aging (RRA) of the alloy to modify the grain structure and render uniform the distribution of the second phase is revealed not to have a substantial effect on the corrosion susceptibility of the alloy. However, Electrochemical Impedance Spectroscopy (EIS) and Mott-Schottky tests support the feasibility of implementing anodizing and possibly anodic protection systems for B206 in specific service environments. EIS was also used to determine the effect of cathodic protection (CP) on coated B206 and reveals that its corrosion resistance with CP is superior to the situation without CP and, therefore, that the coating is compatible with CP. Due to its use in the as-cast state, the effect of casting porosity on the corrosion of B206 was investigated using a pencil electrode method. Results reveal that the corrosion can be attributed to the local chemistry inside the pores (conductivity and potential at the bottom of pores).

description: Three-dimensional studies of convection in deep spherical shells have been used to test the hypothesis that the strong jet streams on Jupiter, Saturn, Uranus, and Neptune result from convection throughout the molecular envelopes. Due to computational limitations, these simulations must adopt viscosities and heat fluxes many orders of magnitude larger than the planetary values. Several numerical investigations have identified trends for how the mean jet speed varies with heat flux and viscosity, but no previous theories have been advanced to explain these trends. Here, we show using simple arguments that if convective release of potential energy pumps the jets and viscosity damps them, the mean jet speeds split into two regimes. When the convection is weakly nonlinear, the equilibrated jet speeds should scale approximately with F/nu, where F is the convective heat flux and nu is the viscosity. When the convection is strongly nonlinear, the jet speeds are faster and should scale approximately as (F/nu)^{1/2}. We demonstrate how this regime shift can naturally result from a shift in the behavior of the jet-pumping efficiency with heat flux and viscosity. Moreover, the simulations hint at a third regime where, at sufficiently small viscosities, the jet speed becomes independent of the viscosity. We show based on mixing-length estimates that if such a regime exists, mean jet speeds should scale as heat flux to the 1/4 power. Our scalings provide a good match to the mean jet speeds obtained in previous Boussinesq and anelastic, three-dimensional simulations of convection within giant planets over a broad range of parameters. When extrapolated to the real heat fluxes, these scalings suggest that the mass-weighted jet speeds in the molecular envelopes of the giant planets are much weaker--by an order of magnitude or more--than the speeds measured at cloud level.

description: The blue light photoreceptor cryptochrome 3 (cry3) from Arabidopsis thaliana was characterized at room temperature in vitro in aqueous solution by optical absorption and emission spectroscopic studies. The protein non-covalently binds the chromophores flavin adenine dinucleotide (FAD) and N5,N10-methenyl-5,6,7,8-tetrahydrofolate (MTHF). In the dark-adapted state of cry3, the bound FAD is present in the oxidized form (FADox, ca. 38.5%), in the semiquinone form (FADH, ca. 5%), and in the fully reduced neutral form (FADredH2) or fully reduced anionic form (FADredH−, ca. 55%). Some amount of FAD (ca. 1.5%) in the oxidized state remains unbound probably caused by chromophore release and/or denaturation. Förster-type energy transfer from MTHF to FADox is observed. Photo-excitation reversibly modifies the protein conformation causing a slight rise of the MTHF absorption strength and an increase of the MTHF fluorescence efficiency (efficient protein conformation photo-cycle). Additionally there occurs reversible reduction of bound FADox to FADredH2 (or FADredH−, FADox photo-cycle of moderate efficiency), reversible reduction of FADH to FADredH2 (or FADredH−, FADH photo-cycle of high efficiency), and modification of re-oxidable FADredH2 (or FADredH−) to permanent FADredH2 (or FADredH−) with low quantum efficiency. Photo-excitation of MTHF causes the reversible formation of a MTHF species (MTHF′, MTHF photo-cycle, moderate quantum efficiency) with slow recovery to the initial dark state, and also the formation of an irreversible photoproduct (MTHF″).

description: The generation, manipulation and detection of spin-polarized electrons in low-dimensional semiconductors are at the heart of spintronics. Pure spin currents, that is, fluxes of magnetization without charge current, are quite attractive in this respect. A paradigmatic example is the spin Hall effect, where an electrical current drives a transverse spin current and causes a non-equilibrium spin accumulation observed near the sample boundary1, 2. Here we provide evidence for an another effect causing spin currents which is fundamentally different from the spin Hall effect. In contrast to the spin Hall effect, it does not require an electric current to flow: without bias the spin separation is achieved by spin-dependent scattering of electrons in media with suitable symmetry. We show, by free-carrier absorption of terahertz (THz) radiation, that spin currents flow in a wide range of temperatures. Moreover, the experimental results provide evidence that simple electron gas heating by any means is already sufficient to yield spin separation due to spin-dependent energy-relaxation processes.
Geometric View of Measurement Errors

description: The slope of the best fit line from minimizing the sum of the squared oblique errors is the root of a polynomial of degree four. This geometric view of measurement errors is used to give insight into the performance of various slope estimators for the measurement error model including an adjusted fourth moment estimator introduced by Gillard and Iles (2005) to remove the jump discontinuity in the estimator of Copas (1972). The polynomial of degree four is associated with a minimun deviation estimator. A simulation study compares these estimators showing improvement in bias and mean squared error.
