description: We derive a kinetic equation for chiral matter at non-zero chemical potential that governs the response of the parity odd part of the distribution function to perturbations of the Robertson-Walker metric. The derivation is based on a recent evaluation of the gravitational polarization tensor at non-zero chemical potential. We also provide the equations for gravity waves that follow from the anisotropic stress tensor describing the lepton asymmetry. These equations can be used to assess the effects that a non-zero neutrino chemical potential would have on the evolution of cosmological perturbations.

Publisher: name: arXiv

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Cluster structures and monopole transitions in positive parity states of $^{16}$O were investigated based on the generator coordinate method calculation of an extended $^{12}$C+$α$ cluster model. The ground and excited states of a $^{12}$C cluster are taken into account by using $^{12}$C wave functions obtained with the method of antisymmetrized molecular dynamics. The $0^+_2$ state of $^{16}$O and its rotational members, the $2^+_1$ and $4^+_1$ states are described well by the cluster states dominated by the $^{12}$C($0^+_1$)+$α$ structure. Above the $^{12}$C($0^+_2$)+$α$ threshold energy, we obtained a $0^+$ state having the $^{12}$C($0^+_2$)+$α$ cluster structure, which is considered to be a candidate for the $4α$ cluster gas state. The band structures were discussed based on the calculated $E2$ transition strength. Isoscalar Monopole excitations from the ground state were also discussed.

description: A major discovery of Parker Solar Probe (PSP) was the presence of large numbers of localized increases in the radial solar wind speed and associated sharp deflections of the magnetic field - switchbacks (SB). A possible generation mechanism of SBs is through magnetic reconnection between open and closed magnetic flux near the solar surface, termed interchange reconnection that leads to the ejection of flux ropes (FR) into the solar wind. Observations also suggest that SBs undergo merging, consistent with a FR picture of these structures. The role of FRs merging in controlling the structure of SB in the solar wind is explored through direct observations, through analytic analysis, and numerical simulations. Analytic analysis reveals key features of the structure of FR and their scaling with the heliocentric distance R that are consistent with observations and that reveal the critical role of merging in controlling the SB structure. FR merging is shown to be energetically favorable to reduce the strength of the wrapping magnetic field and drive the observed elongation of SBs. A further consequence is the resulting dominance of the axial magnetic field within SBs that leads to the characteristic sharp rotation of the magnetic field into the axial direction at the SB boundary that is revealed in observations. Finally, the radial scaling of the SB area in the FR model of SBs suggests that the observational probability of SB identification should be insensitive to R, which is consistent with the most recent statistical analysis of SB observations from PSP.

description: We investigated the relationship between hot (~10 MK) and warm (~1 MK) plasma ejections observed in the solar corona during some flares from April 1998 to December 2001. Based on the catalog of X-ray Plasma Ejections (XPEs) observed by the Soft X-ray Telescope onboard the Yohkoh satellite, we have identified counterparts of XPEs in extreme-ultraviolet (EUV) images, derived by the TRACE satellite. We found that the XPEs are always associated with the EUV ejections. In most cases, ejections of warm plasma start earlier than ejections of hot plasma. The comprehensive analysis of kinematic and morphology evolution of the most interesting and well-observed events is also given

description: We present a numerical approach for computing attractive-repulsive power law equilibrium measures in arbitrary dimension. We prove new recurrence relationships for radial Jacobi polynomials on $d$-dimensional ball domains, providing a substantial generalization of the work based on recurrence relationships of Riesz potentials on arbitrary dimensional balls. Among the attractive features of the numerical method are good efficiency due to recursively generated banded and approximately banded Riesz potential operators and computational complexity independent of the dimension $d$, in stark contrast to the widely used particle swarm simulation approaches for these problems which scale catastrophically with the dimension. We present several numerical experiments to showcase the accuracy and applicability of the method and discuss how our method compares with alternative numerical approaches and conjectured analytical solutions which exist for certain special cases. Finally, we discuss how our method can be used to explore the analytically poorly understood gap formation boundary to spherical shell support.

description: An original experimental method for determining the empirical probability distribution function (PDF) of the quality factor (Q) of a mode-stirred reverberation chamber is presented. Spectral averaging of S-parameters across a relatively narrow frequency interval at a single pair of locations for the transmitting and receiving antennas is applied to estimate the stored and dissipated energy in the cavity, avoiding the need for spatial scanning to obtain spatial volume or surface averages. The effective number of simultaneously excited cavity modes per stir state, M, can be estimated by fitting the empirical distribution to the parametrized theoretical distribution. The measured results support a previously developed theoretical model for the PDF of Q and show that spectral averaging over a bandwidth as small as a few hundred kHz is sufficient to obtain accurate results.

description: We present our first results on a new sample containing all single G,K and M giants down to V = 4 mag in the Solar vicinity, suitable for spectropolarimetric (Stokes V) observations with Narval at TBL, France. For detection and measurement of the magnetic field (MF), the Least Squares Deconvolution (LSD) method was applied (Donati et al. 1997) that in the present case enables detection of large-scale MFs even weaker than the solar one (the typical precision of our longitudinal MF measurements is 0.1-0.2 G). The evolutionary status of the stars is determined on the basis of the evolutionary models with rotation (Lagarde et al. 2012; Charbonnel et al., in prep.) and fundamental parameters given by Massarotti et al. (1998). The stars appear to be in the mass range 1-4 M_sun, situated at different evolutionary stages after the Main Sequence (MS), up to the Asymptotic Giant Branch (AGB). The sample contains 45 stars. Up to now, 29 stars are observed (that is about 64 % of the sample), each observed at least twice. For 2 stars in the Hertzsprung gap, one is definitely Zeeman detected. Only 5 G and K giants, situated mainly at the base of the Red Giant Branch (RGB) and in the He-burning phase are detected. Surprisingly, a lot of stars ascending towards the RGB tip and in early AGB phase are detected (8 of 13 observed stars). For all Zeeman detected stars v sin i is redetermined and appears in the interval 2-3 km/s, but few giants with MF possess larger v sin i.

description: We introduce a new scheme to realize suspended, multi-terminal graphene structures that can be current annealed successfully to obtain uniform, very high quality devices. A key aspect is that the bulky metallic contacts are not connected directly to the part of graphene probed by transport measurements, but only through etched constriction, which prevents the contacts from acting invasively. The device high quality and uniformity is demonstrated by a reproducibly narrow (delta_n ~ 10^9 cm^-2) resistance peak around charge neutrality, by carrier mobility values exceeding 10^6 cm^2/V/s, by the observation of integer quantum Hall plateaus starting at 30 mT and of symmetry broken states at about 200 mT, and by the occurrence of a negative multi-terminal resistance directly proving the occurrence of ballistic transport. As these multi-terminal devices enable measurements that cannot be done in a simpler two-terminal configuration, we anticipate that their use in future studies of graphene-based systems will be particularly relevant.

China-Venezuela: When Economic Statecraft Creates Economic Power

description: This paper identifies a causal path between economic statecraft and economic power using Chinese economic statecraft in Venezuela as a case study. Chinese economic statecraft has become a unique phenomenon in the global economy. From investments in infrastructure projects to energy mining opportunities, foreign direct investments, and patient capital loans, Chinese economic statecraft differs from previous examples of statecraft. China has implemented its economic statecraft with the goal of achieving its strategic interests in overseas markets and expand its economy by gaining access to resources. This trend has resulted in the Chinese Belt and Road Initiative (BRI), a massive overseas economic investment project aimed to connect China with the rest of the world’s economies. While the conventional wisdom on Chinese economic statecraft would agree that China is expanding its economic power, the conventional wisdom lacks a clear path between economic statecraft and economic power. Additionally, the literature on Chinese economic statecraft seldom includes sufficient case studies analyzing the effects of economic statecraft in Latin America. This paper argues that there is a two-way path that clarifies when economic statecraft creates economic power. First, a state is said to achieve economic power when its economic statecraft capitalizes on material or power resources from a target state. Second, a state can achieve economic power over a target state when its economic statecraft includes economic coercion and economic inducements that result in a target state’s changing its behavior. Evidence of change in a target state’s behavior includes adoption, maintenance, refrainment, or abandonment. In the context of Chinese economic statecraft in Venezuela, China has been able to gain economic power by gaining access to valuable geostrategic resources such as oil and gold. Additionally, China has been able to gain economic power in Venezuela by using methods of 3 economic inducements and economic coercion that have influenced the Venezuelan government into adoption reforms to its economy.

description: The purpose of this article is twofold. First, we attempt to give a brief overview of the different application areas of quantum electrodynamics (QED). These include fundamental physics (prediction of atomic energy levels), where the atom may be exposed to additional external fields (hyperfine splitting and g factor). We also mention QED processes in highly intense laser fields, and more applied areas like Casimir and Casimir--Polder interactions. Both the unifying aspects as well as the differences in the the theoretical treatment required by these application areas (such as the treatment of infinities) are highlighted. Second, we discuss an application of the formalism in the fundamentally interesting area of the prediction of energy levels, namely, the hyperfine structure of P states of muonic hydrogen.

description: Every general relativity textbook emphasizes that coordinates have no physical meaning. Nevertheless, a coordinate choice must be made in order to carry out real calculations, and that choice can make the difference between a calculation that is simple and one that is a mess. We give a concrete illustration of the maxim that "coordinates matter" using the exact Schwarzschild solution for a vacuum, static, spherical spacetime. We review the standard textbook derivation, Schwarzschild's original 1916 derivation, and a derivation using the Landau-Lifshitz formulation of the Einstein field equations. The last derivation is much more complicated, has one aspect for which we have been unable to find a solution, and gives an explicit illustration of the fact that the Schwarzschild geometry can be described in infinitely many coordinate systems.

description: We present near-infrared spectroscopy and 1 mm line and continuum observations of a recently identified site of high mass star formation likely to be located in the Central Molecular Zone near Sgr C. Located on the outskirts of the massive evolved HII region associated with Sgr C, the area is characterized by an Extended Green Object measuring ~10" in size (0.4 pc), whose observational characteristics suggest the presence of an embedded massive protostar driving an outflow. Our data confirm that early-stage star formation is taking place on the periphery of the Sgr C HII region, with detections of two protostellar cores and several knots of H2 and Brackett gamma emission alongside a previously detected compact radio source. We calculate the cores' joint mass to be ~10^3 Msun, with column densities of 1-2 x 10^24 cm-2. We show the host molecular cloud to hold ~10^5 Msun of gas and dust with temperatures and column densities favourable for massive star formation to occur, however, there is no evidence of star formation outside of the EGO, indicating that the cloud is predominantly quiescent. Given its mass, density, and temperature, the cloud is comparable to other remarkable non-star-forming clouds such as G0.253 in the Eastern CMZ.

description: In divalent Eu systems, the 4f local moment has a pure spin state J=S=7/2. Although the absence of orbital moment precludes crystal electric field effects, we report a sizeable magnetic anisotropy in single crystals of EuRh2Si2. We observed a surprisingly complex magnetic behavior with three succesive phase transitions. The Eu2+ moments order in a likely amplitude-modulated structure below 24.5K, undergoing a further transition to a structure that is possibly of the equal moment type, and a first order transition at lower temperatures, presumably into a spin spiral structure. The sharp metamagnetic transition observed at low fields applied perpendicular to the hard axis is consistent with a change from a spiral to a fan structure. These magnetic structures are presumably formed by ferromagnetic planes perpendicular to the c axis, stacked antiferromagnetically along c but not of type I, at least just below the ordering temperature. Since EuRh2Si2 is isoelectronic to EuFe2As2, our results are also relevant for the complex Eu-magnetism observed there, especially for the transition from an antiferromagnetic to a ferromagnetic state observed in EuFe2P2 upon substituting As by P.

description: We present a combined Suzaku and Swift BAT broad-band E=0.6-200keV spectral analysis of three 3C 111 observations obtained in 2010. The data are well described with an absorbed power-law continuum and a weak (R~0.2) cold reflection component from distant material. We constrain the continuum cutoff at E_c~150-200keV, which is in accordance with X-ray Comptonization corona models and supports claims that the jet emission is only dominant at much higher energies. Fe XXVI Lyαemission and absorption lines are also present in the first and second observations, respectively. The modelling and interpretation of the emission line is complex and we explore three possibilities. If originating from ionized disc reflection, this should be emitted at r_in> 50r_g or, in the lamp-post configuration, the illuminating source should be at a height of h> 30r_g over the black hole. Alternatively, the line could be modeled with a hot collisionally ionized plasma with temperature kT = 22.0^{+6.1}_{-3.2} keV or a photo-ionized plasma with logξ=4.52^{+0.10}_{-0.16} erg s^{-1} cm and column density N_H > 3x10^23 cm^{-2}. However, the first and second scenarios are less favored on statistical and physical grounds, respectively. The blue-shifted absorption line in the second observation can be modelled as an ultra-fast outflow (UFO) with ionization parameter logξ=4.47^{+0.76}_{-0.04} erg s^{-1} cm, column density N_H=(5.3^{+1.8}_{-1.3})x 10^{22} cm^{-2} and outflow velocity v_out = 0.104+/-0.006 c. Interestingly, the parameters of the photo-ionized emission model remarkably match those of the absorbing UFO. We suggest an outburst scenario in which an accretion disc wind, initially lying out of the line of sight and observed in emission, then crosses our view to the source and it is observed in absorption as a mildly-relativistic UFO.

description: Reaction of thiopyrano[4,3-b]indole-3(5H)-thiones and dimethyl acetylenedicarboxylate (DMAD) proceeds via two competing cascade pathways. Initially, both the pathways begin from thiocarbonyl sulfur and acetylene carbon atoms interaction. Then two parallel processes take place: an alkyne–thiocarbonyl metathesis and a (3 + 2) cycloaddition. In the next stages, in both cases, thiophene ring formation and thiopyran ring opening proceed. Finally, (4 + 2) cycloaddition reactions of intermediate thioketones and a second equivalent of DMAD leads to the resulting thiopyrano[4,3-b]indole derivatives bearing thienyl substituent. The kinetic and thermodynamic characteristics of both pathways were compared on the basis of DFT and ab initio 6-311++G(d,p) quantum chemical calculations.

The behavior of magnetoresistance is found to be similar for all samples - it is negative in weak fields and becomes positive with increase of magnetic field. The result apparently contradicts to existing theories. To explain experimental data we suggest that clusters of overlapping quantum dots are formed. These clusters are assumed to have metal-like conductance, the charge transfer taking place via hopping between the clusters. Relatively strong magnetic field shrinks electron wave functions decreasing inter-cluster hopping and, therefore, leading to a positive magnetoresistance. Weak magnetic field acts on "metallic" clusters destroying interference of electron wave function corresponding to different paths (weak localization) inside clusters. The interference may be restricted either by inelastic processes, or by the cluster size. Taking into account WL inside clusters and hopping between them within the effective medium approximation we extract effective parameters characterizing charge (magneto) transport.

description: Coordination polymers (CPs) represent a potentially highly valuable class of materials for next-generation applications in heavy metal removal and as antibacterial agents. Ligands bearing sulfur donors are ideal candidates for the preparation of CPs for these applications since sulfur atom has lone pairs of electrons which could be donated to some metal ions, thereby binding the metals selectively; and it is also effective in disrupting bacterial functioning. Herein, we report, the synthesis of the crystal (1crys) and the powder (1powd) forms of the Zn(II)-based CP [Zn(TDPA)2(TMPy)2]n (1) (where TDPA = 3,3-thiodipropionic acid and TMPy = 4,4-trimethylenedipyridine) . Structural elucidation of the CPs – 1crys and 1powd were undertaken by means of FTIR, TGA and PXRD. The 1powd was obtained in much higher yields than the 1crys, and heavy metal removal behavior and antibacterial activity of the former were extensively investigated. Excellent removal capacities of 667 mg/g for Ag(I) and for Pb(II) by 1powd in single batch studies were observed. Additionally, 1powd inhibited the growth of six common bacterial strains and showed minimum inhibitory concentrations comparable to reported antibacterial agents. The efficiency of 1powd for these applications is linked to the sulfur-containing ligand used in the construction of the CP and its polymeric structure. Overall, the ease of preparation, yield, outstanding heavy metal removal capacities and potency in inhibiting bacterial growth offers 1powd as a highly adaptable and multifunctional material.

description: We present an analytical model for the theoretical analysis of spin dynamics and spontaneous symmetry breaking in a spinor Bose-Einstein condensate (BEC). This allows for an excellent intuitive understanding of the processes and provides good quantitative agreement with experimental results in Phys. Rev. Lett. 105, 135302 (2010). It is shown that the dynamics of a spinor BEC initially prepared in an unstable Zeeman state mF=0 (|0>) can be understood by approximating the effective trapping potential for the state |+-1> with a cylindrical box potential. The resonances in the creation efficiency of these atom pairs can be traced back to excitation modes of this confinement. The understanding of these excitation modes allows for a detailed characterization of the symmetry breaking mechanism, showing how a twofold spontaneous breaking of spatial and spin symmetry can occur. In addition a detailed account of the experimental methods for the preparation and analysis of spinor quantum gases is given.

description: A straightforward and convenient synthesis of symmetrical and unsymmetrical thiourea derivatives by the reaction of primary amines and carbon disulfide in the presence of a Zn catalyst is presented. Under modest reaction conditions, a range of biologically relevant thiourea derivatives can be produced in good to outstanding yields without a lengthy work-up. A variety of primary aliphatic and aromatic amines with various substituted functional groups were transformed into thiourea derivatives. Zn-mediated symmetric thiourea creation occurs at room temperature for aliphatic amines, whereas for aromatic amines it occurs at 60°C. However, unsymmetrical thiourea for aliphatic amines occurs at 0°C. Benefits of this method include environment-friendly reaction conditions, sustainability, and enumerating tolerance of functional groups such as hydroxyl and halides. Experimental observations were rationalized by DFT calculations based on transition structures and zwitterionic intermediate stabilities.

description: Cu (OAc)2 was immobilized on the surface of magnetic nanoparticles modified by Imine-Thiazole acting as a ligand. This immobilization is done to fabricate a new and green magnetically recoverable copper catalyst [Fe3O4@SiO2-(Imine-Thiazole)-Cu (OAc)2]. Techniques such as ICP-OES, TEM, FT-IR, EDX, SEM, TGA, VSM, and XRD were used to characterize the structure of Fe3O4@SiO2-(Imine-Thiazole)-Cu (OAc)2 nanocomposite. To Synthesize 2-substituted benzothiazoles, the nanocomposite of Fe3O4@SiO2-(Imine-Thiazole)-Cu (OAc)2 was used as a catalyst via a one-pot three-component reaction of 2-iodoanilines, benzyl chlorides and S8. Recycling experiments revealed that a simple magnetic separation could be used to recover the copper nanocatalyst, and this nanocatalyst can be recycled eight times without any deterioration in catalytic activity.

description: Accurate weather prediction is essential for many aspects of life, notably the early warning of extreme weather events such as rainstorms. Short-term predictions of these events rely on forecasts from numerical weather models, in which, despite much improvement in the past decades, outstanding issues remain concerning model uncertainties, and increasing demands for computation and storage resources. In recent years, the advance of deep learning offers a viable alternative approach. Here, we show that a 3D convolutional neural network using a single frame of meteorology fields as input is capable of predicting the precipitation spatial distribution. The network is developed based on 39-years (1980-2018) data of meteorology and daily precipitation over the contiguous United States. The results bring fundamental advancements in weather prediction. First, the trained network alone outperforms the state-of-the-art weather models in predicting daily total precipitation, and the superiority of the network extends to forecast leads up to 5 days. Second, combining the network predictions with the weather-model forecasts significantly improves the accuracy of model forecasts, especially for heavy-precipitation events. Third, the millisecond-scale inference time of the network facilitates large ensemble predictions for further accuracy improvement. These findings strongly support the use of deep-learning in short-term weather predictions.

description: The transition between different states in manganites can be driven by various external stimuli. Controlling these transitions with light opens the possibility to investigate the microscopic path through which they evolve. We performed femtosecond (fs) transmission electron microscopy on a bi-layered manganite to study its response to ultrafast photoexcitation. We show that a photoinduced temperature jump launches a pressure wave that provokes coherent oscillations of the lattice parameters, detected via ultrafast electron diffraction. Their impact on the electronic structure are monitored via ultrafast electron energy loss spectroscopy (EELS), revealing the dynamics of the different orbitals in response to specific structural distortions.

description: The rational assembly of monomers, in principle, enables the design of a specific periodicity of polymeric frameworks, leading to a tailored set of electronic structure properties in these solid-state materials. The further development of these emerging systems requires a combination of both experimental and theoretical studies. Here, we investigated the electronic structures of two-dimensional polymeric frameworks based on triazine and benzene rings, by means of electrochemical techniques. The experimental density of states was obtained from quasi-open-circuit voltage measurements through galvanostatic intermittent titration technique, which we show to be in excellent agreement with first principles calculations performed for two and three-dimensional structures of these polymeric frameworks. These findings suggest that the electronic properties do not only depend on the number of stacked layers but also on the ratio of the different aromatic rings.
