Quantum reflection as a new signature of quantum vacuum nonlinearity [PDF]
New Journal of Physics, 2013 We show that photons subject to a spatially inhomogeneous electromagnetic field can experience quantum reflection. Based on this observation, we propose quantum reflection as a novel means to probe the nonlinearity of the quantum vacuum in the presence ...

Observation and Quantum Objectivity [PDF]
Philosophy of Science, 2012 The paradox of Wigner's friend challenges the objectivity of description in quantum theory. A pragmatist interpretation can meet this challenge by judicious appeal to decoherence.

Observation of metastability in open quantum dynamics of a solid-state system [PDF]
Nature CommunicationsMetastability is a ubiquitous phenomenon in nonequilibrium physics and classical stochastic dynamics. It arises when the system dynamics settles in long-lived states before eventually decaying to true equilibria.

Journal of Anomalous Experience and Cognition, 2022 Objective. In the research presented here, quantum measurement is conceptualized as pragmatic information transfer when an intentional observer perceives motive-relevant quantum-based outcomes. Owing to the nature of pragmatic information as described in

Emergence of the Born rule in quantum optics [PDF]
Quantum, 2020 The Born rule provides a fundamental connection between theory and observation in quantum mechanics, yet its origin remains a mystery. We consider this problem within the context of quantum optics using only classical physics and the assumption of a ...

Effective quantum observables [PDF]
Il Nuovo Cimento B, 1995 Thought experiments about the physical nature of set theoretical counterexamples to the axiom of choice motivate the investigation of peculiar constructions, e.g. an infinite dimensional Hilbert space with a modular quantum logic. Applying a concept due to BENIOFF, we identify the intrinsically effective Hamiltonians with those observables of quantum ...

Observations in quantum cosmology
Classical and Quantum Gravity, 2023 Abstract In this review, we focus on whether a canonical quantization of general relativity can produce testable predictions for cosmology. In particular, we examine how this approach can be used to model the evolution of primordial perturbations. This program of quantum geometrodynamics, first advocated by John Wheeler and Bryce DeWitt,

Observation of the Quantum Boomerang Effect
Physical Review X, 2022 A particle in an Anderson-localized system, if launched in any direction, should, on average, return to its starting point and stay there. Despite the central role played by Anderson localization in the modern understanding of condensed matter, this ...

Direct observation of quantum percolation dynamics
Nanophotonics, 2022 Percolation, describing critical behaviors of phase transition in a geometrical context, prompts wide investigations in natural and social networks as a fundamental model.
