Breaking Newton's Law
Breaking Newton's Law
2017/7/21
A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton’s equations of motion tell us that a moving body ke...
What can we see from Investment Simulation based on Generalized (m,2)-Zipf law?
eneralized Zipf law time series fluctuations investment
2015/8/5
The paper revisits the investment simulation based on strategies exhibited by Generalized (m,2)-Zipf law to present an interesting characterization of the wildness in financial time series. The invest...
Stresses and strains in the first law for Kaluza-Klein black holes
Both black hole kaluza-klein thermodynamics first law static black holes
2014/12/20
We consider how variations in the moduli of the compactification manifold contribute `pdV' type work terms to the first law for Kaluza-Klein black holes. We give a new proof for the S1 case, based on ...
The first law for boosted Kaluza-Klein black holes
Both black hole kaluza-klein thermodynamics time and space
2014/12/20
We study the thermodynamics of Kaluza-Klein black holes with momentum along the compact dimension, but vanishing angular momentum. These black holes are stationary, but non-rotating. We derive the fir...
Smarr formula and an extended first law for Lovelock gravity
Static properties lovelock gravitational black holes lovelock theory lovelock coupling
2014/12/18
We study properties of static, asymptotically AdS black holes in Lovelock gravity. Our main result is a Smarr formula that gives the mass in terms of geometrical quantities together with the parameter...

2012/6/29
Let $X_N$ be a $N\times N$ matrix whose entries are i.i.d. complex random variables with mean zero and variance $\frac{1}{N}$. We study the asymptotic spectral distribution of the eigenvalues of the c...
Comment on "Trouble with the Lorentz law of force: Incompatibility with special relativity and momentum conservation"
the Lorentz law of force Incompatibility special relativity momentum conservation Optics
2012/5/29
It has been recently argued [arXiv:1205.0096] that the Lorentz force is incompatible with Special Relativity and should be amended in the presence of magnetization and polarization in order to avoid a...
Does Lorentz Force Law Contradict the Principle and Theories of Relativity for Uniform Linear Motion?
Lorentz Force Law Principle and Theories of Relativity Uniform Linear Motion Classical Physics
2012/5/29
I show that no force or torque is generated in cases involving a charge and a magnet with their relative velocity zero, in any inertial frame of reference. A recent suspicion of an anomalous torque an...
Trouble with the Lorentz law of force: Incompatibility with special relativity and momentum conservation
the Lorentz law of force Incompatibility special relativity momentum conservation Optics
2012/5/17
The Lorentz law of force is the fifth pillar of classical electrodynamics, the other four being Maxwell's macroscopic equations. The Lorentz law is the universal expression of the force exerted by ele...

This work investigates the validity of the generalized second law of thermodynamics in modi?ed f(R) Horava-Lifshitz gravity proposed by Chaichian et al (2010) [Class. Quantum Grav. 27 (2010) 185021], ...
Disordered quantum wires: microscopic origins of the DMPK theory and Ohm's law
Disordered quantum wires microscopic origins the DMPK theory Ohm's law Mathematical Physics
2012/4/23
We study the electronic transport properties of the Anderson model on a strip, modeling a quasi one-dimensional disordered quantum wire. In the literature, the standard description of such wires is vi...
Hubble's law and faster than light expansion speeds
Hubble's law light expansion speeds four-velocity vector
2011/8/18
Abstract: Naively applying Hubble's law to a sufficiently distant object gives a receding velocity larger than the speed of light. By discussing a very similar situation in special relativity, we argu...
Mandelbrot Law of Evolving Networks
Mandelbrot Law Evolving Networks Degree distributions power-law exponent
2011/8/11
Abstract: Degree distributions of many real networks are known to follow the Mandelbrot law, which can be considered as an extension of the power law that determined by not only the power-law exponent...
Kramers' law: Validity, derivations and generalisations
Arrhenius’ law Kramers’ law metastability large deviations Wentzell Freidlin theory
2011/7/28
Abstract: Kramers' law describes the mean transition time of an overdamped Brownian particle between local minima in a potential landscape. We review different approaches that have been followed to ob...
In this letter, we study some evolution networks that grow with linear preferential attachment. Based upon some recent results on the quotient Gamma function, we give a rigorous proof of the asymptoti...
