Mathematics, 2022 The nonrelativistic treatment of the Varshni–Shukla potential (V–SP) in the presence of magnetic and Aharanov–Bohm fields is carried out using the asymptotic iteration method (AIM). The energy equation and wave function are derived analytically.

Weyl Anomaly in NonRelativistic CFTs [PDF]
Phys.Lett.B685:341-346,2010, 2009 We study Weyl symmetry for non-relativistic conformal filed theories on curved spatial spaces, and calculate it's quantum anomaly. We show that there is no geometric anomaly, and the non-relativistic Weyl anomaly can appear only due to interaction. Also we study the anomaly by using the light-cone approach.

New Physics beyond the 750 GeV diphotons events
EPJ Web of Conferences, 2016 the 750 GeV diphoton anomaly observed by ATLAS and CMS collaborations in 2015, and the models suggested by theorists to explain it. The talk has been presented in the special session devoted to this anomaly and possible (new) physics behind it. Since all

Hybrid data-driven physics model-based framework for enhanced cyber-physical smart grid security
IET Smart Grid, 2019 This study presents a hybrid data-driven physics model-based framework for real-time monitoring in smart grids. As the power grid transitions to the use of smart grid technology, it's real-time monitoring becomes more vulnerable to cyber-attacks like ...

A connection between flavour anomaly, neutrino mass, and axion
Journal of High Energy Physics, 2020 We propose a minimal model in which the flavour anomaly in the b → sμ + μ − transition is connected to the breaking of Peccei-Quinn (PQ) symmetry. The flavour anomaly is explained from new physics contribution by introducing one generation of heavy quark

Beyond Symmetries : Anomalies in Transverse Ward--Takahashi Identities [PDF]
Phys. Rev. D 102, 056008 (2020), 2020 Anomalies in transverse Ward--Takahashi identities are studied, allowing discussion of the feasibility of anomalies arising in general non-symmetry Ward--Takahashi identities. We adopt the popular Fujikawa's method and rigorous dimensional renormalization to verify the existence of transverse anomalies to one-loop order and any loop order, respectively.

Conformal anomaly and helicity effects in kinetic theory via scale-dependent coupling [PDF]
Phys. Rev. D 103, 036019 (2021), 2020 We modify a kinetic theory of massless fermions to incorporate the effects of the conformal anomaly. Working in a collisionless regime, we emulate the conformal anomaly via a momentum-dependent electric coupling. In this prescription, the conformal anomaly leads to a hedgehog-like structure in the momentum space similar to the Berry phase associated ...

The Chiral Anomaly in SCET [PDF]
Phys.Rev.D79:036003,2009, 2008 Anomalies are an infrared effect, but are often realized in effective theories in a non-trivial way. We study the chiral anomaly in Soft Collinear Effective Theory (SCET), where the anomaly equation has terms contributing at different orders in the power expansion.

A Modern Point of View on Anomalies [PDF]
, 2019 We review the concept of anomaly field theory, namely the fact that the anomalies of a $d$-dimensional field theory can be encoded in a $d+1$-dimensional field theory functor. We give numerous examples of anomaly field theories, explain how classical facts about anomalies are recovered from the anomaly field theory, and review recent work on global ...

Classifying gauge anomalies through SPT orders and classifying gravitational anomalies through topological orders [PDF]
Phys. Rev. D 88, 045013 (2013), 2013 In this paper, we systematically study gauge anomalies in bosonic and fermionic weak-coupling gauge theories with gauge group G (which can be continuous or discrete). We show a very close relation between gauge anomalies and symmetry-protected trivial (SPT) orders [also known as symmetry-protected topological (SPT) orders] in one-higher dimensions ...
