description: A meteorologically challenging situation that represents a demanding control task (rotational speed, pitch and yaw) for a wind turbine is presented and its implementation in a simulation is described. A high-fidelity numerical process chain, consisting of the computational fluid dynamics (CFD) solver FLOWer, the multi-body system (MBS) software SIMPACK and the Ffowcs Williams-Hawkings code ACCO, is used. With it, the aerodynamic, servoelastic and aeroacoustic (<20 Hz) behaviour of a generic wind turbine during a meteorological event with strong and rapid changes in wind speed and direction is investigated. A precursor simulation with the meteorological model system PALM is deployed to generate realistic inflow data. The simulated strong controller response of the wind turbine and the resulting aeroelastic behaviour are analysed. Finally, the low-frequency sound emissions are evaluated and the influence of the different operating and flow parameters during the variable inflow is assessed. It is observed that the wind speed and, linked to it, the rotational speed as well as the turbulence intensity are the main influencing factors for the emitted low-frequency sound power of the wind turbine. Yawed inflow, on the other hand, has little effect unless it changes the operational mode to load reduction, resulting in a swap of the main emitter from the blades to the tower.

description: A common approach to studying the performance of quantum error correcting codes is to assume independent and identically distributed single-qubit errors. However, the available experimental data shows that realistic errors in modern multi-qubit devices are typically neither independent nor identical across qubits. In this work, we develop and investigate the properties of topological surface codes adapted to a known noise structure by Clifford conjugations. We show that the surface code locally tailored to non-uniform single-qubit noise in conjunction with a scalable matching decoder yields an increase in error thresholds and exponential suppression of sub-threshold failure rates when compared to the standard surface code. Furthermore, we study the behaviour of the tailored surface code under local two-qubit noise and show the role that code degeneracy plays in correcting such noise. The proposed methods do not require additional overhead in terms of the number of qubits or gates and use a standard matching decoder, hence come at no extra cost compared to the standard surface-code error correction.

description: We investigate the history of the thermomechanical stresses in the seed area during the melting and solidification steps of monolike ingot processing. This is specifically relevant to understand dislocation densities and microstructures at the beginning of growth of such ingots. We found that Von Mises (VM) stresses in seeds are highest at the onset of melting and sufficient to generate dislocation multiplication in seeds before growth begins. As large stresses before growth start might explain the high experimental local dislocations densities in seeds, we also focused on several mechanical boundary conditions applied to the seed for the VM calculations during the heating stage. Results show that locally fixed boundary and arbitrary locally loaded seed conditions used in simulations are significant compared to pure thermally induced stresses.

description: Deep sub micron HV-CMOS processes offer the opportunity for sensors built by industry standard techniques while being HV tolerant, making them good candidates for drift-based, fast collecting, thus radiation-hard pixel detectors. For the upgrade of the ATLAS Pixel Detector towards the HL-LHC requirements, active pixel sensors in HV-CMOS technology were investigated. These implement amplifier and discriminator stages directly in insulating deep n-wells, which also act as collecting electrodes. The deep n-wells allow for bias voltages up to 150V leading to a depletion depth of several 10um. Prototype sensors in the ams H18 180nm and H35 350nm HV-CMOS processes have been manufactured, acting as a potential drop-in replacement for the current ATLAS Pixel sensors, thus leaving higher level processing such as trigger handling to dedicated read-out chips. Sensors were thoroughly tested in lab measurements as well as in testbeam experiments. Irradiation with X-rays and protons revealed a tolerance to ionizing doses of 1Grad. An enlarged depletion zone of up to 100um thickness after irradiation due to the acceptor removal effect was deduced from Edge-TCT studies. The sensors showed high detection efficiencies after neutron irradiation to 1e15 n_eq cm-2 in testbeam experiments. A full reticle size demonstrator chip, implemented in the H35 process is being submitted to prove the large scale feasibility of the HV-CMOS concept.

Crossover from Shear-Driven to Thermally Activated Drainage of Liquid-Infused Microscale Capillaries

description: The shear-driven drainage of capillary grooves filled with viscous liquid is a dynamic wetting phenomenon relevant to numerous industrial processes and novel lubricant-infused surfaces. Prior work has reported that a finite length $L_\infty$ of the capillary groove can remain indefinitely filled with liquid even when large shear stresses are applied. The mechanism preventing full drainage is attributed to a balance between the shear-driven flow and a counterflow driven by capillary pressures caused by deformation of the free surface. The final equilibrium length $L_\infty$ is uniquely determined by physical properties of the filling liquid as well as the geometry and wettability of the capillary. In this work, we examine closely the approach to the final equilibrium length $L_\infty$ and report a crossover to a slow drainage regime that cannot be described by conventional dynamic models considering solely hydrodynamic and capillary forces. The slow drainage regime observed in experiments can be instead modeled by a kinetic equation describing a sequence of random thermally activated transitions between multiple metastable states caused by surface defects with nanoscale dimensions. Our findings provide new insights on the critical role that natural or engineered surface roughness with nanoscale dimensions can play in the imbibition and drainage of capillaries and other dynamic wetting processes in microscale systems.

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 604-609
description: This works focuses on the introduction of selective epitaxy as a contact passivation approach for bifacial
n-type PERT solar cells. Because of the use of a metal grid on their rear side, bifacial cells provide a higher energy
yield through rear illumination but have larger recombination losses than their monofacial counterparts with point
contacts. A breakdown analysis of the recombination losses in bifacial cells fabricated with a homogeneous emitter,
and for which efficiency values above 22.5 % were already achieved, reveals that there is still an important contribution
of the emitter J0,metal (3000-4000 fA/cm2 for 1.2 % metal contact fraction) and that the emitter J0,pass can also be further
improved to increase efficiency. This works aims at reducing the recombination losses in these devices by introducing
in one single step an epitaxially grown highly doped layer at the p-type regions to be contacted. The structures here
fabricated up to the step just prior to metallization (including patterning of both emitter and BSF) demonstrate the
potential of this approach to significantly reduce the recombination losses compared to the reference without a selective
epitaxial contact passivation scheme: (a) homogeneous emitter with SiO2 passivation: J0,total=90 fA/cm2, iVoc=681 mV,
(b) homogeneous emitter with Al2O3 passivation: J0,total=70 fA/cm2, iVoc=688 mV, and (c) selective emitter via selective
epitaxy with SiO2 passivation: J0,total=55 fA/cm2, iVoc=695 mV. Keeping in mind that this approach also brings the
possibility to independently optimize the emitter in the passivated regions to reduce Auger recombination, further gain
in passivation may still be possible, which increases the potential of this structure to achieve higher efficiency values
at cell level.

description: The Long Term Evolution (LTE) as a mobile broadband technology supports a wide domain of communication services with different requirements. Therefore, scheduling of all flows from various applications in overload states in which the requested amount of bandwidth exceeds the limited available spectrum resources is a challenging issue. Accordingly, in this paper, a greedy algorithm is presented to evaluate user candidates which are waiting for scheduling and select an optimal set of the users to maximize system performance, without exceeding available bandwidth capacity. The greedy-knapsack algorithm is defined as an optimal solution to the resource allocation problem, formulated based on the fractional knapsack problem. A compromise between throughput and QoS provisioning is obtained by proposing a class-based ranking function, which is a combination of throughput and QoS related parameters defined for each application. The simulation results show that the proposed method provides high performance in terms of throughput, loss and delay for different classes of QoS over the existing ones, especially under overload traffic.

description: In an effort to study the stability of contact lines in fluids, we consider the dynamics of an incompressible viscous Stokes fluid evolving in a two-dimensional open-top vessel under the influence of gravity. This is a free boundary problem: the interface between the fluid in the vessel and the air above (modeled by a trivial fluid) is free to move and experiences capillary forces. The three-phase interface where the fluid, air, and solid vessel wall meet is known as a contact point, and the angle formed between the free interface and the vessel is called the contact angle. We consider a model of this problem that allows for fully dynamic contact points and angles. We develop a scheme of a priori estimates for the model, which then allow us to show that for initial data sufficiently close to equilibrium, the model admits global solutions that decay to equilibrium exponentially fast.

A recent survey of the SMC under a Chandra X-ray Visionary program found the source in a transition when the X-ray flux was on a steady rise. The Lomb-Scargle periodogram revealed a pulse period of 211.49 +/- 0.42 s, which is significantly (>5sigma) shorter than the previous measurements with XMM-Newton and RXTE. This implies that the system has gone through sudden spin-up episodes recently. The pulse profile shows a sharp eclipse-like feature with a modulation amplitude of >95%.

description: Determination of lattice parameters from 3D electron diffraction (3D ED) data measured in a transmission electron microscope is hampered by a number of effects that seriously limit the achievable accuracy. The distortion of the diffraction patterns by the optical elements of the microscope is often the most severe problem. A thorough analysis of a number of experimental datasets shows that, in addition to the well known distortions, namely barrel-pincushion, spiral and elliptical, an additional distortion, dubbed parabolic, may be observed in the data. In precession electron diffraction data, the parabolic distortion leads to excitation-error-dependent shift and splitting of reflections. All distortions except for the elliptical distortion can be determined together with lattice parameters from a single 3D ED data set. However, the parameters of the elliptical distortion cannot be determined uniquely due to correlations with the lattice parameters. They can be determined and corrected either by making use of the known Laue class of the crystal or by combining data from two or more crystals. The 3D ED data can yield lattice parameter ratios with an accuracy of about 0.1% and angles with an accuracy better than 0.03◦.

description: We analyse the secular dynamics of planets on S-type coplanar orbits in tight binary systems, based on first- and second-order analytical models, and compare their predictions with full N-body simulations. The perturbation parameter adopted for the development of these models depends on the masses of the stars and on the semimajor axis ratio between the planet and the binary. We show that each model has both advantages and limitations. While the first-order analytical model is algebraically simple and easy to implement, it is only applicable in regions of the parameter space where the perturbations are sufficiently small. The second-order model, although more complex, has a larger range of validity and must be taken into account for dynamical studies of some real exoplanetary systems such as $γ$-Cephei and HD 41004A. However, in some extreme cases, neither of these analytical models yields quantitatively correct results, requiring either higher-order theories or direct numerical simulations. Finally, we determine the limits of applicability of each analytical model in the parameter space of the system, giving an important visual aid to decode which secular theory should be adopted for any given planetary system in a close binary.

description: Green flood retention measures (GFRMs) are nature-based solutions applied to. mitigate floods by slowing and storing floodwater. This study employed a hydraulic, model developed in HEC-RAS to analyze the effects of GFRMs in the Quebrada Seca-Burío basin in Costa Rica. A multi-criteria methodology was developed to select. suitable sites for implementing the measures. A baseline representing the status quo, scenarios with individually assessed measures implemented at different sites, and a scenario with all measures combined were compared concerning their flood retention. potential. Twelve suitable sites capable of providing multiple socio-ecological benefits. were identified, of which three were implemented in the model to evaluate their. hydraulic performance. The results indicate that all scenarios are effective in reducing. peak flow, volume, and inundation areas, but to varying degrees. The combination of. all measures presented the most effective results, with peak flow reductions of 5.6 –15.3% and flood volume reductions of 3.6 – 9.9%.

description: The interband optical response of a three-dimensional Dirac cone is linear in photon energy ($Ω$). Here, we study the evolution of the interband response within a model Hamiltonian which contains Dirac, Weyl and gapped semimetal phases. In the pure Dirac case, a single linear dependence is observed, while in the Weyl phase, we find two quasilinear regions with different slopes. These regions are also distinct from the large-$Ω$ dependence. As the boundary between the Weyl (WSM) and gapped phases is approached, the slope of the low-$Ω$ response increases, while the photon-energy range over which it applies decreases. At the phase boundary, a square root behaviour is obtained which is followed by a gapped response in the gapped semimetal phase. The density of states parallels these behaviours with the linear law replaced by quadratic behaviour in the WSM phase and the square root dependence at the phase boundary changed to $|ω|^{3/2}$. The optical spectral weight under the intraband (Drude) response at low temperature ($T$) and/or small chemical potential ($μ$) is found to change from $T^2$ ($μ^2$) in the WSM phase to $T^{3/2}$ ($|μ|^{3/2}$) at the phase boundary.

description: The interest in N-type solar cells has increased recently because of high efficiency and low lightinduced
degradation(LID). The back side of Bifacial N-type Si solar cells has to be highly doped phosphorous to
form back surface field (BSF), this results in low contact resistance and good fill factor. However, highly doped back
surface field increases surface recombination and then reduces the efficiency of cell. In this paper, N-type bifacial Si
solar cells with selective back surface field structure (SBSF) is presented. We developed an industrially feasible etch
back process to create a selective back surface field. the areas for back side metallization were shielded for etching by
an acid resistant etch barrier to achieve a low contact resistivity. The highly doped BSF was etched back by a wet
chemical process. The influences of several process parameters on cell efficiency were discussed. The performance
was improved in terms of both short-circuit current density (0.65mA/cm2)and open-circuit voltage(8mV), which
gives rise to 0.43% absolute efficiency gain compare to the cells with homogeneous BSF. It was shown that
improvement of cell performance was because of the better spectral response in long wavelength and lower back side
recombination.

description: We review the formalism underlying the modeling of gravitational wave (GW) polarizations, and the coordinate frames used to define them. In the process, we clarify the notion of "polarization angle" and identify three conceptually distinct definitions. We describe how those are related and how they arise in the practice of GW data analysis, explaining in detail the relevant conventions that have become the LIGO-Virgo standard. Furthermore, we show that any GW signal can be expressed as a superposition of elliptical (i.e., fully-polarized) states, and examine the properties and possible parametrizations of such elementary states. We discuss a variety of common parametrizations for fully-polarized modes, and compute Jacobians for the coordinate transformations relating them. This allows us to examine the suitability of each parametrization for different applications, including unmodeled or semimodeled signal reconstructions. We point out that analyses parametrized directly in terms of the plus and cross mode amplitudes will tend to implicitly favor high signal power, and to prefer linearly-polarized waves along a predefined direction; this makes them suboptimal for targeting face-on or face-off sources, which will tend to be circularly polarized. We discuss alternative parametrizations, with applications extending to continuous waves, ringdown studies, and unmodeled analyses like BayesWave. Code and additional material are made available in https://github.com/maxisi/gwpols.

description: This chapter presents a heuristic on how to distinguish between three modes of contestation of scientific evidence, knowledge and expertise in knowledge societies. The first mode of contestation questions the validity and reliability of scientific knowledge; the second one raises doubts that the specific scientific expertise is adequate for solving the political problem at hand; and the third one criticizes the scientific field's exposed position in matters of decision- and policy-making and administrative processes. The three forms of contestation have different effects on the recognition of science. In the first mode, scientific evidence is problematized. In the second mode, its political framing and usage is questioned, without denying the role of scientific evidence in political and administrative decision-making in principle. In the third mode, the relevance of scientific evidence for political decision-making is questioned.

description: Mouse haematopoietic stem cells (HSCs) first emerge at embryonic day 10.5 (E10.5), on the ventral surface of the dorsal aorta, by endothelial-to-haematopoietic transition. We investigated whether mesenchymal stem cells, which provide an essential niche for long-term HSCs (LT-HSCs) in the bone marrow, reside in the aorta-gonad-mesonephros and contribute to the development of the dorsal aorta and endothelial-to-haematopoietic transition. Here we show that mesoderm-derived PDGFRA+ stromal cells (Mesp1der PSCs) contribute to the haemogenic endothelium of the dorsal aorta and populate the E10.5-E11.5 aorta-gonad-mesonephros but by E13.5 were replaced by neural-crest-derived PSCs (Wnt1der PSCs). Co-aggregating non-haemogenic endothelial cells with Mesp1der PSCs but not Wnt1der PSCs resulted in activation of a haematopoietic transcriptional programme in endothelial cells and generation of LT-HSCs. Dose-dependent inhibition of PDGFRA or BMP, WNT and NOTCH signalling interrupted this reprogramming event. Together, aorta-gonad-mesonephros Mesp1der PSCs could potentially be harnessed to manufacture LT-HSCs from endothelium.

description: A novel structure of Ag grid/SiNx/n+-c-Si/n-c-Si/i-a-Si:H/p+-a-Si:H/TCO/Ag grid is designed in order
to increase the efficiency of bifacial amorphous silicon/crystalline silicon based solar cells (HJT) and reduce the rear
materials consumption and manufacture cost. The simulation result done by AFORS-HET shows that the new
structure could get higher efficiency compared with the normal bifacial HIT cell for the increase of the short circuit
current, while it could keep most advantages of the HJT, such as: high voltage, low temperature coefficient and good
weak light performance. A real cell composed of the novel structure with a size of 75mm*75mm was tried out by a
special processing recipe, in which most techniques and machines are normally used in c-Si solar cell manufacture.
Without any parameters optimization, the efficiency with light injected from the SiNx and TCO side reached 19.4%
and 18.1% (AM1.5G, 25°C), respectively. The performance and the quantum spectra of the cell are compared with a
normal bifacial HIT cell, and the result is constant with the simulation analysis. It could be concluded that the design
is a advantageous structure and the processing recipe is worked.

description: Sorghum is a C4 photosynthetic, drought resistant forage and grain plant species. Sorghum is cyanogenic in all tissues except for the mature seeds. The cyanogenesis pathway in sorghum produces the stable cyanogenic glucoside, dhurrin. The three biosynthetic genes in the cyanogenesis pathway are CYP79A1, CYP71E1 and UGT85B1. The first cytochrome P450, CYP79A1, is thought to be the rate limiting enzyme. Various sorghum lines were utilised for this study, with the mean hydrogen cyanide potential (HCNp) and coding sequence for CYP79A1 previously determined (O'Donnell et al., 2013). The coding sequences did not explain the observed difference in HCNp. Therefore, the 1.2Kb promoter region of CYP79A1 was sequenced and in silico analysis performed to look for a regulatory explanation to match the HCNp variances. Sequence variations were identified with potential cis-acting regulatory motifs exhibiting sequence alterations. When the cells of sorghum leaf tissue are masticated the dhurrin is hydrolysed by dhurrinase and hydrogen cyanide (HCN) is released. At low concentrations HCN can be metabolised safely by mammals but at higher concentrations it can cause toxic metabolic asphyxiation. The HCNp of sorghum is important in the cattle industry as forage sorghum is used as an alternate feed crop over summer. Many of the motifs identified in the CYP79A1 promoter region are potential light, circadian and/or temperature response elements. The regulation of dhurrin production has been investigated to determine if dhurrin is constitutively produced or whether the cyanogenesis pathway is under the control of a circadian or diurnal rhythm. Multiple experiments were conducted to compare dhurrin content under different light and temperature treatments in hydroponically grown forage sorghum and the results indicate that dhurrin is not under circadian or diurnal regulation. A gel mobility shift assay system was set up to look for DNA-binding proteins associating with the CYP79A1 promoter region. This method was successful in finding proteins that bound to fragments of the CYP79A1 promoter, which were then identified by isolating the proteins of interest and sending them for N-terminal sequencing at the Australian Proteome Analysis Facility (APAF). This resulted in the identification of a histone H1 protein and a histone H3 protein that strongly bound to a 62 base pair fragment of the CYP79A1 promoter, approximately 380 nucleotides upstream from the start codon. Histone H3 variants have been shown to be involved in transcriptional activation and the histones found could be part of a larger histone complex. This work provides a starting point for understanding the molecular mechanisms controlling the cyanogenesis biosynthesis pathway.

Heterojunction Solar Cells

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 441-446
description: After 10 years of operation of its Photovoltaic Technology Evaluation Centre PV-TEC Fraunhofer ISE
recently significantly expanded its research capabilities with the opening of a new pilot research facility for selective
contact solar cells – PV-TEC SELECT. PV-TEC SELECT aims to address major challenges on the way to
industrialize high efficiency solar cell concepts like Heterojunction (HJT) or TOPCon technology. In this context, the
paper introduces the new research facility with its unique equipment setup and process environment (Clean room
class 1000 on more than 800 m²). The development of a robust base line process allows Fraunhofer ISE to expand its
research offerings for PERC solar cells to next generation high efficiency cell concepts like HJT and TOPCon.

description: Second life silicon solar cells based on 100% recycled silicon have been recently produced at CEA-INES
in the frame of the CABRISS Project. A maximum efficiency of 18.1% has been reached (Al-BSF solar cells), with
Mono-like silicon substrate grown from recycled feedstock. During this first period of the project, several Silicon ingots
were produced using different conventional methods: Multi-Si standard casting method, Standard Cz-Si pulling and
also mono-Si seed-assisted casting method (Mono-like technology). To assess the photovoltaic potential of recycled
materials, we developed an overall material qualification protocol to evaluate the effect of the different solar cell
processing steps on the material quality. This study shows that all solar cells performances are in good agreement with
the data extracted from this protocol, especially with the bulk carrier lifetime determined after each technological step.
In addition this study brings new insights into the compatibility between novel Recycled Silicon feedstocks (Re-Si) and
the fabrication of standard solar cells. This is definitely an important step to improve the definition of the future Re-Si
feedstocks specifications and enhance the development of efficient recycling processes.

description: Interdigitated back contact (IBC) silicon solar cells featuring passivating contacts based on tunneling
oxides (SiOx) and n- and p-type polycrystalline silicon (poly-Si) thin films were fabricated with different rear side
configurations to show the impact of the recombination in the transition region between p-type and n-type poly-Si on
the performance of the solar cells. On the one hand a) p+ and n+ poly-Si regions were in direct contact to each other
(“no gap”) using a local overcompensation (counterdoping) as a self-aligning process and on the other hand b)
undoped (intrinsic) poly-Si remained between the p+ and n+ poly-Si regions (“gap”). These configurations were
investigated in terms of recombination characteristics by illumination- and injection-dependent quasi-steady state
photoluminescence (suns-PL) and were compared to solar cells that featured c) etched trenches separating the p+ and
n+ poly-Si regions (“trench”). While the latter configuration allowed for open-circuit voltages (Voc) of 720 mV, fill
factor (FF) of 79.6%, and short-circuit current (Jsc) of 41.3 mA/cm2, resulting in conversion efficiencies () of 23.7%,
solar cells without a trench showed a poor performance due to non-ideal recombination in the space charge regions
with high local ideality factors as well as recombination in shunted regions. Therefore, Voc of only 593 mV and FF of
only 61.3% were achieved for the “no gap” configuration whereas for the “gap” configuration higher Voc of 680 mV
but also low FF of 65.6% were obtained.

description: Magnetic dipole moment and mean-square charge radius of $^{199}$Pt ($I^π=$ 5/2$^-$) have been evaluated for the first time from the investigation of the hyperfine splitting of the $λ_1=$ 248.792 nm transition by in-gas-cell laser ionization spectroscopy. Neutron-rich nucleus $^{199}$Pt was produced by multi-nucleon transfer reaction at the KISS where the nuclear spectroscopy in the vicinity of $N=$ 126 is planed from the aspect of an astrophysical interest as well as the nuclear structure. Measured magnetic dipole moment $+$0.63(13)$μ_{\rm N}$ is consistent with the systematics of those of nuclei with $I^π=$ 5/2$^-$. The deformation parameter $|^{1/2}|$ evaluated from the isotope shift indicates the gradual shape change to spherical shape of platinum isotopes with increasing neutron number toward $N=$ 126.

description: Silicon is the dominant material used to make photovoltaic (PV) cells today and silicon wafers are sliced
from ingots by abrasive cutting processes. In this work, Wire Electric Discharge Machining (WEDM) is investigated
as a promising alternative for the conventional wafer-slicing methods. Through an experimental approach, the
behaviour of WEDM is characterised for silicon and compared with that for mild-steel. Parameteric analysis is done
with repsect to the available voltage and current levels and switching time intervals. In particular, the voltage-current
(V-I) characteristics, power consumption and material removal rate (MRR) for the two materials are compared.
Significant differences are observed in the I-V characteristics, which are discussed in this paper. The power consumed
in the case of silicon is observed to be 43% more than that for steel, for a certain set of parameters. To confirm the
suitablity of the method for PV application, the cut surfaces of silicon are subjected to Scanning Electron Microscopy
(SEM) and Inductively Coupled Atomic Emission Spectroscopy (ICPAES) for testing of surface roughness and
contamination.

description: Optical lattice clocks are the prospective devices that can probe many subtle physics including temporal variation of the fine structure constant ($α_e$). These studies necessitate high-precision measurements of atomic clock frequency ratios to unprecedented accuracy. In contrast to the earlier claimed highest sensitive coefficient ($K$) clock transition to $α_e$ in Yb [Phys. Rev. Lett. $\textbf{120}$, 173001 (2018)], we found the $4f^{14}6s6p\,(^3P_2) - 4f^{13}5d6s^{2}\,(^3P_2^*)$ transition of this atom can serve as the clock transition with the largest $K$ value (about $-$25(2)). Moreover, we demonstrate a scheme to attain simultaneous magic trapping conditions for this clock transition with the other two proposed clock transitions $4f^{14}6s^2\,(^1S_0) - 4f^{14}6s6p\,(^3P_2)$ and $4f^{14}6s^2\,(^1S_0) - 4f^{13}5d6s^{2}\,(^3P_2^*)$; also exhibiting large $K$ values. This magic condition can be realized by subjecting Yb atoms to a bias magnetic field at a particular polarization angle along the quantization axis in an experimental set up. Upon realization, it will serve as the most potential optical lattice clock to probe $α_e$ variation.

description: We critically discuss the measure of very short time intervals. By means of a Gedankenexperiment, we describe an ideal clock based on the occurrence of completely random events. Many previous thought experiments have suggested fundamental Planck-scale limits on measurements of distance and time. Here we present a new type of thought experiment, based on a different type of clock, that provide further support for the existence of such limits. We show that the minimum time interval $Δt$ that this clock can measure scales as the inverse of its size $Δr$. This implies an uncertainty relation between space and time: $Δr$ $Δt$ $> G \hbar / c^4$; where G, $\hbar$ and c are the gravitational constant, the reduced Planck constant, and the speed of light, respectively. We outline and briefly discuss the implications of this uncertainty conjecture.
