Self-subsidizing Mercury Remediation with Fusion Reactors

J. F. Parisi, J. Azad · 2026

Fusion reactors can permanently remediate mercury by using it as a neutron multiplier: each (n,2n) reaction reduces the neutron number towards ${}^{197}$Hg which quickly decays into stable gold, irrev…

Orbital Debris in Earth Orbit: Operations, Stability, Control, and Market Formation

Slava G. Turyshev · 2026

Orbital debris in Earth orbit is not adequately described as a static inventory problem. It is a coupled operations-stability problem governed by shell occupancy, collision kernel, breakup severity, a…

Physical manifestation of replica symmetry breaking in a quantum glass of bosons with off-diagonal disorder

Anna M. Piekarska, Tadeusz K. Kopec · 2026

Glassiness occurs when disorder and frustration cause local degrees of freedom to freeze despite the lack of long-range order. In systems of interacting bosons, such glassiness may involve a purely qu…

Towards a Refinement of Krylov Complexity: Scrambling, Classical Operator Growth and Replicas

Hugo A. Camargo, Yichao Fu, Keun-Young Kim, Yeong Han Park · 2026

We propose and test logarithmic Krylov (logK) complexity, an operator growth measure akin to Krylov complexity defined through a replica approach, as a viable probe of early-time operator scrambling w…
