Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

Advanced Quantum Technologies, EarlyView.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Antidirected Hamiltonian paths in tournaments

Journal of Combinatorial Theory, Series B, 1972
AbstractIn this paper we present a short proof of Grünbaum's theorem concerning the existence of antidirected Hamiltonian (ADH) paths in tournaments. We also prove that, in every tournament Tn with n ≥ 12, there is an ADH path starting at any vertex.

Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2

Advanced Quantum Technologies, EarlyView.
Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

Antidirected Hamiltonian paths in tournaments

Journal of Combinatorial Theory, Series B, 1971
AbstractIt is well known that every tournament has a directed Hamiltonian path. A similar result is established concerning the existence of antidirected Hamiltonian paths in tournaments.

Designer DNA‐Based Machines

SmartBot, EarlyView.
DNA machinery represents a burgeoning frontier at the intersection of robotics and nanotechnology, evolving from static nanostructure toward dynamic nanorobots. Here, the authors review the comprehensive research pipeline of designer DNA‐based nanomachines, covering the design, analysis, and fabrication. These programmable systems enable transformative

Finite topologies and Hamiltonian paths

Journal of Combinatorial Theory, Series B, 1973
Suppose x is a finite set. This paper deals with the question of how many mutually complementary topologies X can carry. If p is a prime and |X|=p, p+1, 2p−1 or 2p, we prove that the answers are respectively p, p, 2p−1, 2p−1. The problem is shown to be related to the existence of a certain type of 1-factorization of the complete graph on an even number

Short‐Range Order and LixTM4−x Probability Maps for Disordered Rocksalt Cathodes

Small, EarlyView.
Monte Carlo mapping with a simplified cluster description framework discloses the origin of Li4${\rm Li}_4$ deficiency and unfavorable short‐range order prevalent in most DRX materials. Statistical mechanical sampling indicates that ordering quantities in the disordered state do not necessarily represent a simple attenuation of their low‐temperature ...

Influence of the Chemical Composition on the Perovskites Anharmonicity: Toward a Stable Inorganic Perovskite

Solar RRL, EarlyView.
This study investigates the effect of the chemical composition on the properties of A(BB’)(XX’)3$_3$ inorganic halide perovskites with density functional theory. By correlating distortion amplitudes with both composition and the Goldschmidt tolerance factor, we propose a pragmatic approach to designing more stable and efficient perovskites, advancing ...

Dynamic Pricing With Recommendation and Consumer Feedback

The RAND Journal of Economics, EarlyView.
ABSTRACT A long‐lived seller sells a new product of unknown value by offering prices and recommendations to short‐lived consumers in continuous time. The seller receives consumer feedback about the product at a rate that increases with the instantaneous sales volume.
