description: In this work, we address the question of the influence of magnetic islands on the perpendicular transport due to steady-state ITG turbulence on the energy transport time scale. We demonstrate that turbulence can cross the separatrix and enhance the perpendicular transport across magnetic islands. As the perpendicular transport in the interior of the island sets the critical island size needed for growth of neoclassical tearing modes, this increased transport leads to a critical island size larger than that predicted from considering collisional conductivities, but smaller than that using anomalous effective conductivities. We find that on Bohm time scales, the turbulence is able to re-establish the temperature gradient across the island for islands widths $w \lesssim λ_{turb}$, the turbulence correlation length. The reduction in the island flattening is estimated by comparison with simulations retaining only the perpendicular temperature and no turbulence. At intermediate island widths, comparable to $λ_{turb}$, turbulence is able to maintain finite temperature gradients across the island.

description: Background: Pauci-immune crescentic and necrotizing glomerulonephritis (GN) is the hallmark of ANCA associated GN, with renal medullary angiitis (RMA) involving vasa recta of the medulla reported infrequently. We sought to describe the clinico-pathologic characteristics and treatment outcomes of RMA in ANCA associated vasculitis (AAV) patients who underwent a diagnostic kidney biopsy. Methods:  A search was conducted in our renal pathology database to identify kidney biopsies in patients with AAV with a diagnosis of angiitis and medullary angiitis for the time period 2000-2021. RMA was defined by the presence of interstitial hemorrhage in the medulla associated with a polymorphonuclear leukocyte infiltrate and karyorrhectic debris. All retrieved cases were examined by a pathologist to confirm that the histologic criteria were met. Demographic, clinical and treatment details were extracted by record review. Descriptive statistics is used to describe the variables of interest. Results: Among 136 AAV biopsies, we identified 13 (~10%) cases of RMA. The median age was 71 years (range between 17 and 84), 7 (53%) were females, 6 (46%) cases had PR3 ANCA positive serology, and 9 (64%) cases had extra-renal manifestations. The mean (SD) entry eGFR was 16 (10) ml/min/m2, ESR 98 (33) mm/hr, serum albumin 2.9 (0.5) mg/dL, and proteinuria in 12 patients was 1.8 (1.8) grams. All biopsies included cortex with a mean (SD) of 9 (6) glomeruli, and 6 biopsies with less than 10 glomeruli. Global glomerulosclerosis beyond age adjusted was noted in 4 cases, and segmental glomerulosclerosis was noted in 2 cases. In 5 biopsies, cellular crescents were noted, and glomerular necrosis was appreciated in 8 biopsies. Majority had moderate to severe interstitial inflammation and mild tubulointerstitial scarring. Granulomatous reaction was noted in one biopsy. Four patients had arteritis involving small renal arteries. Most of the patients (71%) had extensive tubular injury. All patients were treated with pulse methylprednisone and prednisone taper in combination with cyclophosphamide (n=6), rituximab (n=7) and mycophenolate (n=1). During a mean (SD) follow up of 50 (58) months, 1 patient reached ESKD, 1 patient died and the mean (SD) eGFR at last follow up was 45 (21) ml/min/m2 in the remainder. Conclusion: RMA was seen in 10% of biopsies in our cohort and clinically presents with severely impaired renal function with elevated inflammatory markers. Acute lesions in the form of crescentic and necrotizing lesions and interstitial inflammation with less chronicity are observed in kidney biopsies with RMA. Despite severe presentation, majority of patients respond to immunosuppression with good recovery of renal function. Disclosures: None.

description: Despite the discovery of thousands of exoplanets, no exomoons have been detected so far. We test a recently developed method for exomoon search, the orbital sampling effect (OSE), using the full exoplanet photometry from the Kepler Space Telescope. The OSE is applied to phase-folded transits, for which we present a framework to detect false positives, and discuss four candidates which pass several of our tests. Using numerical simulations, we inject exomoon signals into real Kepler data and retrieve them, showing that under favorable conditions, exomoons can be found with Kepler and the OSE method. In addition, we super-stack a large sample of Kepler planets to search for the average exomoon OSE and the accompanying increase in noise, the scatter peak. We find a significant OSE-like signal, which might indicate the presence of moons, for planets with 35d

description: Background: Midwives are the largest workforce involved in caring for pregnant women and their babies, and are well placed to translate research into practice and ensure midwifery priorities are appropriately targeted in researched. Currently, the number and focus of randomised controlled trials led by midwives in Australia and New Zealand is unknown. The Australasian Nursing and Midwifery Clinical Trials Network was established in 2020 to build nursing and midwifery research capacity. To aid this, scoping reviews of the quality and quantity of nurse and midwife led trials were undertaken. Aim: To identify midwife led trials conducted between 2000 and 2021 in Australia and New Zealand. Methods: This review was informed by the JBI scoping review framework. Medline, Emcare, and Scopus were searched from 2000-August 2021. ANZCTR, NHMRC, MRFF, and HRC (NZ) registries were searched from inception to July 2021. Findings: Of 26,467 randomised controlled trials registered on the Australian and New Zealand Clinical Trials Registry, 50 midwife led trials, and 35 peer-reviewed publications were identified. Publications were of moderate to high quality with scores limited due to an inability to blind participants or clinicians. Blinding of assessors was included in 19 published trials. Discussion: Additional support for midwives to design and conduct trials and publish findings is required. Further support is needed to translate registration of trial protocols into peer reviewed publications. Conclusion: These findings will inform the Australasian Nursing and Midwifery Clinical Trials Network plans to promote quality midwife led trials.

description: The purpose of this Master’s project is to build a clearer picture of North Carolina’s flood resilience investments over the last 5 years. Through an analysis of the communities receiving direct funding through budgetary legislation between 2018-2022, this research supports the North Carolina Office of Recovery and Resiliency (NCORR) and its partners in their efforts to understand the impact of past state funding for flood resilience and to identify the remaining gaps in resources. This project encompasses maps of the existing investment landscape and utilized flood extent, National Risk Index, and rural capacity data to compare the spatial distribution of flood resilience investments and the communities most at risk of flood hazards and those with social and administrative vulnerabilities in need of investment. The analysis in this project identified mismatch in the communities who received funding for flood resilience and those with the great need for financial support, according to their flood risk, vulnerability, and rural capacity. Through this project, I have built a case for a more comprehensive tracking platform of state flood resilience investments and identified several avenues to continue this research.

description: We use our resummed quantum gravity approach to Einstein's general theory of relativity in the context of the Planck scale cosmology formulation of Bonanno and Reuter to estimate the value of the cosmological constant such that ρ_Λ=(0.0024 eV)^4. We argue that the closeness of this estimate to experiment constrains susy GUT models. We discuss in turn various theoretical issues that have been raised about the approach itself as well as about the application to estimate the cosmological constant. Given the closeness of the estimate to the currently observed value, we also discuss the theoretical uncertainty in the estimate -- at this time, we argue it is still large.

description: Ultrahigh-energy cosmic rays (UHECRs), if accelerated in the gamma-ray burst (GRB) blastwave, are expected to produce PeV-EeV neutrinos by interacting with long-lived GRB afterglow photons. Detailed spectral and temporal properties of the flux of these neutrinos depend on the GRB blastwave evolution scenario, but can last for days to years time scale in contrast to the seconds to minutes time scale for "burst" neutrino flux contemporaneous with the prompt gamma-ray emission and which has been constrained by IceCube in the $\sim$ 50 TeV-2 PeV range. We compute expected neutrino events in IceCube in the PeV-EeV range from the blastwave of long-duration GRBs, both for the diffuse flux and for individual GRBs in the nearby universe. We show that IceCube will be able to detect the diffuse GRB blastwave neutrino flux after 5 years of operation, and will be able to distinguish it from the cosmogenic neutrino flux arising from GZK process in case the UHECRs are heavy nuclei. We also show that EeV neutrinos from the blastwave of an individual GRB can be detected with long-term monitoring by a future high-energy extension of IceCube for redshift up to $z\sim 0.5$.

Equation of state of the trans-Planckian dark energy and the coincidence problem

description: Observational evidence suggests that our Universe is presently dominated by a dark energy component and is undergoing accelerated expansion. We recently introduced a model, motivated by string theory for short-distance physics, for explaining dark energy without appealing to any fine tuning. The idea of trans-Planckian dark energy (TDE) was based on the freeze-out mechanism of the ultralow frequency modes, [Formula Presented] of very short distances, by the expansion of the background universe, [Formula Presented] In this paper we address the issue of the stress-energy tensor for nonlinear short-distance physics and explain the need to modify Einstein equations in this regime. From the modified Einstein equations we then derive the equation of state for the TDE model, which has the distinctive feature of being continually time dependent. The explanation of the coincidence puzzle relies entirely on the intrinsic time evolution of the TDE equation of state.
Raman Spectroscopy of Electrochemically-Gated Graphene Transistors: Geometrical Capacitance, Electron-Phonon, Electron-Electron, and Electron-Defect Scattering

description: We report a comprehensive micro-Raman scattering study of electrochemically-gated graphene field-effect transistors. The geometrical capacitance of the electrochemical top-gates is accurately determined from dual-gated Raman measurements, allowing a quantitative analysis of the frequency, linewidth and integrated intensity of the main Raman features of graphene. The anomalous behavior observed for the G-mode phonon is in very good agreement with theoretical predictions and provides a measurement of the electron-phonon coupling constant for zone-center ($Γ$ point) optical phonons. In addition, the decrease of the integrated intensity of the 2D-mode feature with increasing doping, makes it possible to determine the electron-phonon coupling constant for near zone-edge (K and K' points) optical phonons. We find that the electron-phonon coupling strength at $Γ$ is five times weaker than at K (K'), in very good agreement with a direct measurement of the ratio of the integrated intensities of the resonant intra- (2D') and inter-valley (2D) Raman features. We also show that electrochemical reactions, occurring at large gate biases, can be harnessed to efficiently create defects in graphene, with concentrations up to approximately $1.4\times 10^{12}~\rm cm^{-2}$. At such defect concentrations, we estimate that the electron-defect scattering rate remains much smaller than the electron-phonon scattering rate. The evolution of the G- and 2D-mode features upon doping remain unaffected by the presence of defects and the doping dependence of the D mode closely follows that of its two-phonon (2D mode) overtone. Finally, the linewidth and frequency of the G-mode phonon as well as the frequencies of the G- and 2D-mode phonons in doped graphene follow sample-independent correlations that can be utilized for accurate estimations of the charge carrier density.

description: We investigate the effects of quantum entanglement between our horizon patch and others due to the tracing out of long wavelength modes in the wave function of the Universe as defined on a particular model of the landscape. In this, the first of two papers devoted to this topic, we find that the SUSY breaking scale is bounded both above and below: 10-10MP≤MSUSY≤10-8MP for grand unified theory (GUT) scale inflation. Bounds on the SUSY breaking parameter depend on the scale of inflation. If inflation occurred at GUT energies, the lower bound on b is at least 5 orders of magnitude larger than the expected value of this parameter, soon to be tested by LHC.

description: Chiral fermions can be embedded into Souriau's massless spinning particle model by "enslaving" the spin, viewed as a gauge constraint. The latter is not invariant under Lorentz boosts; spin enslavement can be restored, however, by a subsequent Wigner-Souriau (WS) translation, analogous to a compensating gauge transformation. The combined transformation is precisely the recently uncovered twisted boost, which we now extend to finite transformations. WS-translations are identified with the stability group of a motion acting on the right on the Poincare group, whereas the natural Poincare action corresponds to action on the left. The relation to non-commutative mechanics is explained.

description: The Wilkinson Microwave Anisotropy Probe microwave background data may be giving us clues about new physics at the transition from a "stringy" epoch of the Universe to the standard Friedmann-Robertson-Walker description. Deviations on large angular scales of the data, as compared to theoretical expectations, as well as running of the spectral index of density perturbations, can be explained by new physics whose scale is set by the height of an inflationary potential. As examples of possible signatures for this new physics, we study the cosmic microwave background spectrum for two string inspired models: (1) modifications to the Friedmann equations and (2) velocity dependent potentials. The suppression of low "l" modes in the microwave background data arises due to the new physics. In addition, the spectral index is red (n<1) on small scales and blue (n>1) on large scales, in agreement with data.

ABJM Theory with mass and FI deformations and Quantum Phase Transitions

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The phase structure of ABJM theory with mass $m$ deformation and non-vanishing Fayet-Iliopoulos (FI) parameter, $ζ$, is studied through the use of localisation on ${\mathbb S}^3$. The partition function of the theory then reduces to a matrix integral, which, in the large $N$ limit and at large sphere radius, is exactly computed by a saddle-point approximation. When the couplings are analytically continued to real values, the phase diagram of the model becomes immensely rich, with an infinite series of third-order phase transitions at vanishing FI-parameter. As the FI term is introduced, new effects appear. For any given $0 < ζ< m/2$, the number of phases is finite and for $ζ\geq m/2$ the theory does not have any phase transitions at all. Finally, we argue that ABJM theory with physical couplings does not undergo phase transitions and investigate the case of $U(2)\times U(2)$ gauge group in detail by an explicit calculation of the partition function.

Investigation of the selection of original universe proposal

description: We investigate the Selection of Original Universe Proposal (SOUP) of Tye et al and show that as it stands, this proposal is flawed. The corrections to the Euclidean gravity action that were to select a Universe with a sufficiently large value of the cosmological constant Λ to allow for an inflationary phase only serve to renormalize the cosmological constant so that Λ→Λeff. SOUP then predicts a wave function that is highly peaked around Λeff→0, thereby reintroducing the issue of how to select initial conditions allowing for inflation in the early Universe.

Converting the long-distance matrix elements (LDMEs) extracted by various groups from $J/ψ$ yield and polarization data to the $η_c$ case using heavy-quark spin symmetry, we find that the resulting NLO NRQCD predictions greatly overshoot the LHCb data, while the color-singlet model provides an excellent description.

Supernova type Ia data and the cosmic microwave background of modified curvature at short and large distances
Creators: name: Mersini, L.
name: Bastero-Gil, M.
Publisher: name: American Physical Society
Year: 2002

description: The SNIa data, although inconclusive, when combined with other observations makes a strong case that our universe is presently dominated by dark energy. We investigate the possibility that large distance modifications of the curvature of the universe would perhaps offer an alternative explanation of the observation. Our calculations indicate that a universe made up of no dark energy but instead, with a modified curvature at large scales, is not scale invariant; therefore quite likely it is ruled out by the CMB observations. The sensitivity of the CMB spectrum is checked for the whole range of mode modifications of large or short distance physics. The spectrum is robust against modifications of short-distance physics and the UV cutoff when the initial state is the adiabatic vacuum, and the inflationary background space is de Sitter space.

description: Control strategies for dissipative preparation of target quantum states, both pure and mixed, and subspaces are obtained by switching between a set of available semigroup generators. We show that the class of problems of interest can be recast, from a control--theoretic perspective, into a switched-stabilization problem for linear dynamics. This is attained by a suitable affine transformation of the coherence-vector representation. In particular, we propose and compare stabilizing time-based and state-based switching rules for entangled state preparation, showing that the latter not only ensure faster convergence with respect to non-switching methods, but can designed so that they retain robustness with respect to initialization, as long as the target is a pure state or a subspace.

Can we live in a self-tuning universe?
Creators: name: Mersini, L.
name: Carroll, S.M.
Publisher: name: American Physical Society
Year: 2001

description: The self-tuning brane scenario is an attempt to solve the cosmological constant problem in the context of extra dimensions. Rather than making the vacuum energy small, this approach proceeds by removing the gravitational effect of vacuum energy on the expansion of the universe. Such behavior is only possible through changing the Friedmann equation of conventional cosmology, and we discuss difficulties in obtaining cosmological evolution compatible with observation in this context. Specific models considered include a bulk scalar field coupling to the brane via a conformal transformation of the brane metric, and via a rescaling of the brane volume element.

description: By combining data from seven cosmic microwave background experiments (including the latest WMAP results) with the Hubble parameter measurement from the Hubble space telescope and luminosity measurements of type la supernovae, we demonstrate the bounds on the dark energy equation of state wQ to be - 1.45<wQ< -0.74 at the 95% confidence level. Although our limit on wQ is improved with respect to previous analyses, cosmological data do not rule out the possibility that the equation of state parameter wQ of the dark energy Q is less than -1. We present a tracking model that ensures wQ≤- 1 at recent times and discuss the observational consequences.

description: The study evaluated the effect of local government revenue generation on the medical services and supply systems in Enugu state: A survey of selected local government areas. The specific objectives were to: Ascertain the effect of local government revenue generation on the medical supply systems in Enugu State and to determine the effect of local government revenue generation on health care services in Enugu State. The actual population was Nine thousand, three hundred and thirteen staff (906). The population of the study was drawn from the entire members of the local government staff and, executives of the town union leaders and selected individuals. The sample size of 537 was drawn using Freund and William’s formula at 3 percent error margin. A survey design was adopted for the study. Instrument used for data collection was the questionnaire and interviews. A total of five hundred and thirty-seven (537) copies of questionnaire were distributed while four hundred and seventy-three (473) copies of questionnaire were returned. Z – test was used to test the hypothesis one and determine the nature, and strength of the research variables, while Chi-square was used to test hypothesis two. The findings indicated that Local government revenue generation had positive significant effect on the medical supply systems in Enugu State Z (95, n = 473) = .283 < .352, p < 0.03. and that the Local government revenue generation did not significantly impact health care service delivery in Enugu State, D.F = 16; 2cal = 85.598, p = 0.060. The study concluded that Local government revenue generation had positive influence on medical supply systems and had negative impact on health care service delivery in Enugu State.  The study recommended that among others that the local government should increase the number of health institutions to attract healthier workforce to the local government and enhance more provision of services

description: Oscillations and noise are ubiquitous in physical and biological systems. When oscillations arise from a deterministic limit cycle, entrainment and synchronization may be analyzed in terms of the asymptotic phase function. In the presence of noise, the asymptotic phase is no longer well defined. We introduce a new definition of asymptotic phase in terms of the slowest decaying modes of the Kolmogorov backward operator. Our stochastic asymptotic phase is well defined for noisy oscillators, even when the oscillations are noise dependent. It reduces to the classical asymptotic phase in the limit of vanishing noise. The phase can be obtained either by solving an eigenvalue problem, or by empirical observation of an oscillating density's approach to its steady state.

description: We use the thin-shell Darmois-Israel formalism to model and assess the stability of the interfaces separating phases, e.g. the core and the crust, within compact stars. We exemplify the relevance and non-triviality of this treatment in the simplest case of an incompressible star, in constant pressure phase transitions, and in the case of strange quark stars with crust.

description: Abstract: Trauma-informed care is a growing practice approach in child and family social work. Current policy directions in out-of-home care (OOHC) in Victoria, Australia show an interest in further implementation of trauma-informed care, particularly through training for foster and kinship carers. Drawing upon findings from grounded theory research with sixteen foster and kinship carers, this article considers the application of trauma-informed practices in home-based care in the Central Highlands region of Victoria, Australia. The research reveals that whilst carers utilise principles of trauma-informed care to support children and young people, they do not always experience trauma-informed support from the wider OOHC system. This discrepancy suggests that the implementation of trauma-informed care has the potential to increase pressure on home-based carers if it is only encouraged at the interpersonal level between carers and children, without incorporating associated systems-level change. These findings propose that whilst micro-level support and training for carers are necessary and useful, it is crucial for OOHC systems to move beyond such initiatives to plan and enact macro-level reforms.

description: As yet, there is no underlying fundamental theory for the trans-Planckian regime. There is a need to address the issue of how the observables in our present Universe are affected by processes that may have occurred at super-Planckian energies (referred to as the trans-Planckian regime). Specifically, we focus on the impact the trans-Planckian regime has on two observables: namely, dark energy and the cosmic microwave background radiation (CMBR) spectrum. We model the trans-Planckian regime by introducing a 1-parameter family of smooth non-linear dispersion relations which modify the frequencies at very short distances. A particular feature of the family of dispersion functions chosen is the production of ultralow frequencies at very high momenta k (for k>MP). We name the range of the ultralow energy modes (of very short distances) that have frequencies equal to or less than the current Hubble rate H0 as the tail modes. These modes are still frozen today due to the expansion of the Universe. We calculate their energy today and show that the tail provides a strong candidate for the dark energy of the Universe. During inflation, their energy is about 122 to 123 orders of magnitude smaller than the total energy, for any random value of the free parameter in the family of dispersion relations. For this family of dispersions, we present the exact solutions and show that the CMBR spectrum is that of a (nearly) blackbody, and that the adiabatic vacuum is the only choice for the initial conditions.

description: Background: Owing to the rarity and heterogenicity , Behcet’s disease (BD) remains a diagnostic and management challenge to the internists and rheumatologists alike. Diagnosis is difficult and often of exclusion. Exact prevalence in Indian subcontinent is not known. Objectives: To study varied clinical manifestations and treatment outcomes of BD presenting to a tertiary care hospital in north India. Method: Short case series of 4 cases who presented to rheumatology clinic of tertiary care hospital in north India from January 2020 to January 2021. Clinical details, laboratory and radiological findings , treatment details and outcomes were recorded. Results: First patient was a prototype case and responded well to first line therapies. In case 2 episodes of syncope pointed towards possible vascular insufficiency which on subsequent evaluation with carotid artery doppler and CT aortography revealed large vessel vasculitis(LVV). Early diagnosis in absence of frank signs of LVV and aggressive treatment altered disease course towards better outcome. In case 3, large vessel vasculitis with stenotic lesions involving pulmonary arteries and aorta was quite atypical as Bechet’s disease is known to have pulmonary artery aneurysm. Presence of other clinical features favored the diagnosis of Bechet’s disease over Takayasu. In case 4, initial presentation with only retinal vasculitis, a drug free remission period of fourteen years followed by orogenital ulcers was quite atypical. Although the patient had accrued damage in the form of bilateral optic atrophy with macular scarring infliximab was given to preserve the residual vision. Conclusion: Diverse clinical manifestations and atypical presentations make the diagnosis of this not so common variable vessel vasculitis all the more challenging. Delay in diagnosis and management leads to damage accrual with increased morbidity and mortality risk. It is prudent to have high index of suspicion given early immunosuppressive therapy can favorably alter the disease course.

description: We discuss a general duality principle, between noncommutative analogues of the standard cube $\mathbb Z_2^N$, and nonocommutative analogues of the standard sphere $S^{N-1}_\mathbb R$. This duality is by construction of algebraic geometric nature, and conjecturally connects the corresponding quantum isometry groups, taken in an affine sense.

description: The recent detection of hypervelocity stars (HVSs) as late-type B-stars and HVS candidate G/K-dwarfs raises the important question of their origin. In this Letter, we investigate the maximum possible velocities of such HVSs if they are produced from binaries which are disrupted via an asymmetric supernova explosion. We find that HVSs up to ~770 and ~1280 km/s are possible in the Galactic rest frame from this scenario for these two subclasses of HVSs, respectively. We conclude that whereas a binary origin cannot easily explain all of the observed velocities of B-type HVSs (in agreement with their proposed central massive black hole origin) it can indeed account for the far majority (if not all) of the recently detected G/K-dwarf HVS candidates.

Radion potential and brane dynamics
Creators: name: Mersini, L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2001

description: We examine the cosmology of Randall-Sundrum model in a dynamic setting where scalar fields are present in the bulk as well as the branes. This generates a mechanism similar to that of Goldberger-Wise for radion stabilization and the recovery of late-time cosmology features on the branes. Due to the induced radion dynamics, the inflating branes roll towards the minimum of the radion potential, thereby exiting inflation and reheating the universe. In the slow roll part of the potential, the TeV branes have maximum inflation rate and energy as their coupling to the radion and bulk modes have minimum suppression. Hence, when rolling down the steep end of the potential towards the stable point, the radion field (which appears as the inflaton of the effective 4-D theory in the branes) decays very fast and reheats the universe. This process results in a decrease of the brane's canonical vacuum energy, Λ4. However, at the minimum of the potential Λ4 is small but not necessarily zero and the fine-tuning issue remains. Density perturbation constraints introduce an upper bound on Λ4. Due to the large radion mass and strong suppression to the bulk modes, moduli problems and bulk reheating do not occur. The reheat temperature and a sufficient number of e-folding constraints for the brane-universe are also satisfied. The model therefore recovers the radiation dominated FRW universe.
Field configurations and their instability induced by higher dimensions of space-time: An example
Creators: name: Mersini, L.
Publisher: name: World Scientific Publishing Co. Pte Ltd

description: We use the model of L. Randall et al.3 to investigate the stability of allowed quantum field configurations. Firstly, we find that due to the topology of this five-dimensional model, there are two possible configurations of the scalar field, untwisted and twisted. They give rise to two types of instability. Secondly, when allowed to interact in the brane, the untwisted field is shown to be unstable even if it is at the true vacuum ground state as a result of one-loop corrections that arise from coupling with the twisted field. On the other hand, the twisted field can make the two three-branes (that are otherwise identical in their properties and geometry) distinguishable therefore causing an energy difference between them. That is due to the antiperiodicity of the twisted fields, when rotating with π to go from one three-brane to the other. This energy difference between the branes renders the fifth dimension unstable. This toy model is simple enough to use to illustrate a point that can be important for the general case of any high dimension model, namely: higher dimensions, besides many other effects can also induce more than one field configuration and that can have consequences (e.g. instabilities) even after reducing the problem to four dimensions.

description: Driven optical lattices permit the engineering of effective dynamics with well-controllable tunneling properties. We describe the realization of a tunable a Chern insulator by driving particles on a shaken hexagonal lattice with optimally designed polychromatic driving forces. Its implementation does not require shallow lattices, which favors the study of strongly-correlated phases with non-trivial topology.
