Universal Planckian relaxation in the strange metal state of the cuprates
A. Shekhter, B. J. Ramshaw, M. K. Chan +1
A major puzzle in high- superconductivity is the origin of the ``Planckian'' relaxation rate underlying the linear-in-temperature resistivity in the strange-metal…
Slow spin-lattice relaxation dynamics in YbVO4 revealed by extended thermal impedance spectroscopy from AC susceptibility and AC magnetocaloric measurements
Yuntian Li, Jiayi Hu, Dominic Petruzzi +4
Alternating (AC) magnetic fields can induce not only an alternating magnetization in materials, but also an alternating temperature via the magnetocaloric effect. The latter effect…
Magnetic field-temperature competition and quantum criticality in a strange metal
A. Khansili, A. Bangura, R. D. McDonald +3
Strange metals defy the quasiparticle description of conventional metals, exhibiting a linear in temperature (-linear) resistivity in a broad temperature range. It has become in…
Homes' Law and Universal Planckian Relaxation
A. Shekhter, M. K. Chan R. D. McDonald, N. Harrison
According to Zaanen's interpretation of Homes' empirical law~[Zaanen, {\it Nature} {\bf 430}, 512 (2004)], the superconducting transition temperatures in the cuprates are high beca…
Giant transverse magnetic fluctuations at the edge of re-entrant superconductivity in UTe
Valeska Zambra, Amit Nathwani, Muhammad Nauman +6
UTe exhibits the remarkable phenomenon of re-entrant superconductivity, whereby the zero-resistance state reappears above 40 tesla after being suppressed with a field of arou…
Realization of discretized response in rare-earth vanadates accessed by AC susceptibility and magnetocaloric methods
Yuntian Li, Linda Ye, Mark P. Zic +2
This report presents a new technique to probe the quantitative dynamical response of the magnetic field induced heating/cooling process in rare-earth vanadium materials. The approa…
