Fluctuations of conserved charges at finite temperature from lattice QCD
Szabolcs Borsanyi, Zoltan Fodor, Sandor D. Katz +3
We present the full results of the Wuppertal-Budapest lattice QCD collaboration on flavor diagonal and non-diagonal quark number susceptibilities with 2+1 staggered quark flavors,…
Error Bounds for the Sign Function
Andreas Frommer, Karsten Kahl, Thomas Lippert +1
The Overlap operator fulfills the Ginsparg-Wilson relation exactly and therefore represents an optimal discretization of the QCD Dirac operator with respect to chiral symmetry. Whe…
Event-based simulation of interference with alternatingly blocked particle sources
K. Michielsen, S. Mohanty, L. Arnold +1
We analyze the predictions of an event-based corpuscular model for interference in the case of two-beam interference experiments in which the two sources are alternatingly blocked.…
Quantum simulations and experiments on Rabi oscillations of spin qubits: intrinsic {\sl vs} extrinsic damping
H. De Raedt, B. Barbara, S. Miyashita +3
Electron Paramagnetic Resonance experiments show that the decay of Rabi oscillations of ensembles of spin qubits depends noticeably on the microwave power and more precisely on the…
Einstein-Podolsky-Rosen-Bohm laboratory experiments: Data analysis and simulation
H. De Raedt, K. Michielsen, F. Jin
Data produced by laboratory Einstein-Podolsky-Rosen-Bohm (EPRB) experiments is tested against the hypothesis that the statistics of this data is given by quantum theory of this tho…
Nucleon sigma terms for 2+1 quark flavours
R. Horsley, Y. Nakamura, H. Perlt +7
QCD lattice simulations yield hadron masses as functions of the quark masses. From the gradients of the hadron masses the sigma terms can then be determined. We consider here dynam…
Bridging the gap: disk formation in the Class 0 phase with ambipolar diffusion and Ohmic dissipation
Wolf B. Dapp, Shantanu Basu, Matthew W. Kunz
Context: Ideal MHD simulations have revealed catastrophic magnetic braking (MB) in the protostellar phase, which prevents the formation of a centrifugal disk around a nascent proto…
Strangeness Contribution to the Proton Spin from Lattice QCD
Gunnar S. Bali, Sara Collins, Meinulf Gockeler +8
We compute the strangeness and light-quark contributions Delta s, Delta u and Delta d to the proton spin in nf=2 lattice QCD at a pion mass of about 285 MeV and at a lattice spacin…
A lattice study of the strangeness content of the nucleon
G. S. Bali, S. Collins, M. Gockeler +9
We determine the quark contributions to the nucleon spin Delta s, Delta u and Delta d as well as their contributions to the nucleon mass, the sigma-terms. This is done by computing…
The finite temperature QCD transition in external magnetic fields
G. S. Bali, F. Bruckmann, G. Endrodi +5
The effect of an external magnetic field on the finite temperature transition of QCD is studied. We measure thermodynamic observables including the quark condensates and susceptibi…
QCD thermodynamics with Wilson fermions
Szabolcs Borsanyi, Zoltan Fodor, Christian Hoelbling +6
QCD is investigated at finite temperature using Wilson fermions in the fixed scale approach. A 2+1 flavor stout and clover improved action is used at four lattice spacings allowing…
The QCD phase diagram for external magnetic fields
G. S. Bali, F. Bruckmann, G. Endrodi +5
The effect of an external (electro)magnetic field on the finite temperature transition of QCD is studied. We generate configurations at various values of the quantized magnetic flu…

We determine the strangeness and light quark fractions of the nucleon mass by computing the quark line connected and disconnected contributions to the matrix elements m_q <N|qbar q…
Hyperon sigma terms for 2+1 quark flavours
R. Horsley, Y. Nakamura, H. Perlt +7
QCD lattice simulations determine hadron masses as functions of the quark masses. From the gradients of these masses and using the Feynman-Hellmann theorem the hadron sigma terms c…
Sigma term and strangeness content of octet baryons
S. Durr, Z. Fodor, T. Hemmert +11
By using lattice QCD computations we determine the sigma terms and strangeness content of all octet baryons by means of an application of the Hellmann-Feynman theorem. In addition…

G. Bali, S. Collins, S. Durr +18
We study the spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states. We use two sets of gauge configurations, one set fro…
Correlations in sequences of generalized eigenproblems arising in Density Functional Theory
Edoardo Di Napoli, Stefan Blügel, Paolo Bientinesi
Density Functional Theory (DFT) is one of the most used ab initio theoretical frameworks in materials science. It derives the ground state properties of a multi-atomic ensemble dir…
The ratio m_c/m_s with Wilson fermions
Stephan Durr, Giannis Koutsou
We determine the quark mass ratio m_c/m_s on the lattice, using Wilson-type fermions. Configurations with N_f=2 dynamical clover-improved fermions by the QCDSF collaboration are us…

With first-principles DFT calculations, the interaction between graphene and SiO2 surface has been analyzed by constructing the different configurations based on α-quartz and crist…
Topology of dynamical lattice configurations including results from dynamical overlap fermions
Falk Bruckmann, Nigel Cundy, Florian Gruber +2
We investigate how the topological charge density in lattice QCD simulations is affected by violations of chiral symmetry caused by the fermion action. To this end we compare latti…

S. Durr, Z. Fodor, C. Hoelbling +8
Indirect CP violation in K \rightarrow ππ decays plays a central role in constraining the flavor structure of the Standard Model (SM) and in the search for new physics. For many ye…
