Towards First Quantisation Formalism for AKSZ Theories

Leon Menger, Pavel Mnev

The paper develops a one‑dimensional AKSZ model on graphs that serves as a first‑quantisation picture for a given AKSZ field theory, showing how its partition function reproduces t…

Congruence of Dirac operators with applications to generalized MIT bag models

Joaquim Duran, Konstantin Pankrashkin

The paper introduces a simple congruence transformation that shifts coupling parameters for Dirac operators with shell interactions, and uses it to derive new results on the self‑a…

Lee-Yang Zeros And Particle Fluctuations

Mohamed El Hedi Bahri, Ian Jauslin, Joel L. Lebowitz

The paper proves that if Lee–Yang zeros of the grand‑canonical partition function stay away from a positive real fugacity, then in the thermodynamic limit the pressure and its deri…
