Electrical detection and modulation of magnetism in a Dy-based ferroelectric single-molecule magnet
Nature Communications, 2023 Electrical control of magnetism in single-molecule magnets with peculiar quantum magnetic behaviours has promise for applications in molecular electronics and quantum computing. Nevertheless, such kind of magnetoelectric effects have not been achieved in

American Journal of Physics, 2004 A simple model of a quantum clock is applied to the old and controversial problem of how long a particle takes to tunnel through a quantum barrier. The model has the advantage of yielding sensible results for energy eigenstates and does not require the use of time-dependent wave packets.

Tunnelling series in terms of perturbation theory for quantum spin systems [PDF]
, 1999 Considered is quantum tunnelling in anisotropic spin systems in a magnetic field perpendicular to the anisotropy axis. In the domain of small field the problem of calculating tunnelling splitting of energy levels is reduced to constructing the ...

Computational multiqubit tunnelling in programmable quantum annealers
Nature Communications, 2016 Quantum tunnelling may be advantageous for quantum annealing, but multiqubit tunnelling has not yet been observed or characterized theoretically.

Tunneling decay of false domain walls: the silence of the lambs [PDF]
, 2015 We study the decay of "false” domain walls, which are metastable states of the quantum theory where the true vacuum is trapped inside the wall, with the false vacuum outside.

Site-specific electrical contacts with the two-dimensional materials
Nature Communications, 2020 Here, the authors use in situ transmission electron microscopy to measure the interface properties of electrical contacts with MoS2, ReS2, and graphene, and find that direct quantum tunnelling across van-der-Waals-bonded interfaces is more favourable ...

Manipulating tunnelling gateways in condensed phase isomerization
Natural Sciences, 2023 When a chemical reaction occurs via tunnelling, a simple mass‐dependence is expected, where substitution of atoms by heavier isotopes leads to a reduced reaction rate.

Simulation of direct source-to-drain tunnelling using the density gradient formalism: Non-Equilibrium Greens Function calibration [PDF]
, 2002 Quantum mechanical confinement effects, gate, hand-to-hand and source-to-drain tunnelling will dramatically affect the characteristics of future generation nanometre scaled devices.
