description: Despite the relevant fire risk to which Italy is subject from the north to the south, very few analyses focus on this topic. This article investigates the causes of forest fires frequency and intensity in Italy during the first decade of the twentyfirst century. The dynamical aspects of fire danger are explored through the use of panel data techniques, which fully capture the impacts on forest fires regarding changes in both socioeconomic and climatic conditions. Italy is treated as a unique region in an initial model specification, and is then split into 3 geographical areas (north, center, and south) to capture locally specific aspects. Two different dependent variables are alternatively employed and a number of ad hoc tests are performed to corroborate the robustness of our estimates. The results highlight the importance of considering the fire situation separately for the northern, central, and southern parts of Italy. While the presence of railway networks positively affects fire risk, the impact of livestock depends on its specific composition. Favorable effects in fire reduction are represented by the increase in education levels (north and center) and touristic flows (north and south), and by the containment of illegal activities (south). Weather patterns appear to be important

determinants throughout the Italian peninsula.

description: Größen begegnen uns überall im Alltag: Wir behalten morgens die Uhrzeit im Blick, damit wir nicht zu spät zur Arbeit oder zur Schule aufbrechen (Größenbereich Zeit), beim Kochen orientieren wir uns an Gewichtsangaben der einzelnen Zutaten (Größenbereich Gewicht) und beim Leichtathletikturnier werden beispielsweise Längen beim Weitwurf oder Weitsprung nachgemessen (Größenbereich Länge). Dem Größenbereich Länge kommt insofern eine besondere Bedeutung zu, als dass dieser nicht nur eine Grundlage für das Zahlverständnis und Zahlbeziehungen, sondern auch für die Skalierung von Messwerkzeugen für andere Größenbereiche darstellt (beispielsweise beim Thermometer) (Franke & Ruwisch, 2010). Dementsprechend ist es ein zentrales Ziel des Mathematikunterrichts, dass Kinder am Ende der Grundschulzeit über verschiedene Größenvorstellungen (auch im Bereich Länge) verfügen (KMK, 2004). Welche Facetten das Konstrukt der Größenvorstellungen umfasst, ist jedoch nicht immer eindeutig und – insbesondere empirisch – noch weitestgehend ungeklärt (Hoth & Nührenbörger, 2021).

description: There are now five angular momentum relations or sum rules in the literature: the Jaffe, Manohar relation for a longitudinally polarized nucleon, and the Bakker, Leader, Trueman result for the case of transverse polarization; the Ji relation for longitudinal polarization, and the Leader result for transverse polarization, both involving generalized parton distributions; and a new sum rule due to Ji, Xiong and Yuan dealing with the transverse component of the Pauli-Lubanski vector. I discuss these various relations and examine their precise interpretation in the light of the so-called "angular momentum controversy". In particular, I show that the claim of Ji, Xiong and Yuan that their Pauli-Lubanski relation is frame or energy independent is incorrect, and that they have missed an energy dependent term in their expression.

description: We present a search for the standard model Higgs boson in 9.5 fb-1 of ppbar collisions at sqrt(s) = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. The final state considered contains a pair of b jets and is characterized by an imbalance in transverse energy, as expected from ppbar->ZH->vvbb production. The search is also sensitive to the WH->lvbb channel when the charged lepton is not identified. The data are found to be in good agreement with the expected background. For a Higgs boson mass of 125 GeV, we set a limit at the 95% C.L. on the cross section sigma(ppbar->[Z/W]H), assuming standard model branching fractions, that is a factor of 4.3 times larger than the theoretical standard model value, while the expected factor is 3.9. The search is also used to measure a combined WZ and ZZ production cross section that is a factor of 0.94 +/- 0.31(stat) +/- 0.34(syst) times the standard model prediction of 4.4 pb, with an observed significance of 2.0 standard deviations.

A class of nonergodic interacting particle systems with unique invariant measure

Year: 2012
Subjects: subject: Probability (math.PR)

description: We consider a class of discrete $q$-state spin models defined in terms of a translation-invariant quasilocal specification with discrete clock-rotation invariance which have extremal Gibbs measures $μ'_φ$ labeled by the uncountably many values of $φ$ in the one-dimensional sphere (introduced by van Enter, Opoku, Külske [J. Phys. A 44 (2011) 475002, 11]). In the present paper we construct an associated Markov jump process with quasilocal rates whose semigroup $(S_t)_{t\geq0}$ acts by a continuous rotation $S_t(μ'_φ)=μ'_{φ+t}$. As a consequence our construction provides examples of interacting particle systems with unique translation-invariant invariant measure, which is not long-time limit of all starting measures, answering an old question (compare Liggett [Interacting Particle Systems (1985) Springer], question four, Chapter one). The construction of this particle system is inspired by recent conjectures of Maes and Shlosman about the intermediate temperature regime of the nearest-neighbor clock model. We define our generator of the interacting particle system as a (noncommuting) sum of the rotation part and a Glauber part. Technically the paper rests on the control of the spread of weak nonlocalities and relative entropy-methods, both in equilibrium and dynamically, based on Dobrushin-uniqueness bounds for conditional measures.

description: The temperature dependence of the complex optical properties of the three-dimensional topological insulator Bi2Te2Se is reported for light polarized in the a-b planes at ambient pressure, as well as the effects of pressure at room temperature. This material displays a semiconducting character with a bulk optical gap of 300 meV at 295 K. In addition to the two expected infrared-active vibrations observed in the planes, there is additional fine structure that is attributed to either the removal of degeneracy or the activation of Raman modes due to disorder. A strong impurity band located at 200 cm^{-1} is also observed. At and just above the optical gap, several interband absorptions are found to show a strong temperature and pressure dependence. As the temperature is lowered these features increase in strength and harden. The application of pressure leads to a very abrupt closing of the gap above 8 GPa, and strongly modifies the interband absorptions in the mid-infrared spectral range. While ab initio calculations fail to predict the collapse of the gap, they do successfully describe the size of the band gap at ambient pressure, and the magnitude and shape of the optical conductivity.

description: The agricultural sector is increasingly dependent upon the use of plastic products to enhance productivity. In addition to many incidental inputs, plastic fragments are progressively accumulating in soil following the degradation of plastic products. Microplastics (MPs, <5 mm) and nanoplastics (NPs, <1 µm) in agricultural soils have caused substantial concerns recently. The insidious interactions between plants, soil, and MPs/NPs in the agricultural environment could affect soil health, crop productivity, and threaten food safety and human health. Importantly, finer NPs can be taken up by plants, induce oxidative stress and negatively affect plant growth. Even though interactions of MPs/NPs with plants in the plant-soil nexus have been reported, a comprehensive review of the state of knowledge is lacking, which hinders continued progress in this emerging field. This review aims to fill the gap by extensively summarizing MPs/NPs sources in agriculture, techniques to investigate, impact on soil properties and accumulation in the plants. The synergistic effect of organic and inorganic co-contaminants and MPs/NPs are highlighted due to the widespread presence of these chemicals in agricultural soils. This review also presented possible mechanisms of MPs/NPs phytotoxicity. Although new information is emerging there is a paucity of data on the fate and impact of MPs/NPs in the plant-soil nexus. More efforts are needed to elucidate the fate and impact of MPs/NPs in agricultural soils to gain a deeper understanding of their health and safety implications.

description: Il contributo analizza l'approccio di comunicazione scientifica adottato dal Consorzio REMAP (reusable mask patterning) finanziato dal programma PathFinder Open dello European Innovation Concil e pubblicato come deliverable D4.4.

L'approccio parte dalla formazione dei membri del Consorzio volta a migliorarne la comunicazione verso un pubblico diversificato attraverso la creazione di strumenti inclusivi. La strategia è stata applicata al Festival della Scienza di Genova (Autunno 2023), dove sono state presentate le basi etiche e scientifiche del paradigma di microfabbricazione sviluppato da REMAP, anche mediante narrazioni, dimostrazioni pratiche, e questionari interattivi, mirati a rendere accessibili concetti complessi e stimolare curiosità, conoscenza e libera espressione.

Dal questionario, è emerso che circa l’80% del pubblico si autodefinisce di età inferiore ai 38 anni, il 70% di genere femminile e il 30% maschile. Più del 50% possiede il diploma come titolo più alto, mentre circa il 20% ha una laurea magistrale. Oltre il 90% si è dichiarato interessato ad approfondire le discipline STEM, e la totalità ha concordato sull'importanza socioeconomica e ambientale della tematica affrontata. Circa l'88% ritiene che i risultati avranno un impatto indipendente dal genere.

REMAP sostiene l'inclusione di genere nei settori scientifici e tecnologici adottando una comunicazione imparziale che normalizzi il ruolo delle donne. Questa esperienza contribuisce al dibattito sulla divulgazione scientifica e dell’innovazione come strumento per accompagnare il pubblico nella costruzione di un’identità disciplinare, contribuendo ad analizzare il divario di genere nelle scelte tecniche e scientifiche.

description: In this article we present high-resolution angle-resolved photoemission (ARPES) spectra of the heavy-fermion superconductor URu$_2$Si$_2$. Measurements as a function of both excitation energy and temperature allow us to disentangle a variety of spectral features, revealing the evolution of the low energy electronic structure across the hidden order transition. Already above the hidden order transition our measurements reveal the existence of weakly dispersive states below the Fermi level that exhibit a large scattering rate. Upon entering the hidden order phase, these states transform into a coherent heavy fermion liquid that hybridizes with the conduction bands.

description: It has recently been suggested that the competition for a finite pool of microRNAs (miRNA) gives rise to effective interactions among their common targets (competing endogenous RNAs or ceRNAs) that could prove to be crucial for post-transcriptional regulation (PTR). We have studied a minimal model of PTR where the emergence and the nature of such interactions can be characterized in detail at steady state. Sensitivity analysis shows that binding free energies and repression mechanisms are the key ingredients for the cross-talk between ceRNAs to arise. Interactions emerge in specific ranges of repression values, can be symmetrical (one ceRNA influences another and vice-versa) or asymmetrical (one ceRNA influences another but not the reverse) and may be highly selective, while possibly limited by noise. In addition, we show that non-trivial correlations among ceRNAs can emerge in experimental readouts due to transcriptional fluctuations even in absence of miRNA-mediated cross-talk.

description: Partners of patients with stroke are at high risk for burden, anxiety and depressive symptoms. Previous studies have reported contradictory results and did not investigate these three courses simultaneously. In this study we comprehensively studied the courses and predictors of burden, anxiety and depressive symptoms in partners of patients with stroke during the first two years after stroke. They were analyzed as outcomes as well as predictors for each other. Six general hospitals recruited 215 patients with stroke and their partners for a longitudinal cohort study. Mixed model analyses were performed for burden (CSI), anxiety (HADS-A) and depressive symptoms (HADS-D) as time-varying outcome variables, measured at four time points during two years after stroke. Burden and depressive symptoms did not significantly change over time, whereas anxiety symptoms initially decreased followed by an increase. Higher burden was predicted by partners’ younger age, higher education, more symptoms of anxiety and depression, and by patients’ greater stroke severity, lower cognitive functioning and more symptoms of anxiety and depression. More anxiety symptoms were predicted by higher burden, more depressive symptoms, and lower self-efficacy of the partner. More depressive symptoms were predicted by older age, higher burden, more symptoms of anxiety, less proactive coping strategies of the partner, and more depressive symptoms of the patients. Burden, anxiety and depressive symptoms are interrelated and become chronic in partners of patients with stroke. It is important to screen partners early after stroke to identify partners who are at risk for negative outcomes.

description: In this paper, we compare dispersions of a scalar field in Euclidean quantum gravity with stochastic inflation. We use Einstein gravity and a minimally coupled scalar field with a quadratic potential. We restrict our attention to small mass and small field cases. In the Euclidean approach, we introduce the ground state wave function which is approximated by instantons. We used a numerical technique to find instantons that satisfy classicality. In the stochastic approach, we introduce the probability distribution of Hubble patches that can be approximated by locally homogeneous universes down to a smoothing scale. We assume that the ground state wave function should correspond to the stationary state of the probability distribution of the stochastic universe. By comparing the dispersion of both approaches, we conclude three main results. (1) For a statistical distribution with a certain value, we can find a corresponding instanton in the Euclidean side, and it should be a complex-valued instanton. (2) The size of the universe of the Euclidean approach corresponds to the smoothing scale of the stochastic side; the universe is homogeneous up to the Euclidean instanton. (3) In addition, as the mass increases up to a critical value, both approaches break at the same time. Hence, generation of classical inhomogeneity in the stochastic approach and the instability of classicality in the Euclidean approach are related.

description: TEMPO, selected by NASA as the first Earth Venture Instrument, will measure atmospheric pollution for greater North America from space using ultraviolet and visible spectroscopy. TEMPO measures from Mexico City to the Canadian oil sands, and from the Atlantic to the Pacific, hourly and at high spatial resolution. TEMPO provides a tropospheric measurement suite that includes the key elements of tropospheric air pollution chemistry. Measurements are from geostationary (GEO) orbit, to capture the inherent high variability in the diurnal cycle of emissions and chemistry. The small product spatial footprint resolves pollution sources at sub-urban scale. Together, this temporal and spatial resolution improves emission inventories, monitors population exposure, and enables effective emission-control strategies.

TEMPO takes advantage of a GEO host spacecraft to provide a modest-cost mission that measures the spectra required to retrieve O3, NO2, SO2, H2CO, C2H2O2, H2O, aerosols, cloud parameters, and UVB radiation. TEMPO thus measures the major elements, directly or by proxy, in the tropospheric O3 chemistry cycle. Multi-spectral observations provide sensitivity to O3 in the lowermost troposphere, reducing uncertainty in air quality predictions by 50 %. TEMPO quantifies and tracks the evolution of aerosol loading. It provides near-real-time air quality products that will be made widely, publicly available.

TEMPO makes the first tropospheric trace gas measurements from GEO, by building on the heritage of five spectrometers flown in low-earth-orbit (LEO). These LEO instruments measure the needed spectra, although at coarse spatial and temporal resolutions, to the precisions required for TEMPO and use retrieval algorithms developed for them by TEMPO Science Team members and currently running in operational environments. This makes TEMPO an innovative use of a well-proven technique, able to produce a revolutionary data set.

TEMPO provides much of the atmospheric measurement capability recommended for GEO-CAPE in the 2007 National Research Council Decadal Survey, Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond. GEO-CAPE is not planned for implementation this decade. However, instruments from Europe (Sentinel 4) and Asia (GEMS) will form parts of a global GEO constellation for pollution monitoring later this decade, with a major focus on intercontinental pollution transport. TEMPO will launch at a prime time to be a component of this constellation.

description: Self-management is generally considered a dynamic and collaborative process by individuals and caregivers to manage a chronic condition. Self-management has recently emerged as a promising strategy for stroke rehabilitation. This scoping review aims to examine and summarize self-management strategies utilized by stroke survivors for stroke rehabilitation. PubMed, Scopus, CINAHL (EBSCO), Embase, and ProQuest were searched for articles published between January 2010 and December 2021. Studies were selected if they were published in English in a peer-reviewed journal, utilized a non-experimental research design, and focused on adult stroke survivors. All relevant information from the included articles was extracted in a systematic way using a pre-developed data extraction form. Two authors performed data extraction and quality evaluation independently. All issues were resolved through discussion among the authors. We narratively summarized the findings of 15 quantitative, qualitative, and mixed-method studies, including a total of 1,494 stroke survivors. The stroke survivors used a range of self-management strategies for their stroke rehabilitation, including domains related to lifestyle, social support, communication, knowledge and information, and goal-setting. Gender, age, stroke-related disability, fatigue, self-management education, social support, and communication with others were found to be associated with self-management use in stroke rehabilitation. This scoping review provides an important overview on stroke survivors’ use of self-management strategies and their experience. Their use of self-management strategies is complicated and multifaceted, comprising several domains and involving a diverse range of approaches and personal experiences. However, we identified several gaps in the literature and more research is required.

description: About 3 sigma deviation from the standard model prediction of muon anomalous magnetic moment (muon g-2) has been reported. We consider new physics beyond the standard model which has new Yukawa interactions with muon. We compute new contributions to muon g-2 and corrections to electroweak observables, and show the consistent region of parameter space. We find that in a simple model where the chirality flip of muon occurs only in the external muon line in one-loop muon g-2 diagrams, it is necessary to introduce the relatively large new Yukawa coupling and the electroweak scale new particles. On the other hand, in a model where the chirality flip can occur in the internal fermion line of one loop muon g-2 diagrams, we can obtain favorable g-2 contributions without large Yukawa coupling, and they are consistent with the precision electroweak observables. Finally, we discuss effects of new particles for muon g-2 on the Higgs boson decay h to 2 photons and direct productions of these particles at the LHC experiment.

description: An extreme-mass-ratio burst (EMRB) is a gravitational wave signal emitted when a compact object passes through periapsis on a highly eccentric orbit about a much more massive object, in our case a stellar mass object about a 10^6 M_sol black hole. EMRBs are a relatively unexplored means of probing the spacetime of massive black holes (MBHs). We conduct an investigation of the properties of EMRBs and how they could allow us to constrain the parameters, such as spin, of the Galaxy's MBH. We find that if an EMRB event occurs in the Galaxy, it should be detectable for periapse distances r_p < 65 r_g for a μ= 10 M_sol orbiting object, where r_g = GM/c^2 is the gravitational radius. The signal-to-noise ratio scales as ρ~ -2.7 log(r_p/r_g) + log(μ/M_sol) + 4.9. For periapses r_p < 10 r_g, EMRBs can be informative, and provide good constraints on both the MBH's mass and spin. Closer orbits provide better constraints, with the best giving accuracies of better than one part in 10^4 for both the mass and spin parameter.

title: How to be successful in hyflex learning - student and teacher’s perspectives
Creators: name: Suresh Kumar, Dharini

description: The hyflex learning mode has benefitted the learning and teaching community by providing a flexible learning environment amidst the pandemic challenges. In this thesis, I build on literature about student satisfaction and academic self-efficacy (ASE) in hyflex learning compared to different learning modes (distance vs. hyflex vs. traditional in-person) following the Hyflex core principles as a foundation, as hyflex mode provides an excellent alternative for the teaching and learning community even after the pandemic. I explore how experiential learning and the learning modes impact students’ satisfaction and self-efficacy mediated by the four core principles. This thesis addresses the literature gap by examining if and how students perceive equal learning opportunities and experiences. Two studies were conducted to understand student and teacher perspectives of hyflex classes. Study 1 focused on unveiling the challenges of implementing a successful hyflex course from a teacher’s perspective. Study 2 compared student satisfaction and academic self-efficacy in the different learning modes (distance vs. hyflex and traditional in-person vs. hyflex). The thesis contributes by revealing the definition of hyflex classes, addressing the challenges faced by both the teaching and learning communities, reviewing their recommendations, and examining the pros and cons of hyflex learning. The study also talks about the challenges faced by the teaching community in implementing a hyflex course and discusses ways to better learning. Theoretical contributions, practical implications, and an agenda for future research are discussed.

description: The ability of migratory birds to orient relative to the Earth's magnetic field is believed to involve a coherent superposition of two spin states of a radical electron pair. However, the mechanism by which this coherence can be maintained in the face of strong interactions with the cellular environment has remained unclear. This Letter addresses the problem of decoherence between two electron spins due to hyperfine interaction with a bath of spin 1/2 nuclei. Dynamics of the radical pair density matrix are derived and shown to yield a simple mechanism for sensing magnetic field orientation. Rates of dephasing and decoherence are calculated ab initio and found to yield millisecond coherence times, consistent with behavioral experiments.
title: An Autoethnography on Teaching Antiracism in the Current Sociopolitical Environment

description: In the course of American history, students from historically marginalized and underrepresented communities have been left out of the educational conversation. This has created an era of undereducated citizens who have historically used privilege to oppress students from these communities. Teachers must use their privilege to teach antiracist education that specifically encourages students to stand up for the justice needed to make a better world. Although this education is important, politicians, parents, and school board administrators are consistently putting teachers in an awkward position when they work towards implementing antiracist education by enacting policies that force them to stop or threatening termination for speaking on divisive concepts. Through this autoethnography, I have analyzed my own practices and reflected on my teaching through autobiographies, journal entries, and book studies so that readers understand the struggles of a teacher who cares about, and implements, antiracist education in the current politically charged social environment.
On Nontrivial Solutions around a Marginal Solution in Cubic Superstring Field Theory

description: We construct tachyon vacuum and half-brane solutions, using an extension of KBc algebra, in the theory around a type of identity-based marginal solutions in modified cubic superstring field theory. With explicit computations, we find that their vacuum energies are the same as those of corresponding solutions around the original theory. It implies that the vacuum energy for the identity-based marginal solution vanishes although straightforward computation of it is subtle. We also evaluate the gauge invariant overlaps for those nontrivial solutions. The values for them are deformed according to the marginal solution in the same way as the case of bosonic string field theory.

description: Gene networks exhibiting oscillatory dynamics are widespread in biology. The minimal regulatory designs giving rise to oscillations have been implemented synthetically and studied by mathematical modeling. However, most of the available analyses generally neglect the coupling of regulatory circuits with the cellular "chassis" in which the circuits are embedded. For example, the intracellular macromolecular composition of fast-growing bacteria changes with growth rate. As a consequence, important parameters of gene expression, such as ribosome concentration or cell volume, are growth-rate dependent, ultimately coupling the dynamics of genetic circuits with cell physiology. This work addresses the effects of growth rate on the dynamics of a paradigmatic example of genetic oscillator, the repressilator. Making use of empirical growth-rate dependences of parameters in bacteria, we show that the repressilator dynamics can switch between oscillations and convergence to a fixed point depending on the cellular state of growth, and thus on the nutrients it is fed. The physical support of the circuit (type of plasmid or gene positions on the chromosome) also plays an important role in determining the oscillation stability and the growth-rate dependence of period and amplitude. This analysis has potential application in the field of synthetic biology, and suggests that the coupling between endogenous genetic oscillators and cell physiology can have substantial consequences for their functionality.

description: We study the theory that contains two spin-2 fields. This theory can be regarded as a simplified version of higher spin gravity in AdS3. It can be formulated either in the first order formulation or in the second order formulation. From the first order formulation we construct the black holes in the theory and study the thermodynamics of this black holes with the help of dual holographic OPE. From the higher spin point of view, this black hole is most naturally regarded as a black hole with a spin-2 hair. In the second order formulation, we obtain an action for the metric and extra spin-2 fields and analyze the corresponding black holes. Even though for some simple cases, the conventional notions, such as the horizon, may help us to read part of the information of the black hole, they break down in generic cases. On the other hand, the action in the second order formulation could be rewritten in the form of a decoupled AdS3 bi-gravity. Moreover, the entropy of the black hole with the spin-2 hair could be reproduced from the AdS3 bi-gravity in the Euclidean path-integral formalism.

description: The sea and maritime spaces have long been neglected in the field of Jewish studies despite their relevance in the context of Jewish religious texts and historical narratives. The images of Noah’s arche, king Salomon’s maritime activities or the miracle of the parting of the Red Sea immediately come into mind, however, only illustrate a few aspects of Jewish maritime activities. Consequently, the relations of Jews and the sea has to be seen in a much broader spatial and temporal framework in order to understand the overall importance of maritime spaces in Jewish history and culture. Almost sixty years after Samuel Tolkowsky’s pivotal study on maritime Jewish history and culture and the publication of his book “They Took to the Sea” in 1964, this volume of PaRDeS seeks to follow these ideas, revisit Jewish history and culture from different maritime perspectives and shed new light on current research in the field, which brings together Jewish and maritime studies. The articles in this volume therefore reflect a wide range of topics and illustrate how maritime perspectives can enrich our understanding of Jewish history and culture and its entanglement with the sea – especially in modern times. They study different spaces and examine their embedded narratives and functions. They follow in one way or another the discussions which evolved in the last decades, focused on the importance of spatial dimensions and opened up possibilities for studying the production and construction of spaces, their influences on cultural practices and ideas, as well as structures and changes of social processes. By taking these debates into account, the articles offer new insights into Jewish history and culture by taking us out to “sea” and inviting us to revisit Jewish history and culture from different maritime perspectives.

description: Recent data indicates that the cosmic UV emissivity decreased with decreasing redshift z near the end of reionization. Lacking evidence for very massive early stars, this could signal a decline with time in the mass-averaged escape fraction of ionizing radiation from galaxies at z > 6. We calculate the evolution of ionization fronts in dark matter halos which host gas in hydrostatic equilibrium at its cooling temperature floor (T~10^4 K for atomic hydrogen). We find a high escape fraction only for the lowest mass halos (with M< 10^8.7 Msun at (1+z)=10) provided their star formation efficiency f_star > 10^-3. Since the low-mass galaxy population is depleted by radiative feedback, we find that indeed decreases with time during reionization.

description: We have investigated the polarization response of a dielectric to intense few-cycle laser pulses with a focus on interband tunnelling. Once charge carriers are created in an initially empty conduction band, they make a significant contribution to the polarization response. In particular, the coherent superposition of conduction- and valence-band states results in quantum beats. This quantum-beat part of the polarization response is affected by the excitation dynamics and attosecond-scale motion of charge carriers in an intense laser field. Our analysis shows that, with the onset of Bloch oscillations or tunnelling, the nonlinear polarization response becomes sensitive to the carrier-envelope phase of the laser pulse.
