description: With the eta-nucleon (eta N) interaction Lagrangian deduced from chiral perturbation theory, we study the possible eta-mesic nuclei in the framework of relativistic mean-field theory. The eta single-particle energies are sensitive to the eta N scattering length, and increase monotonically with the nucleon number A. If the scattering length is in the range of a^{eta N}=0.75-1.05 fm and the imaginary potential V_{0}-15 MeV, some discrete states of C, O and Ne eta bound states should be identified in experiments. However, when the scattering length a^{eta N}< 0.5 fm, or the imaginary potential V_{0} > 30 MeV, no discrete eta meson bound states could be observed in experiments.

description: Slow magnetoacoustic waves are routinely observed in astrophysical plasma systems such as the solar corona. As a slow wave propagates through a plasma, it modifies the equilibrium quantities of density, temperature, and magnetic field. In the corona and other plasma systems, the thermal equilibrium is comprised of a balance between continuous heating and cooling processes, the magnitudes of which vary with density, temperature and magnetic field. Thus the wave may induce a misbalance between these competing processes. Its back reaction on the wave has been shown to lead to dispersion, and amplification or damping, of the wave. In this work the importance of the effect of magnetic field in the rapid damping of slow waves in the solar corona by heating/cooling misbalance is evaluated and compared to the effects of thermal conduction. The two timescales characterising the effect of misbalance are derived and calculated for plasma systems with a range of typical coronal conditions. The predicted damping times of slow waves from thermal misbalance in the solar corona are found to be of the order of 10-100 minutes, coinciding with the wave periods and damping times observed. Moreover the slow wave damping by thermal misbalance is found to be comparable to the damping by field-aligned thermal conduction. We show that in the infinite field limit, the wave dynamics is insensitive to the dependence of the heating function on the magnetic field, and this approximation is found to be valid in the corona so long as the magnetic field strength is greater than 10G for quiescent loops and plumes and 100G for hot and dense loops. In summary thermal misbalance may damp slow magnetoacoustic waves rapidly in much of the corona, and its inclusion in our understanding of slow mode damping may resolve discrepancies between observations and theory relying on compressive viscosity and thermal conduction alone.

title: Active Cloaking and Waves in Structured Media
Creators: name: O'Neill, J
Publisher: name: University of Liverpool Repository
Year: 2016

description: This thesis presents a novel method for active cloaking problems involving finite defects embedded in thin elastic plates. We demonstrate the approach by considering several geometries and boundary conditions, which include circular geometries with clamped boundaries, circular shaped coated inclusions and a finite cluster of rigid pins. We use results from plate theory, including problems on scattering of flexural waves from canonical geometries and platonic crystals. Such systems are governed by the fourth-order biharmonic plate equation. The method employed involves surrounding an object with a configuration of active sources whose complex amplitudes are chosen such that the main contribution to the scattered wave is cancelled in the far field. The active sources are represented by the Green's function for the biharmonic operator, describing the response to a point force. This Green's function has the beneficial property of being non-singular at the origin and the approximate cloak leads to an analytical system of linear algebraic equations for calculating the amplitudes of the active sources, required for effective cloaking. We demonstrate that the method described is applicable to arbitrarily shaped scatterers; effective cloaking is presented for a scatterer with a smooth, clamped boundary. Cloaking is also demonstrated for a circular clamped inclusion subject to flexural waves generated by a remote point source. Studying this problem enables us to find a Green's function for the cloaking problem which can be used to cloak a discretely distributed time-harmonic load. The cloaking is shown to work well at lower frequency regimes, however, at higher frequency resonant regimes, rapid changes in scattering from the inclusion are observed in narrow frequency intervals. This makes the cloak vulnerable to detection using frequency swept probe beams; time lags can arise as the sources adapt to the alterations in frequency. We extend the approach to the case of a resonant inclusion, combining active and passive techniques to tame regions of rapid variation in scattering properties. We then apply the active cloaking method approach to the coated inclusion. Finally, we modify the method for cloaking finite clusters of pins, where the geometry of the cluster causes interactions between the evanescent terms of solutions to the biharmonic equation, leading to interesting scattering patterns. Our method of active cloaking in thin elastic plates is shown to work for scattering phenomena such as localisation, wave-trapping and neutrality. We analyse band diagrams and dispersion surfaces from the infinite structure to estimate frequencies at which these phenomena occur in the finite cluster, and demonstrate effective cloaking using a finite number of sources.

description: The unprecedented amount and the excellent quality of lensing data that the upcoming ground- and space-based surveys will produce represent a great opportunity to shed light on the questions that still remain unanswered concerning our universe and the validity of the standard $Λ$CDM cosmological model. Therefore, it is important to develop new techniques that can exploit the huge quantity of data that future observations will give us access to in the most effective way possible. For this reason, we decided to investigate the development of a new method to treat weak lensing higher order statistics, which are known to break degeneracy among cosmological parameters thanks to their capability of probing the non-Gaussian properties of the shear field. In particular, the proposed method directly applies to the observed quantity, i.e., the noisy galaxy ellipticity. We produced simulated lensing maps with different sets of cosmological parameters and used them to measure higher order moments, Minkowski functionals, Betti numbers, and other statistics related to graph theory. This allowed us to construct datasets with different size, precision, and smoothing. We then applied several machine learning algorithms to determine which method best predicts the actual cosmological parameters associated with each simulation. The best model resulted to be simple multidimensional linear regression. We used this model to compare the results coming from the different datasets and found out that we can measure with good accuracy the majority of the parameters that we considered. We also investigated the relation between each higher order estimator and the different cosmological parameters for several signal-to-noise thresholds and redshifts bins. Given the promising results, we consider this approach as a valuable resource, worth of further development.

description: Knowledge of the Bs decay fraction of the Y(5S) resonance, fs, is important for Bs meson studies at the Y(5S) energy. Using a data sample collected by the CLEO III detector at CESR consisting of 0.423/fb on the Y(5S) resonance, 6.34/fb on the Y(4S) and 2.32/fb in the continuum below the Y(4S), we measure B(Y(5S) -> phi X)=(13.8 +/- 0.7 {+2.3}{-1.5})% and B(Y(4S) -> phi X) = (7.1 +/- 0.1 +/-0.6)%; the ratio of the two rates is (1.9 +/- 0.1 {+0.3}{-0.2}). This is the first measurement of the phi meson yield from the Y(5S). Using these rates, and a model dependent estimate of B(Bs -> phi X), we determine fs = (24.6 +/- 2.9 {+11.0}{-5.3})%. We also update our previous independent measurement of fs made using the inclusive Ds yields to now be (16.8 +/- 2.6 {+6.7}{-3.4)%, due to a better estimate of the number of hadronic events. We also report the total Y(5S) hadronic cross section above continuum to be sigma(e^+e^- -> Y(5S))=(0.301 +/- 0.002 +/- 0.039) nb. This allows us to extract the fraction of B mesons as (58.9+/-10.0+/-9.2)%, equal to 1-fs. averaging the three methods gives a model dependent result of fs=(21 {+6}{-3})%.

description: We fabricated Pt/NiO/Pt capacitor structures with various bottom electrode thicknesses, $t_{BE}$, and investigated their resistance switching behaviors. The capacitors with $t_{BE} \geq 50$ nm exhibited typical unipolar resistance memory switching, while those with $t_{BE} \leq 30$ nm showed threshold switching. This interesting phenomenon can be explained in terms of the temperature-dependent stability of conducting filaments. In particular, the thinner $t_{BE}$ makes dissipation of Joule heat less efficient, so the filaments will be at a higher temperature and become less stable. This study demonstrates the importance of heat dissipation in resistance random access memory.

description: Large basis untruncated shell model calculations have been done for the A=138 neutron -rich nuclei in the pi(gdsh) X nu(hfpi) valence space above the 132Sn core. Two (1+2) -body nuclear Hamiltonians, viz., realistic CWG and empirical SMPN in this model space have been used. Calculated ground state binding energies, level spectra and other spectroscopic properties have been compared with the available experimental data. Importance of untruncated shell model calculations in this model space has been pointed out. Shell model results for the very neutron rich Sn isotope (138Sn, N/Z=1.76) of astrophysical interest for which no spectroscopic information except beta -decay half life is available, have been presented. Shell structure and evolution of collectivity in the even-even A=138 isobars have been studied as a function of valence neutron and /or proton numbers. Calculations done for the first time, reproduce remarkably well the collective vibrational states in 138Te and 138Xe. Comparison of some of the important two-body matrix elements of the empirical SMPN, CW5082 and the realistic CWG interactions has been done. These matrix elements are important for ground state binding energies and low-lying spectra of nuclei in this region. Consideration of the predictability of the two interactions seems to suggest that, in order to incorporate the special features of the N-N interaction in such exotic n-rich environment above the 132Sn core, the use of local spectroscopic information from the region might be essential.

description: We study a two-dimensional single band Hubbard Hamiltonian with antisymmetric spin-orbit coupling. We argue that this is the minimal model to understand the electronic properties of locally non-centrosymmetric transition-metal (TM) oxides such as Sr$_2$IrO$_4$. Based on exact diagonalizations of small clusters and the random phase approximation, we investigate the correlation effects on charge and magnetic order as a function of doping and of the TM-oxygen-TM bond angle $θ$. For small doping and $θ$ $\lesssim$ $15^\circ$ we find dominant commensurate in-plane antiferromagnetic fluctuations while ferromagnetic fluctuations dominate for $θ$ $\gtrsim$ $25^\circ$. Moderately strong nearest-neighbor Hubbard interactions can also stabilize a charge density wave order. Furthermore, we compare the dispersion of magnetic excitations for the hole-doped case to resonant inelastic X-ray scattering data and find good qualitative agreement.

description: $f(R)$-theories of gravity are reviewed in the context of the so called gravitational baryogenesis. The latter is a mechanism for generating the baryon asymmetry in the Universe, and relies on the coupling between the Ricci scalar curvature $R$ and the baryon current. Gravity Lagrangians of the form ${\cal L}(R)\sim R^n$, where $n$ differs from 1 (the case of the General Relativity) only for tiny deviations of a few percent, are consistent with the current bounds on the observed baryon asymmetry.

Molecular identification of ericoid mycorrhizal fungi
Creators: name: Monreal, Marcia Amelia
Publisher: name: University of British Columbia
Year: 2009

description: Molecular techniques facilitated the identification of ericoid mycorrhizal fungi associated with an ericaceous plant, salal (Gaultheria shallon Purch), dominant in some reforestation sites in the Canadian West Coast. The polymerase chain reaction (PCR) was used to amplify the DNA coding for the internal transcribed spacers (ITS1 and ITS2) of the nuclear ribosomal repeat of 28 fungal isolates. Restriction fragment length polymorphism (RFLP) patterns of these isolates obtained using a set of four restriction enzymes were compared and a synoptic key that differentiates these isolates into 14 groups was created. A fungal specific primer (ITS1-F) was used to amplify DNA of salal mycorrhizae obtained under axenic conditions with specific combinations of salal plants and fungal inoculum. Comparison among RFLP patterns of the fungal isolates with salal mycorrhizae showed that the fungal specific primer (ITS1-F) allowed the preferential amplification of the fungal component of the mycorrhizal association. RFLPs of fungal isolates and salal mycorrhizae were identical. Mycorrhizal root fragments from a salal plant were collected at a reforestation site on Vancouver Island. From one set of root fragments, DNA was extracted and amplified by PCR. Subsequent RFLP patterns obtained indicated the presence of a selection of various fungi. A second set of 5 m m mycorrhizal roots fragments were plated on Petri dishes and 20 fungal isolates were obtained. The in vitro capacity to form mycorrhizae with salal was tested for all isolates and only five were confirmed mycorrhizal with salal. Known RFLP patterns were detected from two new isolates: one matched the RFLP pattern produced by Oidiodendron species and the other matched a nonsporulating fungus (Unknown 2) described from previous work. The RFLP patterns of the other 18 newly isolated sterile fungi, including three isolates that formed in vitro mycorrhizae with salal, were different from those of all known ericoid mycorrhizal fungi. The fifteen new isolates that did not form ericoid mycorrhizae in vitro corresponded with seven RFLP patterns and their roles in association with salal roots is unknown. To create a method that would allow the direct assesment of the presence of known ericoid mycorrhizal fungi in salal roots collected from the field, the internal transcribed spacer ITS2 region and 3' end of the 5.8S rRNA gene (400 base pairs) of 24 fungal isolates were amplified and sequenced. Sequence data analysis segregated the mycorrhizal isolates into two main groups, one including species of Oidiodendron, and the second including Hymenoscyphus and allied taxa. Accordingly, three different specific primers were designed, the first to amplify Oidiodendron species, and the second and third, to identify clusters of isolates from the Hymenoscyphus group. Tests performed using the new primers with fungal DNA mixtures of known mycorrhizal isolates and nonmycorrhizal fungal isolates detected only the fungal DNA.

description: We present results of X-ray observations of the Coma cluster with multiple instruments over a broad energy band. Using the data from INTEGRAL, RXTE and ROSAT observatories, we find that the Coma spectrum in the 0.5-107 keV energy band can be well approximated by a thermal plasma emission model with a temperature of T=8.2 keV. INTEGRAL was used to image the cluster emission in the hard energy band. The cluster is only marginally detectable ~1.6sigma in the 44-107 keV energy band; however, the raw flux in this band is consistent with the previous results from Beppo-SAX and RXTE observatories. We can exclude with high significance that the hard-band flux reported by Beppo-SAX and RXTE could be produced by a single point source. The 20-80 keV flux of a possible non-thermal component in the cluster spectrum is (6.0+-8.8)*10**-12 ergs/cm^2/s. It is unlikely that the IC scattering of CMB photons is able to produce hard X-ray flux at these levels, unless the magnetic field strength is as low as 0.2muG. The latter value can be considered as a lower limit on the field strength in Coma. We also present a temperature map of the central part of the cluster, which shows significant variations and in particular, a hot, ~11.5 keV, region in the extension towards the subcluster infalling from the South-West.

description: Diffraction images with continuous rotation symmetry arise from amorphous systems, but also from regular crystals when investigated by powder diffraction. On the theoretical side, pinwheel patterns and their higher dimensional generalisations display such symmetries as well, in spite of being perfectly ordered. We present first steps and results towards a general frame to investigate such systems, with emphasis on statistical properties that are helpful to understand and compare the diffraction images. An alternative substitution rule for the pinwheel tiling, with two different prototiles, permits the derivation of several combinatorial and spectral properties of this still somewhat enigmatic example. These results are compared with properties of the square lattice and its powder diffraction.

description: (Abridged abstract) We explore the formation of ultra-massive (M_{\rm WD} \gtrsim 1.05 M_\sun$), carbon-oxygen core white dwarfs resulting from single stellar evolution. We also study their evolutionary and pulsational properties and compare them with those of the ultra-massive white dwarfs with oxygen-neon cores resulting from carbon burning in single progenitor stars, and with binary merger predictions. We consider two single-star evolution scenarios for the formation of ultra-massive carbon-oxygen core white dwarfs that involve rotation of the degenerate core after core helium burning and reduced mass-loss rates in massive asymptotic giant-branch stars. We compare our findings with the predictions from ultra-massive white dwarfs resulting from the merger of two equal-mass carbon-oxygen core white dwarfs, by assuming complete mixing between them and a carbon-oxygen core for the merged remnant. The resulting ultra-massive carbon-oxygen core white dwarfs evolve markedly slower than their oxygen-neon counterparts. Our study strongly suggests the formation of ultra-massive white dwarfs with carbon-oxygen core from single stellar evolution. We find that both the evolutionary and pulsation properties of these white dwarfs are markedly different from those of their oxygen-neon core counterparts and from those white dwarfs with carbon-oxygen core that might result from double degenerate mergers. This can eventually be used to discern the core composition of ultra-massive white dwarfs and their formation scenario.

description: Superconducting Josephson junction qubits constitute the main current technology for many applications, including scalable quantum computers and thermal devices. Theoretical modeling of such systems is usually done within the two-level approximation. However, accurate theoretical modeling requires taking into account the influence of the higher excited states without limiting the system to the two-level qubit subspace. Here, we study the dynamics and control of a superconducting transmon using the numerically exact stochastic Liouville-von Neumann equation approach. We focus on the role of state leakage from the ideal two-level subspace for bath induced decay and single-qubit gate operations. We find significant short-time state leakage due to the strong coupling to the bath. We quantify the leakage errors in single-qubit gates and demonstrate their suppression with DRAG control for a five-level transmon in the presence of decoherence. Our results predict the limits of accuracy of the two-level approximation and possible intrinsic constraints in qubit dynamics and control for an experimentally relevant parameter set.

Moreover, it is shown that the tangency unfolds generically with respect to the family. This result together with some theorem in Viana, we detect strange attractors appeared arbitrarily close to the original element with the heterodimensional cycle.

description: The CGMF code implements the Hauser-Feshbach statistical nuclear reaction model to follow the de-excitation of fission fragments by successive emissions of prompt neutrons and $γ$ rays. The Monte Carlo technique is used to facilitate the analysis of complex distributions and correlations among the prompt fission observables. Starting from initial configurations for the fission fragments in mass, charge, kinetic energy, excitation energy, spin, and parity, $Y(A,Z,KE,U,J,π)$, CGMF samples neutron and $γ$-ray probability distributions at each stage of the decay process, conserving energy, spin and parity. Nuclear structure and reaction input data from the RIPL library are used to describe fission fragment properties and decay probabilities. Characteristics of prompt fission neutrons, prompt fission gamma rays, and independent fission yields can be studied consistently. Correlations in energy, angle and multiplicity among the emitted neutrons and $γ$ rays can be easily analyzed as a function of the emitting fragments.

description: There is growing evidence that the prevalence of disagreement in the raw annotations used to construct natural language inference datasets makes the common practice of aggregating those annotations to a single label problematic. We propose a generic method that allows one to skip the aggregation step and train on the raw annotations directly without subjecting the model to unwanted noise that can arise from annotator response biases. We demonstrate that this method, which generalizes the notion of a \textit{mixed effects model} by incorporating \textit{annotator random effects} into any existing neural model, improves performance over models that do not incorporate such effects.
Probing SUSY beyond the reach of LEP2 at the Fermilab Tevatron: low |M_3| dark matter models

description: In supersymmetric models where the magnitude of the GUT scale gaugino mass parameter M_3 is suppressed relative to M_1 and M_2, the lightest neutralino can be a mixed higgsino-bino state with a thermal relic abundance in agreement with the WMAP central value for Ω_{\rm CDM} h^2 and consistent with all other phenomenological constraints. In these models, the gluino can be as light as 200 GeV without conflicting with the LEP2 bounds on the chargino mass. Thus, gluino pair production can be accessible at the Fermilab Tevatron at high rates. In this framework, gluinos decay radiatively with a large branching fraction to a gluon plus a neutralino. We find that experiments at the Fermilab Tevatron, with 5 fb^{-1} of integrated luminosity, will be sensitive to gluino pair production in the m_{\tg}\sim 200-350 GeV range via the multi-jet +etmissing and multi-jet +\ell^+\ell^- + etmissing channels at the 5σlevel, while trilepton signatures are expected to be below this level of detectability. Dilepton mass edges from both \tz_2 and \tz_3 decays may be measurable in the dilepton + multi-jet +etmissing channel.

Sensation, perception, and imagery: a study of the Buddhist epistemology of perception with particular reference to the Tattvasamgraha and the Tattvasamgrahanjika
Creators: name: Coseru, Christian
Publisher: name: Canberra, ACT : The Australian National University
Year: 2004

description: This dissertation examines the theory of perception as reflected in the works of two influential Buddhist philosophers, Santarakita's Tattvasamgraha and its commentary by Kamalasila, the Tattvasamgrahapanjika (ca. 750-800 C.E.). In these two works, the authors advance the notion that perception ought to be regarded as the primary source of knowledge and be restricted only to that cognition which is devoid of conceptual thought and non-erroneous. Largely following a model provided by Dharmakirti (ca. 640 C.E.), Santaraksita and Kamalasila adopt two specific viewpoints in defining the perceptual aspects of knowledge: (i) the notion that the domains of language and conceptual thought are coextensive, which can be traced back to the grammarian-philosopher Bhartrhari (ca. 4-5th century C.E.); and (ii) a psychological perspective centred on the notion that direct, unmediated, perception is in fact possible, which finds its origins in the Abhidharma literature. For these Buddhist epistemologists, perception is not only a psychological process to be understood within the framework of classical Abhidharma psychology, but also an epistemic modality for establishing what counts as a valid source of knowledge. The authors' approach is to differentiate non-conceptual cognitions from the mass of cognitive events that is characteristic of ordinary, 'folk,' beliefs about the contents of experience. This differentiation resembles in many ways the methodology adopted by modern psychological investigations into the mechanism of perception and knowledge representation. Adopting a naturalist reading of epistemology, this dissertation argues that Buddhist philosophers did not make a radical distinction between epistemology and the psychological processes of cognition, at least not in the Western sense in which modern epistemology has drifted away from naturalist explanations. Proceeding though a detailed analysis of the textual material, this study concludes that the causal model of perceptual knowledge developed in the two works is intended to provide an empirical foundation for the Buddhist view that all phenomena arise in dependence upon a multitude of causes and conditions and are in a perpetual state of flux.

description: We compute the quark-gluon vertex in quenched lattice QCD, in the Landau gauge using an off-shell mean-field O(a)-improved fermion action. The Dirac-vector part of the vertex is computed for arbitrary kinematics. We find a substantial infrared enhancement of the interaction strength regardless of the kinematics.

description: We statistically study the relationship between the Lyman-alpha (\lya) and 1--8 Å soft X-ray (SXR) emissions from 658 M- and X-class solar flares observed by the {\em Geostationary Operational Environmental Satellite} during 2006--2016. Based on the peak times of the two waveband emissions, we divide the flares into three types. Type I (III) has an earlier (a later) peak time in the \lya\ emission than that in the SXR emission, while type II has nearly a same peak time (within the time resolution of 10 s) between the \lya\ and SXR emissions. In these 658 flares, we find that there are 505 (76.8\%) type I flares, 10 (1.5\%) type II flares, and 143 (21.7\%) type III flares, and that the three types appear to have no dependence on the flare duration, flare location, or solar cycle. Besides the main peak, the \lya\ emission of the three type flares also shows sub-peaks which can appear in the impulsive or gradual phase of the flare. It is found that the main-peak (for type I) and sub-peak (for type III) emissions of \lya\ that appear in the impulsive phase follow the Neupert effect in general. This indicates that such \lya\ emissions are related to the nonthermal electron beam heating. While the main-peak (for type III) and sub-peak (for type I) emissions of \lya\ that appear in the gradual phase are supposed to be primarily contributed by the thermal plasma that cools down.

description: Two Delone sets are called homometric when they share the same autocorrelation or Patterson measure. A model set LAMBDA within a given cut and project scheme is a Delone set that is defined through a window W in internal space. The autocorrelation measure of LAMBDA is a pure point measure whose coefficients can be calculated via the so-called covariogram of W. Two windows with the same covariogram thus result in homometric model sets. On the other hand, the inverse problem of determining LAMBDA from its diffraction image ultimately amounts to reconstructing W from its covariogram. This is also known as Matheron's covariogram problem. It is well studied in convex geometry, where certain uniqueness results have been obtained in recent years. However, for non-convex windows, uniqueness fails in a relevant way, so that interesting applications to the homometry problem emerge. We discuss this in a simple setting and show a planar example of distinct homometric model sets.

The Cosmological Constant as a Zero Action Boundary

description: The cosmological constant $Λ$ is usually interpreted as Dark Energy (DE) or modified gravity (MG). Here we propose instead that $Λ$ corresponds to a boundary term in the action of classical General Relativity. The action is zero for a perfect fluid solution and this fixes $Λ$ to the average density $ρ$ and pressure $p$ inside a primordial causal boundary: $Λ= 4πG $. This explains both why the observed value of $Λ$ is related to the matter density today and also why other contributions to $Λ$, such as DE or MG, do not produce cosmic expansion. Cosmic acceleration results from the repulsive boundary force that occurs when the expansion reaches the causal horizon. This universe is similar to the $Λ$CDM universe, except on the largest observable scales, where we expect departures from homogeneity/isotropy, such as CMB anomalies and variations in cosmological parameters indicated by recent observations.

Quantum walk on circles in phase space

description: We propose a variation of the quantum walk on a circle in phase space by conjoining the Hadamard coin flip with simultaneous displacement of the walker's location in phase space and show that this generalization is a proper quantum walk albeit over multiple concentric circles in phase instead of just over one circle. We motivate the conjoining of Hadamard and displacement operations by showing that the Jaynes-Cummings model for coin+walker approximately yields this description in the dispersive limit. The quantum walk signature is evident in the phase distribution of the walker provided that appropriate pulse durations are applied for each coin flip.

description: Photons and dileptons are being used to probe the properties of nuclear and quark-gluon matter at high energy densities. This is an area where theory and experiment are driving each other to obtain solid results. However, it is important to clearly separate the assumptions and conclusions concerning the correlation and response functions of a system in thermal equilibrium from the space-time dynamics used to model the evolution of the matter created in the nuclear collision.

Effect of pressure on the pseudogap and charge-density-wave phases of the cuprate La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$ probed by thermopower measurements

description: We report thermopower measurements under hydrostatic pressure on the cuprate superconductor La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$ (Nd-LSCO), at low-temperature in the normal state accessed by suppressing superconductivity with a magnetic field up to $H = 31$ T. Using a newly developed AC thermopower measurement technique suitable for high pressure and high field, we track the pressure evolution of the Seebeck coefficient $S$. At ambient pressure and low temperature, $S/T$ was recently found to suddenly increase in Nd-LSCO at the pseudogap critical doping $p^{\star} = 0.23$, consistent with a drop in carrier density $n$ from $n = 1 + p$ above $p^{\star}$ to $n = p$ below. Under a pressure of 2.0 GPa, we observe that this jump in $S/T$ is suppressed. This confirms a previous pressure study based on electrical resistivity and Hall effect which found $dp^{\star}/dP \simeq - 0.01$ holes/GPa, thereby reinforcing the interpretation that this effect is driven by the pressure-induced shift of the van Hove point. It implies that the pseudogap only exists when the Fermi surface is hole-like, which puts strong constraints on theories of the pseudogap phase. We also report thermopower measurements on Nd-LSCO and La$_{1.8-x}$Eu$_{0.2}$Sr$_x$CuO$_4$ in the charge density-wave phase near $p \sim 1/8$, which reveals a weakening of this phase under pressure.
