A guide to the QCD light-cone sum rules for b-quark decays
We overview the current status and future perspectives of the QCD-based method of light-cone sum rules. The two main versions of these sum rules,...

Strange-quark mass effects in the Bs meson’s light-cone distribution amplitude
We investigate the differences between the light-cone distribution amplitudes (LCDAs) of B s mesons and B q mesons (with q = u , d ) induced by a...

Hybrid Dirac semimetal-based photodetector with efficient low-energy photon harvesting
Despite the considerable effort, fast and highly sensitive photodetection is not widely available at the low-photon-energy range (~meV) of the...

General light-cone gauge approach to conformal fields and applications to scalar and vector fields
Totally symmetric arbitrary spin conformal fields propagating in the flat space of even dimension greater than or equal to four are studied. For such...

On the calculation of covariant expressions for Dirac bilinears
In this article, various approaches to calculate covariant expressions for the bilinears of Dirac spinors are presented. For this purpose, algebraic...

Gravitational transition form factors of N → ∆ via QCD light-cone sum rules
We present the first direct calculation on the gravitational form factors (GFFs) of the N → ∆ transition using an analytic method, the QCD light-cone...

Connecting Euclidean to light-cone correlations: from flavor nonsinglet in forward kinematics to flavor singlet in non-forward kinematics
We present a unified framework for the perturbative factorization connecting Euclidean correlations to light-cone correlations. Starting from...

Tunable Berry curvature and transport crossover in topological Dirac semimetal KZnBi
Topological Dirac semimetals have emerged as a platform to engineer Berry curvature with time-reversal symmetry breaking, which allows to access...

Lessons from discrete light-cone quantization for physics at null infinity: bosons in two dimensions
Motivated by issues in the context of asymptotically flat spacetimes at null infinity, we discuss in the simplest example of a free massless scalar...

Manipulation of Dirac band curvature and momentum-dependent g factor in a kagome magnet
The Zeeman effect describes the energy change of an atomic quantum state in a magnetic field. The magnitude and direction of this change depend on...

Gravitational SL(2, ℝ) algebra on the light cone
In a region with a boundary, the gravitational phase space consists of radiative modes in the interior and edge modes at the boundary. Such edge...

Vortical effects in Dirac fluids with vector, chiral and helical charges
Helicity of free massless Dirac fermions is a conserved, Lorentz-invariant quantity at the level of the classical equations of motion. For a generic...

Late time decay of scalar and Dirac fields around an asymptotically de Sitter black hole in the Euler–Heisenberg electrodynamics
We compute the quasinormal modes of massive scalar and Dirac fields within the framework of asymptotically de Sitter black holes in Euler–Heisenberg...

Quantum spin mixing in Dirac materials
The spin of the electron is nowadays replacing the charge as basic carrier of information not only in spintronics applications, but also in the...

‘Real’ Gerbes and Dirac Cones of Topological Insulators
A time-reversal invariant topological insulator occupying a Euclidean half-space determines a ‘Quaternionic’ self-adjoint Fredholm family. We show...
