In this paper we investigate the critical collapse of an ultrarelativistic perfect fluid with the equation of state $P=(\Gamma-1)\rho$ in the limit of $\Gamma\to 1$. We calculate the limiting continuously self similar (CSS) solution and the limiting

It is commonly believed that variance-optimized wave functions yield “satisfactory” if not, in principle, better estimates of non-energy-related physical properties than their energy-optimized counterparts. We test this notion by calculating a nu

Wave functions are optimized using a histogram-based technique that deals with the statistical error plaguing traditional Monte Carlo optimizations. Following a sensitivity study on H2+, we variance- and energy-optimize explicitly correlated wave fun

Application specific aberration as a result of localized heating of lens elements during exposure has become more significant in recent years due to increasing low k1 applications. Modern scanners are equipped with sophisticated lens manipulators tha

As the industry drives to lower k1 imaging we commonly accept the use of higher NA imaging and advanced illumination conditions. The advent of this technology shift has given rise to very exotic pupil spread functions that have some areas of high the

This work is an extension of Langfelder, Rothstein, and Vrbik’s [J. Chem. Phys. 107, 8525 (1997), (LRV)] algorithm that samples the “exact” ground state distribution φ02. The distribution is the same as that obtained from exactly solving the S

Kar and Mandal [Phys. Lett. A 240 (1998) 301] reported a remarkably accurate, three non-linear parameter correlated wavefunction for a variety of two-electron systems. Unfortunately, due to linear dependences in the trial function, the secular equati

We study the interaction of an n-dimensional topological defect (n-brane) described by the Nambu-Goto action with a higher-dimensional Schwarzschild black hole moving in the bulk spacetime. We derive the general form of the perturbation equations for

The capture of a straight, infinitely long cosmic string by a rotating black hole with rotation parameter $a$ is considered. We assume that a string is moving with velocity $v$ and that initially the string is parallel to the axis of rotation of the
