Momentum coupling of classical atoms
Andras Suto
A new method, dual-space cluster expansion, is proposed to study classical phases transitions in the continuum. It relies on replacing the particle positions as integration variabl…
Infinite cycles of interacting bosons
Andras Suto
In the first-quantized description of bosonic systems permutation cycles formed by the particles play a fundamental role. In the ideal Bose gas Bose-Enstein condensation (BEC) is s…
Bose-Einstein condensation of interacting bosons: A two-step proof
Andras Suto
We prove two equilibrium properties of a system of interacting atoms in three or higher dimensional continuous space. (i) If the particles interact via pair potentials of a nonnega…
Condensation of interacting bosons
Andras Suto
In this third paper of a series that started with arXiv:2106.10032 [math-ph] and continued with arXiv:2108.02659 [math-ph] we show that in dimensions at low temperatures…
Simultaneous occurrence of off-diagonal long-range order and infinite permutation cycles in systems of interacting atoms
Andras Suto
Based on the paper "Fourier formula for quantum partition functions", arXiv:2106.10032 [math-ph], we show that in an infinite system of identical bosons interacting via a positive-…
Fourier formula for quantum partition functions
Andras Suto
Fourier expansion of the integrand in the path integral formula for the partition function of quantum systems leads to a deterministic expression which, though still quite complex,…
