In quantum information theory, the error exponents characterize the best rate of exponential convergence of the error towards 0 or 1, as the number of copies of the underlying resources increases. In ...
Study of tunable resonances in laser beam divergence and beam deflection
Tunable radiofrequency resonances noise of lasers beam-width fluctuation beam-deviation fluctuation
2012/5/29
New, fundamental resonant properties of laser resonators are theoretically predicted and experimentally demonstrated. These resonances occur either in the time dependence of the beam width and that of...
On the divergence of time-dependent perturbation theory applied to laser-induced molecular transitions: Analytical calculations (1)
time-dependent perturbation theory laser-induced molecular transitions Analytical calculations Mathematical Physics
2012/4/18
Shaped laser pulses are a powerful tool to induce population transfer between electronic molecular states, and time-dependent perturbation theory is suitable for a description of such a transfer in we...
Black hole entropy divergence and the uncertainty principle
Black hole entropy divergence uncertainty principle
2010/11/11
Black hole entropy has been shown by 't Hooft to diverge at the horizon. The region near the horizon is in a thermal state, so entropy is linear to energy which consequently also diverges. We find a s...
