Monopole operators from the 4−ϵ4-\epsilon expansion

Three-dimensional quantum electrodynamics with $N$ charged fermions contains monopole operators that have been studied perturbatively at large $N$. Here, we initiate the study of these monopole operators in the $4-\epsilon$ expansion by generalizing them to codimension-3 defect operators in $d = 4-\epsilon$ spacetime dimensions. Assuming the infrared dynamics is described by an interacting CFT, we define the "conformal weight" of these operators in terms of the free energy density on $S^2 \times \mathbb{H}^{2-\epsilon}$ in the presence of magnetic flux through the $S^2$, and calculate this quantity to next-to-leading order in $\epsilon$. Extrapolating the conformal weight to $\epsilon = 1$ gives an estimate of the scaling dimension of the monopole operators in $d=3$ that does not rely on the $1/N$ expansion. We also perform the computation of the conformal weight in the large $N$ expansion for any $d$ and find agreement between the large $N$ and the small $\epsilon$ expansions in their overlapping regime of validity.Comment: 45 pages, 3 figures, version accepted by journa

Monopole Operators in U(1)U(1) Chern-Simons-Matter Theories

We study monopole operators at the infrared fixed points of $U(1)$ Chern-Simons-matter theories (QED$_3$, scalar QED$_3$, ${\cal N} =1$ SQED$_3$, and ${\cal N} = 2$ SQED$_3$) with $N$ matter flavors and Chern-Simons level $k$. We work in the limit where both $N$ and $k$ are taken to be large with $\kappa = k/N$ fixed. In this limit, we extract information about the low-lying spectrum of monopole operators from evaluating the $S^2 \times S^1$ partition function in the sector where the $S^2$ is threaded by magnetic flux $4 \pi q$. At leading order in $N$, we find a large number of monopole operators with equal scaling dimensions and a wide range of spins and flavor symmetry irreducible representations. In two simple cases, we deduce how the degeneracy in the scaling dimensions is broken by the $1/N$ corrections. For QED$_3$ at $\kappa=0$, we provide conformal bootstrap evidence that this near-degeneracy is in fact maintained to small values of $N$. For ${\cal N} = 2$ SQED$_3$, we find that the lowest dimension monopole operator is generically non-BPS.Comment: 52 pages plus appendices, 9 figures, v2: minor correction

The Market Valuation Of Earnings In Germany, The United Kingdom And The United States

This paper examines a short-term market reaction to unexpected earnings in the United Kingdom, Germany, and the United States. The results indicate that all three markets react quickly to earnings releases.  Further, when changes in analysts’ forecasts are used as an indication of updated earnings expectations, all three markets respond as well.  Thus, it appears that investors in both countries react to the release of unexpected earnings in a similar manner.  We also examine the incremental explanatory power of analysts’ forecast errors over the change in earnings per share.  As all three countries have well developed stock markets, investors are likely to formulate earnings expectations based on a wide range of financial and non-financial information, including analysts’ forecasts.  Regression results indicate that in Germany, the UK and the US, both analysts' forecasts and earnings announcements are jointly associated with market returns suggesting that the analysts provide information incremental to that provided in earnings releases

Altimetric system: Earth observing system. Volume 2h: Panel report

A rationale and recommendations for planning, implementing, and operating an altimetric system aboard the Earth observing system (Eos) spacecraft is provided. In keeping with the recommendations of the Eos Science and Mission Requirements Working Group, a complete altimetric system is defined that is capable of perpetuating the data set to be derived from TOPEX/Poseidon, enabling key scientific questions to be addressed. Since the scientific utility and technical maturity of spaceborne radar altimeters is well documented, the discussion is limited to highlighting those Eos-specific considerations that materially impact upon radar altimetric measurements

Exploring the Reality of Hog Raisers in Cebu Amidst the African Swine Fever (ASF) Outbreak

Hog farming is a significant industry in the Philippines, providing 60% of the country's animal meat consumption. However, the African Swine Fever (ASF) outbreak has caused its collapse. In effect, the hog raisers stopped their operation and sought alternatives to earn money for the family's needs. As a result, a phenomenological study investigated the hog raisers' lived experiences and how they cope with the existing phenomenon. Six key informants were selected based on inclusion criteria and purposive sampling for one-on-one interviews conducted by researchers. Using Creswell's approach, (1) fear of the virus, (2) frustration from the border controls and lockdowns, (3) broken promises of financial assistance from the Department of Agriculture, and (4) incurred substantial financial loss were themes concerning the lived experiences of the key informants. Also, the key informants shared how they coped with the outbreak, including (1) shifting to a farming business, (2) working in a construction site, and (3) making hollow blocks. An effective approach to combat the ASF outbreak in Cebu necessitates a comprehensive strategy that draws on insights from key informants. It is imperative to establish systems of support that consider the financial, emotional, and psychological needs of those affected. Collaborative efforts with local communities, researchers, and government organizations are also crucial to devising sustainable plans for managing and preventing ASF in the long run. This study sheds light on the obstacles encountered by the hog industry in Cebu and underscores the significance of implementing coordinated measures to mitigate the effects of ASF
