F. O. Prado, N. G. de Almeida, M. H. Y. Moussa and C. J. Villas-Bôas Universidade Federal de São Carlos, São Carlos, Brazil and Universidade Católica de Goiás, Goiânia, Brazil Abstract In this work we show how to engineer bilinear and quadratic Hamiltonians in cavity quantum electrodynamics (QED) through the interaction of a single driven two-level atom with cavity modes. The validity of the en...

Materials and Methods: The study was conducted on 30 children in the age group of 8-15yrs, each having at least three permanent molar teeth with non-pulpally involved carious lesions. Each of the three teeth was randomly assigned to be treated with either Carie-care, Carisolv or high-speed cavity excavation with air-rotor. The following assessments were made for each tooth: efficacy of caries r...

We report nonclassical correlations in the light transmitted by a collection of two-level atoms strongly coupled to a single mode of the electromagnetic field of a driven optical cavity. This cavity QED system can produce bunched light that violates the Schwarz inequality due to the state preparation of the system from the detection of a photon. The correlation function shows oscillations at a ...

We propose a realistic protocol for the preparation and readout of mechanical Bell states in an optomechanical system. The proposal relies on parameters characterizing a photonic crystal cavity mode, coupled to two localized flexural modes of the structure, but equally applies to other optomechanical systems in the same parameter range. The nonclassical states are heralded via optical postselec...

Cornell is testing superconducting cavities for many different purposes: system development for CESR, supporting technology transfer of CESR SRF systems to storage ring light sources around the world, collaboration with the world-wide TESLA project, collaboration with Muon Collider/Neutrino Factory projects, developing an Energy Recovery Linac (ERL) based synchrotron light source in collaborati...

OBJECTIVES This study aimed to investigate the effect of clinical clerkship-associated achievements, such as performance of procedures at the student clinic, observation, and attitude towards a clerkship, on the objective structured clinical examination (OSCE) scores of dental students graduating in restorative dentistry. MATERIALS AND METHODS The OSCEs consisted of two stations designed to a...

The aim of this study was to evaluate in vitro the effect of sputter-coating for SEM analysis on the formation of cracks on root-end surfaces after retrograde cavity preparation with ultrasonic tips. Root-end cavities were prepared with either Satelec S12/90 degrees D diamond-coated or S12/90 degrees non-coated stainless steel retrotips. Impressions were taken before and after retrograde cavity...

The cooling channel of the CERN reference scenario [1] for a possible neutrino factory [2] requires an approximately 200 m long lattice, which provides solenoidal magnetic fields plus longitudinal electric fields at the same time. The electric real estate field gradient along the structure shall be 2 MV/m at 44 MHz, or 4 MV/m at 88 MHz, respectively. The CERN approach incorporates the solenoids...

We show how to use the radiation pressure optomechanical coupling between a mechanical oscillator and an optical cavity field to generate in a heralded way a single quantum of mechanical motion (a Fock state). Starting with the oscillator close to its ground state, a laser pumping the upper motional sideband produces correlated photon-phonon pairs via optomechanical parametric down-conversion. ...

This article presents a novel virtual teeth drilling system designed to aid dentists, dental students, and researchers in getting acquainted with teeth anatomy, the handling of drilling instruments, and the challenges associated with drilling procedures during endodontic therapy. The system is designed to be used for educational and research purposes in dental schools. The application features ...
