Vor einem Tag · Indeed, even if the entropy of the vacuum in Quantum Field Theory is zero, if one divides the space into parts, as the horizon of the black hole does, then the vacuum, when restricted in a region of space, say the exterior of the black hole, carries some entropy which is the entanglement entropy between the interior and the exterior of the black hole.

17. Apr. 2024 · We develop a novel framework for describing quantum fluctuations in field theory, with a focus on cosmological applications. Our method uniquely circumvents the use of operator/Hilbert-space formalism, instead relying on a systematic treatment of classical variables, quantum fluctuations, and an effective Hamiltonian.
23. Apr. 2024 · This paper analyzes the effective field theory perspective on modern physics through the lens of the quantum theory of gravitational interaction. The historical part argues that the search for a theory of quantum gravity stimulated the change in outlook that characterizes the modern approach to the standard model of particle physics ...
Vor 5 Tagen · The quantum theory of gravitation, effective field theories and strings: Past and present. Gravity is one of four fundamental interactions. The most precise description of this force is still ...
Vor 2 Tagen · Werner Nahm. The overlap of Srinivasa Ramanujan's work with quantum field theory is discussed. A mathematically natural axiom for euclidean quantum field theories is proposed.
