Magnetic excitation spectrum of the highly dimerised antiferromagnet BaCu2V2O...

In the conventional picture magnetic excitations broaden with increasing temperature with a symmetric Lorentzian lineshape. However very recently asymmetric thermal lineshape...在常规的认知图景中，磁激发随温度升高而展宽，且具有对称洛伦兹（Lorentzian）线型。然而近期的研究却发现了非对称热线型……
