description: States in the $N=28$ nucleus $^{46}$Ar have been studied by a two-neutron transfer reaction at REX-ISOLDE (CERN). A beam of radioactive $^{44}$ at an energy of 2.16~AMeV and a tritium loaded titanium target were used to populate $^{46}$ by the t($^{44}$,p) two-neutron transfer reaction. Protons emitted from the target were identified in the T-REX silicon detector array. The excitation energies of states in $^{46}$ have been reconstructed from the measured angles and energies of recoil protons. Angular distributions for three final states were measured and based on the shape of the differential cross section an excited state at 3695~keV has been identified as $J^π= 0^+$. The angular differential cross section for the population of different states are compared to calculations using a reaction model employing both sequential and direct transfer of two neutrons. Results are compared to shell model calculations using state-of-the-art effective interactions.

description: We report epitaxial synthesis of superconducting CsxWO3 (x = 0.11, 0.20, 0.31) films on Y-stabilized ZrO2 (111) substrates. The hexagonal crystal structure was verified not only for composition within the stable region of bulk (x = 0.20, 0.31), but also for the out-of-range composition (x = 0.11). The onset of superconducting transition temperature (TC) was recorded 5.8 K for x = 0.11. We found strong correlation between TC and c-axis length, irrespective of the Cs content. The results indicate that hidden superconducting phase region of hexagonal tungsten bronze is accessible by using epitaxial synthesis of lightly doped films.

description: A prototype of the double-heterostructure hot-carrier solar cell was built by the cost effective and
upscalable processes such as electrodeposition and magnetron sputtering. Device under test is based on
InP/PbSe/ZnO:Al thin film structure. Chemical composition of the deposited PbSe films was checked by energy
dispersive X-ray spectrometry (EDX). Structure analysis of the substrates and films was carried out by electron
backscatter diffraction (EBSD). Band alignment at InP/PbSe and PbSe/ZnO heterojunctions was estimated by X-ray
photoelectron spectroscopy (XPS). The full double-heterojunction structure was tested with respect to the ability to
extract hot carriers from absorber by exposure to the laser beam radiation at selected wavelengths. Functionality of
the proposed material combination is in agreement with reconstructed from XPS band structure at InP/PbSe and
PbSe/ZnO interfaces.

description: In this paper an approach for decreasing the computational effort required for the split-step Fourier method (SSFM) is introduced. It is shown that using the sparsity property of the simulated signals, the compressive sampling algorithm can be used as a very efficient tool for the split-step spectral simulations of various phenomena which can be modeled by using differential equations. The proposed method depends on the idea of using a smaller number of spectral components compared to the classical split-step Fourier method with a high number of components. After performing the time integration with a smaller number of spectral components and using the compressive sampling technique with l1 minimization, it is shown that the sparse signal can be reconstructed with a significantly better efficiency compared to the classical split-step Fourier method. Proposed method can be named as compressive split-step Fourier method (CSSFM). For testing of the proposed method the Nonlinear Schrodinger Equation and its one-soliton and two-soliton solutions are considered.

description: The recent advances in machine learning algorithms have boosted the application of these techniques to the field of condensed matter physics, in order e.g. to classify the phases of matter at equilibrium or to predict the real-time dynamics of a large class of physical models. Typically in these works, a machine learning algorithm is trained and tested on data coming from the same physical model. Here we demonstrate that unsupervised and supervised machine learning techniques are able to predict phases of a non-exactly solvable model when trained on data of a solvable model. In particular, we employ a training set made by single-particle correlation functions of a non-interacting quantum wire and by using principal component analysis, k-means clustering, and convolutional neural networks we reconstruct the phase diagram of an interacting superconductor. We show that both the principal component analysis and the convolutional neural networks trained on the data of the non-interacting model can identify the topological phases of the interacting model with a high degree of accuracy. Our findings indicate that non-trivial phases of matter emerging from the presence of interactions can be identified by means of unsupervised and supervised techniques applied to data of non-interacting systems.

description: In this study, the photovoltaic performance improving of crystalline silicon (C-Si) solar cells
depending on the locations of photoluminescence (PL) emission of Eu-doped phosphor species and
the optical reflectance of the layer-structure of Eu-doped phosphor coating on an anti-reflective TiO2
layer is demonstrated. The surface morphologies and optical properties of the Eu-doped phosphor
species of 3-5 wt% mixed with Silicafilm (SiO2) coated on C-Si substrates using spin-on film
technique are characterized by scanning electron microscopy (SEM), PL, and optical reflectance
measurements. Furthermore, for C-Si solar cells with an anti-reflective TiO2 layer, the photovoltaic
performance of the cells depending on the location of PL emission of Eu-doped phosphor and the
optical reflectance of the combination of Eu-doped phosphor and anti-reflective TiO2 layer-structure
was examined using external quantum efficiency (EQE) response and photovoltaic current-voltage
(I-V) measurement under one sun AM 1.5G illumination at 25. The obtained EQE and photovoltaic
I-V results indicate that locations of PL emission of Eu-doped phosphor near the low reflective band
of the Eu-doped phosphor and anti-reflective TiO2 layer-structure can provide impressive
photovoltaic performance improvement.

description: We study the K-armed dueling bandit problem which is a variation of the classical Multi-Armed Bandit (MAB) problem in which the learner receives only relative feedback about the selected pairs of arms. We propose a new algorithm called Relative Exponential-weight algorithm for Exploration and Exploitation (REX3) to handle the adversarial utility-based formulation of this problem. This algorithm is a non-trivial extension of the Exponential-weight algorithm for Exploration and Exploitation (EXP3) algorithm. We prove a finite time expected regret upper bound of order O(sqrt(K ln(K)T)) for this algorithm and a general lower bound of order omega(sqrt(KT)). At the end, we provide experimental results using real data from information retrieval applications.

Our results reveal the necessity of constraining line depth and width concurrently with line energy to conclusively determine hotspot emission and corresponding magnetic field geometry. We then present the results of our simulations using effective area and response of various current and upcoming X-ray telescopes for magnetar spectral line detection and expand on the exciting opportunities upcoming telescopes provide to probe quiescent and burst emission region geometry and propagation in the extreme magnetic field of a magnetar

On ultra high energy cosmic rays and their resultant gamma rays

description: The Fermi Large Area Telescope (Fermi LAT) collaboration has recently reported on 50 months of measurements of the isotropic Extragalactic Gamma Ray Background (EGRB) spectrum between $100\mbox{MeV}$ and $820\mbox{GeV}$. Ultrahigh Energy Cosmic Ray (UHECR) protons interact with the Cosmic Microwave Background (CMB) photons and produce cascade photons of energies $10\mbox{MeV}\mbox{-}1\mbox{TeV}$ that contribute to the EGRB flux. We examine seven possible evolution models for UHECRs and find that UHECR sources that evolve as the Star Formation Rate (SFR), medium low luminosity active galactic nuclei type-1 ($L = 10^{43.5}\mbox{erg sec}^{-1}$ in the $[0.5\mbox{-}2]\mbox{KeV}$ band), and BL Lacertae objects (BL Lacs) are the most acceptable given the constraints imposed by the observed EGRB. Other possibilities produce too much secondary $γ$-radiation. In all cases, the decaying dark matter contribution improves the fit at high energy, but the contribution of still unresolved blazars, which would leave the smallest role for decaying dark matter, may yet provide an alternative improvement. The possibility that the entire EGRB can be fitted with resolvable but not-yet-resolved blazars, as recently claimed by Ajello et al. (2015), would leave little room in the EGRB to accommodate $γ$-rays from extragalactic UHECR production, even for many source evolution rates that would otherwise be acceptable. We find that, under the assumption of UHECRs being mostly protons, there is not enough room for producing extragalactic UHECRs with AGN, GRB, or even SFR source evolution. Sources that evolve as BL Lacs on the other hand, would produce much less secondary $γ$-radiation and would remain a viable source of UHECRs, provided that they dominate.

description: A quantum wire-on-well (WoW) structure, taking advantage of the layer undulation of an In-
GaAs/GaAs/GaAsP superlattice grown on a vicinal substrate, was demonstrated to enhance the carrier collection
from the confinement levels and extend the carrier lifetime (220 ns) by approximately 4 times as compared with a
planar reference superlattice. Strained InGaAs/GaAs/GaAsP superlattices were grown on GaAs substrates under exactly
the same condition except for the substrate misorientation (0o- and 6o- off). The growth on a 6o-off substrate induced
significant layer undulation as a result of step bunching and non-uniform precursor incorporation between
steps and terraces whereas the growth on a substrate without miscut resulted in planar layers. The undulation was the
most significant for InGaAs layers, forming periodically aligned InGaAs nanowires on planar wells, a wire-on-well
structure. As for the photocurrent corresponding to the sub-bandgap range of GaAs, the light absorption by the WoW
was extended to longer wavelengths and weakened as compared with the planar superlattice, and almost the same
photocurrent was obtained for both the WoW and the planar superlattice. Open-circuit voltage for the WoW was not
affected by the longer-wavelength absorption edge and the same value was obtained for the two structures. Furthermore,
the superior carrier collection in the WoW, especially under forward biases, improved fill factor compared with
the planer superlattice.

description: Multi-Quantum Well (MQW) solar cells are devices intended for use as single junction or within
multijunction cells, and presenting interestingly large open-circuit voltages. However, due to their particular band
structure, complex transport properties are involved. In this contribution, the influence of the host pin material (either
GaAs or InGaP) is investigated. For the InGaP case, extremely high open-circuit voltages are observed, larger than
what could be expected from a detailed balance argument. We explain this behavior by reduced hole transport
properties under forward voltage, so that the MQW contribution to the recombination is reduced. Nevertheless, as
seen on the external quantum efficiency, the MQW are active at short circuit, allowing increased current by
absorption below the bandgap of the host material.

description: Compressed sensing (CS) sampling theory is applied to the Light Beam Induced Current (LBIC)
measurement technique in order to significantly reduce measurement time while maintaining or increasing accuracy.
Using this method, a current map of the device can be reconstructed from far fewer measurements by means of an
optimisation algorithm. Measurement simulations are implemented using a two dimensional photovoltaic (PV) device
model to explore the capabilities and limitations of the method. A physical realisation of the technique is demonstrated.
The raster scanning process of the LBIC system is replaced with a Digital Micro-mirror Device (DMD) pattern
projection system. Measurement speed is also improved due to the response time of the DMD pattern generator, which
is less than 20μs. An experimental CS-LBIC setup, alongside with initial experimental results that indicate the
feasibility of the method are presented.

description: Among the four features unique to hot-carrier solar cells (HC-SCs): (i) carrier thermalization time and
(ii) carrier equilibration time in the absorber, (iii) energy-selection width, and (iv) conductance of the energyselective
contacts (ESCs), the requisites of (i)-(iii) have been clarified. To find the required values of (iv), we have
improved the detailed balance model of HC-SC operation to involve a finite value of the ESC conductance. We have
also derived a formulation to calculate the conductance of resonant tunneling diodes (RTDs) consisting of
semiconductor quantum dots (QDs) and quantum wells (QWs) based on the rigorous solutions of the effective-mass
Hamiltonians, and found that the requisite of (iv) can be, in principle, fulfilled using the QD- and QW-RTDs.

description: Thermophotovoltaic (TPV) technologies used in conjunction with present infrastructure can lead to
increased energy output by reclaiming the heat lost during production processes. To maximize the efficiency of these
sources, the conversion efficiency of the TPV system needs to be optimized. Metamaterials provide an excellent
medium for the creation of selective emitters. Such emitters tailor the incident light spectrum to the band gap of the
diode in question, offering the potential to reduce diode heating and increase efficiency. We have created such devices
at a wide range of wavelengths to observe the performance of various sized nanostructures at high temperatures. Usage
of conducting metals such as platinum and iridium makes the emitters able to withstand the high temperatures required
to create ideal spectra for III-V cells. Simulations from CST Microwave Studio were used in the design process and
testing of the emitters included ellipsometer absorption measurements and emission testing using a high temperature
blackbody source.
On the Characteristics of Footpoints of Solar Magnetic Flux Ropes during the Eruption

description: We investigate the footpoints of four erupted magnetic flux ropes (MFRs) that appear as sigmoidal hot channels prior to the eruptions in the Atmospheric Imaging Assembly high temperaure passbands. The simultaneous Helioseismic and Magnetic Imager observations disclose that one footpoint of the MFRs originates in the penumbra or penumbra edge with a stronger magnetic field, while the other in the moss region with a weaker magnetic field. The significant deviation of the axis of the MFRs from the main polarity inversion lines and associated filaments suggests that the MFRs have ascended to a high altitude, thus being distinguishable from the source sigmoidal ARs. The more interesting thing is that, with the eruption of the MFRs, the average inclination angle and direct current at the footpoints with stronger magnetic field tend to decrease, which is suggestive of a straightening and untwisting of the magnetic field in the MFR legs. Moreover, the associated flare ribbons also display an interesting evolution. They initially appear as sporadical brightenings at the two footpoints of and in the regions below the MFRs and then quickly extend to two slender sheared J-shaped ribbons with the two hooks corresponding to the two ends of the MFRs. Finally, the straight parts of the two ribbons separate from each other, evolving into two widened parallel ones. These features mostly conforms to and supports the recently proposed three-dimensional standard CME/flare model, i.e., the twisted MFR eruption stretches and leads to the reconnection of the overlying field that transits from a strong to weak shear with the increasing height.

description: The ultrafast heterogeneous electron transfer at the interface between the N719 ruthenium dye complex
and TiO2 is studied by means of ultrafast XUV photoemission spectroscopy. After optical excitation of the system by
a laser pulse of 530nm wavelength, XUV light obtained from high-order harmonic generation is utilized to probe the
electron density distribution of the involved ground and excited states at the interface. By using a spectral
decomposition of the transient emission signal we identified for the first time directly the absolute binding energies of
the dye singlet and triplet metal-to-ligand charge-transfer states. The advantage of studying simultaneously injection
kinetics and the electronic band alignment will be discussed and an outlook for future applications of this method in
view of other promising energy related materials will be presented.

description: We study the qualitative behavior of a model to represent local regulation in a metabolic network. The model is based on the end-product control structure introduced in [A. Goelzer, F. Bekkal Brikci, I. Martin-Verstraete et al., BMC Syst Biol 2 (2008), pp. 1--18]. In this class of regulation, the metabolite effector is the end-product of a metabolic pathway. We suppose the input to the pathway to switch between zero and a positive value according to the concentration of the metabolite effector. Considering the switched system as a differential inclusion, we prove that it converges to a globally uniformly asymptotically stable equilibrium point, reaches the sliding mode or oscillates around the sliding mode depending on the positive value of the input. Finally, we show that in any case the solution of the switched system is the limit of solutions of equation sequences with smooth or piecewise linear inputs.

description: Some asteroids contain water ice, and a space mission landing on an asteroid may take liquid to the surface of the asteroid. Gas pressure is very weak on the surface of asteroids. Here we consider the capillary action in a crack on the surface of irregular asteroids. The crack is modelled as a capillary which has a fixed radius. An asteroid s irregular gravitational potential influences the height of the liquid in the capillary. The height of the liquid in the capillary on the surface of such asteroids is derived from the asteroid s irregular gravitational potential. Capillary mechanisms are expected to produce an inhomogeneaous distribution of emergent liquid on the surface. This result is applied to asteroid 433 Eros, which has an irregular, elongated, and concave shape. Two cases are considered 1) we calculate the height of the liquid in the capillary when the direction of the capillary is perpendicular to the local surface of the asteroid; 2) we calculate the height of the liquid in the capillary when the direction of the capillary is parallel to the vector from the center of mass to the surface position. The projected height in the capillary on the local surface of the asteroid seems to depend on the assumed direction of the capillary.

description: Camera-based measurements, such as electroluminescence (EL), photoluminescence (PL), and infrared
(IR) technologies, offer excellent possibilities for determining production failures or defects in solar modules which
cannot be detected by means of standard power measurements. These types of optical measurement provide high
resolution images with a two-dimensional distribution of the characteristic features of thin film modules. This paper
focuses on quality control and characterization using PL and EL imaging with conventional cameras and an alternative
excitation source for the PL-setup.

description: The key to reducing photovoltaic costs is continual improvement in energy conversion efficiency. The
most successful approach to increasing this efficiency is to split sunlight into spectral bands and use a dedicated solar
cell to convert each band efficiently. Recently, we demonstrated sunlight to electricity conversion with confirmed
efficiency above the 40% landmark for the first time, using a 287-cm2 aperture area sub-module, notably by
innovative use of commercial III-V and silicon concentrator solar cells. This device was a prototype for a large
photovoltaic power tower, where sunlight is reflected from a field of sun-tracking heliostats to a dense photovoltaic
array mounted on a central tower. In this paper, we describe the outcomes from work directed at demonstrating
further sunlight conversion efficiency improvements, both by extending the above approach and by applying
similarly innovative ideas to one-sun modules, with >30% minimodule efficiency recently demonstrated.

description: Young and massive star clusters above a critical mass form thermally unstable clumps reducing locally the temperature and pressure of the hot 10$^{7}$~K cluster wind. The matter reinserted by stars, and mass loaded in interactions with pristine gas and from evaporating circumstellar disks, accumulate on clumps that are ionized with photons produced by massive stars. We discuss if they may become self-shielded when they reach the central part of the cluster, or even before it, during their free fall to the cluster center. Here we explore the importance of heating efficiency of stellar winds.

description: Perovskite/crystalline silicon tandem solar cells are one of the most promising approaches to reach
conversion efficiencies beyond 30% at reasonable costs. In the present paper, we present our research directions and
recent results. This includes fundamental studies on the perovskite material properties such as sub-band gap
absorption and complex refractive index, as well as the development of a broadband transparent rear electrode. The
electrode development enabled the fabrication of semitransparent perovskite cells with efficiencies up to 14.7%,
which then translates to four-terminal tandem measurements with total stabilized efficiency of up to 22.8%.
Furthermore, we present first results on monolithic perovskite/silicon tandems with total current of 32.25 mA/cm2 on
a flat wafer and finally provide optimization guidelines with optical simulations.
Bosonic integer quantum Hall states in topological bands with Chern number two

description: We study the interacting bosons in topological Hofstadter bands with Chern number two. Using exact diagonalization, we demonstrate that bosonic integer quantum Hall (BIQH) state emerges at integer boson filling factor $ν=1$ of the lowest Chern band with evidences including a robust spectrum gap and quantized topological Hall conductance two. Moreover, the robustness of BIQH state against different interactions and next-nearest neighbor hopping is investigated. The strong nearest neighbor interaction would favor a charge density wave. When the onsite interaction decreases, BIQH state undergoes a continuous transition into a superfluid state. Without next-nearest neighbor hopping, the ground state is possibly in a metallic Fermi-liquid-like phase.

On Strengthening of the Solar f-mode Prior to Active Region Emergence Using the Fourier-Hankel Analysis

description: Recent results of Singh et al. (2016) show that the emergence of an active region (AR) can be seen in a strengthening of the f-mode power up to two days prior of the region's formation. In the original work, ring diagram analysis was used to estimate the power evolution. In this study, we make use of the Fourier-Hankel method, essentially testing the aforementioned results with an independent method. The data is acquired from SDO/HMI, studying the ARs 11158, 11072, 11105, 11130, 11242 and 11768. Investigating the total power as a function of time, we find a similar behavior to the original work, which is an enhancement of f-mode power about one to three days prior to AR emergence. Analysis of the absorption coefficient $α$, yielded by a Fourier-Hankel analysis, shows neither absorption ($α> 0$) nor emission ($α< 0$) of power during the enhancement. Finding no changes of the absorption coefficient (i.e. $α= 0$) is an important result, as it narrows down the possible physical interpretation of the original f-mode power enhancement, showing that no directional dependence (in the sense of inward and outward moving waves) is present.

description: Two-dimensional carrier distribution in a phosphorus (P)-implanted emitter is observed by scanning
capacitance microscopy (SCM). The SCM image shows a clear contrast at an almost constant depth along the surface
of a silicon wafer with a pyramidal texture. Segregation of carriers in convex and concave regions of the pyramidal
texture was not observed. A non-monotonic SCM depth profile is discussed based on the applied bias and carrier
concentration. Junction depth of top, valley, and side wall of pyramidal texture is evaluated from SCM depth profile.
The junction depth of the side wall is nearly equal to that of the valley. Since the vertical junction depth immediately
beneath the surface of the texture is determined by diffusion from the side wall, it is longer than those of the side wall
and valley. Based on the SCM images, formation processes of p-n junction in a P-implanted emitter are discussed.

description: The interplay between superconductivity and charge density waves (CDWs) under hole doping in cuprates is one of the central phenomena in condensed matter physics. Recently, CDWs are also observed in CaCuO$_2$-analogous nickelates RNiO$_2$ (R = La, Nd) but exhibit fundamentally different hole-doping-dependent behaviors compared to that in cuprates, raising a challenging question on its origin. In this article, we propose that electronic instability (EI) and moment-dependent electron-phonon coupling (MEPC), mainly contributed by Ni 3dx2-y2 and R 5dz2, respectively, may be the possible reasons for CDW formation in RNiO$_2$. Without hole doping, a strong Fermi surface nesting (FSN) induced by the unique feature of van Hove singularity (VHS) across Fermi level exists in RNiO$_2$ but not in CaCuO$_2$, and the unusual temperature-insensitive feature of EI and MEPC could result in rather high temperature CDWs in RNiO$_2$. Under hole doping, the reduced FSN of Ni 3dx2-y2 by the shift of VHS and decreased occupation of R 5dz2 largely weaken EI and MEPC in RNiO$_2$, respectively, suppressing the CDW formation. Our theory not only offers possible explanations to some puzzling experimental observations, but also establishes a unified understanding on the hole-doping-dependent EI and MEPC in nickelates and cuprates.

description: Global energy demand has grown steadily since the industrial revolution. During the two decades from 1991 to 2012, total
primary energy demand (TPED) grew from 91,200 to 155,400 TWhth, or by 70%, and projections expect this number to increase
by a further 40% by 2040. Although greenhouse gas emissions in the energy sector have to be reduced to zero by mid-century
or earlier to avoid an ecologic disaster, less than 15% of this energy demand is supplied by renewable resources nowadays. The
International Energy Agency (IEA) has a significant impact on both political and economic decisions of governments and
stakeholders regarding energy. The World Energy Outlook (WEO) report published annually by the IEA projects for the
decades to come how TPED and electricity generation, amongst others, will evolve for all major technologies. Since the WEO
is often used as a basis for policy making on renewable and conventional energy, a comprehensive analysis of past WEO
projections is crucial. Such analysis will ensure well-grounded and realistic energy policy making and can contribute to efforts
to fight climate change and to achieve energy security.
In this article, the deviation between the real figures documented in the latest WEO reports and the projections of earlier ones
is analysed, as well as the different projections of all reports from 1994 to 2014. The results obtained so far show that projections
for solar technologies and wind energy have been strongly underestimated, whereas projections for nuclear energy are
contradictory from one year to the next. A key reason for the high deviations of solar PV and wind capacities in the projections
and the historic data is an incorrectly applied growth pattern. The WEO reports assume linear growth, whereas history shows
an exponential growth for the new renewable energy (RE) technologies. The current exponential growth is part of long-term
logistic growth of new RE technologies. Furthermore, a model proposed regarding RE technologies shows that to satisfy the
world’s needs with sustainable technologies in the decades to come, the approach of the WEO reports needs to be substantially
reworked.
Due to continuously falling prices of renewable energy technology, one can expect a fast deployment of renewables and a
replacement of conventional energy. In its latest projections the WEOs did not take into account recent developments, including
measures on climate protection and divestment of finance from the conventional energy sector. Therefore, policy-makers are
advised to consider the expansion of renewables well beyond the WEO projections in their energy policies in order to avoid
stranded investments in future
