FERMI ACCELERATION
FERMI ACCELERATION particle
2015/9/29
Fermi acceleration is a mechanism, first suggested by
Enrico Fermi in 1949, to explain heating of particles in cosmic
rays.
Pole-Based Approximation of the Fermi-Dirac Function
Contour integral Fermi-Dirac function Rational approximation
2015/7/14
Two approaches for the efficient rational approximation of the Fermi-Dirac function are discussed: one uses the contour integral representation and conformal mapping, and the other is based on a versi...
There is a mass very huge star in Milky Way Galactic disk center, known as Milky Way "Nuclear-Star". Nuclear-Star mass exceeds solar mass 9 trillion times. Nuclear-Star center temperature exceed solar...
New evidence for zero-temperature relaxation in a spin-polarized Fermi liquid
The experiment report parameters and coefficients
2014/12/20
Spin-echo experiments are reported for 3He-4He solutions under extremely high B/T conditions, B=14.75 T and T≥1.73 mK. The 3He concentration x3 was adjusted close to the valu...
The Fermi–Hubbard model at unitarity
Simulated rare appeal screw Fermi gas the thermodynamic functions
2014/12/20
We simulate the dilute attractive Fermi–Hubbard model in the unitarity regime using a diagrammatic determinant Monte Carlo (MC) algorithm with worm-type updates. We obtain the dependence of the critic...
Giant viscosity enhancement in a spin-polarized fermi liquid
Fermi liquid viscosity mixture high magnetic field
2014/12/20
The viscosity is measured for a Fermi liquid, a dilute 3He-4He mixture, under extremely high magnetic field/temperature conditions (B≤14.8 T, T≥1.5 mK). The spin-splitting en...
Fermi-polaron problem: Diagrammatic Monte Carlo method for divergent sign-alternating series
Diagram to monte carlo method Fermi gas particle condensed matter
2014/12/20
We use the diagrammatic Monte Carlo approach to solve the problem of a single spin-down fermion resonantly interacting with a Fermi gas of spin-up particles. Our solution is important for understandin...
Fermi卫星于2008.6正式发射升空并取得了一系列令人瞩目的观测上的重大突破。2011.12我国的暗物质粒子探测卫星项目得以正式启动。为给暗物质粒子卫星将来的数据处理培养青年骨干，我们将于2013.1-2013.2在南京组织一个小规模的Fermi数据处理workshop（由于场地所限，学员仅限于对暗物质项目很感兴趣的博士生/博士后或低年级硕士生,总不超过10人；旁听不超过5人），对爆发性点源、...
Finding the ground state of a fermionic Hamiltonian using quantum Monte Carlo is a very difficult problem, due to the Fermi sign problem. While still scaling exponentially, full configuration-interact...
Pseudogap phenomenon in an ultracold Fermi gas with a p-wave pairing interaction
Pseudogap phenomenon in an ultracold Fermi gas with a p-wave pairing interaction
2012/2/27
We investigate single-particle properties of a one-component Fermi gas with a tunable p-wave interaction. Including pairing fluctuations associated with this anisotropic interaction within a $T$-matri...
Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium
Fermi-LAT Observations Diffuse Gamma-Ray Emission Implications Cosmic Rays the Interstellar Medium
2012/2/23
The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissio...
F-GAMMA: On the phenomenological classification of continuum radio spectra variability patterns of Fermi blazars
F-GAMMA phenomenological classification continuum radio spectra variability patterns Fermi blazars
2012/2/21
The F-GAMMA program is a coordinated effort to investigate the physics of Active Galactic Nuclei (AGNs) via multi-frequency monitoring of Fermi blazars. In the current study we show and discuss the ev...
Do Fermi-LAT observations really imply very large Lorentz factors in GRB outflows ?
gamma-ray burst: general gamma-ray burst: individual: GRB 080916C radiative transfer radiation mechanisms: non-thermal
2011/10/20
Recent detections of GeV photons in a few GRBs by Fermi-LAT imply huge bulk Lorentz factors to avoid a large gamma gamma optical depth at high energy. Estimates can be as high as Gamma ~ 1000 in the m...
