Single-hole spectral function and spin-charge separation in the t-J model
Worm hole green's function monte carlo simulation spectral analysis spectral function thermodynamics
2014/12/22
Worm algorithm Monte Carlo simulations of the hole Green function with subsequent spectral analysis were performed for 0.1<~J/t<~0.4 on lattices with up to L×L=32×32 sites at a temperature as low as T...
Scale-Separation Scheme for Simulating Superfluid Turbulence: Kelvin-Wave Cascade
Kelvin from the distorted wave of vortex superfluid turbulence low temperature the numerical simulation of vortex line
2014/12/20
A Kolmogorov-type cascade of Kelvin waves—the distortion waves on vortex lines—plays a key part in the relaxation of superfluid turbulence at low temperatures. We propose an efficient numeric scheme f...

The Bohr radius is a space-like separation between the proton and electron in the hydrogen atom. According to the Copenhagen school of quantum mechanics, the proton is sitting in the absolute Lorentz ...
Quantum Incompressibility of a Freely Falling Hydrogen Atom in a Circular Rydberg State, and a Gravitationally-Induced Charge Separation Effect in Superconducting Systems
Quantum Incompressibility Gravitationally-Induced Charge Separation Effect Superconducting Systems
2010/11/8
Freely falling point-like objects converge toward the center of the Earth. Hence the gravitational field of the Earth is inhomogeneous, and possesses a tidal component. The free fall of an extended qu...
A Quasi-separation Principle and Newton-like Scheme for Coherent Quantum LQG Control
Quasi-separation Principle Newton-like Scheme Coherent Quantum LQG Control
