1. Does there is broken time-reversal symmetry in Chern insulator or time-reversal symmetry in Chern insulator is preserved ? 2. Does Chern insulator is the topological insulator or it is not such ?

Hi all My question: I have read: Topological Insulators: Dirac Equation in Condensed Matters But also I have read: Observation of a Discrete Time Crystal Is it different situations ?

Yes. In my mind the result of any quantum measurement is the collapse of superposition

Hi all My question: One of the four Bell's state are measuring in the Bell basis. Whether the result of measurement of this one of the four Bell's state will be the same Bell's state (just that Bell's state which are measuring) ? The each of four Bell's state is a quantum superposition of the...

In Graph States for Quantum Secret Sharing on page 3 : I understand that $$\mathop \otimes \limits_i Z_i^{{l_{i2}}} = Z_1^{{l_{12}}} \otimes Z_2^{{l_{22}}} \otimes Z_3^{{l_{32}}}$$ But I don’t understand why $$\left| G \right\rangle = \left( {\frac{{\left| {0 + + } \right\rangle +...

Homework Statement There are three qutrits which are connected by quantum entanglement: |\Psi\rangle=\frac{1}{\sqrt{3}}\left( {|021\rangle+|102 \rangle+ |102 \rangle} \right) How can I to describe \langle\Psi| ? \langle\Psi|=\frac{1}{\sqrt{3}}\left( {\langle ... |+\langle ... | +...

What are the rules of analytical – not numerical (matrix) entry of bra-ket convertion – operations on bra-ket, in particular – tensor product ? For example – how in analytical form to do this: U|\Psi\rangle where: U=I\otimesI I=|0\rangle\langle0|+|1\rangle\langle1|...

Decoherence? Why ? How ? :confused:

Is already anything in arXiv ?

Advise a textbook on an inflammation, please. I search textbook or monography of famous author. Help me please. It is desirable edition not earlier than 2007-2008 P. S. I ask to exuse me for my bad English

Hello all ! My question: Does fibre bundles are necessary for describing gauge invariance in electromagnetic case? Or fibre bundles uses only for describing gauge invariance in cases of weak, electroweak and strong interactions? Thanks

But when we go by the open car (cabriolet) we feel a motion of molecules of air - a wind to the face Why it is not so when Earth rotates ? :confused:

Hello all ! Why on a surface of the Earth the calm is possible? The Earth rotates about (аround) the axis. Why air molecules are motionless concerning the Earth?
