Spotting the spin of the Majorana fermion under the microscope（图）
the spin Majorana fermion microscope
2017/10/26
Researchers at Princeton University have detected a unique quantum property of an elusive particle notable for behaving simultaneously like matter and antimatter. The particle, known as the Majorana f...
Fermions are the building blocks of matter, interacting in a multitude of permutations to give rise to the elements of the periodic table. Without fermions, the physical world would not exist.Examples...
Quantum statistics: Is there an effective fermion repulsion or boson attraction?
Fermions and bosons highly misleading quantum statistics
2014/12/20
Physicists often claim that there is an effective repulsion between fermions, implied by the Pauli principle, and a corresponding effective attraction between bosons. We examine the origins and validi...
Heavy-Fermion Instability in Double-Degenerate Plasmas
Heavy-Fermion Instability Double-Degenerate Plasmas Plasma Physics
2012/5/28
In this work we study the propagations of normal frequency modes for quantum hydrodynamic (QHD) waves in the linear limit and introduce a new kind of instability in a double-degenerate plasma. Three d...
Numerical Solution of the Time-Dependent Dirac Equation in Coordinate Space without Fermion-Doubling
Dirac equation Numerical method Fermion doubling problem Klein paradox Relativistic wave packet
2011/8/11
Abstract: The application of a recently developed numerical method for the solution of the time-dependent Dirac equation is presented. This numerical method, described in \cite{Lorin2011190}, is based...
On kinematical constraints in fermion-antifermion systems
kinematical constraints fermion-antifermion systems
2011/7/21
We consider the scattering of fermions off antifermions with spin 1/2 and 3/2. Starting from helicity partial-wave scattering amplitudes we derive transformations that eliminate all kinematical constr...
Two-fermion composite quasi-bosons and deformed oscillators
Two-fermion composite quasi-bosons deformed oscillators Quantum Physics
2011/10/9
Abstract: The concept of quasi-bosons or composite bosons (like mesons, excitons etc.) has a wide range of potential physical applications. Even composed of two pure fermions, the quasi-boson creation...
Boost modes for a massive fermion field
boost symmetry fermion field Wightman function zero mode
2011/9/29
Abstract: We have shown that Wightman function of a free quantum field generates any complete set of solutions of relativistic wave equations. Using this approach we have constructed the complete set ...
The Standard Model in the Isotopic Foldy-Wouthuysen Representation without Higgs Bosons in the Fermion Sector. Spontaneous Breaking of Parity and "Dark Matter" Problems
The Standard Model Isotopic Foldy-Wouthuysen Higgs Boson
2011/8/2
Abstract: The Standard Model with massive fermions is formulated in the isotopic Foldy-Wouthuysen representation. SU(2)xU(1) - invariance of the theory in this representation is independent of whether...

2011/3/2
The analytical algorithm previously proposed by the author for matching the Volkov-Akulov (VA) and Komargodski-Seiberg (KS) actions describing the Nambu-Goldstone (NG) fermion, is discussed.

2011/3/2
We first give an overview of the shell-correction method which was developed by V. M.Strutinsky as a practicable and efficient approximation to the general selfconsistent theory of finite fermion syst...

We analyze the ground state of a strongly interacting fermion chain with a supersymmetry. We conjecture a number of exact results, such as a hidden duality between weak and strong couplings. By explo...

2010/12/24
In a recent paper published in this journal, Bazeia and collaborators [Phys. Lett. B 671, (2009) 402] analyze braneworld models with nonstandard dynamics. It was found that the generalized braneworld...
