Prediction of power losses in an automotive gearbox incorporating a thermally coupled lubrication model
Creators: name: Christodoulias, Athanasios
Publisher: name: Imperial College London
Year: 2017

description: The continuous tightening of environmental standards, and in particular the stricter vehicle CO2 emission regulations, have put increased pressure on passenger vehicle manufacturers to develop more efficient components. One way of improving fuel consumption and reducing emissions in a vehicle is by reducing the friction-related power loss in major components such as the engine and the transmission. Between 5% and 6% of the total fuel energy that the car converts is lost through friction in the transmission and ends up as heat being absorbed by the transmission lubricant. The principal aim of this project was developing a method to accurately predict power losses in the gearbox -the main transmission component- while at the same time having the ability to assess the influence of lubricant properties on the gearbox efficiency. For this purpose, a thermally coupled numerical model was developed, incorporating lubricant parameters extracted from rheological tests. The model calculates the friction coefficient in gear elastohydrodynamic (EHL) contacts and then uses it in an iterative scheme to predict in-contact and bulk temperatures as well as power losses. Finally, the model’s predictions for gears are coupled to current experimentally derived models for bearing and churning losses. The method has been applied to a single speed gearbox and a manual six speed automotive gearbox. Two fully formulated lubricants of nominally same specification were tested and comparisons were made for different input conditions and gear geometry changes. In the second case, a light duty truck fitted with the simulated gearbox has been instrumented and tested under different conditions. Temperature predictions from experimental drive cycles have been compared to model predictions and standardised drive cycles have also been simulated. Results show that the overall gear power loss is heavily dependent on the input torque and that the lambda ratio of the contact affects each component differently. In addition, the distribution of losses between gear friction, bearings and gear churning is not constant but depends on the selected components, the gear geometry, the surface roughness and the specific lubricant rheology. Furthermore, significant power loss differences of up to 11.7% and sump temperature differences of up to 3.1 °C respectively have been predicted between the two oils. Simulations of the six speed gearbox have shown that the model is able to predict bulk oil sump temperatures within 5-10% of measured values and can effectively be used to compare and rank different lubricants in terms of overall efficiency for a given gearbox.

description: This paper presents a novel VTOL UAV that owns a link connecting four rotors and a fuselage by a passive joint, allowing the control of the rotor's tilting angle by adjusting the rotors' thrust. This unique structure contributes to eliminating additional actuators, such as servo motors, to control the tilting angles of rotors, resulting in the UAV's weight lighter and simpler structure. We first derive the dynamical model of the newly designed UAV and analyze its controllability. Then, we design the controller that leverages the tiltable link with four rotors to accelerate the UAV while suppressing a deviation of the UAV's angle of attack from the desired value to restrain the change of the aerodynamic force. Finally, the validity of the proposed control strategy is evaluated in simulation study.
On the existence of brown dwarfs more massive than the hydrogen burning limit

description: Almost by definition brown dwarfs are objects with masses below the hydrogen burning limit, around $0.07\ M_\odot$. Below this mass, objects never reach a steady state where they can fuse hydrogen. Here we demonstrate, in contrast to this traditional view, that brown dwarfs with masses greater than the hydrogen burning limit may in principle exist in the universe. These objects, which we term "overmassive brown dwarfs" form a continuous sequence with traditional brown dwarfs in any property (mass, effective temperature, radius, luminosity). To form an overmassive brown dwarf, mass must be added sufficiently slowly to a sufficiently old traditional brown dwarf below the hydrogen burning limit. We identify mass transfer in binary brown dwarf systems via Roche lobe overflow driven by gravitational waves to be the most plausible mechanism to produce the bulk of the putative overmassive brown dwarf population.

Hubble Space Telescope Counts of Elliptical Galaxies: Constraints on Cosmological Models ?

description: The interpretation of galaxy number counts in terms of cosmological models is fraught with difficulty due to uncertainties in the overall galaxy population (mix of morphological types, luminosity functions etc.) and in the observations (loss of low surface brightness images, image blending etc.). Many of these can be overcome if we use deep high resolution imaging of a single class of high surface brightness galaxies, whose evolution is thought to be fairly well understood. This is now possible by selecting elliptical and S0 galaxies using Hubble Space Telescope images from the Medium Deep Survey and other ultradeep WFPC2 images. In the present paper, we examine whether such data can be used to discriminate between open and closed universes, or between conventional cosmological models and those dominated by a cosmological constant. We find, based on the currently available data, that unless elliptical galaxies undergo very strong merging since $z \sim 1$ (and/or very large errors exist in the morphological classifications), then flat models dominated by a cosmological constant are ruled out. However, both an Einstein-de Sitter ($Ω_{0}=1$) model with standard passive stellar evolution and an open ($Ω_{0}=0.05$) model with no net evolution ({\it i.e.} cancelling stellar and dynamical evolution) predict virtually identical elliptical and S0 galaxy counts. Based on these findings and the recent reportings of $H_{o} \simeq 80$ km/s Mpc/s, we find that the maximum acceptable age of the universe is 13.3 Gyrs and a value of $\leq 9$ Gyrs favored. A flat---$Λ\neq 0$---universe is therefore {\it not} a viable solution to the $H_{o}$/globular cluster age problem.

Development of optical probes and redox-activated complexes as G-quadruplex binders
Creators: name: Bandeira Pedro De Farias, Stephane
Publisher: name: Imperial College London
Year: 2017

description: Guanine-rich oligonucleotides can form non-canonical secondary structures that are referred to as G-Quadruplex and are present not only in the telomeres but also in promotor regions of some oncogenes. Due to their biological relevance, G-Quadruplexes are attractive targets for small molecules design. The research presented in this thesis aimed (i) to design and synthesize for the first time a platinum(IV) salphen complex featuring two chlorides at the axial positions, which could be switched on/off upon reduction using bio-reducing agents, thus rendering a good G4 binder; (ii) to create a dyad system featuring a fluorescent NBD moiety and Ni salphen, in order to achieve fluorescence quenching of the NBD moiety in the absence of G-Quadruplex DNA, for an “on-off” effect; and (iii) to design a bimetallic complex, and to attempt its synthesis. The interaction between the metal complexes and G-quadruplex DNA was examined by means of circular dichroism (CD), fluorescence and UV-vis titrations.

description: In this paper, we introduce the notion of an admissible partition of a simplicial polyhedral fan and define the category of a partitioned fan as a generalisation of the $τ$-cluster morphism category of a finite-dimensional algebra. This establishes a complete lattice of categories around the $τ$-cluster morphism category, which is closely tied to the fan structure. We prove that the classifying spaces of these categories are cube complexes, which reduces the process of determining if they are $K(π,1)$ spaces to three sufficient conditions. We characterise when these conditions are satisfied for fans in $\mathbb{R}^2$ and prove that the first one, the existence of a certain faithful functor, is satisfied for hyperplane arrangements whose normal vectors lie in the positive orthant. As a consequence we obtain a new infinite class of algebras for which the $τ$-cluster morphism category admits a faithful functor and for which the cube complexes are $K(π,1)$ spaces. In the final section we also offer a new algebraic proof of the relationship between an algebra and its $g$-vector fan.

Plasma Ejection from Magnetic Flares and the X-ray Spectrum of Cygnus X-1

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: The hard X-rays in Cyg X-1 and similar black hole sources are possibly produced in an active corona atop an accretion disk. We suggest that the observed weakness of X-ray reflection from the disk is due to bulk motion of the emitting hot plasma away from the reflector. A mildly relativistic motion causes aberration reducing X-ray emission towards the disk. This in turn reduces the reprocessed radiation from the disk and leads to a hard spectrum of the X-ray source. The resulting spectral index is Gamma=1.9B^{1/2} where B=gamma(1+beta) is the aberration factor for a bulk velocity beta=v/c. The observed Gamma=1.6 and the amount of reflection, R=0.3, in Cyg X-1 in the hard state can both be explained assuming a bulk velocity beta=0.3. We discuss one possible scenario: the compact magnetic flares are dominated by e+- pairs which are ejected away from the reflector by the pressure of the reflected radiation. We also discuss physical constraints on the disk-corona model and argue that the magnetic flares are related to magneto-rotational instabilities in the accretion disk.

description: In recent years, remarkable advances in photonic computing have highlighted the need for photonic memory, particularly high-speed and coherent random-access memory. Addressing the ongoing challenge of implementing photonic memories is required to fully harness the potential of photonic computing. A photonic-phononic memory based on stimulated Brillouin scattering is a possible solution as it coherently transfers optical information into sound waves at high-speed access times. Such an optoacoustic memory has shown great potential as it fulfils key requirements for high-performance optical random-access memory due to its coherence, on-chip compatibility, frequency selectivity, and high bandwidth. However, the storage time has so far been limited to a few nanoseconds due to the nanosecond decay of the acoustic wave. In this work, we experimentally enhance the intrinsic storage time of an optoacoustic memory by more than one order of magnitude and coherently retrieve optical information after a storage time of 120 ns. This is achieved by employing the optoacoustic memory in a highly nonlinear fiber at 4.2 K, increasing the intrinsic phonon lifetime by a factor of six. We demonstrate the capability of our scheme by measuring the initial and readout optical data pulse with a direct and double homodyne detection scheme. Finally, we analyze the dynamics of the optoacoustic memory at different cryogenic temperatures in the range of 4.2 K to 20 K and compare the findings to continuous wave measurements. The extended storage time is not only beneficial for photonic computing, but also for Brillouin applications that require long phonon lifetimes, such as optoacoustic filters, true-time delay networks, and synthesizers in microwave photonics.

description: Particle-in-cell (PIC) simulations have shown that relativistic collisionless magnetic reconnection drives nonthermal particle acceleration (NTPA), potentially explaining high-energy (X-ray/$γ$-ray) synchrotron and/or inverse Compton (IC) radiation observed from various astrophysical sources. The radiation back-reaction force on radiating particles has been neglected in most of these simulations, even though radiative cooling considerably alters particle dynamics in many astrophysical environments where reconnection may be important. We present a radiative PIC study examining the effects of external IC cooling on the basic dynamics, NTPA, and radiative signatures of relativistic reconnection in pair plasmas. We find that, while the reconnection rate and overall dynamics are basically unchanged, IC cooling significantly influences NTPA: the particle spectra still show a hard power law (index $\geq -2$) as in nonradiative reconnection, but transition to a steeper power law that extends to a cooling-dependent cutoff. The steep power-law index fluctuates in time between roughly $-$3 and $-$5. The time-integrated photon spectra display corresponding power laws with indices $\approx -0.5$ and $\approx -1.1$, similar to those observed in hard X-ray spectra of accreting black holes.

Material modelling and design of hot-rolled and cold-formed steel structures
Creators: name: Yun, Xiang
Publisher: name: Imperial College London
Year: 2018

description: The material modelling and design of hot-rolled and cold-formed structural steel cross-sections are addressed in this thesis. Regarding the material modelling, constitutive equations that accurately represent the stress-strain response of hot-rolled and cold-formed steels have been developed and calibrated based on a large dataset of coupon test results collected from the global literature. The models are suitable for use in advanced numerical simulations and parametric studies. For the design of structural steel elements, a deformation based design approach named the Continuous Strength Method (CSM), which provides an alternative treatment to the conventional concept of cross-section classification adopted in current design specifications and enables a rational exploitation of strain hardening, has been extended to cover both hot-rolled and cold-formed steels. The CSM design proposals were underpinned by existing test results collected from the literature in conjunction with additional cross-section tests on stocky hot-rolled I-sections conducted in the present study and numerical results obtained from validated finite element models. The design of cross-sections in compression, bending and combined loading has been addressed. The new design approach has been shown to yield a higher level of accuracy and consistency compared with the current codified design methods, and the reliability of the proposed design approach has been confirmed by performing statistical analyses. This study promotes the CSM as a universal design approach that now covers the design of stainless steel, aluminium alloy and structural carbon steel cross-sections. Recommendations for future developments to the CSM has also been made.

description: Collective electronic fluctuations in correlated materials give rise to various important phenomena, such as existence of the charge ordering, superconductivity, Mott insulating and magnetic phases, plasmon and magnon modes, and other interesting features of such systems. Unfortunately, description of these correlation effects requires significant efforts, since they almost entirely rely on strong local and nonlocal electron-electron interactions. Some collective phenomena, such as magnetism, can be sufficiently described by a simple Heisenberg-like models that are formulated in terms of bosonic variables. This fact suggests that other many-body excitations can also be described by simple bosonic models in spirit of the Heisenberg theory. Here we derive an effective bosonic action for charge degrees of freedom for the extended Hubbard model and define a physical regime where the obtained action reduces to a classical Hamiltonian of an effective Ising model.

description: Brownian motion (BM) is pivotal in natural science for the stochastic motion of microscopic droplets. In this study, we investigate BM driven by thermal composition noise at sub-micro scales, where inter-molecular diffusion and surface tension both are significant. To address BM of microscopic droplets, we develop two stochastic multi-phase-field models coupled with the full Navier-Stokes equation, namely Allen-Cahn-Navier-Stokes (ACNS) and Cahn-Hilliard-Navier-Stokes (CHNS). Both models are validated against capillary wave theory; the Einstein's relation for the Brownian coefficient at thermodynamic equilibrium is recovered. Moreover, by adjusting the co-action of the diffusion, Marangoni effect, and viscous friction, two non-equilibrium phenomena are observed. (I) The droplet motion transits from the Brownian to Ballistic with increasing Marangoni effect which is emanated from the energy dissipation mechanism distinct from the conventional fluctuation-dissipation theorem. (II) The deterministic droplet motion is triggered by the noise induced non-uniform velocity field which leads to a novel droplet coalescence mechanism associated with the thermal noise.

description: This study explores the impact of several factors on a victims' responses during sexual assault and/or rape. Specifically, the relationship between self-protective measures taken and the victims age, race, social economic status and the victim-offender relationship were examined. The study utilized the 1995 rape subset of the 1992-1995 redesigned National Crime Victimization Survey. The sample consisted of 350 female rape and/or sexual assault victims. Findings suggest that the victim-offender relationship significantly effects victims' self-protective strategies. Victims of intimate-perpetrated assaults utilize more passive-verbal self-protective tactics. Implications for law enforcement efforts and future research are discussed.

description: The production of the radioactive isotopes $^{44}$Ti and $^{60}$Co in all types of supernovae is examined and compared to observational constraints including Galactic $γ$--ray surveys, measurements of the diffuse 511 keV radiation, $γ$--ray observations of Cas A, the late time light curve of SN 1987A, and isotopic anomalies found in silicon carbide grains in meteorites. The (revised) line flux from $^{44}$Ti decay in the Cas A supernova remnant reported by COMPTEL on the Compton Gamma-Ray Observatory is near the upper bound expected from our models. The necessary concurrent ejection of $^{56}$Ni would also imply that Cas A was a brighter supernova than previously thought unless extinction in the intervening matter was very large. Thus, if confirmed, the reported amount of $^{44}$Ti in Cas A provides very interesting constraints on both the supernova environment and its mechanism. The abundances of $^{44}$Ti and $^{60}$Co ejected by Type II supernovae are such that gamma-radiation from $^{44}$Ti decay SN 1987A could be detected by a future generation of gamma-ray telescopes and that the decay of $^{60}$Co might provide an interesting contribution to the late time light curve of SN 1987A and other Type II supernovae. To produce the solar $^{44}$Ca abundance and satisfy all the observational constraints, nature may prefer at least the occasional explosion of sub-Chandrasekhar mass white dwarfs as Type Ia supernovae. Depending on the escape fraction of positrons due to $^{56}$Co made in all kinds of Type Ia supernovae, a significant fraction of the steady state diffuse 511 keV emission may arise from the annihilation of positrons produced during the decay of $^{44}$Ti to $^{44}$Ca. The Ca and Ti isotopic anomalies in pre-solar grains confirm the production of $^{44}$Ti in supernovae and that

description: Sgr A East is a very prominent elongated shell structure surrounding (though off-centered from) the Galactic nucleus. Its energetics (~4x10^52 ergs), based on the power required to carve out the radio synchrotron remnant within the surrounding dense molecular cloud, appear to be extreme compared to the total energy (~10^51 ergs) released in a typical supernova (SN) explosion. Yet it shares several characteristics in common with SN remnants (SNRs), the most significant of which is the ~0.1-10 GeV gamma-ray spectrum measured by EGRET, if we associate the Galactic center source 2EGJ1746-2852 with this nonthermal shell. We here show that the highest-energy component in Sgr A East's spectrum, like that of SNRs, can be fitted with the gamma-rays produced in neutral pion decays. Further, we demonstrate in a self-consistent manner that the leptons released in the associated charged pion decays produce an e+e- distribution that can mimic a power-law with index ~3, like that inferred from the VLA data for this source. These relativistic electrons and positrons also radiate by bremsstrahlung, and inverse Compton scattering with the intense IR and UV fields from the nucleus. We show that the overall emissivity calculated in this way may account for Sgr A East's broadband spectrum ranging from GHz frequencies all the way to TeV energies, where Whipple has thus far set an upper limit to the flux corresponding to a 2.5-sigma signal above the noise.

We detect diffuse emission in three of these (27$^{+20}_{-14}$\%): we detect a radio mini-halo in ACT-CL J0022.2$-$0036 at $z=0.8$, making it the highest-redshift mini-halo known; we detect potential radio relic emission in ACT-CL J0014.9$-$0057 ($z=0.533$); and we confirm the presence of a radio halo in low-mass cluster ACT-CL J0256.5+0006, with flux density $S_{610} = 6.3\;\pm\;0.4$ mJy. We also detect residual diffuse emission in ACT-CL J0045.9$-$0152 ($z=0.545$), which we cannot conclusively classify. For systems lacking diffuse radio emission, we determine radio halo upper limits in two ways and find via survival analysis that these limits do not significantly affect radio power scaling relations. Several clusters with no diffuse emission detection are known or suspected mergers, based on archival X-ray and/or optical measures; given the limited sensitivity of our observations, deeper observations of these disturbed systems are required in order to rule out the presence of diffuse emission consistent with known scaling relations. In parallel with our diffuse emission results, we present catalogs of individual radio sources, including a few interesting extended sources. Our study represents the first step towards probing the occurrence of diffuse emission in high-redshift ($z\gtrsim0.5$) clusters, and serves as a pilot for statistical studies of larger cluster samples with the new radio telescopes available in the pre-SKA era.

description: To enhance flexibility and facilitate resource cooperation, a novel fully-decoupled radio access network (FD-RAN) architecture is proposed for 6G. However, the decoupling of uplink (UL) and downlink (DL) in FD-RAN makes the existing feedback mechanism ineffective. To this end, we propose an end-to-end data-driven MIMO solution without the conventional channel feedback procedure. Data-driven MIMO can alleviate the drawbacks of feedback including overheads and delay, and can provide customized precoding design for different BSs based on their historical channel data. It essentially learns a mapping from geolocation to MIMO transmission parameters. We first present a codebook-based approach, which selects transmission parameters from the statistics of discrete channel state information (CSI) values and utilizes integer interpolation for spatial inference. We further present a non-codebook-based approach, which 1) derives the optimal precoder from the singular value decomposition (SVD) of the channel; 2) utilizes variational autoencoder (VAE) to select the representative precoder from the latent Gaussian representations; and 3) exploits Gaussian process regression (GPR) to predict unknown precoders in the space domain. Extensive simulations are performed on a link-level 5G simulator using realistic ray-tracing channel data. The results demonstrate the effectiveness of data-driven MIMO, showcasing its potential for application in FD-RAN and 6G.
New initiators for the ring-opening polymerisation of lactones
Creators: name: Myers, Dominic William
Publisher: name: Imperial College London

description: This thesis describes the preparation of new yttrium and indium phosphasalen catalysts for the stereocontrolled ring-opening polymerisation of rac-lactide. Systematic ligand modification was performed by changing the size of the phosphine substituents, the identity of the central donor of the diimine bridge, and through increasing the steric bulk at the ortho and para phenolate positions. The coordination chemistry of the final complexes was then explored with full characterisation by multinuclear NMR spectroscopy, elemental analysis or high-resolution mass spectrometry, and in most cases, single crystal X-ray diffraction. Yttrium phosphasalen compounds were found to be active initiators for the ring-opening polymerisation of rac-lactide, affording moderately isotactic polymers. The level of stereocontrol was shown to be influenced by the nature of the phosphine substituents, the diimine bridge, and to a limited extent, the size of the ortho phenolate substituents. The stereocontrol was observed to change when the diimine bridge donor atom was changed, with an NH substituent yielding isotactic enchainment (Pi = 0.72) and an O donor yielding moderately heterotactic (Ps = 0.73) enchainment. Indium phosphasalen compounds were similarly active for ROP, affording isotactic polymers, with one exception, which afforded atactic PLA. The level of stereocontrol was found to correlate with the flexibility of the diimine bridge and largely by the size of the ortho phenolate substituents. In the best cases, highly isotactic polylactide was afforded (Pi = 0.87 at 298 K) concurrent with fast rates, showcasing one of the best performing initiators in the stereocontrolled ring-opening polymerisation of raclactide. Finally, an yttrium phosphasalen complex was applied for the ring-opening polymerisation of three large macrolactones: ω-pentadecalactone (C15), ω-nonadecalactone (C19) and ω- tricosalactone (C23). A comparison is made between yttrium phosphasalen and aluminium salen complexes as initiators for these monomers, showing that with the former, higher rates (minute vs. hour timescales) are observed. The polymerisations of macrolactones are generally more challenging as they are entropically driven, hence the thermodynamic parameters are also uncovered, showing that high conversions (near-quantitative) remain feasible, with molecular weights up to 32 kg mol-1, even using ring sizes up to C23.

Neutrino sparking and the neutron to strange stars conversion

description: We address the production of strangelets inside neutron stars by means of high-energy neutrino interactions (sparking). Requiring that neutron stars remain as such along their lifetimes, we obtain a bound on the probability of a strangelet in the final state and compare it with existing laboratory limits. It turns out that this mechanism is not likely to drive a neutron $\to$ strange stars conversion for realistic values of the minimum center-mass-energy necessary to produce the quark-gluon plasma, a necessary precondition for the formation of the strangelet.

description: Crowdtesting is effective especially when it comes to the feedback on GUI systems, or subjective opinions about features. Despite of this, we find crowdtesting reports are highly replicated, i.e., 82% of them are replicates of others. Hence automatically detecting replicate reports could help reduce triaging efforts. Most of the existing approaches mainly adopted textual information for replicate detection, and suffered from low accuracy because of the expression gap. Our observation on real industrial crowdtesting data found that when dealing with crowdtesting reports of GUI systems, the reports would accompanied with images, i.e., the screenshots of the app. We assume the screenshot to be valuable for replicate crowdtesting report detection because it reflects the real scenario of the failure and is not affected by the variety of natural languages. In this work, we propose a replicate detection approach, TSDetector, which combines information from the screenshots and the textual descriptions to detect replicate crowdtesting reports. We extract four types of features to characterize the screenshots and the textual descriptions, and design an algorithm to detect replicates based on four similarity scores derived from the four different features respectively. We investigate the effectiveness and advantage of TSDetector on 15 commercial projects with 4,172 reports from one of the Chinese largest crowdtesting platforms.Results show that TSDetector can outperform existing state-of-the-art approaches significantly. In addition, we also evaluate its usefulness using real-world case studies. The feedback from real-world testers demonstrates its practical value

Design of adsorption systems by topology optimisation
Creators: name: Roman Amigo, Ricardo Cesare
Publisher: name: Imperial College London
Year: 2018

description: Adsorption is a retention mechanism of fluid molecules on solid surfaces and presents a wide range of applications, such as refrigeration, separation processes and fuel storage. This work describes the modelling of gas adsorption on porous media and presents an optimisation approach for the design of adsorption systems based on topology optimisation. A comprehensive formulation for the adsorption and desorption phenomena is presented, detailing the derivation of their weak forms and assembling the matrices for the implementation of the Finite Element Method (FEM). The sensitivities of objective functions to topology optimisation design variables are obtained by the adjoint method, which is presented in detail. The numerical implementation is aided by FEniCS and Dolfin Adjoint packages, resulting in a generic software for the optimisation of adsorption systems. The method is applied for the design of Adsorbed Natural Gas (ANG) tanks for on-demand consumption. Optimised tank layouts are proposed and compared with standard tanks, presenting improvement of the design objectives.

Discommensuration-enhanced superconductivity in the charge density wave phases of transition-metal dichalcogenides

description: We introduce a McMillan-Ginzburg-Landau theory to describe the cooperative coexistence of charge-density and superconducting order in two-dimensional crystals. With a free-energy that explicitly accounts for the competition between commensurate and incommensurate ground states, we are able to map the transition between these phases and monitor the development of discommensurations in the near-commensurate regime. Attributing the enhancement of superconducting order to density-wave fluctuations, we propose a coupling scheme that yields a phase diagram in qualitative agreement with experiments in conducting transition metal dichalcogenides. The model predicts the development of non-uniform superconductivity similar to that arising from a pair-density wave, with a spatial texture driven by the underlying charge-density wave fluctuations.
