Instanton dynamics in finite temperature QCD via holography
Nuclear Physics B, 2015 We investigate instantons in finite temperature QCD via Witten's holographic QCD. To study the deconfinement phase, we use the setup proposed in [1]. We find that the sizes of the instantons are stabilized at certain values both in the confinement and ...

Heavy-Meson Decay Constants: Isospin Breaking from QCD Sum Rules
EPJ Web of Conferences, 2017 Compared with lattice QCD, isospin breaking of heavy-meson decay constants from QCD sum rules agrees for D mesons but disagrees (by a factor of four) for B mesons.

Recent results on the meson and baryon spectrum from lattice QCD
EPJ Web of Conferences, 2017 Recent lattice results on the meson and baryon spectrum with a focus on the determination of hadronic resonance masses and widths using a combined basis of single-hadron and hadron-hadron interpolating fields are reviewed.

Berry Phase in Lattice QCD [PDF]
Physical Review Letters, 2016 We propose the lattice QCD calculation of the Berry phase which is defined by the ground state of a single fermion. We perform the ground-state projection of a single-fermion propagator, construct the Berry link variable on a momentum-space lattice, and calculate the Berry phase. As the first application, the first Chern number of the (2+1)-dimensional
