Nickelates are a material class that has excited scientists because of its recently discovered superconducting ability, and now a new study led by Cornell has changed where scientists thought this abi...
The origin of the phase in the interference of Bose-Einstein condensates
The condensation condensation wave function treatment the particles
2014/12/20
We consider the interference of two overlapping ideal Bose-Einstein condensates. The usual description of this phenomenon involves the introduction of a condensate wave function with a definite phase....
Logical Construction of the Ionization Energy Theory and the Origin of Physical Categories
Logical Construction the Ionization Energy Theory the Origin of Physical Categories General Physics
2012/5/31
Logical proofs and definitions are developed to establish (i) the energy-level spacings, \xi for each chemical element (from the periodic table of chemical elements) can be converted to the ionization...
Origin of optical second-harmonic generation in spherical gold nanoparticles: Local surface and nonlocal bulk contributions
Origin optical second-harmonic generation spherical gold nanoparticles Local surface nonlocal bulk contributions
2011/8/5
Abstract: The second-harmonic generation of 150 nm spherical gold nanoparticles is investigated both experimentally and theoretically. We demonstrate that the interference effects between dipolar and ...

Abstract: London presented a relation between suppercurrent density and magnetic vector potential [1], Pippard suggested a non-local relation [2], and the similar relation can be derived with the BCS ...
Origin And Evolution Of Energetic Particle Populations In The Magnetosphere
Constant current ions electrons magnetosphere ionosphere solar wind
2017/3/23
There is a constant flow of electrons ions and into and out of the magnetosphere and the intricacies of the magnetosphere determine the paths that these particles take through it. Although the plasma ...
Possible Origin of the Anomalous Far-infrared Absorption by Small Metal Particles
Origin of the Anomalous Far-infrared Absorption Small Metal Particles
2010/11/18
We have carried out far-infrared (far-IR) transmission measurements on the ligand stabilized
Au55 particles dispersed in CsI at volume fraction f = 0.002. We have found that while the
absorption coe...
Origin of the pseudogap and its influence on superconducting state
Origin of the pseudogap superconducting state
2010/11/23
When holes move in the background of strong antiferromagnetic correlation, two spatial scales
emerge which lead to a much reduced hopping integral with an additional phase factor. By taking
these tw...
A geometric solution to the coincidence problem, and the size of the landscape as the origin of hierarchy
geometric solution coincidence problem landscape
2010/12/21
Without assuming necessary conditions for observers such as galaxies or entropy production, we
show that the causal patch measure predicts the coincidence of vacuum energy and present matter
density...
Here the Origin of the pseudogap in HTSC is attributed to the modulated ntiferromagnetic (AFM) phase, whose preliminary version has been sketched recently by the present author [1]. Starting from the ...
We use molecular dynamics with a first-principles based shell model potential to study pyroelec-tricity in lithium niobate. We find that the primary pyroelectric effect is dominant, and pyroelec-trici...
On the Black Hole's Thermodynamics and the Entropic Origin of Gravity
Black Holes Entropy Gravity
2010/12/20
The Schwarzschild’s black hole dynamics in presence of gravity is described on using the thermodynamic equations of state for contractile materials. Its entropy and temperature, btained by using class...

Without assuming necessary conditions for observers such as galaxies or entropy production, we show that the causal patch measure predicts the coincidence of vacuum energy and present matter density. ...
A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
modal interpretation relational properties, measurement realism
2011/9/7
We study the process of observation (measurement), within the framework of a `perspectival' (`relational', `relative state')version of the modal interpretation of quantum mechanics. We show that if we...
A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
Quantum mechanics modal interpretations relational properties relativity Lorentz invariance
2011/9/7
Recent no go theorems by Dickson and Clifton (1998), Arntzenius (1998) and Myrvold (2002) demonstrate that current modal interpretations are incompatible with relativity. In this paper we propose stra...
