description: In this paper, we introduce a novel solution to the covariant Landau equation for a pure electron plasma. The method conserves energy and particle number, and reduces smoothly to the Rosenbluth potentials of non-relativistic theory. In addition, we find that a fully relativistic plasma equilibrates in only 1/100th of a Spitzer time--much faster than in the non-relativistic limit--a factor of significant import to situations in which distortions to a Maxwellian distribution are produced by anomalous methods of acceleration. To demonstrate the power of our solution in dealing with hot, astrophysical plasmas, we use this technique to show that one of the currently considered models--continuous stochastic acceleration--for the hard X-ray emission in the Coma cluster actually cannot work because the energy gained by the particles is distributed to the {\it whole} plasma on a time scale much shorter than that of the acceleration process itself.

description: Dissipative particle dynamics (DPD) is a novel particle method for mesoscale modeling of complex fluids. DPD particles are often thought to represent packets of real atoms, and the physical scale probed in DPD models are determined by the mapping of DPD variables to the corresponding physical quantities. However, the non-uniqueness of such mapping has led to difficulties in setting up simulations to mimic real systems and in interpreting results. For modeling transport phenomena where thermal fluctuations are important (e.g., fluctuating hydrodynamics), an area particularly suited for DPD method, we propose that DPD fluid particles should be viewed as only 1) to provide a medium in which the momentum and energy are transferred according to the hydrodynamic laws and 2) to provide objects immersed in the DPD fluids the proper random "kicks" such that these objects exhibit correct fluctuation behaviors at the macroscopic scale. We show that, in such a case, the choice of system temperature and mapping of DPD scales to physical scales are uniquely determined by the level of coarse-graining and properties of DPD fluids. We also verified that DPD simulation can reproduce the macroscopic effects of thermal fluctuation in particulate suspension by showing that the Brownian diffusion of solid particles can be computed in DPD simulations with good accuracy.

description: Neutrinos drive core-collapse supernovae, launch outflows from neutron star merger accretion disks, and set the ratio of protons to neutrons in ejecta from both systems that generate heavy elements in the universe. Neutrinos of different flavors interact with matter differently, and much recent work has suggested that fast flavor instabilities are likely ubiquitous in both systems, but the final flavor content after the instability saturates has not been well understood. In this work we present particle-in-cell calculations which follow the evolution of all flavors of neutrinos and antineutrinos through saturation and kinematic decoherence. We conduct one-dimensional three-flavor simulations of neutrino quantum kinetics to demonstrate the outcome of this instability in a few example cases. We demonstrate the growth of both axially symmetric and asymmetric modes whose wavelength and growth rate match predictions from linear stability analysis. Finally, we vary the number density, flux magnitude, and flux direction of the neutrinos and antineutrinos and demonstrate that these factors modify both the growth rate and post-saturation neutrino flavor abundances. Weak electron lepton number (ELN) crossings in these simulations produce both slow growth of the instability and little difference between the flavor abundances in the initial and final states. In all of these calculations the same number of neutrinos and antineutrinos change flavor, making the least abundant between them the limiting factor for post-saturation flavor change. Many more simulations and multi-dimensional simulations are needed to fully probe the parameter space of the initial conditions.

description: We discuss the coarse-grained level density of the Hénon-Heiles system above the barrier energy, where the system is nearly chaotic. We use periodic orbit theory to approximate its oscillating part semiclassically via Gutzwiller's semiclassical trace formula (extended by uniform approximations for the contributions of bifurcating orbits). Including only a few stable and unstable orbits, we reproduce the quantum-mechanical density of states very accurately. We also present a perturbative calculation of the stabilities of two infinite series of orbits (R$_n$ and L$_m$), emanating from the shortest librating straight-line orbit (A) in a bifurcation cascade just below the barrier, which at the barrier have two common asymptotic Lyapunov exponents $χ_{\rm R}$ and $χ_{\rm L}$.

description: Parametrically tuning the oscillation dynamics of coupled micro/nano-mechanical resonators through a mechanical pump scheme has recently attracted great attentions from fundamental physics to various applications. However, the special design of the coupled resonators and low dissipation operation conditions significantly restrict the wide application of this tuning technique. In this study, we will show that, under ambient conditions, mechanical pump can parametrically control the oscillation dynamics in a single commercial microcantilever resonator. A strong phonon-cavity coupling with cooperativity up to ~398 and normal-mode splitting are observed in the microcantilever. The strong parametric interaction of the phonon-cavity coupling enables using mechanical pump to achieve a 43 dB (3 dB) parametric amplification (cooling). By utilizing mechanical pump, the force sensitivity and signal-to-noise ratio of the frequency-modulation Kelvin Probe Force Microscopy can be significantly improved in the ambient environment. Furthermore, both single-mode and two-mode thermomechanical noise squeezing states can be created in the microcantilever via applying mechanical pump.

description: Purely baryonic dark matter dominated models like MOND based on modification of Newtonian gravity have been successfully in reproducing some dynamical properties of galaxies. More recently, a relativistic formulation of MOND proposed by Bekenstein seems to agree with cosmological large scale structure formation. In this work, we revise the agreement of MOND with observations in light of the new results on the Cosmic Microwave Anisotropies provided by the 2003 flight of Boomerang. The measurements of the height of the third acoustic peak, provided by several small scale CMB experiments have reached enough sensitivity to severely constrain models without cold dark matter. Assuming that acoustic peak structure in the CMB is unchanged and that local measurements of the Hubble constant can be applied, we find that the cold dark matter is strongly favoured with Bayesian probability ratio of about one in two hundred.

Spin Seebeck Effect in Nonmagnetic Excitonic Insulators

description: We propose a mechanism of the spin Seebeck effect attributed to excitonic condensation in a nonmagnetic insulator. We analyze a half-filled two-orbital Hubbard model with a crystalline field splitting in the strong coupling limit. In this model, the competition between the crystalline field and electron correlations brings about an excitonic insulating state, where the two orbitals are spontaneously hybridized. Using the generalized spin-wave theory and Boltzmann transport equation, we find that a spin current generated by a thermal gradient is observed in the excitonic insulating state without magnetic fields. The spin Seebeck effect originates from spin-split collective excitation modes although the ground state does not exhibit any magnetic orderings. This peculiar phenomenon is inherent in the excitonic insulating state, whose order parameter is time-reversal odd and yields a spin splitting for the collective excitation modes. We also find that the spin current is strongly enhanced and its direction is inverted in the vicinity of the phase transition to another magnetically ordered phase. We suggest that the present phenomenon is possibly observed in perovskite cobaltites with the GdFeO$_3$-type lattice distortion.

description: General flavor changing interactions for a Goldstone boson (GB) to fermions due to a spontaneous global $U(1)_G$ symmetry breaking are discussed. This GB may be the Axion, solving the strong QCD CP problem, if there is a QCD anomaly for the $U(1)_G$ charge assignments for quarks. Or it may be the Majoron in models from lepton number violation in producing seesaw Majorana neutrino masses if the symmetry breaking scale is much higher than the electroweak scale. It may also, in principle, play the roles of Axion and Majoron simultaneously as far as providing solution for the strong CP problem and generating a small Majorana neutrino masses are concerned. Great attentions have been focused on flavor conserving GB interactions. Recently flavor changing Axion and Majoron models have been studied in the hope to find new physics from rare decays in the intensity frontier. In this work, we will provide a systematic model building aspect study for a GB having flavor changing neutral current (FCNC) interactions in both the quark and lepton sectors, or separately in the quark, charged lepton and neutrino sectors with sources of FCNC interactions identified in detail. We provide a general proof of the equivalence of using physical GB components and GB broken generators for calculating GB couplings to two gluons and two photons, and some issues related to models having spontaneous CP violation are discussed. We will also provide some details for obtaining FCNC GB interactions in several popular models, such as the Type-I, -II, -III seesaw and Left-Right symmetric models, and point out some special features in these models.

description: Recently, it has been proposed that higher-spin analogues of the Kitaev interactions $K>0$ may also occur in a number of materials with strong Hund's and spin-orbit coupling. In this work, we use Lanczos diagonalization and density matrix renormalization group methods to investigate numerically the $S=1$ Kitaev-Heisenberg model. The ground-state phase diagram and quantum phase transitions are investigated by employing local and nonlocal spin correlations. We identified two ordered phases at negative Heisenberg coupling $J<0$: a~ferromagnetic phase with $\langle S_i^zS_{i+1}^z\rangle>0$ and an intermediate left-left-right-right phase with $\langle S_i^xS_{i+1}^x\rangle\neq 0$. A~quantum spin liquid is stable near the Kitaev limit, while a topological Haldane phase is found for $J>0$.

Extended improvisations in the drumming of Max Roach and Kofi Ghanaba: rhythmic correspondences
Creators: name: Morris, Alex
Publisher: name: No Publisher Supplied
Year: 2021

description: The Ghanaian drummer Kofi Ghanaba is not frequently discussed as a central figure in the historical trajectory of modern jazz drumming. However, the nature of his musical relationship with the firmly influential Max Roach implies that Ghanaba may have had an important impact on the vocabulary of the jazz drumset. This thesis, using historiographic and analytical material, attempts to show the specific transference of musical data and concept from Ghanaba to Roach, thus re-orienting Kofi Ghanaba as a significant figure in the evolution of 20th-century jazz drumming.Historiographic and analytical methodology can help us to surmount the problems inherent to attempts at defining influence when there is an absence of verifiable primary-source testimony. The identification of a relevant temporal period and the use of transcription and analysis to comprehensively search for instances of “individual rhythmic correspondence” between Roach and Ghanaba is referred to using the metaphor of building an historiographic “sandbox,” through which we drag an analytical “comb.”Section I uses historical documents to establish proof of the physical and aural relationship between Roach and Ghanaba. Section II draws on existing research, my own comprehensive discographical exploration, and transcription and analysis to narrow down the possibilities of “individual rhythmic correspondence” between the two drummers. The use of complex ostinatos in long-form individual improvisations emerges as the most likely point of transference from Ghanaba to Roach.There are inherent historiographical difficulties in tracing point-to-point musical transference that can make proving lines of influence between artists an exceedingly murky endeavor. However, the significant documentation of physical and aural proximity, primary source confirmation of musical influence from both subjects, and concrete musical correlations supported by transcription and analysis suggest a firm basis for understanding Kofi Ghanaba as an influence on Max Roach, and, by extension, on the continuum of 20th-century jazz drumming.

description: Most modern wear resistant materials feature a multiphase microstructure and the macroscopic
wear behavior is controlled by the local mechanical properties of the single phases. Indentation
testing and in particular nanoindentation allows for the local mechanical characterization of
materials and their phases. This paper addresses the determination of important mechanical
parameters such as hardness, Young’s modulus and indentation energy parameters of single
phases in multiphase wear resistant materials. Important influencing factors such as matrix
influence on the indentation results of an embedded hard phase, the indentation-size-effect (ISE),
the effect of crystallographic orientation, and the fracturing behavior of hard phases are addressed.
In addition, the results of scratch tests on the cold work tool steel X210Cr12 and a WC-Co hard
metal are presented in order to investigate aspects of the mechanical behavior under abrasion.
The deformation behavior under indentation and scratch loading was analyzed by scanning
electron microscopy (SEM) and atomic force microscopy (AFM). Besides the experiments
supplementary numerical simulations of indentation and scratching testing with the use of the
Finite-Element-Method (FEM) are presented.

description: In this study, the Fe-C-B system is used as a basis for alloy development of tool steels. Thereby,
boron is used as hard phase forming element. The effect of chromium on the phase stability,
microstructure and hard phase properties of Fe-C-B-Cr alloys is investigated. In this manner,
thermodynamic equilibrium calculations are performed and experimentally validated. Laboratory
alloys were casted and investigated using scanning electron microscopy (SEM), energy dispersive
spectroscopy (EDS) and electron backscatter diffraction (EBSD). Nanoindentation was performed
to investigate the effect of Cr on the micromechanical properties of the particular hard phases
(elastic modulus and indentation hardness). It is shown, that Cr stabilizes the orthorhombic, Cr-rich
M2B type boride with a hardness of 22.8 GPa. In addition Cr stabilizes the Cr-rich M23(C,B)6
carboboride, which possess a lower hardness (14 GPa). In a next step, the findings are
implemented in an alloy development and alloying additions of chromium, silicon and manganese
are used to specifically stabilize the M2B type boride with high Cr content to adjust a high hardness
of the M2B phase. Subsequently, a scratch test is performed to investigate the governing wear
mechanisms in the developed alloy.

description: In this paper we discuss the blackhole-string transition of the small Schwarzschild blackhole of $AdS_5 \times S^5$ using the AdS/CFT correspondence at finite temperature. The finite temperature gauge theory effective action, at weak {\it and} strong coupling, can be expressed entirely in terms of constant Polyakov lines which are $SU (N)$ matrices. In showing this we have taken into account that there are no Nambu-Goldstone modes associated with the fact that the 10 dimensional blackhole solution sits at a point in $S^5$. We show that the phase of the gauge theory in which the eigenvalue spectrum has a gap corresponds to supergravity saddle points in the bulk theory. We identify the third order $N = \infty$ phase transition with the blackhole-string transition. This singularity can be resolved using a double scaling limit in the transition region where the large N expansion is organized in terms of powers of $N^{-2/3}$. The $N = \infty$ transition now becomes a smooth crossover in terms of a renormalized string coupling constant, reflecting the physics of large but finite N. Multiply wound Polyakov lines condense in the crossover region. We also discuss the implications of our results for the resolution of the singularity of the Lorenztian section of the small Schwarzschild blackhole.

description: The presented study investigates the hardness and sliding wear behavior of cemented carbides
and high-speed tool steels at elevated temperatures. Therefore, experimental analysis focus on the
behavior and the microstructural changes of the aforementioned materials during sliding wear at
room temperature, 400°C, and 600°C. Investigations are performed with respect to materials
mechanical properties, which are represented by high temperature hardness measurements. As a
result a main output of this study is an overview about the interdependencies of the microstructure
and the high temperature hardness of tool materials (cemented carbides, high-speed steels).
Results show that the absolute value of the room temperature and the high temperature hardness
of cemented carbides are connected to the WC-carbide volume fraction. In contrast, the
development of the hardness with increasing temperature is mainly influenced by the volume
fraction and the characteristics of the binder matrix. In addition to the investigation of cemented
carbides, the hardness of HS 6-5-3 steel grade at elevated temperatures was investigated. The
value of the high temperature hardness of HS 6-5-3 high-speed steel is comparable to the
hardness of cemented carbide materials, having higher binder content of 30 vol.-%.The absolute
value and the temperature dependent course of the high temperature hardness of the high-speed
steel are further influenced by the applied heat-treatment. Moreover, detailed wear experiments
and microscopic analyses of the worn surfaces of selected materials are presented. These
investigations show the main differences between room temperature sliding wear and high
temperature sliding wear. In the systems studied, an increase in testing temperature leads to a
rapid decrease of friction and wear rate. Microscopic investigations reveal that, the reason for this
effect is the formation of a tribochemical wear layer at the surface of the wear bodies. This layer
suppresses direct metallic contact and changes the characteristics of the tribological system.
Discussed issues of high temperature sliding wear are the formation and stability of tribochemical
wear layers, their connection to and support by the bulk material as well as the fracturing and
damage of the layer-bulk-material compound.

In collisions at large impact parameters, hadronic interactions are not possible, and the ions interact through photon-ion and photon-photon collisions known as {\it ultra-peripheral collisions} (UPC). Hadron colliders like the Relativistic Heavy Ion Collider (RHIC), the Tevatron and the Large Hadron Collider (LHC) produce photonuclear and two-photon interactions at luminosities and energies beyond that accessible elsewhere; the LHC will reach a $γp$ energy ten times that of the Hadron-Electron Ring Accelerator (HERA). Reactions as diverse as the production of anti-hydrogen, photoproduction of the $ρ^0$, transmutation of lead into bismuth and excitation of collective nuclear resonances have already been studied. At the LHC, UPCs can study many types of `new physics.'

description: By modifying and calibrating an active vertex model to experiments, we have simulated numerically a confluent cellular monolayer spreading on an empty space and the collision of two monolayers of different cells in an antagonistic migration assay. Cells are subject to inertial forces and to active forces that try to align their velocities with those of neighboring ones. In agreement with experiments, spreading tests exhibit finger formation in the moving interfaces, swirls in the velocity field, and the polar order parameter and correlation and swirl lengths increase with time. Cells inside the tissue have smaller area than those at the interface, as observed in recent experiments. In antagonistic migration assays, a population of fluidlike Ras cells invades a population of wild type solidlike cells having shape parameters above and below the geometric critical value, respectively. Cell mixing or segregation depends on the junction tensions between different cells. We reproduce experimentally observed antagonistic migration assays by assuming that a fraction of cells favor mixing, the others segregation, and that these cells are randomly distributed in space. To characterize and compare the structure of interfaces between cell types or of interfaces of spreading cellular monolayers in an automatic manner, we apply topological data analysis to experimental data and to numerical simulations. We use time series of numerical simulation data to automatically group, track and classify advancing interfaces of cellular aggregates by means of bottleneck or Wasserstein distances of persistent homologies. These topological data analysis techniques are scalable and could be used in studies involving large amounts of data. Besides applications to wound healing and metastatic cancer, these studies are relevant for tissue engineering, biological effects of materials, tissue and organ regeneration.

description: Scintillating crystals are used for calorimetry in several high-energy physics experiments. For many of them, performance has to be ensured in very difficult operating conditions, like a high radiation environment and large particle fluxes, which place constraints on response and readout time. An overview is presented of the knowledge reached up to date, and of the newest achievements in the field, with particular attention given to the performance of Lead Tungstate crystals exposed to large particle fluxes.

description: Carbon nanotube field-effect transistors (CNT FETs) have been proposed as possible building blocks for future nano-electronics. But a challenge with CNT FETs is that they appear to randomly display varying amounts of hysteresis in their transfer characteristics. The hysteresis is often attributed to charge trapping in the dielectric layer between the nanotube and the gate. This study includes 94 CNT FET samples, providing an unprecedented basis for statistics on the hysteresis seen in five different CNT-gate configurations. We find that the memory effect can be controlled by carefully designing the gate dielectric in nm-thin layers. By using atomic layer depositions (ALD) of HfO$_{2}$ and TiO$_{2}$ in a triple-layer configuration, we achieve the first CNT FETs with consistent and narrowly distributed memory effects in their transfer characteristics.

Proton superconductivity in pasta phases in neutron star crusts

description: In the so-called pasta phases predicted to occur in neutron star crusts, protons are able to move easily over large distances because the nuclear matter regions are extended in space. Consequently, electrical currents can be carried by protons, an effect not possible in conventional crystalline matter with isolated nuclei. With emphasis on the so-called lasagna phase, which has sheet-like nuclei, we describe the magnetic properties of the pasta phases allowing for proton superconductivity. We predict that these phases will be Type II superconductors and we calculate the energy per unit length of a flux line, which is shown to be strongly anisotropic. If, as seems likely, the pasta structure is imperfect, flux lines will be pinned and matter will behave as a good electrical conductor and flux decay times will be long. We describe some possible astrophysical manifestations of our results.

description: We study neutralino sectors in extensions of the MSSM that dynamically generate the mu-term. The extra neutralino states are superpartners of the Higgs singlets and/or additional gauge bosons. The extended models may have distinct lightest neutralino properties which can have important influences on their phenomenology. We consider constraints on the lightest neutralino from LEP, Tevatron, and (g-2)_mu measurements and the relic density of the dark matter. The lightest neutralino can be extremely light and/or dominated by its singlino component which does not couple directly to SM particles except Higgs doublets.

description: Neutrino physics is traversing an exciting period, after the important discovery that neutrinos are massive particles, that has implications from high-energy physics to cosmology. A new method for the production of intense and pure neutrino beams has been proposed recently: the ``beta-beam''. It exploits boosted radioactive ions decaying through beta-decay. This novel concept has been the starting point for a new possible future facility. Its main goal is to address the crucial issue of the existence of CP violation in the lepton sector. Here we review the status and the recent developments with beta-beams. We discuss the original, the medium and high-energy scenarios as well as mono-chromatic neutrino beams produced through ion electron-capture. The issue of the degeneracies is mentioned. An overview of low energy beta-beams is also presented. These beams can be used to perform experiments of interest for nuclear structure, for the study of fundamental interactions and for nuclear astrophysics.
