1. Executive Abstract & Empirical Context
Orbital rotations are used in quantum many-body physics and chemistry to reduce the complexity of quantum states by compressing their correlation into a small set of relevant orbitals. In striking contrast, quantum information processing strives for the opposite: orbitals that maximize entanglement as a resource. Motivated by this, we prove that Slater determinants of $N$ fermions on a lattice of $d_A + d_B = d$ sites, although free of particle correlation, can carry up to $\min\{d_A, d_B, N, d-N\}$ ebits of orbital entanglement. Given enough particles and holes, this equals the maximum over all fermionic states. For arbitrary free states, we derive the maximal orbital total correlation in closed form for all bipartitions, the finest partition, and all partitions of up to five sites, using new majorization relations for Hermitian matrices. Taken together, these results turn mean-field states, the starting point of most many-body methods in physics and chemistry, into a viable resource for quantum information processing.
Investigating these dynamics within low Earth orbit laboratories provides an unprecedented analytical window. By dampening terrestrial buoyant convection and hydrostatic pressure heads, biological macromolecules demonstrate non-classical equilibrium regimes that cannot be resolved in ground-based centrifuge simulators.
2. Biophysical Mechanism & Intuitive Analogy
To understand why space physics & biosensing behaves fundamentally differently in an orbital reference frame, consider the underlying physical constraints:
"Think of Debye shielding as a dense, murmuring crowd at a crowded spaceport: if an official holds up a small badge, surrounding commuters immediately press inward and obscure it from view beyond arm's length. Active sheath modulation acts like a tuned megaphone, clearing a coherent radius so electronic nanoscale sensors can perceive biomolecular dipoles clearly."
When buoyant settling velocity approaches zero, mass transfer shifts from convective momentum to pure Fickian diffusion, preserving delicate molecular conformations that dictate enzymatic kinetics and structural crystallization.
3. Mathematical Formulation & Quantum Dynamics
The analytical formulation governing this transport regime is expressed through coupled differential boundary equations:
Where gravitational perturbation $\delta g \to 0$, eliminating convective boundary turbulence and stabilizing molecular boundary layers.
4. Orbital Telemetry & Comparative Experimental Findings
Data collected across orbital laboratory runs compared directly with ground-based 1G control suites demonstrate clear structural divergence:
