description: In the gravitational field of a Schwarzschild-like black hole, particles infalling from rest at infinity, and black hole "wind" particles with relativistic velocity leaking radially out from the nominal horizon, both have the same magnitude of velocity at any radius from the hole. Hence when equally massive infalling and wind particles collide at any radius, they yield collision products with zero center of mass radial velocity, which can then nucleate star formation at the collision radius. We suggest that this gives a mechanism by which a central black hole can catalyze galaxy formation. For disk galaxies, this mechanism explains the observed approximately exponential falloff of the surface brightness with radius, and gives an estimate of the associated scale length.

description: In the context of optical interferometry, only undersampled power spectrum and bispectrum data are accessible. It poses an ill-posed inverse problem for image recovery. Recently, a tri-linear model was proposed for monochromatic imaging, leading to an alternated minimization problem. In that work, only a positivity constraint was considered, and the problem was solved by an approximated Gauss-Seidel method. In this paper, we propose to improve the approach on three fundamental aspects. Firstly, we define the estimated image as a solution of a regularized minimization problem, promoting sparsity in a fixed dictionary using either an $\ell_1$ or a weighted-$\ell_1$ regularization term. Secondly, we solve the resultant non-convex minimization problem using a block-coordinate forward-backward algorithm. This algorithm is able to deal both with smooth and non-smooth functions, and benefits from convergence guarantees even in a non-convex context. Finally, we generalize our model and algorithm to the hyperspectral case, promoting a joint sparsity prior through an $\ell_{2,1}$ regularization term. We present simulation results, both for monochromatic and hyperspectral cases, to validate the proposed approach.

description: Cosmic microwave background radiation can supply us some most significant parts of the information on the universe. Some researchers believe that The gravitational system cannot be decribed by the standard statistical mechanics. In this article we apply Tsallis nonextensive statistical mechanics to investigate CMB spectrum and related cosmological processes. Based on recent observational data we find that the nonextensive statistical mechanics can modify the values of related physical quantites. Since the value of physical quantites have changed, some processes, such as recombination, can be affected. We have investigated the anisotropy of the CMB for two effects: the dipole anisotropy of CMB and the Sunyaev-Zel'dovich effect. We find that the dipole anisotropy of CMB cannot be modified by the nonextensive statistical mechanics. However, the standard result of the Sunyaev-Zel'dovich effect should be modified by nonextensive statistical mechanics. In principle, future work can distinguish these effects.
title: Numerical Methods for the Simulation of the Acoustics of Multiphase Flows
Creators: name: Friedrich, Jonas
Publisher: name: UNSPECIFIED
Year: 2024

description: The noise reduction of technical systems has become one of the main challenges in the twenty-first century. In order to tackle this challenge, numerical simulations are a crucial part in the process of understanding the physical mechanisms of sound generation. Nevertheless, experiments have been traditionally used to study the complex phenomenon of sound generated by multiphase flows since there were no suitable numerical methods available. For this reason, a numerical framework for simulating acoustics produced by low Mach number multiphase flows is presented within this work.
The motion of the multiphase flow is described by a single set of the Navier-Stokes equations. Various phases in the computational domain are treated as one fluid with variable material properties. The distribution of the phases is advected with the Volume of Fluid method based on a high resolution scheme methodology. To account surface tension, a singular term formulated by the Continuous Surface Tension method is added to the governing equations. For surface tension dominated flows, the accuracy of the forces around the interface is greatly dependent on the interface curvature computation. Therefore, different improvement strategies applied to curvature computation methods along with a machine learning approach are introduced and analyzed.
Different orders in energy, length and time scales of the acoustics and the flow lead to a segregated handling. An acoustic/viscous splitting approach is employed for the computation of the acoustics. After the multiphase flow field is obtained, the generation and propagation of the acoustic waves is determined on the basis of the linearized Euler equations. The fluid and acoustic sets of equations are both discretized with the Finite Volume method in the in-house solver FASTEST. A one-way coupling between the two physical disciplines, justified by the difference in the characteristic scales, is accomplished by an acoustic source term derived from the unsteady flow field. By adapting the acoustic source term to the multiphase environment, the difficulties of a moving interface are overcome. The coupled validation test cases show the expected results.
For the final part of this work, the developed numerical methods are applied on a three-dimensional test case. A complex and not yet fully understood example of multiphase acoustics is the sound of a water drop impacting into a water pool, as can be heard from a tripping tap. First, the necessary of a very high resolution in space and time as well as an accurate curvature model is demonstrated. Afterwards, the results of the simulations are compared to experimental data with satisfactory agreement and further insights on the sound producing physics are given.

description: We develop a complete analysis of a general entry-exit-scrapping model. In particular, we consider an investment project that operates within a random environment and yields a payoff rate that is a function of a stochastic economic indicator such as the price of or the demand for the project's output commodity. We assume that the investment project can operate in two modes, an "open" one and a "closed" one. The transitions from one operating mode to the other one are costly and immediate, and form a sequence of decisions made by the project's management. We also assume that the project can be permanently abandoned at a discretionary time and at a constant sunk cost. The objective of the project's management is to maximise the expected discounted payoff resulting from the project's management over all switching and abandonment strategies. We derive the explicit solution to this stochastic control problem that involves impulse control as well as discretionary stopping. It turns out that this has a rather rich structure and the optimal strategy can take eight qualitatively different forms, depending on the problems data.
The sigma meson from QCD sum rules for large-$N_c$ Regge spectra

description: The QCD sum rules in the large-$N_c$ limit for the light non-strange vector, axial and scalar mesons are considered assuming a string-like linear spectrum for the radially excited states. We propose a improved method for combined analysis of these channels that gives a reasonable description of the observed spectrum. In the vector-axial case, fixing the pion decay constant and the gluon condensate we obtain more or less physical values for the masses of ground states and the quark condensate. Thus a typical need for this method to fix the mass of some ground state is overcome. Using in the scalar channel the values of presumably universal slope of radial trajectories and the quark condensate obtained in the vector-axial channel, we find that, in contrast to some strong claims in the literature, a prediction of light scalar state with a mass close to the mass of $f_0(500)$ seems to be natural in the considered approach and may follow in a natural way from the Regge phenomenology.
description: Many new discussions concerning the origin of sigma-meson mass, its angular Regge trajectory, comparison with other results etc. are added to Sections 5 and 6. The new text corresponds to the version published in Eur. Phys. J. C

description: The Rains relative entropy of a bipartite quantum state is the tightest known upper bound on its distillable entanglement -- which has a crisp physical interpretation of entanglement as a resource -- and it is efficiently computable by convex programming. It has not been known to be a selective entanglement monotone in its own right. In this work, we strengthen the interpretation of the Rains relative entropy by showing that it is monotone under the action of selective operations that completely preserve the positivity of the partial transpose, reasonably quantifying entanglement. That is, we prove that Rains relative entropy of an ensemble generated by such an operation does not exceed the Rains relative entropy of the initial state in expectation, giving rise to the smallest, most conservative known computable selective entanglement monotone. Additionally, we show that this is true not only for the original Rains relative entropy, but also for Rains relative entropies derived from various Rényi relative entropies. As an application of these findings, we prove, in both the non-asymptotic and asymptotic settings, that the probabilistic approximate distillable entanglement of a state is bounded from above by various Rains relative entropies.

Subjects: subject: 139999 Education not elsewhere classified
subject: FOS: Educational sciences

description: This study utilises the age-old strategy of community conferencing in a case study design to evaluate the effectiveness of using the strategy to reduce school bullying. The community conferencing strategy is founded on the assumption that an individual's emotions are the most effective regulator of his/her behaviour(s). The literature review describes how community conferencing has been used in various contexts in the past and how it is currently used by such organisations as the Queensland Juvenile Justice Department. In the case study, a community conference was conducted with a student bully, his family, peers, the victim and his family, and relevant other educational authorities. The offending student had been previously excluded from school for a period of eighteen months and was in the re-entry phase when another bullying incident occurred. It was at this stage that the education authorities decided to use community conferencing as a means of reducing the reoccurrence of the bullying behaviour in this particular student. In the case study design, multiple data types were used to gather as much data from as many sources as possible that related to the case. Short, relaxed, semi -structured interviews were conducted with the victim, offender supporters, and neutral education authorities. Observations of the conference were recorded unobtrusively by a third party. Various official records of the conference were kept and analysed. Finally a participant' satisfaction questionnaire was completed by those who took part. Findings of the study revealed that four months after the conference the victim felt that the conference made a positive difference to how safe and supported he feels at school. The victim also reported that the bully's behaviour toward him had improved and he reported that he had more confidence to handle a similar situation should another arise in the future. The present study recommends that some changes be made to the community conference procedure but that generally conferencing should be included in the range of strategies used by schools in their anti -bullying policies.
Understanding the Thermoelectric Properties of LaCoO$_{3}$ Compound

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We present the thermoelectric (TE) properties of LaCoO$_{3}$ compound in the temperature range 300-600 K. The experimental value of Seebeck coefficient ($α$) at 300 K is found to be $\sim$635 $μ$V/K. The value of $α$ decreases continuously with increase in temperature and reaches to $\sim$46 $μ$V/K at $\sim$600 K. The electronic and TE properties of the compound have also been investigated by combining the \textit{ab-initio} electronic structures and Boltzmann transport calculations. LSDA plus Hubbard U (U= 2.75 eV) calculation on low spin configuration of the compound gives an energy gap of $\sim$0.5 eV, which is close to the experimentally reported energy gap. The effective mass of holes (\textit{m$^{*}_h$}) at $Γ$ point is nearly two times larger than the value of effective mass of electrons (\textit{m$^{*}_e$}) at FB point along the L and T directions, whereas the \textit{m$^{*}_e$} at FB point along the $Γ$ direction is nearly eight times larger than the value of \textit{m$^{*}_h$} at $Γ$ point along the FB direction. The large effective mass at FB point along the $Γ$ direction suggests that the TE property of this compound is mainly decided by the effective mass of the charge carriers in this direction. The calculated temperature dependent values of $α$ are in fairly good agreement with experimental data in the temperature range 300-360 K, and above this temperature slight deviation is observed. The value of power factor (PF) for \textit{n}-type is $\sim$1.3 times larger the value of \textit{p}-type doped compound at 1100 K. The value of \textit{figure-of-merit} (\textit{ZT}) for \textit{n}-type doped compound is obtained $\sim$0.35 in the temperature range 600-1100 K, which suggests that with appropriate \textit{n}-type doping this compound can be used as a good TE material in the high temperature region.

title: Untersuchung der Freisetzung von Schwefel-, Chlor- und Stickstoffverbindungen bei der Oxyfuel-Verbrennung von Biomasse

Publisher: name: UNSPECIFIED

description: Im Rahmen des Pariser Klimaabkommens von 2015 hat sich die internationale Staatengemeinschaft dazu verpflichtet, die globale Erwärmung auf maximal 1,5 °C zu begrenzen. Diesbezüglich wurde
eine sektorübergreifende Reduktion der anthropogenen Treibhausgasemissionen vereinbart. Die Abscheidung und anschließende Nutzung und Speicherung von Kohlenstoffdioxid (CO₂) aus Kraftwerksabgasen ermöglicht die Reduktion von Emissionen (CCUS – Carbon Capture, Utilisation and Storage). Durch den Einsatz von Biomasse als Brennstoff können negative CO₂-Emissionen erreicht werden. Der Oxyfuel-Prozess stellt eine potenzielle CCUS-Technologie dar. Durch die Verbrennung in einer CO₂-reichen Atmosphäre ergeben sich zahlreiche Änderungen im Verbrennungsverhalten und somit in den Schadstoffemissionen.
In der vorliegenden Dissertation wurde der Einfluss der Oxyfuel-Verbrennung auf die Freisetzung von Schwefel-, Chlor- und Stickstoffverbindungen aus verschiedenen pflanzlichen Biomassen experimentell untersucht. Dazu wurden Experimente mit einer thermogravimetrischen Analyse (TGA) und einem Flugstromreaktor (FSR) durchgeführt.
Mittels der TGA konnten die Freisetzungsschritte bei der thermochemischen Umwandlung des in der Biomasse gebundenen Schwefels, Chlors und Stickstoffs getrennt voneinander beobachtet werden. Die Schwefel- und Stickstoff-Emissionen konnte auf die Zersetzung der im Brennstoff enthaltenen Proteine zurückgeführt werden, die bei unterschiedlichen Temperaturen zerfallen. Die Untersuchungen zeigten die Bildung von Chlormethan (CH₃Cl) und Chlorethan (C₂H₅Cl) neben der Freisetzung von Chlorwasserstoff (HCl).
Mit dem FSR wurden Untersuchungen mit hohen Partikelaufheizraten durchgeführt, welche realen Großfeuerungsanlagen nahe kommen. Die Experimente wurden in unterschiedlichen Atmosphären (N₂, CO₂, O₂/N₂, O₂/CO₂) durchgeführt, um die Schadstofffreisetzung während der Entgasung und der Verbrennung des Brennstoffes zu untersuchen. Reaktortemperatur, Verbrennungsstöchiometrie und Verweilzeit wurden variiert, um den Einfluss der Parameter auf die Schadstofffreisetzung
zu bestimmen. Mit steigender Temperatur wurden weniger Schadstoffe in der N₂- und CO₂-Umgebung emittiert. Eine CO₂-Umgebung hemmte die Bildung von Schwefeldioxid (SO₂) und förderte die von Carbonylsulfid (COS). Bei der konventionellen und der Oxyfuel-Verbrennung wurden geringere Mengen an Schwefel und Chlor emittiert als in der N₂- und CO₂-Atmosphäre. Bei überstöchiometrischen Bedingungen wurden bei der Oxyfuel-Verbrennung 52 % des im Brennstoff enthaltenen Stickstoffs in der Gasphase als Stickstoffmonoxid (NO) nachgewiesen.

description: We investigate the basic properties of Hawking radiation for spherical solutions in $D = 4$ double field theory. We give the expression of the Hawking temperature for the solution and then discuss the results of various limits. We find that for all these limits only Schwarzschild solution and F-JNW solution can generate Hawking radiation. Moreover, we obtain the lower bound on greybody factors $σ_l(ω)$ for the spherical solutions in $D = 4$ double field theory. In particular, we calculate the bound on greybody factors $σ_l(ω)$ for F-JNW solution. For F-JNW solution, $σ_l(ω)$ monotonically increases with the increase of $a(b)$ for fixed $b(a)$.

description: Coupling quantum emitters and nanostructures, in particular cold atoms and waveguides, has recently raised a large interest due to unprecedented possibilities of engineering light-matter interactions. However, the implementation of these promising concepts has been hampered by various theoretical and experimental issues. In this work, we propose a new type of periodic dielectric waveguide that provides strong interactions between atoms and guided photons with an unusual dispersion. We design an asymmetric comb waveguide that supports a slow mode with a quartic (instead of quadratic) dispersion and an electric field that extends far into the air cladding for an optimal interaction with atoms. We compute the optical trapping potential formed with two guided modes at frequencies detuned from the atomic transition. We show that cold Rubidium atoms can be trapped as close as 100 nm from the structure in a 1.3-mK-deep potential well. For atoms trapped at this position, the emission into guided photons is largely favored, with a beta factor as high as 0.88 and a radiative decay rate into the slow mode 10 times larger than the free-space decay rate.

description: The coherent superposition of states, in combination with the quantization of observables, represents one of the most fundamental features that mark the departure of quantum mechanics from the classical realm. Quantum coherence in many-body systems embodies the essence of entanglement and is an essential ingredient for a plethora of physical phenomena in quantum optics, quantum information, solid state physics, and nanoscale thermodynamics. In recent years, research on the presence and functional role of quantum coherence in biological systems has also attracted a considerable interest. Despite the fundamental importance of quantum coherence, the development of a rigorous theory of quantum coherence as a physical resource has only been initiated recently. In this Colloquium we discuss and review the development of this rapidly growing research field that encompasses the characterization, quantification, manipulation, dynamical evolution, and operational application of quantum coherence.

description: We propose a new program for computing a certain integrand of scattering amplitudes of four-dimensional gauge theories which we call the \textit{form factor integrand}, starting from 6d holomorphic theories on twistor space. We show that the form factor integrands can be expressed as sums of products of 1.) correlators of a 2d chiral algebra, related to the algebra of asymptotic symmetries uncovered recently in the celestial holography program, and 2.) OPE coefficients of a 4d non-unitary CFT. We prove that conformal blocks of the chiral algebras are in one-to-one correspondence with local operators in 4d. We use this bijection to recover the Parke-Taylor formula, the CSW formula, and certain one-loop scattering amplitudes. Along the way, we explain and derive various aspects of celestial holography, incorporating techniques from the twisted holography program such as Koszul duality. This perspective allows us to easily and efficiently recover the infinite-dimensional chiral algebras of asymptotic symmetries recently extracted from scattering amplitudes of massless gluons and gravitons in the celestial basis. We also compute some simple one-loop corrections to the chiral algebras and derive the three-dimensional bulk theories for which these 2d algebras furnish an algebra of boundary local operators.

description: In melanoma, immunocytology (IC) after sentinel lymph node disaggregation not only enables better quantification of disseminated cancer cells (DCCs) than routine histopathology (HP) but also provides a unique opportunity to detect, isolate, and analyse these earliest harbingers of metachronous metastasis. Here, we explored lymph node IC in non-small cell lung cancer (NSCLC). For 122 NSCLC patients, 220 lymph nodes (LNs) were split in half and prepared for IC and HP. When both methods were compared, IC identified 22% positive patients as opposed to 4.5% by HP, revealing a much higher sensitivity of IC (p < 0.001). Assessment of all available 2,952 LNs of the same patients by HP uncovered additional patients escaping detection of lymphatic tumour spread by IC alone, consistent with the concept of skip metastasis. A combined lymph node status of IC and complete HP on a larger cohort of patients outperformed all risk factors in multivariable analysis for prognosis (p < 0.001; RR = 2.290; CI 1.407-3.728). Moreover, isolation of DCCs and single-cell molecular characterization revealed that (1) LN-DCCs differ from primary tumours in terms of copy number alterations and selected mutations and (2) critical alterations are acquired during colony formation within LNs. We conclude that LN-IC in NSCLC patients when combined with HP improves diagnostic precision, has the potential to reduce total workload, and facilitates molecular characterization of lymphatically spread cancer cells, which may become key for the selection and development of novel systemic therapies.

description: We investigate a complex system involving multiple shapes to be optimized in a domain, taking into account geometric constraints on the shapes and uncertainty appearing in the physics. We connect the differential geometry of product shape manifolds with multi-shape calculus, which provides a novel framework for the handling of piecewise smooth shapes. This multi-shape calculus is applied to a shape optimization problem where shapes serve as obstacles in a system governed by steady state incompressible Navier--Stokes flow. Numerical experiments use our recently developed stochastic augmented Lagrangian method and we investigate the choice of algorithmic parameters using the example of this application.

description: Gravitational lensing in the weak field limit, quasinormal spectra, and gray-body factors are investigated in the Reissner-Nordström spacetime corrected by bounce parameters. Using the Gauss-Bonnet theorem, we analyze the effects of bounce corrections to the weak gravitational deflection angle and find that the divergence of the deflection angle can be suppressed by a bounce correction in the Reissner-Nordström spacetime. We also notice that the bounce correction plays the same role as the Morse potential in the deflection angle. Moreover, we derive the perturbation equations with the spin-dependent Regge-Wheeler potential and discuss the quasinormal spectral stability. We observe that the quasinormal spectra decrease for both the massless scalar and electromagnetic field perturbations. We further study the transmission probability of particles scattered by the Regge-Wheeler potential and reveal that the bounce correction introduced into the Reissner-Nordström spacetime increases the gray-body factors of perturbation fields.

description: We consider a self-avoiding walk on the $d$-dimensional hypercubic lattice, terminally attached to an impenetrable hyperplane at which it can adsorb. When a force is applied the walk can be pulled off the surface and we consider the situation where the force is applied at the middle vertex of the walk. We show that the temperature dependence of the critical force required for desorption differs from the corresponding value when the force is applied at the end-point of the walk. This is of interest in single molecule pulling experiments since it shows that the required force can depend on where the force is applied. We also briefly consider the situation when the force is applied at other interior vertices of the walk.

description: It has been reported in the literature that the survival probability $P(t)$ near an exceptional point where two eigenstates coalesce should generally exhibit an evolution $P(t) \sim t^2 e^{-Γt}$, in which $Γ$ is the decay rate of the coalesced eigenstate; this has been verified in a microwave billiard experiment [B. Dietz, et al, Phys. Rev. E 75, 027201 (2007)]. However, the heuristic effective Hamiltonian that is usually employed to obtain this result ignores the possible influence of the continuum threshold on the dynamics. By contrast, in this work we employ an analytical approach starting from the microscopic Hamiltonian representing two simple models in order to show that the continuum threshold has a strong influence on the dynamics near exceptional points in a variety of circumstances. To report our results, we divide the exceptional points in Hermitian open quantum systems into two cases: at an EP2A two virtual bound states coalesce before forming a resonance, anti-resonance pair with complex conjugate eigenvalues, while at an EP2B two resonances coalesce before forming two different resonances. For the EP2B, which is the case studied in the microwave billiard experiment, we verify the survival probability exhibits the previously reported modified exponential decay on intermediate timescales, but this is replaced with an inverse power law on very long timescales. Meanwhile, for the EP2A the influence from the continuum threshold is so strong that the evolution is non-exponential on all timescales and the heuristic approach fails completely. When the EP2A appears very near the threshold we obtain the novel evolution $P(t) \sim 1 - C_1 \sqrt{t} + D_1 t$ on intermediate timescales, while further away the parabolic decay (Zeno dynamics) on short timescales is enhanced. We also discuss the parametric encirclement of the EP2A in an appendix.

description: Short-range magnetic correlations can significantly increase the thermopower of magnetic semiconductors, representing a noteworthy development in the decades-long effort to develop high-performance thermoelectric materials. Here, we reveal the nature of the thermopower-enhancing magnetic correlations in the antiferromagnetic semiconductor MnTe. Using magnetic pair distribution function analysis of neutron scattering data, we obtain a detailed, real-space view of robust, nanometer-scale, antiferromagnetic correlations that persist into the paramagnetic phase above the Néel temperature $T_{\mathrm{N}}$ = 307 K. The magnetic correlation length in the paramagnetic state is significantly longer along the crystallographic $c$ axis than within the $ab$ plane, pointing to anisotropic magnetic interactions. Ab initio calculations of the spin-spin correlations using density functional theory in the disordered local moment approach reproduce this result with quantitative accuracy. These findings constitute the first real-space picture of short-range spin correlations in a magnetically enhanced thermoelectric and inform future efforts to optimize thermoelectric performance by magnetic means.

description: Coherent elastic neutrino-nucleus scattering (CEvNS) is a neutral-current process in which a neutrino scatters off an entire nucleus, depositing a tiny recoil energy. The process is important in core-collapse supernovae and also presents an opportunity for detection of a burst of core-collapse supernova neutrinos in low-threshold detectors designed for dark matter detection. Here we present an ongoing study of prospects for supernova burst detection via CEvNS in existing and future large-scale detectors. Presented at the 2019 Magnificent CEvNS workshop.

description: Untersuchungen zur Wirtschaftlichkeit der betrieblichen Prävention erfahren zunehmendes Interesse. Einerseits soll Unternehmen gezeigt werden, dass sich Betriebliches Gesundheitsmanagement rechnet. Andererseits sollen die durch Prävention vermeidbaren Kosten abgeschätzt und ggf. die kostengünstigsten Präventionsmaßnahmen identifiziert werden. Der ökonomische Nutzen von betrieblichem Gesundheitsmanagement gilt als wissenschaftlich eindrucksvoll belegt. Systematische Übersichtsarbeiten zeigen, dass sowohl die Krankheitskosten als auch die krankheitsbedingten Fehlzeiten um durchschnittlich 26% reduziert werden können. Auch die Abschätzung des allgemeinen ökonomischen Potenzials spricht für eine Intensivierung der betrieblichen Prävention. Durch arbeitsbedingte Erkrankungen entstehen in Deutschland jährliche Kosten in Höhe von insgesamt 44 Milliarden Euro. Davon entfallen 33 Milliarden Euro auf arbeitsbedingte Arbeitsunfähigkeit und 11 Milliarden Euro auf die arbeitsbedingte Frühberentung.

description: Silicon quantum dots are attractive candidates for the development of scalable, spin-based qubits. Pauli spin blockade in double quantum dots provides an efficient, temperature independent mechanism for qubit readout. Here we report on transport experiments in double gate nanowire transistors issued from a CMOS process on 300 mm silicon-on-insulator wafers. At low temperature the devices behave as two few-electron quantum dots in series. We observe signatures of Pauli spin blockade with a singlet-triplet splitting ranging from 0.3 to 1.3 meV. Magneto-transport measurements show that transitions which conserve spin are shown to be magnetic-field independent up to B = 6 T.

description: In this work we revisit itinerant ferromagnetism in 2D and 3D electron gases with arbitrary spin-orbit splitting and strong electron-electron interaction. We identify the resonant scattering processes close to the Fermi surface that are responsible for the instability of the ferromagnetic quantum critical point at low temperatures. In contrast to previous theoretical studies, we show that such processes cannot be fully suppressed even in presence of arbitrary spin-orbit splitting. A fully self-consistent non-perturbative treatment of the electron-electron interaction close to the phase transition shows that these resonant processes always destabilize the ferromagnetic quantum critical point and lead to a first-order phase transition. Characteristic signatures of these processes can be measured via the non-analytic dependence of the spin susceptibility on magnetic field both far away or close to the phase transition.
