Floquet group theory and its application to selection rules in harmonic generation. [PDF]

Nat Commun, 2019
Symmetry is one of the most generic and useful concepts in science, often leading to conservation laws and selection rules. Here we formulate a general group theory for dynamical symmetries (DSs) in time-periodic Floquet systems, and derive their ...

Towards double parton distributions from first principles using Large Momentum Effective Theory

Journal of High Energy Physics, 2023
In double parton scattering (DPS), two partonic collisions take place between one pair of colliding hadrons. The effect of DPS can be significant for precision measurements due to the additional radiation from secondary partonic collisions, and ...

One-loop jet functions by geometric subtraction

Journal of High Energy Physics, 2020
In factorization formulae for cross sections of scattering processes, final-state jets are described by jet functions, which are a crucial ingredient in the resummation of large logarithms.

The Coulomb and Higgs branches of N $$ \mathcal{N} $$ = 1 theories of Class S k $$ {\mathcal{S}}_k $$

Journal of High Energy Physics, 2021
Even though for generic N $$ \mathcal{N} $$ = 1 theories it is not possible to separate distinct branches of supersymmetric vacua, in this paper we study a special class of N $$ \mathcal{N} $$ = 1 SCFTs, these of Class S k $$ {\mathcal{S}}_k $$ for which

Color Centers in Hexagonal Boron Nitride Monolayers: A Group Theory and Ab Initio Analysis [PDF]

, 2017
We theoretically study physical properties of the most promising color center candidates for the recently observed single-photon emissions in hexagonal boron nitride (h-BN) monolayers.

The Hopf algebra structure of the R∗-operation

Journal of High Energy Physics, 2020
We give a Hopf-algebraic formulation of the R ∗ -operation, which is a canonical way to render UV and IR divergent Euclidean Feynman diagrams finite. Our analysis uncovers a close connection to Brown’s Hopf algebra of motic graphs.

Discrete symmetries and efficient counting of operators

Journal of High Energy Physics, 2023
We present DECO (“Discrete and Efficient Counting of Operators”), an implementation of the Hilbert series to enumerate subleading operator bases for SMEFT-like EFTs with symmetry groups as typically found in flavour and BSM physics.

Trinion conformal blocks from topological strings

Journal of High Energy Physics, 2020
In this paper we investigate the relation between conformal blocks of Liouville CFT and the topological string partition functions of the rank one trinion theory T 2.

Screw and Lie group theory in multibody kinematics [PDF]

Multibody system dynamics, 2017
After three decades of computational multibody system (MBS) dynamics, current research is centered at the development of compact and user-friendly yet computationally efficient formulations for the analysis of complex MBS.

Screw and Lie group theory in multibody dynamics [PDF]

Multibody system dynamics, 2017
Screw and Lie group theory allows for user-friendly modeling of multibody systems (MBS), and at the same they give rise to computationally efficient recursive algorithms.
