    Superconformal monodromy defects in ABJM and mABJM theory

    , The Journal of High Energy Physics, Vol: 2024, ISSN: 1029-8479

    We study D = 11 supergravity solutions which are dual to one-dimensional superconformal defects in d = 3 SCFTs. We consider defects in ABJM theory with monodromy for U(1)4 ⊂ SO(8) global symmetry, as well as in 𝒩 = 2 mABJM SCFT, which arises from the RG flow of a mass deformation of ABJM theory, with monodromy for U(1)3 ⊂ SU(3) × U(1) global symmetry. We show that the defects of the two SCFTs are connected by a line of bulk marginal mass deformations and argue that they are also related by bulk RG flow. In all cases we allow for the possibility of conical singularities at the location of the defect. Various physical observables of the defects are computed including the defects conformal weight and the partition function, as well as associated supersymmetric Renyi entropies.

    In-flight performance of Spider’s 280-GHz receivers

    , Journal of Astronomical Telescopes, Instruments, and Systems, Vol: 10, ISSN: 2329-4221

    Spider is a balloon-borne instrument designed to map the cosmic microwave background at degree-angular scales in the presence of Galactic foregrounds. Spider has mapped a large sky area in the Southern Hemisphere using more than 2000 transition-edge sensors (TESs) during two NASA Long Duration Balloon flights above the Antarctic continent. During its first flight in January 2015, Spider was observed in the 95- and 150-GHz frequency bands, setting constraints on the B-mode signature of primordial gravitational waves. Its second flight in the 2022–2023 season added new receivers at 280 GHz, each using an array of TESs coupled to the sky through feedhorns formed from stacks of silicon wafers. These receivers are optimized to produce deep maps of polarized Galactic dust emission over a large sky area, providing a unique data set with lasting value to the field. We describe the instrument’s performance during Spider’s second flight, focusing on the performance of the 280-GHz receivers. We include details on the flight, in-band optical loading at float, and an early analysis of detector noise.

    Localization of the free energy in supergravity

    , Physical Review Letters, Vol: 133, ISSN: 0031-9007

    We derive a general formula for the gravitational free energy of Euclidean supersymmetric solutions toD ¼ 4, N ¼ 2 gauged supergravity coupled to vector multiplet matter. This allows one to compute the freeenergy without solving any supergravity equations, just assuming the solutions exist. As well as recoveringsome known results in the literature with ease, we also present new supergravity results that match withholographically dual field theory computations.

    The Behavioural House Indicator: a faster and real time small-area indicative deprivation measure for England

    , Environment and Planning B: Urban Analytics and City Science, ISSN: 2399-8083

    Researchers have been long preoccupied with the measuring and monitoring of economic and social deprivation at small scales, neighbourhood, level in order to provide official government agencies and policy makers with more precise data insights. Whist valuable methodologies have been developed, the exercise of data collection associated with these methods tends to be expensive, time consuming, published infrequently with significant time delays, and subject to recurring changes to methodology. Here, we propose a novel method based on a straightforward methodology and data sources to generate a faster and real time indicator for deprivation at different scaling, small to larger areas. The results of our work show that our method provides a consistent view of deprivation across the regions of England and Wales, which are in line with the other indexes, but also highlight specific flash points of deep rural and highly dense urban deprivation areas that are not well captured by existing indexes. Our method is intended to aid researchers and policy makers by complementing existing but infrequent indexes.

    Superconformal monodromy defects in N=4 SYM andLS theory

    , The Journal of High Energy Physics, Vol: 2024, ISSN: 1029-8479

    We study type IIB supergravity solutions that are dual to two-dimensionalsuperconformal defects in d = 4 SCFTs which preserve N = (0, 2) supersymmetry. Weconsider solutions dual to defects in N = 4 SYM theory that have non-trivial monodromy forU(1)3 ⊂ SO(6) global symmetry and we also allow for the possibility of conical singularities.In addition, we consider the addition of fermionic and bosonic mass terms that have nontrivial dependence on the spatial directions transverse to the defect, while preserving thesuperconformal symmetry of the defect. We compute various physical quantities including thecentral charges of the defect expressed as a function of the monodromy, the on-shell action aswell as associated supersymmetric Rényi entropies. Analogous computations are carried outfor superconformal defects in the N = 1, d = 4 Leigh-Strassler SCFT. We also show thatthe defects of the two SCFTs are connected by a line of bulk marginal mass deformationsand argue that they are also related by bulk RG fow.

    Vortices, topology and time

    , Physics Letters B: Nuclear Physics and Particle Physics, Vol: 855, ISSN: 0370-2693

    We relate physical time with the topology of magnetic field vortices. We base ourselves on a formulation of unimodular gravity where the cosmological constant Λ appears as the canonical dual to a variable which on-shell becomes four-volume time. If the theory is restricted to a topological axionic form (viz. a parity-odd product of an electric and a magnetic field), such a time variable becomes the spatial integral of the Chern-Simons density. The latter equates to helicity, so that unimodular time is transmuted into the linking number of the vortices of the topological magnetic field, times their flux. With the added postulate that this flux is a universal constant, the flow of time can thus be interpreted as the progressive weaving of further links between magnetic field vortices, each link providing a quantum of time with value related to the fixed flux. Non-abelian extensions, and targetting parameters other than Λ are briefly examined, exposing different types of vortices and a possible role for inter-linking leading to new phenomenology.

    Machine Learning Clifford Invariants of ADE Coxeter Elements

    , Advances in Applied Clifford Algebras, Vol: 34, ISSN: 0188-7009

    <jats:title>Abstract</jats:title><jats:p>There has been recent interest in novel Clifford geometric invariants of linear transformations. This motivates the investigation of such invariants for a certain type of geometric transformation of interest in the context of root systems, reflection groups, Lie groups and Lie algebras: the Coxeter transformations.

    Dark matter and spacetime symmetry restoration

    , Physical Review D: Particles, Fields, Gravitation and Cosmology, Vol: 109, ISSN: 1550-2368

    We examine local physics in the presence of global variables: variables associated with the whole of the spacelike surfaces of a foliation. These could be the (pseudo)constants of nature and their conjugate times, but our statements are more general. Interactions between the local and the global (for example, dependence of the local action on global times dual to constants) degrades full space-time diffeomorphism invariance down to spatial diffeomorphism invariance, and so an extra degree of freedom appears. When these presumably primordial global interactions switch off, the local action recovers full invariance and so the usual two gravitons, but a legacy matter component is left over, bearing the extra degree of freedom. Under the assumption that the preferred foliation is geodesic, this component behaves like dark matter, except that 3 of its 4 local degrees of freedom are frozen, forcing its rest frame to coincide with the preferred foliation. The nonfrozen degree of freedom (the number density of the effective fluid) is the survivor of the extra “graviton” present in the initial theory and keeps memory of all the past global interactions that took place in a given location in the preferred foliation. Such “painted-on” dark matter is best distinguished from the conventional one in situations where the preferred frame would be preposterous if all 4 degrees of freedom of dark matter were available. We provide one example: an outflowing halo of legacy matter with exact escape speed at each point and a very specific profile, surrounding a condensed structure made of normal matter.
