Quantum field theory is by far the most spectacularly successful theory in physics, but also one of the most mystifying. Quantum Field Theory, as Simply as Possible provides an essential primer on the subject, giving readers the conceptual foundations they need to wrap their heads around one of...
和徐一鸿聊量子场论与物理直觉 7月11日,当代著名华裔物理学家、科普作家徐一鸿(Anthony Zee)教授与广大读者见面,向读者介绍自己近年出版的2本英文原版书: Quantum Field Theory, as Simply as Po - 返朴于20240712发布在抖音,已经收获了14.3万个喜欢,来抖音,记录美
Consistent reasoning as required byAssumption (C). If a theory T (such as quantum theory) enables consistent reasoning (C) then it must allow any agent A to promote the conclusions drawn by another agent A' to his own conclusions, provided that A' has the same initial knowledge about the ...
both conceptually and physically. Presently not a single example of an interacting non-perturbative Lagrangian quantum field theory has been constructed in spacetime dimension ##\geq 4## (besides numerical simulation, such as lattice gauge theory). For the case...
Recent research indicates that quantum models can more simply simulate stochastic processes that evolve independently of input.8–10 Can quantum theory also surpass classical limits in modeling general processes that behave differently on different input? Here, we present systematic methods to construct ...
K0particles appear in thebeamsimply becauseK1andK2decay at different rates. At point B, the beam enters a block of absorbing material. Both theK0andK0are absorbed by the nuclei in the block, but theK0are absorbed more strongly. As a result, even though the beam is an equal mixture ofK0...
For tasks like adding a set of numbers, the most effective method is simply adding them up. In such cases, classical computers are just as efficient as quantum computers. 11. Data in a quantum state cannot be copied Data encoded in a quantum state exhibits a unique characteristic: it cannot...
…because any unified field theory first must absorb the Riemannian geometry of Einstein’s theory and the Lie groups coming from quantum field theory… The new mathematics, which is responsible for the merger of these two theories, is topology, and it is responsible for accomplishing the ...
In consultation with outside experts in the quantum field, the Azure Quantum team wanted to set the highest possible bar and clearly establish what objective criteria would show that they’d established the long-sought-after topological phase. In particular, they wanted to avoid uncertainties such ...
Causal reasoning is essential to science, yet quantum theory challenges it. Quantum correlations violating Bell inequalities defy satisfactory causal explanations within the framework of classical causal models. What is more, a theory encompassing quantu
