DOI: 10.1007/jhep07(2018)167
Abstract: A bstractWe propose an observable which involves measuring the properties (transverse momentum ph⊥ and energy fraction zh) of an identified hadron inside a groomed jet. The jet is identified with an anti-kT/CA algorithm and is… read more here.

Abstract: Abstract We compute the contribution of twist-2 and twist-3 parton distribution functions to the small-b expansion for transverse momentum dependent (TMD) distributions at all powers of b. The computation is done by the twist-decomposition method… read more here.

DOI: 10.1103/physrevb.102.014422
Abstract: The traditional bulk Rashba effect predicts spin-orbit coupling induced wave-vector-dependent spin splitting between energy bands in nonmagnetic solids that lack spatial inversion symmetry. The authors show here how the violation of magnetic symmetry leads instead… read more here.

DOI: 10.1103/physrevb.97.165416
Abstract: Despite their fundamental role in determining material properties, detailed momentum-dependent information on the strength of electron-phonon and phonon-phonon coupling (EPC and PPC, respectively) across the entire Brillouin zone (BZ) has proved difficult to obtain. Here… read more here.

DOI: 10.1103/physrevb.99.165134
Abstract: Computing momentum-dependent susceptibilities in the dynamical mean-field theory (DMFT) requires solving the Bethe-Salpeter equation, which demands large computational cost. Exploiting the strong-coupling feature of local fluctuations, we derive a simplified formula that can be solved… read more here.

DOI: 10.1103/physrevlett.129.082002
Abstract: To calculate the transverse-momentum-dependent parton distribution functions (TMDPDFs) from lattice QCD, an important goal yet to be realized, it is crucial to establish a viable nonperturbative renormalization approach for linear divergences in the corresponding Euclidean… read more here.
