86. A density-of-states approach to numerical computations in Lattice Gauge Theories

Biagio Lucini (Swansea University)

09/03/2016, 16:30

In Lattice Gauge Theories, Monte Carlo calculations often rely on the concept of importance sampling, whereby configurations are generated according to their Boltzmann probability distribution. While this approach is very efficient at computing vacuum expectation values of observables and quantities that can be derived from the latter (e.g. masses of particles), it leads to spectacular...

91. Finite density QFT from a density-of-states perspective

Kurt Langfeld (Plymouth University)

For more than three decades, finite density quantum field theories have evaded first principle Monte-Carlo simulations due to the notorious sign-problem. The recent years have seen some remarkable progress towards the understanding of cold and dense quantum matter. The density-of-states approach aims to calculate the probability distribution of the imaginary part of the action. The...

67. QCD with chiral chemical potential: models vs. lattice

Alexander Andrianov (Saint Petersburg State University)

QCD with chiral(axial) chemical potential will be reconstructed with the help of effective low energy Lagrangians and different models of NJL type. Their thermodynamic properties will be confronted to lattice predictions. Possible signatures of chiral imbalance will be guessed.

78. Magnetic properties in the inhomogeneous chiral phase

Ryo Yoshiike (Kyoto university)

We study the magnetic properties of the inhomogeneous chiral phase, considering the “dual chiral density wave (DCDW)”, where both scalar and pseudoscalar condensates are spatially modulated. The response of quark matter to a tiny external magnetic field is investigated to show the spontaneous magnetization in the DCDW phase. In an external magnetic field, the energy spectrum of quarks becomes...

103. Pion-pion scattering and the timelike pion form factor from Lattice QCD

Ben Hörz

The calculation of infinite-volume hadron-hadron scattering amplitudes from Lattice QCD simulations requires precisely determined finite-volume energy spectra. This required level of precision is achieved using an efficient algorithm to treat the physically important low-lying modes of quark propagation. We show results for elastic pion-pion scattering amplitudes from simulations with...
