Quantum Superposition States of Bose-Einstein Condensates [PDF]

open access: yes, 1997
We propose a scheme to create a macroscopic ``Sch\"odinger cat'' state formed by two interacting Bose condensates. In analogy with quantum optics, where the control and engineering of quantum states can be maintained to a large extend, we consider the ...

Marsilio Ficino's Allegorical Reading of Optical Phenomena

open access: yesTeorie vědy, 2020
As a Platonist, Marsilio Ficino (1433–1499) was deeply interested in light  and its qualities. As a matter of fact, the metaphysics of light is so fundamental for him that it appears, treated more or less systematically, almost in all of his works.

Integrated optics for astronomical interferometry. I. Concept and astronomical applications

open access: yes, 1999
We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication.

Quantum optics with bosons and fermions [PDF]

open access: yes, 2008
Atom optics, a field which takes much inspiration from traditional optics, has advanced to the point that some of the fundamental experiments of quantum optics, involving photon correlations, have found atomic analogs.

Space‐Confined Growth of 2D InI Showing High Sensitivity in Photodetection

open access: yesAdvanced Electronic Materials, 2020
Layered InI has a great potential in optoelectronic applications due to its direct wide tunable bandgap. However, there is no single report about its 2D synthesis. Here, the growth of high‐quality and ultrathin InI flake (as thin as 8 nm) is reported via

Probing the conserved roles of cut in the development and function of optically different insect compound eyes

open access: yesFrontiers in Cell and Developmental Biology, 2023
Astonishing functional diversity exists among arthropod eyes, yet eye development relies on deeply conserved genes. This phenomenon is best understood for early events, whereas fewer investigations have focused on the influence of later transcriptional ...

The relationship between the Wigner-Weyl kinetic formalism and the complex geometrical optics method

open access: yes, 2005
The relationship between two different asymptotic techniques developed in order to describe the propagation of waves beyond the standard geometrical optics approximation, namely, the Wigner-Weyl kinetic formalism and the complex geometrical optics method,

Noncanonical quantum optics [PDF]

open access: yes, 2000
Modification of the right-hand-side of canonical commutation relations (CCR) naturally occurs if one considers a harmonic oscillator with indefinite frequency. Quantization of electromagnetic field by means of such a non-CCR algebra naturally removes the

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.
