Spin echo without an external permanent magnetic field

description: The spin echo techniques aim at the elimination of the effect of a random magnetic field on the spin evolution. These techniques conventionally utlize the application of a permanent field which is much stronger than the random one. The strong field, however, may also modify the magnetic response of the medium containing the spins, thus altering their ``natural'' dynamics. We suggest an iterative scheme for generating a sequence of pulses which create an echo without an external permanent field. The approximation to the ideal echo improves with the sequence length.

description: Characterization of phases of soft matter systems is a challenge faced in many physicochemical problems. For polymorphic fluids it is an even greater challenge. Specifically, glass forming fluids, as water, can have, besides solid polymorphism, more than one liquid and glassy phases, and even a liquid-liquid critical point. In this sense, we apply a neural network (NN) algorithm to analyze the phase behavior of a core-softened mixture of core-softened CSW fluids that have liquid polymorphism and liquid-liquid critical points, similar to water. We also apply the NN to mixtures of CSW fluids and core-softened alcohols models. We combine and expand two methods based on bond-orientational order parameters to study mixtures, applied to mixtures of hardcore fluids by Boattini and co-authors [Molecular Physics 116, 3066-3075 (2018)] and to supercooled water by Martelli and co-authors [The Journal of Chemical Physics 153, 104503 (2020)], to include longer range coordination shells. With this, the trained neural network (NN) was able to properly predict the crystalline solid phases, the fluid phases and the amorphous phase for the pure CSW and CSW-alcohols mixtures with high efficiency. More than this, information about the phase populations, obtained from the NN approach, can help verify if the phase transition is continuous or discontinuous, and also to interpret how the metastable amorphous region spreads along the stable high density fluid phase. These findings help to understand the behavior of supercooled polymorphic fluids and extend the comprehension of how amphiphilic solutes affect the phases behavior.

description: We study the Gluino-Glue operator in the context of Supersymmetric ${\cal N}{=}1$ Yang-Mills (SYM) theory. This composite operator is gauge invariant, and it is directly connected to light bound states of the theory; its renormalization is very important as a necessary step for the study of low-lying bound states via numerical simulations. We make use of a Gauge-Invariant Renormalization Scheme (GIRS). This requires the calculation of the Green's function of a product of two Gluino-Glue operators, situated at distinct space-time points. Within this scheme, the mixing with non-gauge invariant operators which have the same quantum numbers is inconsequential. We compute the one-loop conversion factor relating the GIRS scheme to $\overline{\rm MS}$. This conversion factor can be used in order to convert to $\overline{\rm MS}$ Green's functions which are obtained via lattice simulations and are renormalized nonperturbatively in GIRS.

description: Graphene kinks are topological states of buckled graphene membranes. We show that when a moving kink encounters a constriction, there are three general classes of behavior: reflection, trapping, and transmission. Overall, constriction is characterized by an attractive potential. In the case of a simple symmetric constriction, the kink potential energy has a relatively deep minimum surrounded by energy barriers. However, the potential energy alone does not fully define the class of behavior: the effect of a resonant reflection was observed in our simulations. Moreover, we demonstrate that asymmetric constrictions can transform kinks from one type into another. MD simulation results are compared with predictions of the classical $ϕ^4$ model.

description: PageRank, the prestige measure for Web pages used by Google, is the stationary probability of a peculiar random walk on directed graphs, which interpolates between a pure random walk and a process where all nodes have the same probability of being visited. We give some exact results on the distribution of PageRank in the cases in which the damping factor q approaches the two limit values 0 and 1. When q -> 0 and for several classes of graphs the distribution is a power law with exponent 2, regardless of the in-degree distribution. When q -> 1 it can always be derived from the in-degree distribution of the underlying graph, if the out-degree is the same for all nodes.

description: We study the percolation properties of graph partitioning on random regular graphs with N vertices of degree $k$. Optimal graph partitioning is directly related to optimal attack and immunization of complex networks. We find that for any partitioning process (even if non-optimal) that partitions the graph into equal sized connected components (clusters), the system undergoes a percolation phase transition at $f=f_c=1-2/k$ where $f$ is the fraction of edges removed to partition the graph. For optimal partitioning, at the percolation threshold, we find $S \sim N^{0.4}$ where $S$ is the size of the clusters and $\ell\sim N^{0.25}$ where $\ell$ is their diameter. Additionally, we find that $S$ undergoes multiple non-percolation transitions for $f

description: The diquark structure in baryons is commonly accepted as a reasonable approximation which can much simplify the picture and reduce the length of calculations. However, a diquark by no means is a point-like particle, even though it is treated as a whole object. Therefore, to apply the diquark picture to the phenomenological calculations, at the effective vertices for the diquark-gauge boson interactions, suitable form factors must be introduced to compensate the effects caused by the inner structure of the diquark. It is crucial to derive the appropriate form factors for various interactions. In this work, we use the Bethe-Salpeter equation to derive such form factors and numerically evaluate their magnitudes.

description: BOSS-EUVLG1 is the most ultraviolet (UV) and Ly$α$ luminous galaxy detected so far in the Universe, going through a very active starburst phase, and forming stars at a rate (SFR) of 955 $\pm$ 118 M$_{\odot}$ yr$^{-1}$. We report the detection of a broad H$α$ component carrying 25% of the total H$α$ flux. The broad H$α$ line traces a fast and massive ionized gas outflow characterized by a total mass, $\log(M_{out}[M_{\odot}]),$ of 7.94 $\pm$ 0.15, an outflowing velocity (V$_{out}$) of 573 $\pm$ 151 km s$^{-1}$, and an outflowing mass rate ($\dot{M}_{out}$) of 44 $\pm$ 20 M$_{\odot}$ yr$^{-1}$. The presence of the outflow in BOSS-EUVLG1 is also supported by the identification of blueshifted UV absorption lines in low and high ionization states. The energy involved in the H$α$ outflow can be explained by the ongoing star formation without the need for an Active Galactic Nucleus. The derived low mass loading factor ($η$= 0.05 $\pm$ 0.03) indicates that although massive, this phase of the outflow can not be relevant for the quenching of the star formation. In addition, only a small fraction ($\leq$ 15%) of the ionized outflowing material with velocities above 372 km s$^{-1}$ could escape the gravitational potential, and enrich the surrounding circum-galactic medium at distances above tens of kpc. The ionized phase of the outflow does not carry the mass and energy to play a relevant role neither in the evolution of the host galaxy nor in the enrichment of the intergalactic medium. Other phases of the outflow could be carrying most of the outflow energy and mass in the form of hot X-ray emitting gas as predicted by some recent simulations. The expected emission of the extended X-ray emitting halo associated with the outflow in BOSS-EUVLG1 and similar galaxies could be detected with the future X-ray observatory, {\it ATHENA} but could not be resolved spatially.

description: The aim of the present thesis is to identify and present the impact of economic data on the interpretation of the Constitution and to define the current interpretive role of the judge in the field of control of economic policy measures. In the first chapter there is a brief reference to the methodology of constitutional interpretation and the interpretive role of the judge in general, as well as to interpretative tools used in constitutional interpretation. Subsequently, in the second chapter there is an analysis of the invocation of economic conditions in the explanation of vague constitutional concepts and their use in judicial reasoning in order to establish the declaration of constitutionality of economic policy measures. Furthermore, there is an examination of the way in which the same economic conditions are used inversely in cases where the constitutional rights are deemed to be excessively restricted. Subsequently, in the third chapter there is an attempt to determine how economic conditions shape the judge's interpretative role in the control of constitutionality, not just of purely economic measures, but of all the measures without exception
Sonochemical reactor design based on electrostatic film transducers
Creators: name: Bolleman, Brent John
Publisher: name: University of British Columbia

description: Sonochemistry is a relatively new field of chemistry which uses intense sound energy to influence chemical reactions. Laboratory investigations have indicated that a number of commercially important chemical processes can be improved by sonochemistry techniques. However, there does not appear to be any sonochemical reactor designs which are feasible for use at the industrial scale. All the reactor designs proposed thus far utilize piezoelectric or magnetostrictive transducers for generating the sound energy. These transducers are widely used for other sound applications, but their properties make construction of an industrial-scale sonochemical reactor complex and expensive. A new sonochemical reactor design based on electrostatic film transducers is introduced here which may present a breakthrough in the economic feasibility of industrial sonochemical processing. A working prototype of this reactor was not achieved because the maximum sound pressure which could be obtained from simple electrostatic film transducer prototypes was only a fraction of that required for cavitation. An acoustic model of the reactor was developed and experimentally confirmed which showed that the reactor sound pressure was limited primarily by excessive damping in the transducer. Commercialization of this technology will first require the construction of a high-pressure electrostatic film transducer with minimal damping. This could then be followed by lab-scale reactor manufacture, pilot plant evaluations, and finally industrial-scale implementation.

Συγκεκριμένα, χρησιμοποιώντας πάνελ δεδομένα από ένα δείγμα 73 χωρών για την περίοδο 1995-2015, εξετάσθηκαν δύο υποθέσεις: 1) Οι χώρες που βασίζονται περισσότερο στους έμμεσους φόρους τείνουν να εμφανίζουν υψηλότερα επίπεδα διαφθοράς και 2) οι χώρες με πολυπλοκότερο φορολογικό σύστημα τείνουν να εμφανίζουν υψηλότερα επίπεδα διαφθοράς. Τα αποτελέσματα της Μεθόδου Ελαχίστων Τετραγώνων δείχνουν ότι οι χώρες που βασίζονται περισσότερο στους έμμεσους φόρους τείνουν να εμφανίζουν υψηλότερα επίπεδα διαφθοράς, καθώς επίσης και ότι τα υψηλά επίπεδα πολυπλοκότητας του φορολογικού συστήματος συνδέονται με υψηλά επίπεδα διαφθοράς. Τα αποτελέσματα της Γενικευμένης Μεθόδου Ροπών επιβεβαιώνουν την ισχύ της υπόθεσης ότι οι χώρες που βασίζονται περισσότερο στους άμεσους φόρους τείνουν να εμφανίζουν χαμηλότερα επίπεδα διαφθοράς, με μειωμένο ωστόσο βαθμό επίδρασης. Αντίθετα, προκύπτει ότι η επίδραση της πολυπλοκότητας του φορολογικού συστήματος στη διαφθορά δεν παρουσιάζει στατιστική σημαντικότητα. Το βασικό συμπέρασμα που προκύπτει από τη συγκεκριμένη ανάλυση είναι ότι η επιλογή του μίγματος φόρων συνδέεται με τη διαφθορά, γεγονός που πρέπει να λαμβάνεται υπόψη κατά το σχεδιασμό της φορολογικής πολιτικής
description: The aim of this paper is the empirical investigation of the tax structure impact on the corruption. Specifically, using a sample of 73 countries over the period 1995-2015 we examined the following two hypotheses: a) countries relying more on indirect taxes tend to present higher levels of corruption and b) countries having more complex tax systems tend to be linked with higher levels of corruption. The results of the Ordinary Least Squares (OLS) Method indicated that countries relying more on indirect taxes tend to have higher levels of corruption, whereas complex tax systems are associated with higher levels of corruption. The results of the Generalized Method of Moments (GMM) supported the hypothesis that countries relying more on direct taxes tend to have lower levels of corruption, though with a lower degree of impact. On the contrary, the tax complexity effect on corruption was found statistically insignificant. The key finding of the present analysis is that the choice of tax mix is linked with corruption, a fact that should be taken into consideration by the tax policy designers

description: We derive the general exact forms of the Wigner function, of mean values of conserved currents, of the spin density matrix, of the spin polarization vector and of the distribution function of massless particles for the free Dirac field at global thermodynamic equilibrium with rotation and acceleration, extending our previous results obtained for the scalar field. The solutions are obtained by means of an iterative method and analytic continuation, which leads to formal series in thermal vorticity. In order to obtain finite values, we extend to the fermionic case the method of analytic distillation introduced for bosonic series. The obtained mean values of the stress-energy tensor, vector and axial currents for the massless Dirac field are in agreement with known analytic results in the special cases of pure acceleration and pure rotation. By using this approach, we obtain new expressions of the currents for the more general case of combined rotation and acceleration and, in the pure acceleration case, we demonstrate that they must vanish at the Unruh temperature.

description: The purpose of this study is, in principle, to investigate the convergence of carbon dioxide emissions in developing countries and then to examine the convergence of carbon dioxide emissions in these countries on the basis of the level of growth and the existence and effective functioning of the institutional environment. The data sample consists of 140 developing countries and the examined period is 2002-2014. Panel unit root tests were applied and provided evidence in favour of stochastic convergence. Next, the Generalized Method of Moments (GMM) showed that growth, government effectiveness and regulatory quality affect convergence, which means that in order to achieve convergence, they should be evaluated accordingly amongst policy tools.

description: Controlling the spin dynamics and spin lifetimes is one of the main challenges in spintronics. To this end, the study of the spin diffusion in two-dimensional electron gases (2DEGs) shows that when the Rashba and Dresselhaus spin-orbit couplings (SOC) are balanced, a persistent spin helix regime arises. There, a striped spin pattern shows a long lifetime, limited only by the cubic Dresselhaus SOC, and its dynamics can be controlled by in-plane drift fields. Here, we derive a spin diffusion equation for non-degenerate two-subbands 2DEGs. We show that the intersubband scattering rate, which is defined by the overlap of the subband densities, enters as a new nob to control the spin dynamics, and can be controlled by electric fields, being maximum for symmetric quantum wells. We find that for large intersubband couplings the dynamics follow an effective diffusion matrix given by approximately half of the subband-averaged matrices. This extra 1/2 factor arises from Matthiessen's rule summing over the intra- and intersubband scattering rates, and leads to a reduced diffusion constant and larger spin lifetimes. We illustrate our findings with numerical solutions of the diffusion equation with parameters extracted from realistic Schrödinger-Poisson calculations.

description: We show that the breakdown of time-reversal invariance, confirmed by the recent polar Kerr effect measurements in the cuprates, implies the existence of an anomalous Nernst effect in the pseudogap phase of underdoped cuprate superconductors. Modeling the time-reversal-breaking ordered state by the chiral d-density-wave state, we find that the magnitude of the Nernst effect can be sizable even at temperatures much higher than the superconducting transition temperature. These results imply that the experimentally found Nernst effect at the pseudogap temperatures may be due to the chiral d-density wave ordered state with broken time-reversal invariance.

description: We study theoretically spin pumping in bilayers consisting of superconductors and antiferromagnetic insulators. We consider both compensated and uncompensated interfaces and include both the regular scattering channel and the Umklapp scattering channel. We find that at temperatures close to the critical temperatures and precession frequencies much lower than the gap, the spin-current is enhanced in superconductors as compared to normal metals. Otherwise, the spin-current is suppressed. The relevant precession frequencies where the spin-current in SC/AFI is enhanced compared to NM/AFI is much lower than the typical resonance frequencies of antiferromagnets, which makes the detection of this effect experimentally challenging. A possible solution lies in the shifting of the resonance frequency by a static magnetic field.

description: We have developed a new scheme to treat a multiphase interstellar medium in smoothed particle hydrodynamics simulations of galaxy formation. This scheme can represent a co-spatial mixture of cold and hot ISM components, and is formulated without scale-dependent parameters. It is thus particularly suited to studies of cosmological structure formation where galaxies with a wide range of masses form simultaneously. We also present new algorithms for energy and heavy element injection by supernovae, and show that together these schemes can reproduce several important observed effects in galaxy evolution. Both in collapsing systems and in quiescent galaxies our codes can reproduce the Kennicutt relation between the surface densities of gas and of star formation. Strongly metal-enhanced winds are generated in both cases with ratios of mass-loss to star formation which are similar to those observed. This leads to a self-regulated cycle for star formation activity. The overall impact of feedback depends on galaxy mass. Star formation is suppressed at most by a factor of a few in massive galaxies, but in low-mass systems the effects can be much larger, giving star formation an episodic, bursty character. The larger the energy fraction assumed available in feedback, the more massive the outflows and the lower the final stellar masses. Winds from forming disks are collimated perpendicular to the disk plane, reach velocities up to 1000 km/s, and efficiently transport metals out of the galaxies. The asymptotically unbound baryon fraction drops from >95 per cent to ~30 per cent from the least to the most massive of our idealised galaxies, but the fraction of all metals ejected with this component exceeds 60 per cent regardless of mass. Such winds could plausibly enrich the intergalactic medium to observed levels.

Contributions to $ZZV^\ast$ ($V=γ,Z,Z'$) couplings from $CP$ violating flavor changing couplings

description: The one-loop contributions to the trilinear neutral gauge boson couplings $ZZV^\ast$ ($V=γ,Z,Z'$), parametrized in terms of one $CP$-conserving $f_5^{V}$ and one $CP$-violating $f_4^{V}$ form factors, are calculated in models with $CP$-violating flavor changing neutral current couplings mediated by the $Z$ gauge boson and an extra neutral gauge boson $Z'$. Analytical results are presented in terms of both Passarino-Veltman scalar functions and closed form functions. Constraints on the vector and axial couplings of the $Z$ gauge boson $\left|g_{VZ}^{tu}\right|< 0.0096$ and $\left|g_{VZ}^{tc}\right|<0.011$ are obtained from the current experimental data on the $t\rightarrow Z q$ decays. It is found that in the case of the $ZZγ^\ast$ vertex the only non-vanishing form factor is $f_5^γ$, which can be of the order of $10^{-3}$, whereas for the $ZZZ^\ast$ vertex both form factors $f_5^{Z}$ and $f_4^{Z}$ are non-vanishing and can be of the order of $10^{-6}$ and $10^{-5}$, respectively. Our estimates for $f_5^γ$ and $f_5^{Z}$ are smaller than those predicted by the standard model, where $f_4^{Z}$ is absent up to the one loop level. We also estimate the $ZZ{Z'}^{*}$ form factors arising from both diagonal and non-diagonal $Z'$ couplings within a few extension models. It is found that in the diagonal case $f_{5}^{Z'}$ is the only non-vanishing form factor and its real and imaginary parts can be of the order of $10^{-1}-10^{-2}$ and $ 10^{-2}-10^{-3}$, respectively, with the dominant contributions arising from the light quarks and leptons. In the non-diagonal case $f_{5}^{Z^\prime}$ can be of the order of $10^{-4}$, whereas $f_4^{Z'}$ can reach values as large as $10^{-7}-10^{-8}$, with the largest contributions arising from the $Z'tq$ couplings.
Measurement of the electroweak production of Z$γ$ and two jets in proton-proton collisions at $\sqrt{s} =$ 13 TeV and constraints on anomalous quartic gauge couplings

description: The first observation of the electroweak (EW) production of a Z boson, a photon, and two forward jets (Z$γ$jj) in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. A data set corresponding to an integrated luminosity of 137 fb$^{-1}$, collected by the CMS experiment at the LHC in 2016-2018 is used. The measured fiducial cross section for EW Z$γ$jj is $σ_{\mathrm{EW}}$ = 5.21 $\pm$ 0.52 (stat) $\pm$ 0.56 (syst) fb = 5.21 $\pm$ 0.76 fb. Single-differential cross sections in photon, leading lepton, and leading jet transverse momenta, and double-differential cross sections in $m_{\mathrm{jj}}$ and $\lvertΔη_{\mathrm{jj}}\rvert$ are also measured. Exclusion limits on anomalous quartic gauge couplings are derived at 95% confidence level in terms of the effective field theory operators $\mathrm{M}_{0}$ to $\mathrm{M}_{5}$, $\mathrm{M}_{7}$, $\mathrm{T}_{0}$ to $\mathrm{T}_{2}$, and $\mathrm{T}_{5}$ to $\mathrm{T}_{9}$.

The Theory of Local Inertial Mass Reduction: Foundations and Astrophysical Implications
Creators: name: Universidade Federal de Lavras
Publisher: name: Zenodo
Year: 2025

description: Abstract:

 

This work presents the Theory of Local Inertial Mass Reduction (LIMR), a novel relativistic framework in which the inertial mass of a body becomes a local function of physical conditions such as magnetic field intensity, rotation, and plasma density. The theory introduces a scalar field ψ(x^μ) that modulates inertia without altering spacetime curvature, leading to a modified form of Newton’s second law and Einstein's field equations.

 

The LIMR theory provides an alternative explanation for phenomena typically attributed to dark matter, such as galactic rotation curves and gravitational anomalies, by reducing the local inertial resistance rather than invoking additional invisible mass. Its equations are derived from a covariant Lagrangian, ensuring consistency with general relativity, and it offers testable predictions on planetary orbits, laboratory experiments, and cosmological observations.

 

This publication aims to establish a conceptual and mathematical foundation for future experimental validation and invites critical review from the scientific community.

description: Two previously proposed conjectures--gravitational trans-Planckian particle creation in the expanding universe, and the existence of ultra-heavy stable particles with masses up to the Planck scale (wimpzillas)--are combined in a proposal for trans-Planckian particle creation of wimpzillas. This new scenario leads to a huge enhancement in their production compared to mechanisms put forward earlier. As a result, it requires the trans-Planckian particle creation parameter to be rather small to avoid overproduction of such particles, much less than that is required for observable effects in the primordial perturbation spectrum. This ensures also that wimpzillas are mainly created at the end of primordial inflation. Conditions under which trans-Planckian wimpzillas can constitute the present dark matter are determined.

Narrow band microwave radiation from a biased single-Cooper-pair transistor

description: We show that a single-Cooper-pair transistor (SCPT) electrometer emits narrow-band microwave radiation when biased in its sub-gap region. Photo activation of quasiparticle tunneling in a nearby SCPT is used to spectroscopically detect this radiation, in a configuration that closely mimics a qubit-electrometer integrated circuit. We identify emission lines due to Josephson radiation and radiative transport processes in the electrometer, and argue that a dissipative superconducting electrometer can severely disrupt the system it attempts to measure.

Extracting cosmological parameters from N-body simulations using machine learning techniques

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We make use of snapshots taken from the Quijote suite of simulations, consisting of 2000 simulations where five cosmological parameters have been varied ($Ω_m$, $Ω_b$, $h$, $n_s$ and $σ_8$) in order to investigate the possibility of determining them using machine learning techniques. In particular, we show that convolutional neural networks can be employed to accurately extract $Ω_m$ and $σ_8$ from the N-body simulations, and that these parameters can also be found from the non-linear matter power spectrum obtained from the same suite of simulations using both random forest regressors and deep neural networks. We show that the power spectrum provides competitive results in terms of accuracy compared to using the simulations and that we can also estimate the scalar spectral index $n_s$ from the power spectrum, at a lower precision.
