Time Reversal Symmetry and theZ2Index 时间反演对称性意味着 [H(r),Θ]=0 其中Θ=−iσyK是时间反演算符,K是复共轭算符。在能带理论(动量空间)中,时间反演对称性意味着 H(−k)=ΘH(k)Θ−1 因为好量子数k已经取代了哈密顿量中的动量算符p=−iℏ∇,而后者在时间反演Θ下改变了一个负号。
Time-reversal of ultrasonic fields allows a very efficient approach to focus pulsed ultrasonic waves through inhomogeneous media. Time-reversal mirrors (TRMS) are made of large transducer arrays, allowing the incident acoustic field to be sampled, time-reversed and re-emitted. The paper introduces th...
The meaning of TIME REVERSAL is a formal operation in mathematical physics that reverses the order in which a sequence of events occurs.
However, direct evidence for the time-reversal symmetry breaking of the charge order remains elusive. Here we use muon spin relaxation to probe the kagome charge order and superconductivity in KV3Sb5. We observe a noticeable enhancement of the internal field width sensed by the muon ensemble, ...
Time-reversal refocusing for waves propagating in inhomogeneous media have recently been observed and studied experimentally in various contexts (ultrasound, underwater acoustics,...); see, for instance, [M. Fink, Scientific American, November (1999), pp. 63-97]. Important potential applications hav...
