Laser scaling for generation of megatesla magnetic fields by microtube implosions

Abstract

Microtube implosions are a novel scheme to generate ultrahigh magnetic fields on the megatesla order. These implosions are driven by ultraintense and ultrashort laser pulses. Using two-and three-dimensional particle simulations where megatesla-order magnetic fields can be achieved, we demonstrate scaling and criteria in terms of laser parameters such as laser intensity and laser energy to facilitate practical experiments toward the realization of extreme physical conditions, which have yet to be realized in laboratories. Microtube implosions should provide a new platform for studies in fundamental and applied physics relevant to ultrahigh magnetic fields.

Energy eigenvalues and finite-temperature magnetization for the improved Scarf II potential in the presence of external magnetic and Aharonov-Bohm flux fields

“…For this purpose, a laser pulse implosion device (LPID) could be employed. The LPID is known to produce very strong magnetic fields of the order of thousands megatesla [ 60 ]. If the external fields are both turned on ( B ≠ 0, Φ AB ≠ 0), the energy eigenvalues of the molecules are summarized in Table 4 , Table 5 .…”

Energy spectrum and zero-temperature magnetic functions of a position-dependent mass system in a Pöschl-Teller-type potential constrained by a vector magnetic potential field

“…However, a weak magnetic field only partially removes degeneracy from the energy levels in the molecules. With the aid of microtube implosion devices [63], much stronger magnetic fields sufficient to eliminate degeneracy from the energy levels of the molecules could be generated. The difference in the magnetic and AB field intensities required to eliminate degeneracy from the energy states of the molecules could arise from the different vector potentials representing the magnetic field and AB field.…”

Observation of proton modulations in laser–solid interaction

“…The generation of strong magnetic fields from laser-plasma interaction has been predicted [25][26][27] and such strong magnetic fields or their ramifications are observed with underdense targets [28,29], as well as overdense targets like a metal foil [30][31][32][33] of thicknesses ⩾100 µm. Recently, a new concept called microtube implosion has been proposed, which predicts a magnetic field of the order of MT from the interaction of intense laser pulses with a structured target [34,35].…”
