Non-Markovian qubit dynamics in a thermal field bath: Relaxation, decoherence and entanglement
S. Shresta, C. Anastopoulos, A. Dragulescu +1
We study the non-Markovian dynamics of a qubit made up of a two-level atom interacting with an electromagnetic field (EMF) initially at finite temperature. Unlike most earlier stud…
Applications of physics to economics and finance: Money, income, wealth, and the stock market
Adrian A. Dragulescu
Several problems arising in Economics and Finance are analyzed using concepts and quantitative methods from Physics. Here is the abridged abstact: Chapter 1: By analogy with energy…
Statistical Mechanics of Money, Income, and Wealth: A Short Survey
Adrian A. Dragulescu, Victor M. Yakovenko
In this short paper, we overview and extend the results of our papers cond-mat/0001432, cond-mat/0008305, and cond-mat/0103544, where we use an analogy with statistical physics to…
Probability distribution of returns in the Heston model with stochastic volatility
Adrian A. Dragulescu, Victor M. Yakovenko
We study the Heston model, where the stock price dynamics is governed by a geometrical (multiplicative) Brownian motion with stochastic variance. We solve the corresponding Fokker-…
Exponential and power-law probability distributions of wealth and income in the United Kingdom and the United States
Adrian Dragulescu, Victor M. Yakovenko
We present the data on wealth and income distributions in the United Kingdom, as well as on the income distributions in the individual states of the USA. In all of these data, we f…
Evidence for the exponential distribution of income in the USA
Adrian Dragulescu, Victor M. Yakovenko
Using tax and census data, we demonstrate that the distribution of individual income in the USA is exponential. Our calculated Lorenz curve without fitting parameters and Gini coef…
