Stochastic Quantum Information Geometry and Speed Limits at the Trajectory Level
Pedro B. Melo, Pedro V. Paraguassú, SÃlvio M. Duarte Queirós +3
In quantum metrology, precision is typically characterized by an ensemble-averaged quantity, the quantum Fisher information (QFI), which averages over the fluctuations of individua…
Quantum percolation in honeycomb lattices under random spin-orbit coupling
W. S. Oliveira, Julián Faúndez, Welles Morgado
We investigate quantum percolation in a honeycomb lattice with site dilution and random spin-orbit coupling. Using exact diagonalization combined with finite-size scaling analysis,…
Tilings of a bounded region of the plane by maximal one-dimensional tiles
Eduardo J. Aguilar, Valmir C. Barbosa, Raul Donangelo +2
We study the tiling of a two-dimensional region of the plane by -cell one-dimensional tiles, or -mers. Unlike previous studies, which typically allowed for one single value o…
Impact of periodic thermal driving on heat fluctuations in a harmonic system
Felipe P. Abreu, Welles A. M. Morgado
The thermodynamics of mesoscopic systems driven by time-varying temperatures is crucial for understanding biological systems, designing nanoscale engines, and performing micro-part…
Thermodynamic interpretation to Stochastic Fisher Information and Single-Trajectory Speed Limits
Pedro B. Melo, Fernando Iemini, Diogo O. Soares-Pinto +2
The Fisher information (FI) metric is a Riemannian metric that allows a geometric treatment of stochastic thermodynamics, introducing the possibility of computing thermodynamic len…
Classical Geometric Fluctuation Relations
Pedro B. Melo, SÃlvio M. Duarte Queirós, Diogo O. Soares-Pinto +1
Fisher Information (FI) is a quantity ubiquitously measured in such varied areas like metrology, machine learning, and biological complexity. Mathematically, it represents a lower…
