Dynamics of Quantum Many Body Systems Far From Thermal
... We start the discussion from a very general and qualitative definition of what thermal equilibrium is. We could say that a macroscopic system is said to be in thermal equilibrium when • its state (physical properties) is defined in terms of a unique set of intensive and extensive variables which do ...

Quantum Field Theory
... where δ is numerically equal to a Kronecker delta. One may also check that the derivative transforms as shown in (1.6). If we have a function φ(x) which depends only on x via the Lorentz invariant xµ xµ , then the combination ∂µ ∂ µ φ(x) is Lorentz invariant. 1.5. The mass shell condition Energy and ...

The great elasticity of such medium in relation to the mutual shift of etherons caused by powerful forces of the electric interaction and the next-to-nothing inertance caused by very little mass of ether particles provide for spreading different disturbances in the ether medium at a huge but ultima ...

Progress In N=2 Field Theory
... The very notion of ``what is a quantum field theory’’ is evolving… It no longer suffices just to know the correlators of all local operators. Extended ``operators’’ or ``defects’’ have been playing an increasingly important role in recent years in quantum field theory. Defects are local disturbances ...
