Universal Entanglement Spectra of Gapped One-dimensional Field Theories

description: We discuss the entanglement spectrum of the ground state of a gapped (1+1)-dimensional system in a phase near a quantum phase transition. In particular, in proximity to a quantum phase transition described by a conformal field theory (CFT), the system is represented by a gapped Lorentz invariant field theory in the "scaling limit" (correlation length $ξ$ much larger than microscopic 'lattice' scale $a$), and can be thought of as a CFT perturbed by a relevant perturbation. We show that for such (1+1) gapped Lorentz invariant field theories in infinite space, the low-lying entanglement spectrum obtained by tracing out, say, left half-infinite space, is precisely equal to the physical spectrum of the unperturbed gapless, i.e. conformal field theory defined on a finite interval of length $L_ξ=$ $\log(ξ/a)$ with certain boundary conditions. In particular, the low-lying entanglement spectrum of the gapped theory is the finite-size spectrum of a boundary conformal field theory, and is always discrete and universal. Each relevant perturbation, and thus each gapped phase in proximity to the quantum phase transition, maps into a particular boundary condition. A similar property has been known to hold for Baxter's Corner Transfer Matrices in a very special class of fine-tuned, namely integrable off-critical lattice models, for the entire entanglement spectrum and independent of the scaling limit. In contrast, our result applies to completely general gapped Lorentz invariant theories in the scaling limit, without the requirement of integrability, for the low-lying entanglement spectrum. - The finite-size spectra of the entanglement Hamiltonian and of the physical Hamiltonian on an interval of length R exhibit entirely different behaviors upon crossover from the critical regime $R \ll ξ$ to the gapped regime $R \gg ξ$.

description: Lateral balancing currents are an immanent feature of solar cells with an inhomogeneous distribution of
photocurrent Iph(x,y) and/or diode current j01(x,y) leading to additional power losses and thus to a significant increase
of difficulty to analyze local efficiencies of solar cells. Due to fundamental physical restrictions like charge
conservation and having a potential distribution across a 2D grid network, astonishingly only the histogram information
(no local information!) of images of recombination strength and series resistance is needed to calculate all relevant
average information. This is completely analogous to the technique of frequency analysis used for code breaking used
for more than 1000 years where just a histogram analysis allows to identify the meaning and the position of all (most)
characters within a text. In this contribution, the theory and quantitative results for several inhomogeneous solar cells
with different kinds of lateral balancing currents are presented.

description: Recently, GRB 170817A was confirmed to be associated with GW 170817, which was produced by a neutron star - neutron star merger. It indicates that at least some short gamma-ray bursts come from binary neutron star mergers. Theoretically, it is widely accepted that short gamma-ray bursts can be produced by two distinctly different mechanisms, binary neutron star mergers and neutron star - black hole mergers. These two kinds of bursts should be different observationally due to their different trigger mechanisms. Motivated by this idea, we collect a universal data set constituted of 51 short gamma-ray bursts observed by $Swift$/BAT, among which 14 events have extended emission component. We study the observational features of these 51 events statistically. It is found that our samples are consisted of two distinct groups. They clearly show a bimodal distribution when their peak photon fluxes at 15-150 keV band are plotted against the corresponding fluences. Most interestingly, all the 14 short bursts with extended emission lie in a particular region. When the fluences are plotted against the burst durations, short bursts with extended emission again tend to concentrate in the long duration segment. These features strongly indicate that short gamma-ray bursts really may come from two distinct types of progenitors. We argue that those short gamma-ray bursts with extended emission come from the coalescence of neutron stars, while the short gamma-ray bursts without extended emission come from neutron star - black hole mergers.

description: The magnetic chemically peculiar (CP2) stars of the upper main sequence are well-suited for investigating the impact of magnetic fields on the surface layers of stars, which leads to abundance inhomogeneities (spots) resulting in photometric variability. The light changes are explained in terms of the oblique rotator model; the derived photometric periods thus correlate with the rotational periods of the stars. CP2 stars exhibiting this kind of variability are classified as alpha2 Canum Venaticorum (ACV) variables. We have analysed around 3 850 000 individual photometric WASP measurements of magnetic chemically peculiar (CP2) stars and candidates selected from the Catalogue of Ap, HgMn, and Am stars, with the ultimate goal of detecting new ACV variables. In total, we found 80 variables, from which 74 are reported here for the first time. The data allowed us to establish variability for 23 stars which had been reported as probably constant in the literature before. Light curve parameters were obtained for all stars by a least-squares fit with the fundamental sine wave and its first harmonic. Because of the scarcity of Stroemgren uvbybeta measurements and the lack of parallax measurements with an accuracy better than 20%, we are not able to give reliable astrophysical parameters for the investigated objects.

description: We present the line-of-sight (LOS) velocities for 13 distant main sequence Milky Way halo stars with published proper motions. The proper motions were measured using long baseline (5-7 years) multi-epoch HST/ACS photometry, and the LOS velocities were extracted from deep (5-6 hour integrations) Keck II/DEIMOS spectra. We estimate the parameters of the velocity ellipsoid of the stellar halo using a Markov chain Monte Carlo ensembler sampler method. The velocity second moments in the directions of the Galactic $(l,b,$ LOS) coordinate system are $\langle v^2_l \rangle^{1/2} = 138^{+43}_{-26}$ km/s, $\langle v^2_b \rangle^{1/2} = 88^{+28}_{-17}$ km/s, and $\langle v^2_{\rm{LOS}} \rangle^{1/2} = 91^{+27}_{-14}$ km/s. We use these ellipsoid parameters to constrain the velocity anisotropy of the stellar halo. Ours is the first measurement of the anisotropy parameter $β$ using 3D kinematics outside of the solar neighborhood. We find $β=-0.3^{+0.4}_{-0.9}$, consistent with isotropy and lower than solar neighborhood $β$ measurements by 2$σ$ ($β_{SN} \sim 0.5-0.7$). We identify two stars in our sample that are likely members of the known TriAnd substructure, and excluding these objects from our sample increases our estimate of the anisotropy to $β=0.1^{+0.4}_{-1.0}$, which is still lower than solar neighborhood measurements by $1σ$. The potential decrease in $β$ with Galactocentric radius is inconsistent with theoretical predictions, though consistent with recent observational studies, and may indicate the presence of large, shell-type structure (or structures) at $r \sim 25$ kpc. The methods described in this paper will be applied to a much larger sample of stars with 3D kinematics observed through the ongoing HALO7D program.

description: We report on discrepancies between PC1d and Silvaco Atlas numerical device simulators detected in
simulations of performance parameters (efficiency, , open-circuit voltage, VOC, short-circuit current, JSC, and fill factor,
FF) vs. thickness, W, of light-trapping n-p Si solar cells. We treat such discrepancies as errors by taking the
Silvaco-values of parameters as references. The errors on  are particularly noticeable because they include the errors
on the remaining parameters, the most influencing of which are the errors on JSC and FF. The errors on JSC are due to
the different functions for absorption coefficient vs. wavelength in intrinsic Si used in the two simulations. The errors
on FF are due to the different dependences of ideality factor, n, on W. A function for n(W) fitting accurately the
n(W)-data of Silvaco-simulations is given. The Silvaco n(W)-dependence is imposed on PC1d-simulations and the errors
on  are reduced to minimum.

description: Two recent publications have reported intriguing analyses, tentatively suggesting that some aspects of IceCube data might be manifestations of quantum-gravity-modified laws of propagation for neutrinos. We here propose a strategy of data analysis which has the advantage of being applicable to several alternative possibilities for the laws of propagation of neutrinos in a quantum spacetime. In all scenarios here of interest one should find a correlation between the energy of an observed neutrino and the difference between the time of observation of that neutrino and the trigger time of a GRB. We select accordingly some GRB-neutrino candidates among IceCube events, and our data analysis finds a rather strong such correlation. This sort of studies naturally lends itself to the introduction of a "false alarm probability", which for our analysis we estimate conservatively to be of 1%. We therefore argue that our findings should motivate a vigorous program of investigation following the strategy here advocated.
description: In V2 the possible helicity dependence of the effects (only mentioned in a footnote of V1) is discussed in the main text, and we give an estimate of possible values the parameters could take in order to produce the feature found in the data

description: In this paper, we present a study on the impact of finger interruptions on PV solar cell performance. In order to model the influence of finger interruptions, we adopt a simulation tool, which is based on a distributed electrical network. The validation of the tool is verified by means of a comparison with experimental data. Distributed SPICE simulations are then carried out in order to investigate how the position and the dimension of the interruptions affect the main figures of merit of a solar cell. We also perform a statistical analysis in which interruptions are randomly generated along the solar cell.

description: The large level limit of the N=2 minimal models that appear in the duality with the N=2 supersymmetric higher spin theory on AdS_3 is shown to be a natural subsector of a certain symmetric orbifold theory. We study the relevant decompositions in both the untwisted and the twisted sector, and analyse the structure of the higher spin representations in the twisted sector in some detail. These results should help to identify the string background of which the higher spin theory is expected to describe the leading Regge trajectory in the tensionless limit.

description: In the crystalline silicon solar cell manufacturing wet etching process are widely used with a large usage of
acid and DI water and with a limited capability of reflectivity reduction. In this work, we replace wet etching by plasma
dry etching on 4 main processes. A new dry etch of saw damage coupled with front dry texturing and rear dry polishing
provides the possibility to replace wet bench by new dry etching equipment. Batch processing drastically reduces the
cost per wafer and increases the through put. Marathon test on 2000 multicrystalline wafers show a 0.2% absolute
increase of efficiency compare to wet acidic etching. Compatibility with diamond wire sawn wafers is evaluated and at
module level single cell mini module demonstrated no loss of performance on dry textured cells. In the last part, a dry
plasma emitter rear emitter etch is developed. A fine adjustment of process parameters provides a gain in isolation and in
Jsc corresponding to a 0.08% absolute efficiency gain.

description: Recently, a new form of light and temperature induced degradation (LeTID) has been discovered,
which does neither show the typical signs of the boron-oxygen-pair activation nor of the separation of iron-boron
complexes. In this work, multi crystalline cells of the passivated emitter and rear type (PERC) that show this form of
degradation are investigated. The impact of LeTID on cell parameters is investigated and spatially resolved
measurements are performed. This examination shows that the effect appears on the entire cell, while the grain
boundaries are less affected. Additionally the changes in the emitter, bulk, and rear recombination are investigated.
First, a slight degradation of the rear recombination occurs. It is followed by a strong decline of the bulk lifetime.
This indicates that light and elevated temperature degradation is related to a gradual change of the cell starting from
the back side. Finally, these LeTID-sensitive solar cells are compared to a second batch that was subject to a process
making the cells LeTID-resistant. It is shown that on these LeTID-resistant cells illumination does not cause a
significant loss of efficiency. Thus an optimized cell process can prevent this type of degradation.

description: The boron-oxygen related defect is a well-known lifetime killer and in consequence seemed to be a
show-stopper for the high efficiency solar cell development on boron-doped substrates. However, the related
degradation may be overcome by the regeneration process eliminating the harmful defects. The recently finished
research project BORNEO aimed at a more fundamental understanding of boron-oxygen related regeneration in order
to answer the pending questions that impede industrial application so far. Some basic relations between macroscopic
parameters (such as the manufacturing process of the solar cell and the regeneration conditions) and microscopic
processes (such as the defect kinetics) are explained, and which lessons were learned to be able to realize a fast and
reliable regeneration process not only on lifetime samples, but also on solar cell level, and why the chosen cell
architecture matters.
Numerical analysis of a mechanotransduction dynamical model reveals homoclinic bifurcations of extracellular matrix mediated oscillations of the mesenchymal stem cell fate

description: We perform one and two-parameter numerical bifurcation analysis of a mechanotransduction model approximating the dynamics of mesenchymal stem cell differentiation into neurons, adipocytes, myocytes and osteoblasts. For our analysis, we use as bifurcation parameters the stiffness of the extracellular matrix and parameters linked with the positive feedback mechanisms that up-regulate the production of the YAP/TAZ transcriptional regulators (TRs) and the cell adhesion area. Our analysis reveals a rich nonlinear behaviour of the cell differentiation including regimes of hysteresis and multistability, stable oscillations of the effective adhesion area, the YAP/TAZ TRs and the PPAR$γ$ receptors associated with the adipogenic fate, as well as homoclinic bifurcations that interrupt relatively high-amplitude oscillations abruptly. The two-parameter bifurcation analysis of the Andronov-Hopf points that give birth to the oscillating patterns predicts their existence for soft extracellular substrates ($<1kPa$), a regime that favours the neurogenic and the adipogenic cell fate. Furthermore, in these regimes, the analysis reveals the presence of homoclinic bifurcations that result in the sudden loss of the stable oscillations of the cell-substrate adhesion towards weaker adhesion and high expression levels of the gene encoding Tubulin beta-3 chain, thus favouring the phase transition from the adipogenic to the neurogenic fate.

description: Repeated injection of spin polarized carriers in a quantum dot leads to the polarization of nuclear spins, a process known as dynamic nuclear spin polarization (DNP). Here, we report the first observation of p-shell carrier assisted DNP in single QDs at zero external magnetic field. The nuclear field - measured by using the Overhauser shift of the singly charged exciton state of the QDs - continues to increase, even after the carrier population in the s-shell saturates. This is also accompanied by an abrupt increase in nuclear spin buildup time as p-shell emission overtakes that of the s-shell. We attribute the observation to p-shell electrons strongly altering the nuclear spin dynamics in the QD, supported by numerical simulation results based on a rate equation model of coupling between electron and nuclear spin system. DNP with p-shell carriers could open up avenues for further control to increase the degree of nuclear spin polarization in QDs.

description: A sequence of $d+1$ signs $+$ and $-$ beginning with a $+$ is called a {\em sign pattern (SP)}. We say that the real polynomial $P:=x^d+\sum _{j=0}^{d-1}a_jx^j$, $a_j\neq 0$, defines the SP $σ:=(+$,sgn$(a_{d-1})$, $\ldots$, sgn$(a_0))$. By Descartes' rule of signs, for the quantity $pos$ of positive (resp. $neg$ of negative) roots of $P$, one has $pos\leq c$ (resp. $neg\leq p=d-c$), where $c$ and $p$ are the numbers of sign changes and sign preservations in $σ$; the numbers $c-pos$ and $p-neg$ are even. We say that $P$ realizes the SP $σ$ with the pair $(pos, neg)$. For SPs with $c=2$, we give some sufficient conditions for the (non)realizability of pairs $(pos, neg)$ of the form $(0,d-2k)$, $k=1$, $\ldots$, $[(d-2)/2]$.

description: The target of this investigation is to evaluate the potential of Meyer Burger’s Heterojunction
Technology on p-type wafers with respect to cell performance and production cost. Since our first research results
indicate that production of HJT cells on 6-inch p-type CZ wafers with efficiencies above 20% is possible this would
enable a production of p-type HJT with a slight cost advantage of over existing high efficiency p-type technologies
especially PERC. Meyer Burger’s HJT equipment can be used for p-type HJT in the same configuration as for the above
22% n-type HJT with slight adaptations in process recipes, thus given the equipment and the technology an even larger
flexibility. We obtained a champion device for a bifacial p-type HJT cells with 20.4% which to our knownledge is the so
far highest efficiency reported on a 6-inch CZ p-type wafer for this kind of cell technology.

description: Does quantum theory apply at all scales, including that of observers? New light on this fundamental question has recently been shed through a resurgence of interest in the long-standing Wigner's friend paradox. This is a thought experiment addressing the quantum measurement problem -- the difficulty of reconciling the (unitary, deterministic) evolution of isolated systems and the (non-unitary, probabilistic) state update after a measurement. Here, by building on a scenario with two separated but entangled friends introduced by Brukner, we prove that if quantum evolution is controllable on the scale of an observer, then one of 'No-Superdeterminism', 'Locality' or 'Absoluteness of Observed Events' -- that every observed event exists absolutely, not relatively -- must be false. We show that although the violation of Bell-type inequalities in such scenarios is not in general sufficient to demonstrate the contradiction between those three assumptions, new inequalities can be derived in a theory-independent manner, that are violated by quantum correlations. This is demonstrated in a proof-of-principle experiment where a photon's path is deemed an observer. We discuss how this new theorem places strictly stronger constraints on physical reality than Bell's theorem.

This ultimate capacity is compared with corresponding results for heterodyne and homodyne detection over the same channel.

Silicon Solar Cell Characterisation and Modelling

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 799-803
description: In this work we discuss the dependencies of temperature coefficients of Si-solar cells on spectrum, temperature and irradiance. We investigate how the coefficient of the short-circuit current, , depends on spectral irradiance and quantum efficiency of the device under test. Therefore we measure the spectral resolved temperature coefficients of different cell types. The resulting spectral resolved , (), is observed to coincide within the measurement uncertainties for the cell types investigated. The irradiance and temperature dependence of the coefficient of open-circuit voltage, , and the different contributions to the temperature related changes in FF are discussed. Using highly precise temperature coefficient measurements we propose a parametrization of  that allows us to calculate temperature coefficients over a wide range of conditions with high accuracy.

description: We present spectropolarimetric observations of the nearby Type Ia SN 2014J in M82 over six epochs: +0, +7, +23, +51, +77, +109, and +111 days with respect to B-band maximum. The strong continuum polarization, which is constant with time, shows a wavelength dependence unlike that produced by linear dichroism in Milky Way dust. The observed polarization may be due entirely to interstellar dust or include a circumstellar scattering component. We find that the polarization angle aligns with the magnetic field of the host galaxy, arguing for an interstellar origin. Additionally, we confirm a peak in polarization at short wavelengths that would imply $R_V < 2 $ along the light of sight, in agreement with earlier polarization measurements. For illustrative purposes, we include a two component fit to the continuum polarization of our +51 day epoch that combines a circumstellar scattering component with interstellar dust where scattering can account for over half of the polarization at $4000$ Å. Upon removal of the interstellar polarization signal, SN 2014J exhibits very low levels of continuum polarization. Asymmetries in the distribution of elements within the ejecta are visible through moderate levels of time-variable polarization in accordance with the Si II 6355 Åabsorption line. At maximum light, the line polarization reaches $\sim0.6$% and decreases to $\sim0.4\%$ one week later. This feature also forms a loop on the $q_{RSP}$-$u_{RSP}$ plane illustrating that the ion does not have an axisymmetric distribution. The observed polarization properties suggest the explosion geometry of SN 2014J is generally spheroidal with a clumpy distribution of silicon.

Silicon Solar Cell Characterisation and Modelling

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 808-812
description: The non-uniformity of the BSG (borosilicate glass) layer formed during BBr3 tube diffusion is one of
the major concerns for solar cell fabrication, as the BSG layer serves as the dopant source and thus determines the
amount of boron dopants that are available. It is beneficial to have a deep understanding on the correlation between
the properties of the BSG layer and the resulting doping profile. Process simulations on tube diffusion are of great
relevance for the optimisation of industrial n-type solar cells. However, the simulation models and parameters were
mostly calibrated for CMOS (Complementary Metal Oxide Semiconductor) device fabrication. In this work, we
present an investigation on the influence of BSG non-uniformity on the resulting doping profiles. We demonstrate
with both experiments and by simulations that the doping profiles are not strongly affected by the non-uniformity of
the BSG layer once the BSG thickness is beyond a threshold. We present a set of model and parameters that is
suitable for accurately predictive simulation for solar cell fabrication. In addition, the sensitivity of the key modelling
parameters is discussed and reported.
Relationship between Pairing Symmetries and Interaction Parameters in Iron-Based Superconductors from Functional Renormalization Group Calculations

description: Pairing symmetries of iron-based superconductors are investigated systematically in a five-orbital model within the different regions of interaction parameters by functional renormalization group(FRG). Even for a fixed Fermi surface with both hole and electron pockets, it is found that depending on interaction parameters, a variety of pairing symmetries, including two types of $d$-wave and two types of $s$-wave pairing symmetries, can emerge. Only the $d_{x^2-y^2}$ and the $s\pm$ waves are robustly supported by the nearest-neighbor(NN) intra-orbital $J_1$ and the next-nearest-neighbor(NNN) intra-orbital $J_2$ antiferromagnetic(AFM) exchange couplings respectively. This study suggests that the accurate initial input of interaction parameters are essential to make FRG an useful method to determine the leading channel of superconducting instability.

description: We perform both analytical and numerical bifurcation analysis of a forest-grassland ecosystem model coupled with human interaction. The model consists of two nonlinear ordinary differential equations incorporating the human perception of forest/grassland value. The system displays multiple steady states corresponding to different forest densities as well as regimes characterized by both stable and unstable limit cycles. We derive analytically the conditions with respect to the model parameters that give rise to various types of codimension-one criticalities such as transcritical, saddle-node, and Andronov-Hopf bifurcations and codimension-two criticalities such as cusp and Bogdanov-Takens bifurcations. We also perform a numerical continuation of the branches of limit cycles. By doing so, we reveal turning points of limit cycles marking the appearance/disappearance of sustained oscillations. These far-from-equilibrium criticalities that cannot be detected analytically give rise to the abrupt loss of the sustained oscillations, thus leading to another mechanism of catastrophic shifts

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 813-816
description: The study deals with reducing the emitter dark current in high efficiency p+/n junction silicon solar cells. It is suggested and confirmed that an exponential doping profile in the emitter would lead to a better cell performance than a Gaussian doping profile in cells with a sheet resistance in the typical range 40 < Rsheet < 800 /square. It is shown using PC1D simulations that bulk recombination in emitters within this typical range of sheet resistance contributes with a significant part to the emitter dark current especially if the surface is well passivated. In such a case, for similar surface doping concentration and sheet resistance the emitter dark current is smaller and the open circuit voltage is higher in cells with an exponential than with a Gaussian emitter doping profile. The merit of the exponential profile stems from the fast drop in doping concentration close to the surface which leads to smaller bandgap narrowing and longer lifetime in the very influencing emitter surface region. In cells with a high sheet resistance (> 500 /square) and very shallow emitters both profiles practically lead to the same performance since bulk recombination in the emitter is negligible and the current becomes mainly dominated by surface recombination, equal in both profiles.

description: This paper demonstrates a contactless method to determine spatially resolved light trapping properties of silicon wafers. The technique is based on the comparison of two photoluminescence images measured using different excitation wavelengths. The first excitation wavelength is strongly absorbed in silicon (808 nm) and is used to account for recombination losses, the second excitation wavelength (1060 nm) is only partially absorbed within the silicon and used to determine light trapping. The method is compared to transflectance measurements on passivated polished silicon wafers, and good agreement is demonstrated. The method is then applied to determine spatial variations in light trapping of specially made test structures.
