description: Recent acoustic and electrical-circuit experiments have reported the third-order (or octupole) topological insulating phase, while its counterpart in classical magnetic systems is yet to be realized. Here we explore the collective dynamics of magnetic vortices in three-dimensional breathing cuboids, and find that the vortex lattice can support zero-dimensional corner states, one-dimensional hinge states, two-dimensional surface states, and three-dimensional bulk states, when the ratio of alternating intralayer and interlayer bond lengths goes beyond a critical value. We show that only the corner states are stable against external frustrations because of the topological protection. Full micromagnetic simulations verify our theoretical predictions with good agreement.

description: Dye-doped guest-host liquid crystal (GHLC) light shutters are widely used for privacy protection (windows) and sunlight blocking because of their low power consumption and fast response speed. The mesogenic molecule 4-(4-Heptylphenyl) benzoic acid (4HPB) can form hydrogen bonds with a vertical PI alignment layer to create a superhydrophobic vertical alignment (polyimide) PI layer, which can improve the order parameters of the dye. Because the initial transmittance and contrast of the GHLC are proportional to its own order parameters, the addition of the mesogenic molecule 4HPB can increase both the initial transmittance and contrast of the GHLC significantly. Moreover, the addition of 4HPB can also greatly increase the ion concentration of the GHLC, which introduces an electro-hydrodynamic effect. The GHLC can be switch states between transparent, haze-free dark, and high-haze dark by changing the strength of the applied voltage of appropriate frequency. Double-layered guest-host liquid crystal (DGHLC), doped with mesogenic molecules, are suitable for fast-moving applications (such as cars and airplanes) due to their short response time and high-order parameters.

description: Depending upon the properties of their compact remnants and the physics included in the models, simulations of neutron star mergers can produce a broad range of ejecta properties. The characteristics of this ejecta, in turn, define the kilonova emission. To explore the effect of ejecta properties, we present a grid of 2-component 2D axisymmetric kilonova simulations that vary mass, velocity, morphology, and composition. The masses and velocities of each component vary, respectively, from 0.001 to 0.1 M$_{\odot}$ and 0.05 to 0.3$c$, covering much of the range of results from the neutron star merger literature. The set of 900 models is constrained to have a toroidal low electron fraction ($Y_e$) ejecta with a robust r-process composition and either a spherical or lobed high-$Y_e$ ejecta with two possible compositions. We simulate these models with the Monte Carlo radiative transfer code SuperNu using a full suite of lanthanide and 4th row element opacities. We examine the trends of these models with parameter variation, show how it can be used with statistical tools, and compare the model light curves and spectra to those of AT2017gfo, the electromagnetic counterpart of GW170817.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 3243-3246
description: Today the market is open to new solutions that integrate solar thermal and photovoltaic (PV) devices
into a single element in order to generate electricity and thermal energy, the so-called photovoltaic thermal (PVT)
hybrid solar collectors, or simply hybrid modules. The PVT modules can improve the performance of the PV part due
to the cooling of PV cells. A test-stand for hybrid PVT systems was design to develop new solutions and for better
understanding their performance under real operating conditions. An innovative low-cost prototype of PVT module
was developed using a radiant pipe system with a liquid heat-transfer medium used to cool photovoltaic cells. To
improve the module design and to check their thermal behaviour for typical domestic hot-water systems, two
different PVT solutions were compared with an identical PV module without the heat transfer system. The new stand
test was used in order to test the overall performance of the modules. The characteristics of two different collector
types are here described by the authors.

description: We investigate the close relationship between minimal surfaces in Euclidean 3-space and constant mean curvature 1 surfaces in hyperbolic 3-space. Just as in the case of minimal surfaces in Euclidean 3-space, the only complete connected embedded constant mean curvature 1 surfaces with two ends in hyperbolic space are well-understood surfaces of revolution -- the catenoid cousins. In contrast to this, we show that, unlike the case of minimal surfaces in Euclidean 3-space, there do exist complete connected immersed constant mean curvature 1 surfaces with two ends in hyperbolic space that are not surfaces of revolution -- the genus 1 catenoid cousins. The genus 1 catenoid cousins are of interest because they show that, although minimal surfaces in Euclidean 3-space and constant mean curvature 1 surfaces in hyperbolic 3-space are intimately related, there are essential differences between these two sets of surfaces (when the surfaces are considered globally). The proof we give of existence of the genus 1 catenoid cousins is a mathematically rigorous verification that the results of a computer experiment are sufficiently accurate to imply existence.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1579-1581
description: Over the last few years, large-area AlOx/SiNx stack rear passivated solar cells have been demonstrated in many R&D laboratories. The key point to achieve high-efficiency Passivated Emitter and Rear Contact (PERC) solar cells is to minimize the contact resistance while retaining the passivation performance at the rear surface. This paper reports on the development on the industrial scale of PERC cells based on laser ablation combined with screen
printing metallization technology. The impact of laser opening area to the passivation quality and contact resistance is investigated by changing the line width of laser openings. It is found that the effective lifetime increases with decreasing the line width of laser ablation, while the series resistance stays constant in IV characteristics. Scanning electron microscopy images also indicated that the local BSF is more homogenous with narrow line width. The optimum rear line contact scheme was achieved with a maximum cell efficiency of 19.6% for solar cells fabricated on
156.5×156.5mm2 p-type casting-mono silicon wafers, corresponding to an absolute gain of 1.0% compared to the
reference cells with full area Al-BSF.

description: In this paper we shall study quantum critical behavior of lattice model of unconventional superconductors (SC) that was proposed in the previous papers. In this model, the Cooper-pair (CP) field is defined on lattice links in order to describe d-wave SC. The CP field can be regarded as a U(1) lattice gauge field, and the SC phase transition takes place as a result of the phase coherence of the CP field. Effects of the long-range Coulomb interactions between the CP's and fluctuations of the electromagnetic field are taken into account. We investigate the phase structure of the model and the critical behavior by means of the Monte Carlo simulations. We find that the parameter, which controls the fluxes (vortices) of the CP, strongly influences the phase structure. In three-dimensional case, the model has rich phase structure. In particular there is a "monopole proliferation" phase transition besides the SC phase transition. Depending on the parameters, this transition exists within the SC phase or takes place simultaneously with the SC transition. This new type of transition is relevant for unconventional SC's with strong spatial three-dimensionality and to be observed by experiments.

description: Satellite remote sensing is playing an increasing role in the rapid mapping of damage after natural disasters. In particular, synthetic aperture radar (SAR) can image the Earth's surface and map damage in all weather conditions, day and night. However, current SAR damage mapping methods struggle to separate damage from other changes in the Earth's surface. In this study, we propose a novel approach to damage mapping, combining deep learning with the full time history of SAR observations of an impacted region in order to detect anomalous variations in the Earth's surface properties due to a natural disaster. We quantify Earth surface change using time series of Interferometric SAR coherence, then use a recurrent neural network (RNN) as a probabilistic anomaly detector on these coherence time series. The RNN is first trained on pre-event coherence time series, and then forecasts a probability distribution of the coherence between pre- and post-event SAR images. The difference between the forecast and observed co-event coherence provides a measure of the confidence in the identification of damage. The method allows the user to choose a damage detection threshold that is customized for each location, based on the local behavior of coherence through time before the event. We apply this method to calculate estimates of damage for three earthquakes using multi-year time series of Sentinel-1 SAR acquisitions. Our approach shows good agreement with observed damage and quantitative improvement compared to using pre- to co-event coherence loss as a damage proxy.

Quantum phase transitions, entanglement, and geometric phases of two qubits
Creators: name: Oh, Sangchul

Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The relation between quantum phase transitions, entanglement, and geometric phases is investigated with a system of two qubits with XY type interaction. A seam of level crossings of the system is a circle in parameter space of the anisotropic coupling and the transverse magnetic field, which is identical to the disorder line of an one-dimensional XY model. The entanglement of the ground state changes abruptly as the parameters vary across the circle except specific points crossing to the straight line of the zero magnetic field. At those points the entanglement does not change but the ground state changes suddenly. This is an counter example that the entanglement is not alway a good indicator to quantum phase transitions. The rotation of the circle about an axis of the parameter space produces the magnetic monopole sphere like a conducting sphere of electrical charges. The ground state evolving adiabatically outside the sphere acquires a geometric phase, whereas the ground state traveling inside the sphere gets no geometric phase. The system also has the Renner-Teller intersection which gives no geometric phases.

description: Encapsulation film plays a key role in the protection of a PV module. Thermal stability, resistance to
moisture, stability against UV degradation, and electrical protection are all important components. A
polyolefinbased encapsulation film has been developed which has improved performance in these areas as compared
to EVA encapsulation film. Optical transmission and color generation of films were studied after accelerated UV
exposure. Significantly less generation of yellow color was observed and optical transmission was more stable with
the polyolefin film. Lower film water vapor transmission rate results in improved module damp heat performance.
Higher film electrical resistivity is shown to correlate with improvements in module PIDresistance. The polyolefin
film also has a lower UVcutoff, offering the potential for improved power generation.

Solar Cells, Modules and PV Systems for Space Applications

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 95-98
description: Inverted metamorphic multi-junction (IMM) solar cells have achieved the highest efficiency for space applications (NASA confirmed 33.9% for 1 sun, AM0), and nearly the highest efficiency for terrestrial high concentration applications (NREL confirmed 42.4% for 325x, ASTM G173 direct). Achieving higher efficiencies for space applications is mission enabling, allowing for larger payloads for the same sized solar arrays. Higher efficiency
is the primary driver for cost reduction for power generation in terrestrial concentrator systems. The IMM approach allows for the addition of metamorphic junctions creating a device with a more optimal match to the incoming spectrum, thereby increasing conversion efficiency. The required removal of the growth substrate during processing allows for very thin devices. The thin devices have very high specific power, useful for space applications, and if
attached to a heat sink have a reduced temperature operation in terrestrial concentrator applications. We report on the latest IMM cell developments, performance, and packaging.

description: We investigate the role of the boundary in the symmetric simple exclusion process with competing nonlocal and local hopping events. With open boundaries, the system undergoes a first order phase transition from a finite density phase to an empty road phase as the nonlocal hopping rate increases. Using a cluster stability analysis, we determine the location of such an abrupt nonequilibrium phase transition, which agrees well with numerical results. Our cluster analysis provides a physical insight into the mechanism behind this transition. We also explain why the transition becomes discontinuous in contrast to the case with periodic boundary conditions, in which the continuous phase transition has been observed.

description: We present molecular line observations of L1251B, a small group of pre- and protostellar objects, and its immediate environment in the dense C18O core L1251E. These data are complementary to near-infrared, submillimeter and millimeter continuum observations reported by Lee et al. (2006, ApJ, 648, 491; Paper I). The single-dish data of L1251B described here show very complex kinematics including infall, rotation and outflow motions, and the interferometer data reveal these in greater detail. Interferometer data of N2H+ 1-0 suggest a very rapidly rotating flattened envelope between two young stellar objects, IRS1 and IRS2. Also, interferometer data of CO 2-1 resolve the outflow associated with L1251B seen in single-dish maps into a few narrow and compact components. Furthermore, the high resolution data support recent theoretical studies of molecular depletions and enhancements that accompany the formation of protostars within dense cores. Beyond L1251B, single-dish data are also presented of a dense core located ~150" to the east that, in Paper I, was detected at 850 micron but has no associated point sources at near- and mid-infrared wavelengths. The relative brightness between molecules, which have different chemical timescales, suggests it is less chemically evolved than L1251B. This core may be a site for future star formation, however, since line profiles of HCO+, CS, and HCN show asymmetry with a stronger blue peak, which is interpreted as an infall signature.

description: PbTe crystals have a soft transverse optical phonon mode in the terahertz frequency range, which is known to efficiently decay into heat-carrying acoustic phonons, resulting in anomalously low thermal conductivity. Here, we studied this phonon via polarization-dependent terahertz spectroscopy. We observed softening of this mode with decreasing temperature, indicative of incipient ferroelectricity, which we explain through a model including strong anharmonicity with a quartic displacement term. In magnetic fields up to 25T, the phonon mode split into two modes with opposite handedness, exhibiting circular dichroism. Their frequencies displayed Zeeman splitting together with an overall diamagnetic shift with increasing magnetic field. Using a group-theoretical approach, we demonstrate that these observations are results of magnetic field-induced morphic changes in the crystal symmetries through the Lorentz force exerted on the lattice ions. This study thus reveals a novel process of controlling phonon properties in a soft ionic lattice by a strong magnetic field.

solar cells have been manufactured and tested. The optical reflection can be decreased to 5%. The optical
property and current-voltage (I-V) measurement indicate that the Si nanostructure-textured solar cells will
promisingly exhibit good performance if better passivation and electrode contact were provided. This fabrication
method of Si nanostructures could open potential application in photovoltaic.

description: Nonequilibrium steady states (NESSs) in periodically driven dissipative quantum systems are vital in Floquet engineering. We develop a general theory for high-frequency drives with Lindblad-type dissipation to characterize and analyze NESSs based on the high-frequency (HF) expansion with linear algebraic numerics and without numerically solving the time evolution. This theory shows that NESSs can deviate from the Floquet-Gibbs state depending on the dissipation type. We show the validity and usefulness of the HF-expansion approach in concrete models for a diamond nitrogen-vacancy (NV) center, a kicked open XY spin chain with topological phase transition under boundary dissipation, and the Heisenberg spin chain in a circularly-polarized magnetic field under bulk dissipation. In particular, for the isotropic Heisenberg chain, we propose the dissipation-assisted terahertz (THz) inverse Faraday effect in quantum magnets. Our theoretical framework applies to various time-periodic Lindblad equations that are currently under active research.

description: Many developers both from India and abroad have come forward for installing 5-25 MWP PV power
plant at the Gujarat Solar Park situated in the western part of India. The accumulated participations were projected
with a total capacity in developing 500 MWP grid exported PV power system. Each of the plant is dedicated to
convert photo generated DC power into AC power through its appropriate inverting systems. The inverted power
then stepped up into 11 kV by compact secondary sub-stations and finally stepped up to 11 kV for feeding into the
11 / 66 kV switch yard for efficient exporting into the Gujarat Energy Transmitting Corporation (GETCO) grid.
The PV power plants along with their auxiliary systems were set up on the salt marsh land around the Little Rann
of Kutch of Gujarat. The accumulated power plant is a mixture of PV modules made up either from poly
crystalline Si or thin film CdTe and amorphous Si materials. Each of the developers was allotted 5-8 acres of land
per MWP for setting up their plant depending upon the quality of PV module used by them. The projected plant life
is 25 years and the state Govt. has agreed to purchase the generated power @ Indian Rupee (INR) 15.00 per kWh
(56 INR = 1 US$) for first 12 years and INR 5.00 per kWh for remaining 13 years with levelized tariff INR 13.30
per kWh for 25 years. The environmental issues related to the installation and operation phases and possible
uncertainties in power production from such facilities have not, so far, been addressed comprehensively in the
literature. One of such 10 MWP polycrystalline Si power plant was considered under present studies to enlighten
the above issues and is presented in the text of the present paper.

description: Precise potentials for the ground state X1Sigma+g and the minimum region of the excited state 2_1Sigma+u of Sr2 are derived by high resolution Fourier-transform spectroscopy of fluorescence progressions from single frequency laser excitation of Sr2 produced in a heat pipe at 950 Celsius. A change of the rotational assignment by four units compared to an earlier work (G. Gerber, R. Möller, and H. Schneider, J. Chem. Phys. 81, 1538 (1984)) is needed for a consistent description leading to a significant shift of the potentials towards longer inter atomic distances. The huge amount of ground state data derived for the three different isotopomers 88Sr2, 86Sr88Sr and 87Sr88Sr (almost 60% of all excisting bound rovibrational ground state levels for the isotopomer 88Sr2) fixes this assignment undoubtedly. The presented ground state potential is derived from the observed transitions for the radial region from 4 to 11 A (9 cm-1 below the asymptote) and is extended to the longe range region by the use of theoretical dispersion coefficients together with already available photoassociation data. New estimations of the scattering lengths for the complete set of isotopic combinations are derived by mass scaling with the derived potential. The data set for the excited state 2_1Sigma+u was sufficient to derive a potential energy curve around the minimum.

description: It is well known that the basic request of PV crystalline silicon ingot or wafer is higher quality and
lower cost. Therefore, if we want to develop the high efficiency solar cell over 19%, the mono wafer from
Czochralski (CZ) puller is one of key technology, however, by comparison with heat exchanger method (HEM) for
multi-crystalline or mono-casting, the weakness of CZ puller is lower productivity and higher running cost. So, the
motivation and purpose of this work is trying to improve the productivity of CZ puller and reduce its running cost. In
this work, we adopt the multiple recharges process by “internal feeder” to our experiments and achieve 30% cost
reduction and 30% productivity improvement after new got zone design and multiple recharge process
implementation. Besides cost reduction, we checked the qualities of 3 continuous growth ingots from one crucible
after over 120hrs heating process, the results are shown the last ingot pulled out from the crucible can retain similar
quality performances to the initial ingot at proper hot zone design [1.2] and recharges process control.

description: We study the quantum metric tensor and its scalar curvature for a particular version of the Lipkin-Meshkov-Glick model. We build the classical Hamiltonian using Bloch coherent states and find its stationary points. They exhibit the presence of a ground state quantum phase transition, where a bifurcation occurs, showing a change of stability associated with an excited state quantum phase transition. Symmetrically, for a sign change in one Hamiltonian parameter, the same phenomenon is observed in the highest energy state. Employing the Holstein-Primakoff approximation, we derive analytic expressions for the quantum metric tensor and compute the scalar and Berry curvatures. We contrast the analytic results with their finite-size counterparts obtained through exact numerical diagonalization and find an excellent agreement between them for large sizes of the system in a wide region of the parameter space, except in points near the phase transition where the Holstein-Primakoff approximation ceases to be valid.

Relativistic Fluctuation Theorems: Theory and explicit examples

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: To reveal how nonequilibrium physics and relativity theory intertwine, this articles studies relativistic Brownian motion under cosmic expansion. Two fluctuation theorems for the entropy ds, which is locally produced in this extreme nonequilibrium situation, are presented and proven. The first, =1, is a generalization of the second law of thermodynamics, that remains valid at relativistic particle energies and under high cosmic expansion rates. From this relation follows, that the probability to observe a local reduction of entropy is exponentially small even if the universe was to recollapse. For the special case of the Einstein-de Sitter universe an additional relation, =1, is derived which holds simultaneously with the first relation and where dh is proportional to the Hubble constant. Furthermore, the fluctuation theorems are shown to provide a physical criterion to resolve the known discretization dilemma arising in special-relativistic Brownian motion. Explicit examples and a general method for the computation of non-Gaussian entropy fluctuations are provided.

description: Accidents are a leading cause of deaths in armed forces. The Aim of this paper is to minimize the accidents caused using weapons in the armed forces. Developing artificial intelligence technologies aim to increase efficiency more and more wherever people exist. Giving guns to inexperienced, untrained, or unpredictable mentally unhealthy people in shooting ranges used for gun training can be risky and fatal. With the use of image processing technologies in these shooting ranges, it is aimed to minimize the risk of life-threatening accidents that may be caused by this people. Artificial intelligence is trained for the targets to be used in shooting ranges. When the camera of weapon sees these targets, it switches from safe mode to firing mode. When a risky situation occurs in shooting range, the gun turns itself into safe mode with various additional security measures.

description: In this thesis I argue that an architecture that selectively intervenes in the aging landscape to provide opportunities for regeneration and mentorship can weaken our societal divisions.  I tested this hypothesis in the context of an adaptive reuse, multi-generational, mixed use design for the Bailey Power Plant, Factory 60, and their surroundings: the former R.J. Reynolds tobacco district in my hometown of Winston-Salem, North Carolina. After a close study of the site's history and its urban morphology, I propose a design based on the concept of urban regeneration in the form of reclamation, adaptation, and mentorship established through a system of green infrastructure that weaves existing neighborhoods into new diverse, multi-generational communities, housed within existing but altered architecture.

description: For evaluation of the characteristics of photovoltaic cells, the solar simulator is adjusted to 1 kW/m²
utilizing a reference cell. We developed a Spectral Reference Cell method which can be used for adjustment of solar
simulator intensity for testing photovoltaic cells without using specific reference cells. This method adjusts the
intensity of a solar simulator with various spectral responsivities. We improved the measurement system and obtained
a 2.6% Isc error for 9 different cells. We then expanded this method to non-linear photovoltaic cells by using DSR
(Differential Spectral Responsivity) method. We were able to adjust the intensity within 3 % error.

description: Let A be a ring of dimension d and let P be a projective A-module of rank d. We prove that if for every finite extension R of A, R^d is cancellative, then P is cancellative. This gives an alternate proof of Bhatwadekar's result: every projective module of rank d over an affine algebra of dimension d over a C_1-field of characteristic 0 is cancellative. Let P be a projective module of rank d-1 over an affine agebra of dimension d over an algebraically closed field. Then, it is not known if P is cancellative. We prove some results in this direction also.

description: Although traditional models of epidemic spreading focus on the number of infected, susceptible and recovered individuals, a lot of attention has been devoted to integrate epidemic models with population genetics. Here we develop an individual-based model for epidemic spreading on networks in which viruses are explicitly represented by finite chains of nucleotides that can mutate inside the host. Under the hypothesis of neutral evolution we compute analytically the average pairwise genetic distance between all infecting viruses over time. We also derive a mean-field version of this equation that can be added directly to compartmental models such as SIR or SEIR to estimate the genetic evolution. We compare our results with the inferred genetic evolution of SARS-CoV-2 at the beginning of the epidemic in China and found good agreement with the analytical solution of our model. Finally, using genetic distance as a proxy for different strains, we use numerical simulations to show that the lower the connectivity between communities, e.g., cities, the higher the probability of reinfection.
