Fractional-statistics emergence conjecture for quasihole tracer particles

About 4 years old · traced to

Fix an integer n≥2n\ge 2. Let p,μ∈Np,\mu\in\mathbb{N}, let b=N∈N\mathfrak{b}=N\in\mathbb{N}, and define

Ψqh(w;z)=(∏j=1n∏k=1N(wj−zk)p)(∏1≤k<ℓ≤N(zk−zℓ)μ∏k=1Ne−b∣zk∣2/2).\Psi_{\rm qh}(\mathbf{w};\mathbf{z})=\left(\prod_{j=1}^n\prod_{k=1}^N(w_j-z_k)^p\right)\left(\prod_{1\leq k<\ell\leq N}(z_k-z_\ell)^\mu\prod_{k=1}^N e^{-\mathfrak{b}|z_k|^2/2}\right).

Let Φ∈C0(R2n)\Phi\in C^0(\mathbb{R}^{2n}) have support in {∣x∣≤d}×n\{ |x|\leq d\}^{\times n} for some d<μd<\sqrt{\mu}, and assume that for some CΦ>0C_\Phi>0 and β>0\beta>0,

∣Φ(y)∣≤CΦ∣yi−yj∣β|\Phi(\mathbf{y})|\leq C_\Phi |y_i-y_j|^\beta

for all i≠ji\ne j. For any j∈{1,…,n}j\in\{1,\dots,n\}, and for sufficiently large κ>0\kappa>0, define

Ajtot(y)=−(q−pμ)byj⊥−p2μ∑ℓ≠j(yj−yℓ)⊥∣yj−yℓ∣2.\mathbf{A}^{\rm tot}_j(\mathbf{y})=-\left(q-\frac{p}{\mu}\right)\mathfrak{b}y_j^\perp-\frac{p^2}{\mu}\sum_{\ell\ne j}\frac{(y_j-y_\ell)^\perp}{|y_j-y_\ell|^2}.

Fractional-statistics emergence conjecture. As N→+∞N\to+\infty, the identity

∫R2(N+n)∣(−i∇yj−qbyj⊥)ΨΦ∣2=2bpμ+∫R2n∣(−i∇yj+Ajtot(y))Φ∣2+Errors\int_{\mathbb{R}^{2(N+n)}}\left|\left(-\mathrm{i}\nabla_{y_j}-q\mathfrak{b}y_j^\perp\right)\Psi_\Phi\right|^2=2\mathfrak{b}\frac{p}{\mu}+\int_{\mathbb{R}^{2n}}\left|\left(-\mathrm{i}\nabla_{y_j}+\mathbf{A}^{\rm tot}_j(\mathbf{y})\right)\Phi\right|^2+\mathrm{Errors}

should hold. This conjecture extends the paper's statistics-transmutation result from integer to fractional statistics, motivated by the fractional quantum Hall effect; the notation ΨΦ\Psi_\Phi is inherited from the preceding definition in the paper, and the source does not state a quantified form of the error term.
