Radon and thoron daughter activities in the environment of the King George Island (West Antarctica)
Antarctica radon uranium thorium spectrometry
2015/9/10
Results of 253 gamma spectrometric analyses of radon daughters in soil and bedrocks of the King George Island
(West Antarctica) are presented. Measured values range from 0.1 to 58.4 Bq/kg, and from 4...
Sensitivity Analysis of Spectral Indices to Ozone Absorption Using Physical Simulations in a Forest Environment: Comparative Study between MODIS, SPOT VéGéTATION & AVHRR
Spectral Indices Ozone Absorption Using Physical Simulations
2015/7/29
Considering a forest cover (Balsam Fir with various densities) we analyze the sensitivity of several vegetation indices to
ozone absorption using physical simulations in the spectral bands of MODIS,...
Effective Hamiltonian in the Problem of a "Central Spin" Coupled to a Spin Environment
Spin quantum interactive microcosmic spin micro rotation magnetic particles low-energy properties model
2014/12/23
We consider here the problem of a "giant spin", with spin quantum number S≫1, interacting with a set of microscopic spins. Interactions between the microscopic spins are ignored. This model desc...

Nuclear and Non-Ionizing Energy-Loss for Coulomb Scattered Particles from Low Energy up to Relativistic Regime in Space Radiation Environment
Coulomb Scattered Particles Low Energy Relativistic Regime Space Radiation Environment
2011/1/5
In the space environment, instruments onboard of spacecrafts can be affected by displacement damage due to radiation. The differential scattering cross section for screened nucleus–nucleus interaction...
Demonstration of mode splitting in an optical microcavity in aqueous environment
optical microcavity aqueous environment
2010/11/16
Scatterer induced modal coupling and the consequent mode splitting in a whispering gallery mode resonator is demonstrated in aqueous environment. The rate of change in splitting as particles enter th...
The behavior of many quantum systems strongly depends on their interaction with the
environment. The dissipative processes induced by interaction with the environment have
a broad area of applicatio...
Three qubits in a symmetric environment: dissipatively generated asymptotic entanglement
Three qubits symmetric environment asymptotic entanglement
2010/10/18
We study the asymptotic entanglement of three identical qubits under the action of a Markovian open system dynamics that does not distinguish them.We show that by adding a completely depolarized qubit...
An Alternative to Decoherence by Environment and the Appearance of a Classical World
Decoherence by Environment Appearance Classical World
2010/10/18
We provide an alternative approach to the decoherence-by-environment paradigm in the field of the quantum measurement process and the appearance of a classical world. In contrast to the decoherence ap...
Environment Assisted Precision Measurement
Precision Measurement trapped ions clock sensitivity
2010/3/10
We describe a method to enhance the sensitivity of precision measurements that takes advantage of a quantum sensor's environment to amplify its response to weak external perturbations. An individual q...
Bright and Dark periods in the Entanglement Dynamics of Interacting Qubits in Contact with the Environment
Bright and Dark periods Entanglement Dynamics Interacting Qubits Environment
2010/4/8
Interaction among the qubits are basis to many quantum logic operations. We report how such inter-qubit interactions can lead to new features, in the form of bright and dark periods in the entanglemen...
q-entropies and the entanglement dynamics of two-qubits interacting with an environment
q-Entropies Entanglement dynamics
2010/7/5
We investigate entropic aspects of the quantum entanglement dynamics of two-qubits systems interacting with an environment. In particular we consider the detection, based on the violation of classical...
We consider non-interacting multi-qubit systems as controllable probes of an environment of defects/impurities modelled as a composite spin-boson environment. The spin-boson environment consists of a ...
