Very accurate finite-nuclear-mass variational nonrelativistic calculations are performed for the lowest five
1D states (1s2 2p2, 1s2 2s1 3d1, 1s2 2s1 4d1, 1s2 2s1 5d1, and 1s2 2s1 6d1) of the beryllium atom (9Be). The
wave ...

We have performed very accurate quantum-mechanical calculations for the two lowest S states of the lithium
atom in order to determine the transition energy. In the nonrelativistic part of the calculations performed ...

In this work we report very accurate variational calculations of the complete pure vibrational spectrum of the D2 molecule performed within the framework where the Born-Oppenheimer (BO) approximation is not assumed. After ...

Two-dimensionalmagnetostatic cloaks, evenwhen perfectly designed tomitigate the magnetic field disturbance
of a scatterer, may be still detectable with Aharonov-Bohm (AB) measurements, and therefore may affect
quantum ...

A new algorithm for calculating the Hamiltonian matrix elements with all-electron explicitly correlated
Gaussian functions for quantum-mechanical calculations of atoms with two p electrons or a single d electron
have ...

Within the Lemaˆıtre-Tolman-Bondi formalism for gravitational collapse of inhomogeneous dust we analyze the parameter space that leads to the formation of a globally covered singularity (i.e. a black hole) when some ...

Variational calculations of ground and excited bound states on atomic and molecular systems
performed with basis functions that explicitly depend on the interparticle distances can generate
very accurate results provided ...

A (3+1)-dimensional asymptotically at Kerr black hole angular speed + can be used to de ne an e ective spring constant, k = m2 +. Its maximum value is the Schwarzschild
surface gravity, k = , which rapidly weakens as ...

An exact correspondence is shown between a new moving mirror trajectory in
(1+1)D and a spacetime in (1+1)D in which a black hole forms from the collapse of
a null shell. It is shown that the Bogolubov coe cients between ...

There is an exact correspondence between the simplest solution to Einstein's equa-
tions describing the formation of a black hole and a particular moving mirror tra-
jectory. In both cases the Bogolubov coe cients in 1+1 ...

In a previous paper, we studied the interior solution of a collapsing body in a non-local theory of gravity super-renormalizable at the quantum level. We found that the classical singularity is replaced by a bounce, after ...

In general relativity, gravitational collapse of matter fields ends with the formation
of a spacetime singularity, where the matter density becomes infinite and standard physics breaks down. According to the weak cosmic ...
