Lasetron: a proposed source of powerful nuclear-time-scale electromagnetic bursts.
نویسندگان
چکیده
Electromagnetic bursts of substantial energy on a nuclear time scale of 10(-21)-10(-22) s [zeptosecond (zs) to sub-zs] can theoretically be generated by a perawatt or multiterawatt laser beam focused on a subwavelength-size solid particle or thin wire. Terawatt laser in a similar setup could be instrumental in reaching the subattosecond domain. The system may also generate a half-cycle pulse magnetic field on astrophysical scale up to approximately 10(6) T.

Γ-ray Bursts and Neutron Star Mergers - Possibly the Strongest Explosions in the Universe
γ-ray bursts have baffled theorists ever since their accidental discovery at the sixties. We suggest that these bursts originate in merger of neutron star binaries, taking place at cosmological distances. These mergers release ≈ 10ergs, in what are possibly the strongest explosions in the Universe. If even a small fraction of this energy is channeled to an electromagnetic signal it will be dete...
متن کاملComment on Lasetron
In a recent paper [1] Kaplan and Shkolnikov propose to generate intense ultrashort pulses of electromagnetic radiation in the range ∼ 10−21 s (zeptosecond) and large magnetic fields by using a petawatt electron laser irradiating a small solid particle or a piece of wire of a submicron size. In this comment we would like to point out that the method proposed in Ref. [1] will not achieve the desi...
متن کاملHot Neutron Stars as a Source for Gamma Ray Bursts at Cosmological Distance Scales
We discuss the possibility that the sources for gamma ray bursts are hot neutron stars at cosmological distance scales. The temperature of such stars would be T ∼ 1MeV. Such hot stars can produce an electromagnetic blast wave provided that the ratio of baryon and photon numbers NB/Nγ ≤ 10. The typical time scale for such blasts, the total luminosity, and correlation of gamma ray energy with tim...
متن کاملIntergalactic Propagation of Uhe Cosmic Rays
We discuss the intergalactic propagation of ultra-high-energy cosmic rays (UHECRs) with energies E > ∼ 10 eV. We consider the propagation of UHECRs under the influence of the energy-dependent deflection by a weak random magnetic field in the intergalactic medium and energy losses by photo-pion and pair production. We calculate arrival spectra taking full account of the kinematics of photo-pion ...
متن کاملSystematic variation in the apparent burning area of thermonuclear bursts and its implication for neutron star radius measurement
Precision measurements of neutron star radii can provide a powerful probe of the properties of cold matter beyond nuclear density. Beginning in the late 1970s it was proposed that the radius could be obtained from the apparent or inferred emitting area during the decay portions of thermonuclear (type I) X-ray bursts. However, this apparent area is generally not constant, preventing reliable mea...
