X-ray flares following short gamma-ray bursts from shock heating of binary stellar companions
Andrew I. MacFadyen, Enrico Ramirez-Ruiz, Weiqun Zhang
The discovery of long-lasting (~100 s) X-ray flares following short gamma-ray bursts initially called into question whether they were truly classical short-hard bursts. Opinion ove…
Primordial binaries and intermediate mass black holes in globular clusters
M. Trenti, E. Ardi, S. Mineshige +1
We present the first study of the dynamical evolution of a star cluster that combines a significant population of primordial binaries with the presence of a central black hole. We…
Dephasing representation of quantum fidelity for general pure and mixed states
Jiri Vanicek
General semiclassical expression for quantum fidelity (Loschmidt echo) of arbitrary pure and mixed states is derived. It expresses fidelity as an interference sum of dephasing traj…
The redshift distribution of gamma-ray bursts revisited
Priyamvada Natarajan, Badr Albanna, Jens Hjorth +3
In this letter, we calculate the redshift distribution of gamma-ray bursts assuming that they trace (i) the globally averaged star formation rate or (ii) the average metallicity in…
Modulational instability for nonlinear Schrodinger equations with a periodic potential
Jared C. Bronski, Zoi Rapti
We study the stability properties of periodic solutions to the Nonlinear Schrödinger (NLS) equation with a periodic potential. We exploit the symmetries of the problem, in particul…
On the preservation of absolutely continuous spectrum for Schrodinger operators
Sergey A. Denisov
We present general principles for the preservation of a.c. spectrum under weak perturbations. The Schrodinger operators on the strip and on the Caley tree (Bethe lattice) are consi…
