Gauge federation as an alternative to unification
The standard model coupling constant physics
2014/12/19
We motivate and explore the possibility that extra SU(N) gauge groups may exist independently of the Standard Model groups, yet not be subgroups of some grand unified group. We study the running of th...
Alternative construction of the closed form of the Green's function for the wavized Maxwell fish-eye problem
Maxwell fish-eye problem Green function scalar wave optics gradient-index (GRIN) optics
2011/8/16
Abstract: In the recent paper [J.\ Phys.\ A 44 (2011) 065203], we have arrived at the closed-form expression for the Green's function for the partial differential operator describing propagation of a ...
Probing Student Understanding With Alternative Questioning Strategies
research methodology assessment electric circuits
2011/8/3
Abstract: Common research tasks ask students to identify a correct answer and justify their answer choice. We propose expanding the array of research tasks to access different knowledge that students ...
An alternative unified formulation for integer and fractional quantum Hall effects
quantum Hall effect fractional quantum effect degeneracy density Hall quantum number
2011/8/2
Abstract: In this paper, a new unified formulation of integer and fractional quantum Hall effect are presented. Firstly, under the condition of strong magnetic field and symmetry gauge, the Pauli equa...
Revisiting special relativity: A natural algebraic alternative to Minkowski spacetime
Special Relativity, Geometric algebra, Clifford algebra, Lorentz transformation,Minkowski
2011/9/2
Minkowski famously introduced the concept of a space-time continuum in 1908, merging three dimensional space with an imaginary time dimension represented by ict, a framework which naturally produced t...

A dark energy model alternative to generalized Chaplygin gas
energy model generalized Chaplygin gas
2010/12/27
We propose a new fluid model of dark energy for $-1 \leq \omega_{\text{eff}} \leq 0$ as an alternative to the generalized Chaplygin gas models. The energy density of dark energy fluid is severely supp...
Attempt-time Monte Carlo: an alternative for simulation of stochastic jump processes with time-dependent transition rates
Attempt-time Monte Carlo simulation of stochastic jump processes time-dependent transition rates
2010/11/24
cWe present a new method for simulating Markovian jump processes with time-dependent tran-
sitions rates, which avoids the transformation of random numbers by inverting time integrals over the rates....
An alternative to the conventional micro-canonical ensemble
alternative conventiona micro-canonical ensemble
2010/11/11
Usual approach to the foundations of quantum statistical physics is based on conventional micro-canonical ensemble as a starting point for deriving Boltzmann-Gibbs (BG) equilibrium. It leaves, howeve...
An alternative approach to exact wave functions for time-dependent coupled oscillator model of charged particle in variable magnetic field
time-dependent coupled oscillator model charged particle variable magnetic field
2010/11/4
A general treatment of the quantal time-dependent coupled oscillators in presence of the variable magnetic field is presented. The treatment is based on the use of an alternative canonical transforma...
An Alternative to Decoherence by Environment and the Appearance of a Classical World
Decoherence by Environment Appearance Classical World
2010/10/18
We provide an alternative approach to the decoherence-by-environment paradigm in the field of the quantum measurement process and the appearance of a classical world. In contrast to the decoherence ap...
Against a proposed alternative explanation of the Aharonov-Bohm effect
Against alternative explanation Aharonov-Bohm effect
2010/10/19
It has been suggested from time to time that the Aharonov-Bohm effect is somehow a consequence of a classical electromagnetic field phenomenon involving energy that is temporarily stored in the overla...
Towards Tests of Alternative Theories of Gravity with LISA
Gravitational Wave Astronomy Extreme-Mass-Ratio Inspirals
2010/3/18
The inspiral of stellar compact objects into massive black holes, usually known as extreme-mass-ratio inspirals (EMRIs), is one of the most important sources of gravitational-waves for the future Lase...
The Jebsen-Birkhoff theorem in alternative gravity
Jebsen-Birkhoff theorem alternative gravity
2010/3/17
We discuss the validity, or lack thereof, of the Jebsen-Birkhoff theorem in scalar-tensor theories by generalizing it and regarding the Brans-Dicke-like scalar as effective matter. Both the Jordan and...
