STEP 聚变能 聚变能源工厂
2024/2/17
英国工业聚变解决方案有限公司 (UKIFS) 首任首席执行官 Paul Methven 详细介绍了英国原型聚变能源工厂的发展前景。
Some classical computers have error correction built into their memories based on bits; quantum computers, to be workable in the future, will need error correction mechanisms, too, based on the vastly...
In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus in the field, especially in the race for super-fast quantum computers.
Wakanda, the mythical setting for Marvels’ superhero film “Black Panther,” is home to some not-so-mythical technology. An indestructible cape might not yet be possible, but Wakanda’s levitating high-s...
ALICE takes the next step in understanding the interaction between hadrons（图）
ALICE 强子 相互作用
2021/11/17
In an article recently published in Physical Review Letters, the ALICE collaboration has used a method known as femtoscopy to study the residual interaction between two-quark and three-quark particles...
Ateam of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operati...
One-step generation of multipartite entanglement among nitrogen-vacancy center ensembles
One-step generation multipartite entanglement nitrogen-vacancy center ensembles
2016/1/22
We describe a one-step, deterministic and scalable scheme for creating macroscopic arbitrary entangled coherent states (ECSs) of separate nitrogen-vacancy center ensembles (NVEs) that couple to a supe...
We study macroscopic aspects of crystal surface relaxation in 2+1 dimensions by accounting for nearequilibrium kinetics of transparent steps at the nanoscale. For slowly varying step geometries, we sh...

2015/10/16
Mathematical implications of adding Gaussian white noise to the Burton– Cabrera–Frank model for N terraces (‘gaps’) on a crystal surface are studied under external material deposition for large N. The...

TALLAHASSEE, Fla. – Researchers from Columbia University working at the National High Magnetic Field Laboratory (MagLab) have observed a physical phenomenon in bilayer graphene that could usher in a n...
Multi-step magnetization of the Ising model on a Shastry–Sutherland lattice:a Monte Carlo simulation
Multi-step magnetization Ising model Shastry–Sutherland lattice Monte Carlo simulation
2012/5/24
The magnetization behaviors and spin configurations of the classical Ising model on a Shastry-Sutherland lattice are investigated using Monte Carlo simulations, in order to understand the fascinating ...
A Bloch decomposition based split-step pseudo spectral method for quantum dynamics with periodic potentials
Schrodinger equation Bloch decomposition time-splitting spectral method semiclassical asymptotics lattice potential
2012/5/2
We present a new numerical method for accurate computations of solutions to (linear) one dimensional Schr\"odinger equations with periodic potentials. This is a prominent model in solid state physics ...
Improved preservation of autocorrelative structure in surrogate data using an initial wavelet step

2009/11/2
Surrogate data generation algorithms are useful for hypothesis testing or for generating realisations of a process for data extension or modelling purposes. This paper tests a well known surrogate dat...
Surface-Wave Instabilities in a Plasma Rotating with Step-like Frequency Profile
Magnetorotational instability Plasma rotational instability
2009/3/31
An approach for the theory of nonlocal magnetorotational and convective instabilities in a rotating plasma is developed, on the basis of the surface wave concept, which allows the derivation of useful...

propagator step potential path decomposition expansion
2009/1/22
We present a direct path integral derivation of the propagator in the presence of a step potential. The derivation makes use of the Path Decomposition Expansion (PDX), and also of the definition of th...
