Anyons and Inherently Complex F-symbols

Matthew Buican, Peter Huston, Jiannis K. Pachos·Jul 11, 2026

Anyons in $2+1$ dimensions are not only characterized by exotic braiding statistics but also by intricate fusion properties. Two anyons may fuse into multiple topological charge sectors, and associativity of fusing three anyons to produce a fixed cha...

Hamiltonian Conditions for Dark Modes in Multimode Bosonic Systems

Zuxin Wu, Shengshi Pang·Jul 11, 2026

Dark modes arise when destructive interference prevents selected bosonic degrees of freedom from coupling to environmental channels. We formulate a Hamiltonian criterion for identifying such modes in multimode bosonic systems by separating two requir...

Measurement-induced overconcentration in quantum generative models

Runzhe Mo, Bingzhi Zhang, Quntao Zhuang·Jul 11, 2026

Quantum measurement is a key resource for quantum generative learning, providing intrinsic stochasticity for generating diverse quantum samples. However, in measurement-assisted state-ensemble resampling, repeated measurements can also induce overcon...

Nonlinear particle detectors across the Rindler firewall

Matheus H. Zambianco, Eduardo Martín-Martínez·Jul 10, 2026

We investigate Unruh-DeWitt detectors coupled to composite observables of a quantum scalar field, including quadratic coupling to the field momentum and coupling to the local energy density. We develop a distributional framework for evaluating the co...

Silicon-Germanium Heterostructures with Enhanced Valley Splitting for Spin Qubits

David W. Kanaar, Efrain Martinez, Peihong Zhang +1 more·Jul 10, 2026

Achieving valley splittings well in excess of the thermal energy of electrons and avoiding valley excitations is essential for the consistent initialization, operation and readout of gate-defined Si spin qubits. In this work, we present a device-leve...

Local Determinacy of Quantum Master Equations and a Mechanical Interpretation of the Multi-Mode Jaynes-Cummings and Central Spin Models

Jaeha Lee, Miku Ishizaki·Jul 10, 2026

We propose a novel formulation of master equations for open systems wherein the evolution of a state is determined solely by its local behaviour at any point of time. Specifically, our formulation allows for a local interpretation of the workings of ...

Optimality of the free quantum evolution: the general case with nodes

Laura M. Morato·Jul 10, 2026

Extending and refining a preceding work, the free evolution of a quantum wave function, with fixed initial and final modulus, is considered in the general case where nodes are allowed. The method is based on considering a suitable simple functional r...

A complete ultrametric on von Neumann's incomplete tensor products

Andrew Lesniewski·Jul 10, 2026

We revisit von Neumann's theory of infinite tensor products of Hilbert spaces. On the set $Γ$ of equivalence classes of $C_0$-sequences, which labels the incomplete tensor products inside the complete tensor product, we introduce a natural pseudo-ult...
