Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Is Quantum Chaos Weaker Than Classical Chaos?
, 2003 We investigate chaotic behavior in a 2-D Hamiltonian system - oscillators with anharmonic coupling. We compare the classical system with quantum system.

Advanced Engineering Materials, EarlyView.An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

The solution of the quantum $A_1$ T-system for arbitrary boundary
, 2011 We solve the quantum version of the $A_1$ $T$-system by use of quantum networks. The system is interpreted as a particular set of mutations of a suitable (infinite-rank) quantum cluster algebra, and Laurent positivity follows from our solution.

Extremely quick thermalization in a macroscopic quantum system for a typical nonequilibrium subspace [PDF]
, 2014 The fact that macroscopic systems approach thermal equilibrium may seem puzzling, for example, because it may seem to conflict with the time-reversibility of the microscopic dynamics.

Hardware-efficient variational quantum eigensolver for small molecules and quantum magnets [PDF]
Nature, 2017 Quantum computers can be used to address electronic-structure problems and problems in materials science and condensed matter physics that can be formulated as interacting fermionic problems, problems which stretch the limits of existing high-performance

Quantum Analysis of Teleportation Quality Degradation Induced by Loss and Multiple-Photon Generation
IEEE AccessIn (Brewster et al., 2021), we considered the entanglement degradation due to multiple-photon-pair generation as measured by a Clauser-Horne-Shimony-Holt (CHSH) experiment.
