Sound attenuation and velocity shift in antiferromagnetic spin-1/2 chains

Edmond Orignac, Emeric Caprani, Roberta Citro

We investigate ultrasound attenuation and sound velocity shift in antiferromagnetic spin-1/2 XXZ chains in magnetic field. We relate the sound velocity shift to derivatives of the…
