description: The scaling of the fundamental limits of the second hyperpolarizability is used to define the intrinsic second hyperpolarizability, which aids in identifying material classes with ultralarge nonlinear-optical response per unit of molecular size. The intrinsic nonlinear response is a size-independent metric that we apply to comparing classes of molecular homologues, which are made by adding repeat units to extend their lengths. Several new figures of merit are proposed that quantify not only the intrinsic nonlinear response, but also how the second hyperpolarizability increases with size within a molecular class. Scaling types can be classified into sub-scaling, nominal scaling that follows the theory of limits, and super-scaling behavior. Super-scaling homologues that have large intrinsic nonlinearity are the most promising because they efficiently take advantage of increased size. We apply our approach to data in the literature to identify the best super-scaling molecular paradigms and articulate the important underlying parameters.

description: Silicon is the dominant material in photovoltaic devices and with regard to the PV market growth, the
demand for solar grade silicon feedstock is expected to be high in the future. Although solar silicon is currently
produced through both chemical and metallurgical routes, the chemical route is still the main production method,
which is expensive and have environmental challenges. Acid leaching of silicon, which is a metallurgical refining
process is applied for silicon purification in the present research work. In this case, magnesium in different portions is
added to liquid silicon containing B, P, Fe, Al, and other trace impurities. The Si-Mg melts are solidified under a
controlled cooling rate and then they are treated by acid leaching through using dilute HCl solutions. The effect of
magnesium concentration on the segregation and removal of the impurities, in particular P and B, is studied by
electron microscopy and chemical analysis techniques. It is indicated that the process is effective for removing the
impurities, and the purification is depending on the amount of Mg added into the silicon.

description: In this work we show the results of development of recycling silicon scrap in an Electromagnetic
Casting Furnace. This EMC furnace has a number of advantages in terms of product costs: high growth rate,
eliminating the need to use expensive quartz crucibles and graphite components but it also has advantages in terms of
product quality due to the efficiency in carbon removal. Carbon and oxygen are measured along the column and in
several cross sections of the column showing that these impurities concentrate in the sidewalls of the ingots. The
efficiency in carbon removal is compared with some reported results on Directional Solidification furnaces. This
study confirms the promising use of EMC technology for recycling scrap material.

description: The developments set out on the fabrication route to produce upgraded metallurgical silicon (UMG-Si)
have led to an optimized material, whose results are promising when used to process standard Al-BSF solar cells.
Therefore, this UMG-Si material can be considered as a real and feasible alternative to produce industrial waferbased
silicon solar cells at lower cost and energy consumption. The objective of this study is to compare the
performance of different solar cells starting from UMG-Si material, in order to establish the factors influencing their
behavior. For this purpose, solar cells based on UMG-multicrystalline wafers with different resistivity values, height
in the ingot and compensation levels have been processed. At last, the analysis of the results obtained from the
characterization of the material properties (lifetime and resistivity) and from the complete characterization of the final
solar cells (EL, IV-Curve and SR) is presented.

description: The concept of "deep thermalization" has recently been introduced to characterize moments of an ensemble of pure states, resulting from projective measurements on a subsystem, which lie beyond the purview of conventional Eigenstate Thermalization Hypothesis (ETH). In this work, we study deep thermalization in systems with kinetic constraints, such as the quantum East and the PXP models, which have been known to weakly break ETH by the slow dynamics and high sensitivity to the initial conditions. We demonstrate a sharp contrast in deep thermalization between the first and higher moments in these models by studying quench dynamics from initial product states in the computational basis: while the first moment shows good agreement with ETH, higher moments deviate from the uniform Haar ensemble at infinite temperature. We show that such behavior is caused by an interplay of time-reversal symmetry and an operator that anticommutes with the Hamiltonian. We formulate sufficient conditions for violating deep thermalization, even for systems that are otherwise "thermal" in the ETH sense. By appropriately breaking these properties, we illustrate how the PXP model fully deep-thermalizes for all initial product states in the thermodynamic limit. Our results highlight the sensitivity of deep thermalization as a probe of physics beyond ETH in kinetically-constrained systems.

description: In this paper, we present n-type rear junction (RJ) PERT (Passivated Emitter Rear Totally-diffused) solar cell with the process improvement of Laser Contact Opening (LCO) process and rear pattern opened by laser. In detail, effect of laser process parameter such as laser power and pulse duration was evaluated in terms of impact on the cell efficiency and opening shape. Also LCO pattern such as line, dash and dot was optimized to reduce rear electrode contact area to minimize the recombination characteristics of n-RJ-PERT cells. Through this, we achieved 21.77% efficiency, and 686 mV open-circuit voltage(in-house measured) of n-RJ-PERT solar cell with plated Ni/Ag front contacts, Al2O3 rear passivation, and screen-printed local Al emitter on 110μm-thickness 6-inch n-type Czochralski (Cz) single crystalline.

description: Vocational education enhances an individual’s chances of finding gainful employment and equips individuals with knowledge and technical skills as well as behavioural competencies needed to increase the chances of gaining and remaining in employment. Despite all these qualities, vocational education has continued to witness low engagement in Plateau state, especially in Jos-North which has witnessed bursts of conflicts since 2001. With a 74.1% rate of poverty resulting in a large population of unemployed youth from poor background, Jos-North being the largest local government, records the largest percentage of unemployed youths. One of the problems identified is that parents are not enrolling their children in vocational education, evidenced by the low enrolment rate into vocational education which was less than 3% as at 2009/2010 and as at 2016/2017, out of the expected 800,000 enrolments into vocational and technical colleges, only 74,299 students were enrolled.Guided by five objectives, this research set out to explore the factors which influence the decisions of parents towards vocational education; the factors which influence the decisions of parents more than others, parent’s preferences for vocational or general education, and the circumstances under which parents would change their preference.The research adopted the interpretivist philosophy and a mixed method approach. 400 semi-structured questionnaires were distributed using stratified and snowballing techniques. Using saturation method, 41 responses were selected for thematic content analysis and discussions. The Social Ecological Model was used as a key theoretical position to build towards the rationale and purpose of the study.Result shows that the decisions of parents in Jos-North are influenced by several factors which includes socio-cultural, socio-economic, socio-political, and environmental factors. Results also reveal that some factors influence the decisions of parents more than others and that more parents are willing to change their decisions if some factors change.

title: Patients or Perpetrators? An Exploration of Psychological Trauma in Incarcerated Gang and Non-Gang Males
Creators: name: Beresford, Hayley
Publisher: name: University of Kent
Year: 2023

description: Gangs and gang violence are a serious problem affecting the health and wealth of many communities across the globe. Violence is central to the gang's identity and operation; as such, the majority of gang research has focused on understanding gang members as perpetrators of violence using traditional socio-criminological theories that support a criminal justice solution. To date, little research has focussed on the psychological causes or effects of violence in this population. This is surprising giving that trauma exposure and traumatic sequalae, such as PTSD, are known risk factors for criminal justice involvement, and that gang members, by virtue of the activities they participate in, are likely to be exposed to potentially traumatising events. Building on the psycho-traumatological study of juvenile delinquents and the growing discipline of gang psychology, this thesis marks a small contribution towards a systematic programme of research dedicated to mapping, and intervening to change, the trauma pathways of gang-involved males. Across six chapters, comprising theory, empirical works, and critical commentary this thesis found that; 1) there is a significant gap in the extant literature that illuminates the need for more trauma-centric gang studies; 2) existing developmental models of trauma can be re-purposed and adapted to explain how PTSD-induced deficits in biological, emotional, cognitive, and interpersonal functioning, alongside harmful group processes inherent in the gang, contribute to more severe and enduring trauma trajectories for gang members compared to their non-gancounterparts; 3) results from the quantitative study showed that gang members were more likely to experience weapons-related trauma, including exposure to toxic substances, as well greater levels of group identification, group pressure, pluralistic ignorance, moradisengagement, individual and group delinquency, and were more likely to exhibit antisocial and paranoid personality traits. The qualitative findings speak to the xpervasiveness and disruptiveness of trauma in the lives' of young incarcerated males, irrespective of membership status. The implications of this thesis speak to the propogration of a new subdiscipline of psychological research-Gang Psychotraumatology; the creation of trauma-informed place-based interventions that consider the multiple dichotomies of gang members as individuals and group agents, victims and perpetrators; and policies that support the humanisation and rehabilitation of gang members.

description: In this work, we adopt the one-boson-exchange model to study the $Y_cK^{(*)} (Y_c=Λ_c, Σ_c)$ interactions. After considering both of the $S-D$ wave mixing effects and the coupled channel effects, we can predict several possible open-charm molecular pentaquarks, i.e., the single $Σ_cK^*$ molecular states with $I(J^P)=1/2(1/2^-)$, $1/2(3/2^-)$ and $3/2(1/2^-)$, the coupled $Λ_cK^*/Σ_cK^*$ molecular states with $1/2(1/2^-)$ and $1/2(3/2^-)$, and the coupled $Σ_cK/Λ_cK^*/Σ_cK^*$ molecular state with $1/2(1/2^-)$. Meanwhile, we extend our study to the $Y_c\bar{K}^{(*)}$ interactions, our results suggest the $Σ_c\bar{K}$ system with $I(J^P)=1/2(1/2^-)$, the $Σ_c\bar{K}^*$ systems with $1/2(1/2^-)$, $1/2(3/2^-)$, and $3/2(3/2^-)$, the coupled $Λ_c\bar{K}^*/Σ_c\bar K^*$ system with $1/2(1/2^-)$, and the $Σ_c\bar{K}/Λ_c\bar{K}^*/Σ_c\bar K^*$ system with $1/2(1/2^-)$ can be the prime molecular candidates.

description: There are 15 cataclysmic variables (CVs) observed in the first two campaigns of the K2 mission. In this paper, the eight CVs showing distinct features are analyzed in detail. Among these eight, modulations during quiescence are evident at the known orbital periods in the SU UMa stars QZ Vir and RZ Leo, and at our newly determined orbital periods of 1RXS J0632+2536 and WD 1144+011. The periodogram analysis for the quiescent light curve of QZ Vir reveals multi-period modulations and the coexistence of orbital and superhump periods. The phased orbital light curves for the other 3 CVs in quiescence display wide (about half cycle) and shallow (< 0.5 mag) eclipse features. Besides these modulations, their quiescent light curves reveal several transient events: a sudden decrease of system light in 1RXS J0632+2536, a low level flare-like event in QZ Vir, a short brightening event in RZ Leo and a temporary disappearance of the orbital modulation in WD 1144+011. The two known dwarf novae UV Gem and TW Vir and the CVs USNO-B1.01144-00115322 and CSS130516:111236.7+002807 show outbursts, including 1 complete and 3 incomplete normal outbursts and 2 complete superoutbursts. An incomplete but typical normal outburst confirms the dwarf nova identification of the USNO-B1.01144-00115322. The one complete normal outburst in UV Gem possibly provides the orbital period, since its modulations are shorter than the previously observed superhump period. The superoutbursts of TW Vir and CSS130516:111236.7+002807, along with their corresponding superhump periods, indicate that both objects are SU UMa stars. The derived superhump period of CSS130516:111236.7+002807 is 1.44 hr, implying that this new SU UMa star is close to the period minimum.

description: Inline photoluminescence (PL) imaging has been applied to identify impurity-decorated dislocation
clusters and grain boundaries in as-cut wafers. The ratio of impuritiy-decorated dislocation clusters area and grain
boundaries area to the total area in wafer can be calculated separately by software. Ten wafers are selected from
bottom and top region of a central block with a defect area ratio of 7.5% to fabricate solar cells respectively. The
result shows that for the samples with main grain boundaries defect, there is a 0.11% absolute efficiency higher than
that of samples with dislocation clusters defect. It can be concluded that grain boundaries contribute a relatively less
negative effect on the performance of solar cells after the gettering process. Meanwhile, impurities prefer to interact
with dislocation clusters in top area of ingot.

On the formation of compact planetary systems via concurrent core accretion and migration

description: We present the results of planet formation N-body simulations based on a comprehensive physical model that includes planetary mass growth through mutual embryo collisions and planetesimal/boulder accretion, viscous disc evolution, planetary migration and gas accretion onto planetary cores. The main aim of this study is to determine which set of model parameters leads to the formation of planetary systems that are similar to the compact low mass multi-planet systems that have been discovered by radial velocity surveys and the Kepler mission. We vary the initial disc mass, solids-to-gas ratio and the sizes of the boulders/planetesimals, and for a restricted volume of the parameter space we find that compact systems containing terrestrial planets, super-Earths and Neptune-like bodies arise as natural outcomes of the simulations. Disc models with low values of the solids-to-gas ratio can only form short-period super-Earths and Neptunes when small planetesimals/boulders provide the main source of accretion, since the mobility of these bodies is required to overcome the local isolation masses for growing embryos. The existence of short-period super-Earths around low metallicity stars provides strong evidence that small, mobile bodies (planetesimals, boulders or pebbles) played a central role in the formation of the observed planets.

description: A novel coronavirus (CoV), Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), emerged in late 2019 in Wuhan, China and has since spread as a global pandemic. Safe and effective vaccines are urgently needed to reduce the significant morbidity and mortality of Coronavirus Disease 2019 (COVID-19) and ease the major economic impact. There has been an unprecedented rapid response by vaccine developers with >140 vaccine candidates in preclinical development and >20 having reached clinical trials. However, a major challenge during rapid development is to avoid safety issues both by thoughtful vaccine design and by thorough safety evaluation in a timely manner. This SO2 D2.4 deliverable was meant to summarize recommendations for vaccine safety data collection, CRF, presentation and analysis for clinical trials of CEPI funded vaccine candidates targeting COVID-19. SPEAC has responded to this challenge by summarizing recommendations by the Brighton Collaboration and SPEAC project for vaccine safety data collection, CRF, presentation and analysis for clinical trials of CEPI funded vaccine candidates targeting COVID-19 with sample CRF presented in Appendix 1. In response to a request by CEPI to provide comments to the 19April version of the WHO Solidarity Protocol, SPEAC outlined the safety evaluations that should be included for trials of COVID-19 vaccine candidates with input from some Meta-DSMB members. As an example, we provided a memory aid for collection of solicited local and systemic reactions following immunization included as Appendix 2. A guide for presentation and analysis of these solicited local and systemic reaction data is included as Appendix 3 using the Brighton Collaboration case definitions as a reference where available. We also reviewed the information about enhanced disease following immunization with prior coronavirus vaccine candidates for SARS and MERS, establishing an initial literature search to gather the available information on this topic and then with the support of CEPI (Appendix 4), and organized a virtual 2-day consensus meeting on March 12 and 13, 2020 to review the preclinical data with a panel of experts. This meeting led to consensus recommendations for developers with the input of regulators attending the meeting that has been published and is included as Appendix 5.

description: In this paper, we report the results of an upgrade from an Al-BSF solar cell line to a PERC (passivated
emitter and rear cell) solar cell line, based on p-type mono-crystalline silicon (mono c-Si) material. For the rear side
Al2O3 passivation, an InPassion ALD system of SoLayTec was used. The PERC solar cell optimization has been done in
three main steps: first we optimized the rear side SiNx capping layer, leading to a solar cell efficiency increase of
+0.4%abs with respect to the mono c-Si Al-BSF solar cell baseline. Secondly, we optimized the rear side polishing depth
from 1-2 μm to 3-4 μm, which results in a solar cell efficiency gain of +0.5%abs with respect to the standard Al-BSF solar
cell baseline. For the third optimization, the emitter sheet resistance has been increased from (78±3) Ω/sq to (90±5) Ω/sq,
resulting in a solar cell efficiency of (20.44±0.17)% and a gain of >+0.8%abs with respect to the Al-BSF baseline. After
several repeat runs, where the number of PERC solar cells has been increased to >1000 wafers per run with >1.0%abs
solar cell efficiency gain, >50000 PERC solar cells have been processed over two days with a stable solar cell efficiency
of (20.5±0.3)% and best cell with efficiency of 21.1%. The reliability of the InPassion ALD system has been improved
by decreasing the breakage rate from 0.19%abs to 0.05%abs. Finally, it has been proven that with the latest configuration of
the system, the breakage rate can be reduced even more to ≤0.05%abs.

description: Planetesimals in gaseous protoplanetary disks may grow by collecting dust particles. Hydrodynamical studies show that small particles generally avoid collisions with the planetesimals because they are entrained by the flow around them. This occurs when $St$, the Stokes number, defined as the ratio of the dust stopping time to the planetesimal crossing time, becomes much smaller than unity. However, these studies have been limited to the laminar case, whereas these disks are believed to be turbulent. We want to estimate the influence of gas turbulence on the dust-planetesimal collision rate and on the impact speeds. We used three-dimensional direct numerical simulations of a fixed sphere (planetesimal) facing a laminar and turbulent flow seeded with small inertial particles (dust) subject to a Stokes drag. A no-slip boundary condition on the planetesimal surface is modeled via a penalty method. We find that turbulence can significantly increase the collision rate of dust particles with planetesimals. For a high turbulence case (when the amplitude of turbulent fluctuations is similar to the headwind velocity), we find that the collision probability remains equal to the geometrical rate or even higher for $St\geq 0.1$, i.e., for dust sizes an order of magnitude smaller than in the laminar case. We derive expressions to calculate impact probabilities as a function of dust and planetesimal size and turbulent intensity.

description: I present the calculation of the $π^+γ^\star\toπ^+π^0$ transition amplitude from quantum chromodynamics performed by the Hadron Spectrum Collaboration. The amplitude is determined for a range of values of the photon virtuality and the final state energy. One observes a clear dynamical enhancement due to the presence of the $ρ$ resonance. By fitting the transition amplitude and analytically continuing it onto the $ρ$-pole, the $ρ\toπγ^\star$ form factor is obtained. This exploratory calculation, performed using lattice quantum chromodynamics, constitutes the very first determination of an electroweak decay of a hadronic resonance directly from the fundamental theory of quarks and gluons. In this talk, I highlight some of the necessary steps that made this calculation possible, placing emphasis on recently developed formalism. Finally, I discuss the status and outlook of the field for the study of $Nγ^\star\to N^\star\to Nπ$ transitions.

description: The synthesis and detailed characterization of the noncentrosymmetric superconductor Re$_{6}$Hf using powder x-ray diffraction (XRD), magnetization, transport and thermodynamic measurements are reported. XRD confirms the crystal structure of Re$_{6}$Hf to be cubic noncentrosymmetric $α$-\textit{Mn} with a lattice parameter a = 9.6850(3)\textÅ. Resistivity, DC and AC magnetization confirms the bulk superconducting transition T$_{c}^{onset} \sim $ ~ 5.96 K. The lower critical field H$_{C1}(0)\approx$ 5.6 mT and upper critical H$_{C2}(0)$ was found to be around 12.2 T which is greater than the Pauli limiting field, indicating unconventional behavior in Re$_{6}$Hf and leads to the possibility of triplet pairing. A sharp discontinuity in the specific heat data was observed around T$_{c}$ indicating bulk superconductivity, and the normalized specific heat jump is $ΔC_{el}$/$γ_{n}$T$_{c}$ = 1.53 which is in close agreement with BCS value. Superconducting electronic specific heat data is fitted reasonably well for an exponential relation with Sommerfeld coefficient ($γ$) showing a linear relation with magnetic field suggesting that in Re$_{6}$Hf dominant pairing channel is s-wave with isotropic superconducting gap parameter without nodes.

description: In recent years, scientific CMOS (sCMOS) sensors have been vigorously developed and have outperformed CCDs in several aspects: higher readout frame rate, higher radiation tolerance, and higher working temperature. For silicon image sensors, image lag will occur when the charges of an event are not fully transferred inside pixels. It can degrade the image quality for optical imaging, and deteriorate the energy resolution for X-ray spectroscopy. In this work, the image lag of a sCMOS sensor is studied. To measure the image lag under low-light illumination, we constructed a new method to extract the image lag from X-ray photons. The image lag of a customized X-ray sCMOS sensor GSENSE1516BSI is measured, and its influence on X-ray performance is evaluated. The result shows that the image lag of this sensor exists only in the immediately subsequent frame and is always less than 0.05% for different incident photon energies and under different experimental conditions. The residual charge is smaller than 0.5 e- with the highest incident photon charge around 8 ke-. Compared to the readout noise level around 3 e-, the image lag of this sensor is too small to have a significant impact on the imaging quality and the energy resolution. The image lag shows a positive correlation with the incident photon energy and a negative correlation with the temperature. However, it has no dependence on the gain setting and the integration time. These relations can be explained qualitatively by the non-ideal potential structure inside the pixels. This method can also be applied to the study of image lag for other kinds of imaging sensors.

description: The metastable helium triplet in the near-infrared (10833Å) is among the most important probes of exoplanet atmospheres. It can trace their extended outer layers and constrain mass-loss. We use the near-infrared high-resolution spectropolarimeter SPIRou on the CFHT to search for the spectrally resolved helium triplet in the atmospheres of eleven exoplanets, ranging from warm mini-Neptunes to hot Jupiters and orbiting G, K, and M dwarfs. Observations were obtained as part of the SPIRou Legacy Survey and complementary open-time programs. We apply a homogeneous data reduction to all datasets and set constraints on the presence of metastable helium, despite the presence of systematics in the data. We confirm published detections for HAT-P-11b, HD189733b, and WASP-69b and set upper limits for the other planets. We apply the p-winds open source code to set upper limits on the mass-loss rate for the non-detections and to constrain the thermosphere temperature, mass-loss rate, line-of-sight velocity, and the altitude of the thermosphere for the detections. We confirm that the presence of metastable helium correlates with the stellar mass and the XUV flux received by the planets. We investigated the correlation between the mass-loss rate and the presence of metastable helium, but it remains difficult to draw definitive conclusions. Finally, some of our results are in contradiction with previous results in the literature, therefore we stress the importance of repeatable, homogeneous, and larger-scale analyses of the helium triplet to obtain robust statistics, study temporal variability, and better understand how the helium triplet can be used to explore the evolution of exoplanets.

description: One common requirement for all frontside contacted cells is to utilize fine finger lines with good conductivity. An established technique already proven in mass production is Fine Line Double Printing, able to deliver finger widths of 40-45 μm and an Aspect Ratio of 0.5. In this paper an evolution of this approach is described, where: 1) busbars are printed separately from fingers and 2) fingers are printed twice with the same screen. This patented concept allows for increased printing consistency and a greatly simplified process in terms of screens and tool.
Photodisintegration cross section of $^9$Be up to 16 MeV in the $α$ + $α$ + n three-body model

description: The photodisintegration of $^9$Be in the energy region lower than $E_γ= 16$ MeV is investigated by using the $α$~+~$α$~+~$n$ three-body model and the complex scaling method. The cross section exhibits two aspects in the different two energy regions. In the low energy region up to $E_γ= 6$ MeV, the cross section is explained by the transition strengths into the excited resonant states of $^9$Be, while the dipole transition into the non-resonant continuum states of $^8$Be(2$^+$)~+~$n$ dominates the cross section in the energy region of $6 \le E_γ\le 16$ MeV. Furthermore, it is shown that the dipole strength at $E_γ\sim 8$ MeV is understood to be caused by the single-neutron excitation from the $^8$Be(2$^+$)~$\otimes$~$νp_{3/2}$ configuration in the ground state.

An alternative order-parameter for non-equilibrium generalized spin models on honeycomb lattices

description: An alternative definition for the order-parameter is proposed, for a family of non-equilibrium spin models with up-down symmetry on honeycomb lattices, and which depends on two parameters. In contrast to the usual definition, our proposal takes into account that each site of the lattice can be associated with a local temperature which depends on the local environment of each site. Using the generalised voter motel as a test case, we analyse the phase diagram and the critical exponents in the stationary state and compare the results of the standard order-parameter with the ones following from our new proposal, on the honeycomb lattice. The stationary phase transition is in the Ising universality class. Finite-size corrections are also studied and the Wegner exponent is estimated as $ω=1.06(9)$.

description: A new and simple patterning technique has been developed to fabricate local back contacts (LBCs) of rear-surface-passivated Si solar cells. Randomly hole-patterned polystyrene (PS) films were fabricated on p-type Si wafers by spin-coating of PS films followed by soaking in an acetone (ACE) solution. The hole-patterned PS films were then served as wet-etch masks of SiO2/SiNx stacked passivation layers, and LBCs were formed by wet-etch process followed by screen-printing of Al paste. The hole area fraction on the PS film can be adjusted by change of ACE soaking time. Passivated emitter and rear cells (PERCs) have been demonstrated using this patterning process.
Photo-induced gap closure in an excitonic insulator

description: We study the dynamical phase transition out of an excitonic insulator phase after photo-excitation using a time-dependent extension of the selfconsistent GW method. We connect the evolution of the photoemission spectra to the dynamics of the excitonic order parameter and identify two dynamical phase transition points marked by a slowdown in the relaxation: one critical point is connected with the trapping in a nonthermal state with reduced exciton density and the second corresponds to the thermal phase transition. The transfer of kinetic energy from the photoexcited carriers to the exciton condensate is shown to be the main mechanism for the gap melting. We analyze the low energy dynamics of screening, which strongly depends on the presence of the excitonic gap, and argue that it is difficult to interpret the static component of the screened interaction as the effective interaction of some low energy model. Instead we propose a phenomenological measure for the effective interaction which indicates that screening has minor effects on the low energy dynamics.

description: We investigate the dynamical properties of low frequency quasi-periodic oscillations (QPOs) observed from the black hole X-ray binary MAXI J1820+070 during the early part of its 2018 outburst, when the system was in a bright hard state. To this aim, we use a series of observations from the Hard X-ray Modulation Telescope Insight-HXMT, and apply a wavelet decomposition (weighted wavelet Z-transforms) to the X-ray light-curve. We find that the QPO phenomenon is intermittent within each individual observation, with some sub-intervals where the oscillation is strongly detected (high root-mean-square amplitude) and others where it is weak or absent. The average life time of individual QPO segments is ~ 5 oscillation cycles, with a 3 sigma tail up to ~ 20 cycles. There is no substantial difference between the energy spectra during intervals with strong and weak/absent QPOs. We discuss two possible reasons for the intermittent QPO strength, within the precessing jet model previously proposed for MAXI J1820+070. In the rigid precession model, intermittent QPOs are predicted to occur with a coherence Q ~ a few when the disk alignment time-scale is only a few times the precession time-scale. Alternatively, we suggest that changes in oscillation amplitude can be caused by changes in the jet speed. We discuss a possible reason for the intermittent QPO strength, within the precessing jet model previously proposed for MAXI J1820+070: we suggest that changes in oscillation amplitude are caused by changes in the jet speed. We argue that a misaligned, precessing jet scenario is also consistent with other recent observational findings that suggest an oscillation of the Compton reflection component in phase with the QPOs.
