What is a Sound Wave in Physics?In physiology, sound is produced when an object’s vibrations move through a medium until they enter an eardrum. In physics, sound is produced in the form of a pressure wave. When an object vibrates, it causes the surrounding air molecules to vibrate, init...
Already for the simple case of a particle with spin 1/2 you would need two such wavefunctions (one for the spin up and one for the spin down). I won’t go too deep into it, but the wavefunction of a system is a function that assigns to each result of (compatible) measurements, a...
we and all of the objects around us are ultimately constituted out of the wave function and although we may seem to occupy a three-dimensional space of the kind described by classical physics, the more fundamental spatial framework of quantum worlds like ours is instead quite different, one of...
The appearance of wavefunctions in a context that is free of the complexities of quantum mechanics suggests the study of such models may shed some light on interpretive issues.doi:10.1016/j.aop.2009.03.007G.N. OrdesAnnals of PhysicsOrd, G. Quantum mechanics in a two-dimensional spacetime: ...
29-14 Energy in EM wave 物理学是整个自然科学和现代工程技术的基础。英文版大学物理课程的开设,首先是使学生掌握专业所必须的物理基础知识和专业词汇;进而要让学生对物理学的内容和方法、工作语言、概念和物理图像,其历史、现状和前沿等方面,从整体上有个全面的了解。
The word "quantum" is a perfectly good word meaning a wave with minimum amplitude; why are physicists insisting on calling a quantum a particle? The word "quantum" in physics is used as a "definite quantity of a variable" in contrast to "a continuous quantity of that variable". There are...
In this Roadmap, we present the perspectives of the Gravitational Wave International Committee (GWIC,https://gwic.ligo.org) on the emerging field of GW astronomy and physics in the coming decades. The GWIC was formed in 1997 to facilitate international collaboration and cooperation in the construc...

All-to-all interacting, disordered quantum many-body models have a wide range of applications across disciplines, from spin glasses in condensed-matter physics over holographic duality in high-energy physics to annealing algorithms in quantum computing. Typically, these models are abstractions that do ...
As a future high energy nuclear physics project, an Electron-ion collider in China (EicC) has been proposed. It will be constructed based on an upgraded heavy-ion accelerator, High Intensity heavy-ion Accelerator Facility (HIAF) which is currently under construction, together with a new electron...
