Quantum complexity and the virial theorem

Journal of High Energy Physics, 2018
It is conjectured that in the geometric formulation of quantum computing, one can study quantum complexity through classical entropy of statistical ensembles established non-relativistically in the group manifold of unitary operators.

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

Advanced Functional Materials, EarlyView.
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

Bulk‐Like Spin Cycloid and Fast Switching in Freestanding BiFeO3

Advanced Functional Materials, EarlyView.
Freestanding BiFeO3 membranes overcome substrate‐induced constraints by simultaneously restoring the intrinsic bulk‐like spin cycloid and enabling ≈50% faster ferroelectric switching than substrate‐clamped epitaxial thin films. This combination of robust noncollinear antiferromagnetic order and efficient electric‐field switching establishes ...

Thermodynamic costs of Turing machines

Physical Review Research, 2020
Turing machines (TMs) are the canonical model of computation in computer science and physics. We combine techniques from algorithmic information theory and stochastic thermodynamics to analyze the thermodynamic costs of TMs.

Interface‐Mediated Catalysis for Improved Hydrogen Storage in Reactive Hydride Composites

Advanced Materials, EarlyView.
Catalyst–hydride interfaces are engineered in Co@C‐ and Ni@C‐modified 2LiH + MgB2 reactive hydride composites to accelerate hydrogen uptake and release. Multiscale scattering, in‐situ synchrotron radiation powder x‐ray diffraction and density functional theory calculations reveal the structural and electronic origin of the catalytic enhancement ...

Measuring linguistic complexity in Chinese: An information-theoretic approach

Humanities & Social Sciences Communications
The measurement of linguistic complexity has been a heated topic in linguistics. While previous studies have mainly centered around English and other European languages, Chinese seems neglected to some extent, and the existing Chinese linguistic ...

Process Complexity [PDF]

, 2021
We develop the ontology of “process complexity” and describe how the dynamics of “becoming” can be framed as the emerging, stabilising, and ultimate dissolving of “patterns of relationships.” By extending traditional complexity thinking through ...

Physics‐Informed Neural Network‐Enabled Forward Prediction and Inverse Design of Ring Origami

Advanced Science, EarlyView.
This work presents a KRT‐PINN framework that integrates Kirchhoff rod theory with physics‐informed neural networks for the forward prediction and inverse design of ring origami consisting of closed‐loop rods. The framework predicts stable states of segmented rings with prescribed natural‐curvature profiles and determines the natural‐curvature profiles ...
