Strongly anharmonic flux-tunable transmon based on InAs-Al 2D heterostructure [PDF]
Nature CommunicationsThe gatemon qubits, made of transparent superconducting-semiconducting Josephson junctions, typically have even weaker anharmonicity than the opaque AlOx-junction transmons.

Metallic Bond Induces Soft Phonon Mode and Anharmonicity in Heusler Alloy [PDF]
Advanced ScienceThe fruitful functional performances of metastable Heusler alloys originate from the martensitic transformation driven by the transverse acoustic soft phonon mode, regulated by anharmonicity. However, the origins of the soft mode and the anharmonicity in

The Anharmonic Electron-Phonon Problem [PDF]
Physical Review Letters, 1996 The anharmonic electron-phonon problem is solved in the infinite-dimensional limit using quantum Monte Carlo simulation. Charge-density-wave order is seen to remain at half filling even though the anharmonicity removes the particle-hole symmetry (and hence the nesting instability) of the model.

Anharmonic effect on the thermally activated migration of {101̄2} twin interfaces in magnesium [PDF]
Materials Research Letters, 2021 Using a recent linear scaling method that fully accounts for anharmonic thermal vibrations, we calculated the activation free energy for $ \{10\bar {1}2\} $ twin boundary migration in magnesium up to 450 K, under both resolved shear stresses and non ...

Theory of Non-Equilibrium Heat Transport in Anharmonic Multiprobe Systems at High Temperatures
Entropy, 2021 We consider the problem of heat transport by vibrational modes between Langevin thermostats connected by a central device. The latter is anharmonic and can be subject to large temperature difference and thus be out of equilibrium.

Inorganics, 2021 The anharmonic phonon behavior in zirconium hydrides and deuterides, including ϵ-ZrH2, γ-ZrH, and γ-ZrD, has been investigated from aspects of inelastic neutron scattering (INS) and lattice dynamics calculations within the framework of density functional

Tuning the Nonlinear Optical Properties of Quantum Dot by Noise-Anharmonicity Interaction
Atoms, 2022 Current inspection rigorously explores the tuning of a few relevant nonlinear optical (NLO)properties of GaAs quantum dot (QD) under the stewardship of Gaussian noise-anharmonicity interplay.

Raman Spectroscopic Study of Ruddlesden—Popper Tetragonal Sr2VO4
Crystals, 2023 The lattice dynamics of tetragonal Sr2VO4 with a Ruddlesden—Popper-layered crystal structure was studied via Raman spectroscopy. We observed three of the four expected Raman-active modes under ambient conditions.
