Dynamical classical-field limit of Bosonic Gibbs states: Renormalized Hartree NLS correlations in 2D and 3D

Phan Thành Nam, Rongchan Zhu, Xiangchan Zhu

In this paper we derive the time-dependent correlation functions of the renormalized Hartree NLS equation on the torus $T^{d}$ , $d = 2, 3$ , from the corresponding bosonic many-b…

Derivation of Gibbs measure from Gibbs state with the fractional Bessel interaction in Two Dimensions

Phan Thành Nam, Rongchan Zhu, Xiangchan Zhu

We derive the classical Gibbs measure on $T^{2}$ associated with the fractional Bessel interaction potential $v_{β} (k) = ⟨ k ⟩^{- β}$ from a renormalized gra…

$Φ_{3}^{4}$ Theory from many-body quantum Gibbs states

Phan Thành Nam, Rongchan Zhu, Xiangchan Zhu

We derive the $Φ_{3}^{4}$ measure on the torus as a rigorous limit of the quantum Gibbs state of an interacting Bose gas. To be precise, starting from many-body quantum mechanics, wher…
