Maximum entropy analysis of the spectral functions in lattice QCD

- M. Asakawa, T. Hatsuda, Y. Nakahara
- Physics
- 7 November 2000

Abstract First principle calculation of the QCD spectral functions (SPFs) based on the lattice QCD simulations is reviewed. Special emphasis is placed on the Bayesian inference theory and the Maximum… Expand

Equation of State for SU(3) Gauge Theory via the Energy-Momentum Tensor under Gradient Flow

- M. Kitazawa, Takumi Iritani, M. Asakawa, T. Hatsuda, Hiroshi Suzuki
- Physics
- 25 October 2016

The energy density and the pressure of SU(3) gauge theory at finite temperature are studied by direct lattice measurements of the renormalized energy-momentum tensor obtained by the gradient flow.… Expand

Fluctuation probes of quark deconfinement

- M. Asakawa, U. Heinz, B. Muller
- Physics
- 20 June 2001

The size of the average fluctuations of net baryon number and electric charge in a finite volume of hadronic matter differs widely between the confined and deconfined phases. These differences may be… Expand

Hadronic spectral functions in lattice QCD

- Y. Nakahara, M. Asakawa, T. Hatsuda
- Physics
- 28 May 1999

QCD spectral functions of hadrons in the pseudo-scalar and vector channels are extracted from lattice Monte Carlo data of the imaginary time Green's functions. The maximum entropy method works well… Expand

Anomalous Transport Processes in Anisotropically Expanding Quark-Gluon Plasmas

- M. Asakawa, S. Bass, B. Muller
- Physics
- 24 August 2006

We derive an expression for the anomalous viscosity in an anisotropically expanding quark-gluon-plasma, which arises from interactions of thermal partons with dynamically generated color fields. The… Expand

Thermodynamics of SU (3) gauge theory from gradient flow on the lattice

- M. Asakawa, T. Hatsuda, E. Itou, M. Kitazawa, Hiroshi Suzuki
- Physics
- 29 December 2013

A novel method to study the bulk thermodynamics in lattice gauge theory is proposed on the basis of the Yang-Mills gradient flow with a fictitious time $t$. The energy density $ϵ$ and the pressure… Expand

Distribution of stress tensor around static quark–anti-quark from Yang–Mills gradient flow

- R. Yanagihara, Takumi Iritani, M. Kitazawa, M. Asakawa, T. Hatsuda
- Physics
- 15 March 2018

Abstract The spatial distribution of the stress tensor around the quark–anti-quark ( Q Q ¯ ) pair in SU(3) lattice gauge theory is studied. The Yang–Mills gradient flow plays a crucial role to make… Expand

Anomalous viscosity of an expanding quark-gluon plasma

- M. Asakawa, S. Bass, B. Muller
- Physics
- 2 February 2007

We argue that an expanding quark-gluon plasma has an anomalous viscosity, which arises from interactions with dynamically generated colour fields. The anomalous viscosity dominates over the… Expand

Hydrodynamical evolution near the QCD critical end point

- C. Nonaka, M. Asakawa
- Physics
- 18 October 2004

Phenomenologically, hydrodynamical calculations have been successful in describing global observables in ultrarelativistic heavy-ion collisions, which aim to observe the production of the quark-gluon… Expand

Anomalous viscosity of an expanding quark-gluon plasma.

- M. Asakawa, S. Bass, B. Müller
- Physics, Medicine
- Physical review letters
- 12 March 2006

We argue that an expanding quark-gluon plasma has an anomalous viscosity, which arises from interactions with dynamically generated color fields. We derive an expression for the anomalous viscosity… Expand
