Abstract.Quantum Energy Inequalities (QEIs) are results which limit the extent to which the smeared renormalized energy density of the quantum field can be negative, when averaged along a timelike curve or over a more general timelike submanifold in spacetime. On globally hyperbolic spacetimes the minimally-coupled massive quantum Klein–Gordon field is known to obey a ‘difference’ QEI that depends on a reference state chosen arbitrarily from the class of Hadamard states. In many spacetimes of…

Quantum weak energy inequalities (QWEIs) are results which limit the extent to which the smeared renormalized energy density of a quantum field can be negative. On globally hyperbolic spacetimes the
Quantum strong energy inequalities
Quantum energy inequalities (QEIs) express restrictions on the extent to which weighted averages of the renormalized energy density can take negative expectation values within a quantum field theory.
Averaged null energy condition and quantum inequalities in curved spacetime
The Averaged Null Energy Condition (ANEC) states that the integral along a complete null geodesic of the projection of the stress-energy tensor onto the tangent vector to the geodesic cannot be
Quantum inequality in spacetimes with small curvature
Quantum inequalities bound the extent to which weighted time averages of the renormalized energy density of a quantum field can be negative. They have mostly been proved in flat spacetime, but we
Lectures on quantum energy inequalities
Quantum field theory violates all the classical energy conditions of general relativity. Nonetheless, it turns out that quantum field theories satisfy remnants of the classical energy conditions,
Quantum Energy Inequalities
Quantum Energy Inequalities (QEIs) are lower bounds on local averages of energy densities and related quantities in quantum field theory (QFT). They replace the classical energy conditions of
A Class of Almost Equilibrium States in Robertson-Walker Spacetimes
In quantum field theory in curved spacetimes the construction of the algebra of observables of linear fields is today well understood. However, it remains a non-trivial task to construct physically
Algebraic Quantum Field Theory in Curved Spacetimes
This chapter sets out the framework of algebraic quantum field theory in curved spacetimes, based on the idea of local covariance. In this framework, a quantum field theory is modelled by a functor
Local Thermal Equilibrium States and Quantum Energy Inequalities
Abstract.In this paper we investigate the energy distribution of states of a linear scalar quantum field with arbitrary curvature coupling on a curved spacetime which fulfill some local thermality
Quantum energy inequalities and local covariance II: categorical formulation
We formulate quantum energy inequalities (QEIs) in the framework of locally covariant quantum field theory developed by Brunetti, Fredenhagen and Verch, which is based on notions taken from category

A Quantum Weak Energy Inequality¶for Dirac Fields in Curved Spacetime
Abstract: Quantum fields are well known to violate the weak energy condition of general relativity: the renormalised energy density at any given point is unbounded from below as a function of the
Quantum energy inequalities and local covariance. I. Globally hyperbolic spacetimes
We begin a systematic study of quantum energy inequalities (QEIs) in relation to local covariance. We define notions of locally covariant QEIs of both “absolute” and “difference” types and show that
Quantum energy inequalities for the non-minimally coupled scalar field
In this paper, we discuss local averages of the energy density for the non-minimally coupled scalar quantum field, extending a previous investigation of the classical field. By an explicit example,
Quantum inequalities in curved two-dimensional spacetimes
In quantum field theory there exist states in which the energy density is negative. It is important that these negative energy densities satisfy constraints, such as quantum inequalities, to minimize

Quantum energy inequalities (QEIs) are state-independent lower bounds on weighted averages of the stress-energy tensor, and have been established for several free quantum field models. We present
