Halide Perovskite: A Rich Source of Thermal Insulator

Advanced Science, EarlyView.
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Revision of the Structure of Acremine P from a Marine-Derived Strain of Acremonium persicinum

Molecules, 2017
The previously published structure of the fungal metabolite acremine P is revised by re-evaluation of chemical shift values and NOESY data, and by DFT calculations.

Dipolar Coupling Errors in Nuclear Spin Qubits

Advanced Science, EarlyView.
Multi‐nuclear spin registers of phosphorus‐atom qubits in silicon have demonstrated 99.99% single and >$>$99.9% two qubit gate fidelities. Despite nanometer separation, read‐out fidelities between individual nuclear spins within the register are not identical.

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

Advanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Stochastic wavefunction diagrams for electromagnetically induced transparency, inversionless gain and shelving

, 1998
A rigorous diagrammatic description of stochastic wavefunction evolution for electromagnetically induced transparency (EIT) and inversionless gain in coherently driven three-level systems is developed and applied to transient and steady-state conditions.

Comparison between tensor methods and neural networks in electronic structure calculations*** [PDF]

ESAIM: Proceedings and Surveys
This article compares the tensor method density matrix renormalization group (DMRG) with two neural network based methods -namely FermiNet and PauliNet) for determining the ground state wavefunction of the many-body electronic Schrödinger problem.

Role of Flux Density (Wavefunction Gradient Wavefunction) in Quantum Bound States

, 2019
In the literature (1) it has been noted that (d/dx W)/W - (d/dx W*)/W* represents a classical velocity, where W is the wavefunction. For bound states, this expression is zero, yet (d/dxW)/W seems to play the role of density flux as d/dx (WW) = 2W d/dxW ...

High‐Pressure Modulation of Breathing Kagome Lattice: Cascade of Lifshitz Transitions and Evolution of the Electronic Structure

Advanced Science, EarlyView.
External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...

Two-dimensional specialisation of the quaternion wavefunction framework: Circulation as phase period and the Kutta condition as wavefunction regularity in airfoil aerodynamics

Results in Engineering
The quaternion wavefunction formulation for three-dimensional incompressible flow is specialised here to planar airfoil flow. In the irrotational sector the parent wavefunction factorises into a unit quaternion carrying the velocity and a complex scalar ...
