Comment on "Response calculations with an independent particle system with an exact one-particle density matrix''
calculations independent particle system one-particle density matrix
2010/11/16
We point out an error in the argument [PRL 105, 013002 (2010)] that the time independence of the occupation numbers in the adiabatic approximation follows from the invariance of the ground-state inter...
Linearly independent pure-state decomposition and quantum state discrimination
Linearly independent decomposition quantum discrimination
2010/11/8
We put the pure-state decomposition mathematical property of a mixed state to a physical test. We begin by characterizing all the possible decompositions of a rank-two mixed state by means of the comp...
Device-independent tests of classical and quantum dimensions
Device-independent tests classical quantum dimensions
2010/11/8
We address the problem of testing the dimensionality of classical and quantum systems in a `black-box' scenario. We develop a general formalism for tackling this problem. This allows us to derive lowe...
Cluster morphologies and model-independent Y_SZ estimates from Bolocam Sunyaev-Zel'dovich images
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present initial results from our ongoing program to image the Sunyaev-Zel'dovich (SZ) effect in galaxy clusters at 143 GHz using Bolocam; five clusters and one blank field are described in this man...
Spectroscopic Studies of Solar Corona VI: Trend in Line-width Variation of Coronal Emission Lines with Height Independent of the Structure of Coronal Loops
Sun corona coronal structures emission line widt techniques spectroscopy
2010/9/16
We have obtained spectroscopic observations in coronal emission lines by choosing two lines simultaneously, one [Fe x] 6374Å and the other [Fe xi] 7892Å or [Fe xiii] 10747Å or [Fe xi...
Current fluctuations for independent random walks in multiple dimensions
Independent random walks hydrodynamic limit current Independent random walks
2010/12/6
Consider a system of particles evolving as independent and iden-tically distributed (i.i.d.) random walks. Initial fluctuations in the particle density get translated over time with velocity ~v, the c...
Device-Independent Quantum Key Distribution with Commuting Measurements
Device-Independent Quantum Key Distribution ommuting Measurements
2010/10/19
We consider quantum key distribution in the device-independent scenario, i.e., where the
legitimate parties do not know (or trust) the exact specification of their apparatus. We show
how secure key ...
Independent Attacks in Imperfect Settings; A Case for A Two Way Quantum Key Distribution Scheme
Independent Attacks Imperfect Settings A Case Quantum Key Distribution Scheme
2010/10/20
We review the study on a two way quantum key distribution protocol given imperfect settings
through a simple analysis of a toy model and show that it can outperform a BB84 setup. We provide the suffi...

Characterizations of processes stationary independent increments
2010/11/26
Our purpose is to investigate properties for processes with stationary and independent increments under G-expectation. As applications,we prove the martingale characterization to G-Brownian motion and...

Secure device-independent quantum key distribution causally independent measurement devices
2010/10/19
Device-independent quantum key distribution aims to provide key distribution schemes whose security is based on the laws of quantum physics but which does not require any assumptions

Counting SO(9)xSU(2) representations in coordinate independent state space of SU(2) Matrix Theory
Counting SO(9)xSU(2) representations SU(2) Matrix Theory
2010/12/8
We consider decomposition of coordinate independent states into SO(9)×SU(2)representations in SU(2) Matrix theory. To see what and how many representations appear in the decomposition, we compute the ...

Time independent seismic hazard analysis Greece Bayesian statistics
2009/12/11
A Bayesian statistics approach is applied in the seismogenic sources of Greece and the surrounding area in order to assess seismic hazard, assuming that the earthquake occurrence follows the Poisson p...
A consistent molecular hydrogen isotope chemistry scheme based on an independent bond approximation

2009/11/19
The isotopic composition of molecular hydrogen (H2) produced by photochemical oxidation of methane (CH4) and Volatile Organic Compounds (VOCs) is a key quantity in the global isotope budget of (H2). T...

2009/11/11
We apply Independent Component Analysis (ICA) to seismic signals recorded at Stromboli volcano. Firstly, we show how ICA works considering synthetic signals, which are generated by dynamical systems. ...
