17. First study of $N_f=2+1+1$ lattice QCD with physical domain-wall quarks at finite temperatures (Cancelled)

Prof. Ting-Wai Chiu (National Taiwan University)

26/06/2019, 11:05

Oral talk

Using a GPU cluster consisting of 25 units of Nvidia DGX-1 (each unit having 8*V100 interconnected by the NVLink), TWQCD collaboration has generated the first gauge ensembles of $N_f=2+1+1$ lattice QCD with physical domain-wall quarks on the $ L_x^3 \times L_t = 64^3 \times (6,8,10,12,16) $ lattices, in the temperature range $ T \simeq 200 - 550 $ MeV. The lattice spacing $a \sim 0.064 $~fm ($...

35. The chiral phase transition in (2+1)-flavor QCD

Prof. Frithjof Karsch (Universitaet Bielefeld)

26/06/2019, 11:30

Oral talk

We present recent results on the pseudo-critical and critical behavior in (2+1)-flavor QCD close to the chiral phase transition temperature.

71. QCD energy-momentum tensor using gradient flow

Dr Yusuke Taniguchi (University of Tsukuba)

26/06/2019, 11:55

Oral talk

We study the energy-momentum tensor in QCD for $N_f$ = 2+1 dynamical quarks. In order to tame violation of the translational invariance on lattice we use the gradient flow method as a non-perturbative renormalization scheme. We adopt two values for the up and down quark mass. One is the physical mass with which we measure the one point function of the energy-momentum tensor and derive the...

2. Pion condensation -chpt versus lattice

Prof. Jens Oluf Andersen (Norwegian University of Science and Technology)

26/06/2019, 12:20

Oral talk

In this talk I will discuss pion condensation and the phase diagram at finite temperature and isospin density. I will present results for the quark-meson model and chiral perturbation theory. The results for the phase diagram, pressure and equation of state are compared with recent lattice results. I will also present results for pion stars that consist of a Bose condensate of pion...
