Radiative Decay Widths of Ground and Excited States of Vector Charmonium and Bottomonium by Hluf Negash, Shashank Bhatnagar

“…We study the radiative decay widths of vector quarkonia for the process of J/ψ(nS)→ηc(nS)γ and Υ(nS)→ηb(nS)γ (for principal quantum numbers n=1,2,3) in the framework of Bethe-Salpeter equation under the covariant instantaneous ansatz using a 4×4 form of BSE. …”

Nonlocal order parameter of pair superfluids by Nitya Cuzzuol, Luca Barbiero, Arianna Montorsi

“…Order parameters represent a fundamental resource to characterize quantum matter. We show that pair superfluids can be rigorously defined in terms of a nonlocal order parameter, named odd parity, which derivation is experimentally accessible by local density measurements. …”

Some New Transformation Properties of the Nielsen Generalized Polylogarithm by Nina Shang, Qinghua Feng, Huizeng Qin

“…Many of the properties of Nielsen generalized polylogarithm Sn,p(z), for example, the special value and the transformation formulas, play important roles in the computation of higher order radiative corrections in quantum electrodynamics. In this paper, some transformation formulas of z→p(z),p(z)=1-z,1/z,1/(1-z),z/(z-1), and (1-z)/z are obtained. …”

Quasinormal modes of regular black holes with sub-Planckian curvature and Minkowskian core by Chen Tang, Yi Ling, Qing-Quan Jiang, Guo-Ping Li

“…The outburst of overtones is manifestly observed in the QNMs of these regular black holes, which can be attributed to the deviation of the Schwarzschild black hole by quantum effects of gravity. Furthermore, the QNMs under the perturbation of electromagnetic field exhibit smaller real and imaginary parts than those under scalar field perturbation. …”

Spin cobordism and the gauge group of type I/heterotic string theory by Christian Kneißl

“…Abstract Cobordism offers a unique perspective into the non-perturbative sector of string theory by demanding the absence of higher form global symmetries for quantum gravitational consistency. In this work we compute the spin cobordism groups of the classifying space of Spin(32)/ℤ2 relevant to describing type I/heterotic string theory and explore their (shared) non-perturbative sector. …”

The edge of random tensor eigenvalues with deviation by Nicolas Delporte, Naoki Sasakura

“…Abstract The largest eigenvalue of random tensors is an important feature of systems involving disorder, equivalent to the ground state energy of glassy systems or to the injective norm of quantum states. For symmetric Gaussian random tensors of order 3 and of size N, in the presence of a Gaussian noise, continuing the work [1], we compute the genuine and signed eigenvalue distributions, using field theoretic methods at large N combined with earlier rigorous results of [2]. …”
