Weak-value amplification after Aharonov and Vaidman (1990): resource tradeoffs, domain of validity, and optimal pointer-function bounds
Completing the phase-uncertainty picture of loss of two-path interference: noncommuting path phases, environment-modified path selection, and harmonic-dependent dephasing in realistic many-body environments
Quantitative validity conditions, postselection cost, and feasibility of postselected superpositions of time evolutions (the quantum time-translation machine program)
General domain of applicability of the quantum averages of weak values (QAWV) framework: mixed and complex apparatus priors, multi-trajectory classical correspondence, quantitative robustness bounds for eccentric weak values, and the validity domains of the framework's approximations
Remaining open problems of the Aharonov–Casher effect for neutral magnetic particles: condensed-matter realization, screening and medium effects, and the topological character of the phase
The planckon problem: deriving stable Planck-mass black-hole remnants from quantum gravity
Completing the Aharonov-Kaufherr quantum-reference-frame program: the full three-dimensional separation of internally measurable variables and the relativistic extension
Physical consequences of disembodied quantum properties: gravitation, thermodynamics, probe interactions, and scalable realization of the quantum Cheshire Cat
Completing the generalized-state description of a quantum system between two measurements: weak-vector constraints, mixed generalized states, the weak–strong measurement converse for general observables, and definite values of non-commuting observables
Corrections and domain of validity of the quantum source treatment of the Aharonov-Bohm effect: non-adiabatic source dynamics, induced fields, back-reaction, and quantum fluctuations beyond the 1961 approximations
