We present an overview of recent results from the CP-PACS computer on the quenched light hadron spectrum and an on-going two-flavour full QCD study. We find that our quenched hadron mass results are compatible with the mass formulae predicted by quenched chiral perturbation theory, which we adopt in our final analysis. Quenched hadron masses in the continuum limit show unambiguous and systematic deviations from experiment. For our two-flavour full QCD simulation we present preliminary results on the light hadron spectrum, quark masses and the static potential. The question of dynamical sea quark effects in these quantities is discussed.

“…Particle production [1] with a thermal spectrum from black holes [2,3,4], moving mirrors [5], accelerated detectors [6], observers in de Sitter Universe [7] and certain cosmological spacetimes [8] has been a subject of continual discussion since the mid-seventies because of its extraordinary nature and its basic theoretical value. The mainstream approach to these problems relied on thermodyamic arguments [9,10], finite temperature field theory techniques [11,12,13], or geometric constructions (event horizon as a global property of spacetime) [14], or pairwise combinations thereof. The status of work on quantum field theory in curved spacetimes up to 1980 can be found in [15].…”

In analyzing the nature of thermal radiance experienced by an accelerated observer (Unruh effect), an eternal black hole (Hawking effect) and in certain types of cosmological expansion, one of us proposed a unifying viewpoint that these can be understood as arising from the vacuum fluctuations of the quantum field being subjected to an exponential scale transformation in these systems. This viewpoint, together with our recently developed stochastic theory of particle-field interaction understood as quantum open systems described by the influence functional formalism, can be used effectively to address situations where the spacetime possesses an event horizon only asymptotically, or none at all. Examples studied here include detectors moving at uniform acceleration only asymptotically or for a finite time, a moving mirror, and a two-dimensional collapsing mass. We show that in such systems radiance indeed is observed, albeit not in a precise Planckian spectrum. The deviation therefrom is determined by a parameter which measures the departure from uniform acceleration or from exact exponential expansion. These results are expected to be useful for the investigation of non-equilibrium black hole thermodynamics and the linear response regime of backreaction problems in semiclassical gravity.

“…Such a state with an extra light dynamical quark pair has poor overlap with the flux-tube state, so it is presumably revealed only after evolution to a very large temporal separation. An improved Wilson-loop-style determination of the heavy quark potential in full QCD would employ a variational superposition of the flux-tube and two-heavy-meson states [10,11]. The Polyakov loop approach, on the other hand, although limited in practical application to temperatures close to or above T c , builds in no prejudices about the structure of the static-pair ground state wave function.…”
