Implicit Q-learning-bootstrapped ant colony optimization for maritime moving-target observation scheduling with agile satellites

He Wang, Junyu Wu, Yeye Liu +5

Maritime moving-target observation scheduling with agile Earth observation satellites is a dynamic, sequence-dependent combinatorial optimization problem. Sea-surface targets move…

Charge dynamics in the Weyl semimetals NbIrTe $_{4}$ and TaIrTe $_{4}$ under pressure: Signatures of an electronic phase transition

M. Lamp, J. Ebad-Allah, A. Chmeruk +7

A high-pressure investigation of the Weyl semimetals NbIrTe $_{4}$ and TaIrTe $_{4}$ is presented, using infrared spectroscopy supplemented by density functional theory calculations. The…

Heterometallic spin-1/2 quantum magnet under hydrostatic pressure

M. J. Coak, D. Kamenskyi, S. P. M. Curley +14

We investigate the properties of CuVOF $_{4}$ (H $_{2}$ O) $_{6}$ $\cdot$ H $_{2}$ O, in which two different spin species, Cu(II) and V(IV), form antiferromagnetic spin-1/2 dimers with weak interdi…

Quasiparticle Fermi surfaces of niobium and niobium-titanium alloys at high pressure

D. Jones, A. Östlin, A. Chmeruk +4

The electronic structure of pure niobium and the niobium-titanium alloy Nb $_{0.44}$ Ti $_{0.56}$ in the bcc-phase at pressures up to $250$ GPa is investigated, to reveal possible fac…
