High-temperature limit of the confining phase.
The deconfining transition in non-Abelian gauge theory is known to occur by a condensation of Wilson lines. By expanding around an appropriate Wilson line background, it is possible at large N to analytically continue the confining phase to arbitrarily high temperatures , reaching a weak coupling confinement regime. This is used to study the high temperature partition function of an SU(N) elect...
متن کاملBringing entanglement to the high temperature limit.
Decoherence due to contact with a hot environment typically restricts quantum phenomena to the low temperature limit, k_{B}T/ℏω≪1 (ℏω is the typical energy of the system). Here we report the existence of a nonequilibrium state for two coupled, parametrically driven, dissipative harmonic oscillators which, contrary to generalized intuition, has stationary entanglement at high temperatures. This ...
متن کاملYang-Lee Edge in the High-Temperature Limit
in the complex z = e -2H plane, where H is the reduced external magnetic field. At infinite temperature (T = m) the spins are noninteracting and the partition function reduces to (z 1í2 + z-ìë)~, where N is the total number of spins. The zeros are therefore N-fold degenerate at 8 = a. As the temperature is lowered, the zeros spread into an arc segment of the unit circle centered about 8 = 7r an...
متن کاملClassical Limit for Scalar Fields at High Temperature
We study real-time correlation functions in scalar quantum field theories at temperature T = 1/β. We show that the behaviour of soft, long wave length modes is determined by classical statistical field theory. The loss of quantum coherence is due to interactions with the soft modes of the thermal bath. The soft modes are separated from the hard modes by an infrared cutoff Λ ≪ 1/(¯ hβ). Integrat...
متن کاملHigh-Temperature Limit of Landau-Gauge Yang-Mills Theory
The infrared properties of the high-temperature limit of Landau-gauge Yang-Mills theory are investigated. In a first step the high-temperature limit of the Dyson-Schwinger equations is taken. The resulting equations are identical to the Dyson-Schwinger equations of the dimensionally reduced theory, a three-dimensional Yang-Mills theory coupled to an effective adjoint Higgs field. These equation...
