In quantum field theory the concept of a Lagrangian interaction density, expressed in terms of fields, is primary. Forces between two particles are regarded as arising primarily from the exchange of quanta of the bosonic fields. Thus, in contrast to nonrelativistic quantum mechanics, the concept ...
At the deepest levels of quantum theory, what is happening here is an example of complementarity:...

We discuss different interpretations of the particle production in quantum fields theory. We study in detail the "instantaneous Hamiltonian diagonalization method" and the "adiabatic vacuum prescription" and we show the difference between both methods calculating the particle production in the flat Friedman...
The fact that this surface potential is not a bending invariant (cannot be expressed as a function of the components of the metric tensor and their derivatives) is also interesting from the more general point of view of the quantum mechanics in curved spaces, since it can never be obtained ...

这一部分是我学习凝聚态场论(condense matter field theory --Altland and simons)时所作的笔记,上传到知乎一是为了自我总结,因为我是一个很不爱把总结写下来的人,总是喜欢在脑子里空想,这样的坏处是容易忘,上传到知乎上能够被人观看,那总结这件事就变得有趣了,这会让我更有动力。二是我作为一个学生,从小书堆...
Nevertheless, it is possible to represent the idea of quantum indistinguishability with a first-order language using quasiset theory (Q). In this work, we show that Q cannot capture one of the most important features of quantum non-individuality, which is the fact that there are quantum ...
