Following a "collapsing" wave function.
I study the quantum mechanics of a spin interacting with an “apparatus”. Although the evolution of the whole system is unitary, the spin evolution is not. The system is chosen so that the spin exhibits loss of quantum coherence, or “wavefunction collapse”, of the sort usually associated with a quantum measurement. The system is analyzed from the point of view of the spin density matrix (or “Sch...
متن کاملThe Wave Function of a Collapsing Star and Quantization Conditions
A very simple minisuperspace describing the Oppenheimer-Snyder collapsing star is found. The semiclassical wave function of that model turn out to describe a bound state. For fixed initial radius of the collapsing star, the corresponding Bohr-Sommerfeld quantization condition implies mass quantization. An extension of this model, and some consequences, are considered. This work is supported by ...
متن کاملExcitation of Chromospheric Wave Transients by Collapsing Granules
The excitation of acoustic waves is studied using 3D numerical simulations of the non-magnetic solar atmosphere and the upper convection zone. Transient acoustic waves in the atmosphere are excited at the top of the convective zone (the cooling layer) and immediately above in the convective overshoot zone, by small granules that undergo a rapid collapse, in the sense that upflow reverses to dow...
متن کاملCritical phenomena of collapsing massless scalar wave packets
An analytical model that represents the collapse of a massless scalar wave packet with continuous self-similarity is constructed, and critical phenomena are found. In the supercritical case, the mass of black holes is finite and has the form M ∝ (p− p∗)γ, with γ = 1/2.

متن کاملCollapsing focal segmental glomerulosclerosis following treatment with high-dose pamidronate.
Collapsing focal segmental glomerulosclerosis (FSGS) is a distinct clinicopathologic entity seen most commonly in young African American patients who present with renal insufficiency and nephrotic syndrome. The only epidemiologic factor previously linked to collapsing FSGS is HIV infection. Here clinicopathologic findings are reported for a distinctive population of seven patients, who were old...
