32. 3D Pion crystal from the chiral anomaly

Geraint Evans (Institute of Physics, Academia Sinica)

Talk

Including the effects of the chiral anomaly within Chiral Perturbation Theory at finite baryon chemical potential, it has been shown that neutral pions form an inhomogeneous phase dubbed the "Chiral Soliton Lattice" (CSL) above a certain critical magnetic field. Above a second (higher) critical field, the CSL becomes unstable to fluctuations of charged pions, implying they condense. I will...

66. Inhibition of splitting of confining and chiral transition by rotation.

We will discuss the effect of rotation on the confining and chiral properties of QCD using the linear sigma model coupled to the Polyakov loop. Enforcing the causality constraint by the spectral boundary conditions we obtain the phase diagram at finite temperature, baryon density, and angular frequency. At nonrotating limit we observe a splitting between the chiral and confining transitions...

78. Quark spin correlations in relativistic heavy ion collisions (online)

On-line talk

The observation of the vector meson's global spin alignment by the STAR Collaboration reveals that strong spin correlations may exist for quarks and antiquarks in relativistic heavy-ion collisions in the normal direction of the reaction plane. We propose a systematic method to describe such correlations in the quark matter. The correlations can be classified as local and long range types. We...

17. Mixed inhomogeneous phase in vortical gluon plasma from lattice simulation (online)

Artem Roenko (JINR)

On-line talk

Using first-principle numerical simulations, we find a new spatially inhomogeneous phase in rigidly rotating gluon plasma. This mixed phase simultaneously possesses both confining and deconfining phases in thermal equilibrium. Unexpectedly, the local critical temperature of the phase transition at the rotation axis does not depend on the angular frequency within a few percent accuracy. An...

37. Chiral symmetry breaking and restoration for an accelerated and rotated observer (online)

Zhibin Zhu (Fudan university)

7/24/24, 9:30 AM

On-line talk

In the relativistic heavy ion collision experiment, there exist a large acceleration and rapid rotation in the non-central collision which can be considered as a system with acceleration and rotation. According to the Hawking-Unruh effect, the accelerated observer sees himself in a system with Unruh temperature $T/2\pi$. And the color glass condensate picture predicts that in heavy ion...

33. QCD phase diagram in the $T-eB$ plane for pion masses beyond its physical value

Aminul Islam Chowdhury

Talk

It is interesting to observe the effect of the pion mass beyond its physical value on the QCD phase diagram in the $T-eB$ plane. The fate of the inverse magnetic catalysis (IMC) and the behaviour of $T_{\rm CO}$ beyond the physical point are of particular interest. Lattice QCD studies hint at a possible elimination of IMC effects with increasing pion mass. We aim to understand the entire...
