Special Issue Information

Dear Colleagues,

Shortcuts to adiabaticity are alternative fast processes which reproduce the same final state as the adiabatic process in a finite or even shorter time. In addition, shortcuts to adiabaticity are also fast routes to the final results of a system, where slow and adiabatic changes are produced by controlling the parameters of a system. In recent years, shortcuts to adiabaticity have been extended from Hermitian systems to non-Hermitian systems with non-Hermitian off-diagonal elements without parity–time (PT) symmetry. Because of their possible applications in quantum information processing and quantum control, shortcuts to adiabaticity with quantum open systems have attracted widespread attention. This Special Issue will attempt to cover the whole field of shortcuts to adiabaticity with quantum open systems in its widest sense, together with the related theory, experiments, and applications in various facets. We cordially and earnestly invite researchers to contribute their original and high-quality research papers which will inspire advances in theory, experiments, and their applications in shortcuts to adiabaticity with and without PT symmetry  systems. Potential topics include, but are not limited to:

  • Shortcuts to adiabaticity with quantum open systems;
  • Shortcuts to adiabaticity with and without PT symmetry;
  • Basic theory of shortcuts to adiabaticity;
  • Experimental realization of shortcuts to adiabaticity;
  • Physical application of shortcuts to adiabaticity;
  • Transitionless quantum driving;
  • “Fast-forward” scaling;
  • Inverse engineering based on Lewis–Riesenfeld in variants;
  • Rotating-wave approximation and non-rotating-wave approximation;
  • Shortcuts to adiabaticity in non-Hermitian systems;
  • Shortcuts to adiabaticity of pseudohermite system.

Superconductivity in highly pressurized hydrides has become the primary direction for the exploration of the fundamental upper limit of the superconducting transition temperature, Tc, after Drozdov et al. (Nature 2015, 525, 73) discovered a superconducting state with Tc=203 K in highly compressed sulfur hydride. To date, several dozen high-temperature superconducting polyhydrides have been discovered and, in addition, it was recently reported that highly compressed titanium and scandium exhibit record-high Tc (up to 36 K). This exceeded the Tc=9.2 K value of niobium many times over, which was the record-high  Tc ambient pressure metallic superconductor. Here, we analyzed the experimental data for the recently discovered high-pressure superconductors (which exhibit high transition temperatures within their classes): elemental titanium (Zhang et al., Nature Communications 2022; Liu et al., Phys. Rev. B 2022), TaH3 (He et al., Chinese Phys. Lett. 2023), LaBeH8 (Song et al., Phys. Rev. Lett. 2023), black phosphorous (Li et al., Proc. Natl. Acad. Sci. 2018; Jin et al., arXiv 2023), and violet (Wu et al., arXiv 2023) phosphorous to reveal the nonadiabaticity strength constant TθTF (where Tθ is the Debye temperature, and TF the Fermi temperature) in these superconductors. The analysis showed that the δ-phase of titanium and black phosphorous exhibits TθTF scores that are nearly identical to those associated with A15 superconductors, while the studied hydrides and violet phosphorous exhibit constants in the same ballpark as those of H3S and LaH10.
