Nonperturbative Effects in Energy Correlators: From Characterizing Confinement Transition to Improving $α_s$ Extraction

Energy correlators provide a powerful observable to study fragmentation dynamics in QCD. We demonstrate that the leading nonperturbative corrections for projected $N$-point energy correlators are described by the same universal parameter for any $N ...

Kinetics and thermodynamics of electron transfer in debye solvents: An analytical and nonperturbative reduced density matrix theory

, 2006
A nonperturbative electron transfer rate theory is developed on the basis of reduced density matrix dynamics, which can be evaluated readily for the Debye solvent model without further approximation.

Unruh-De Witt detectors, Bell-CHSH inequality and Tomita-Takesaki theory

Journal of High Energy Physics
The interaction between Unruh-De Witt spin 1/2 detectors and a real scalar field is scrutinized by making use of the Tomita-Takesaki modular theory as applied to the Von Neumann algebra of the Weyl operators.

Nonperturbative region of effective strong coupling

, 2013
In the framework of Poincaré covariant quark model the behavior of running coupling constant $α_{s}\left(Q^{2}\right)$ is considered in $Q < 1 \mbox{GeV}$ region. An analysis was carried out for pseudoscalar and vector mesons with lepton decay constants, masses (obtained from model dependent) and nucleon spin rules required to match their ...

Nonperturbative effects in second harmonic generation

Second-harmonic generation (SHG) is a quintessential probe of inversion symmetry breaking in condensed matter. While perturbative $χ^{(2)}$ processes are well-documented, the nonperturbative regime under intense driving remains largely unexplored. In this Letter, we develop a nonperturbative Floquet-Keldysh theory to describe SHG in two-band systems ...

Studies of nonperturbative quantum electrodynamics

Studies of nonperturbative quantum electrodynamics. In order to test fundamental quantum field theories, which underlie all physical phenomena from galaxy formation to the behaviour of biological system, it is necessary to be able to solve these theories

Nonperturbative QCD Vacuum Effects in Nonlocal Quark Dynamics

, 2007
A straightforward calculation reveals the essentially nonlocal character of the leading heavy Q ¯ Q interaction arising from nonperturbative gluon field correlations in the model of a fluctuating QCD vacuum.
