Thermal fading of the 1/k4 tail of the momentum distribution induced by the hole anomaly

Year: 2024

Type: article

Abstract: A thermal fading of the quantum behavior in the large-momenta and short-distance correlations is predicted for temperatures above the anomaly threshold, by unveiling the connection between excitations, thermodynamics, and correlations in many-body systems. An analytic high-momentum tail of the particle distribution, which is valid for any interaction strength and temperature, is proposed.
