Theory of Superconductivity in the Cuprates
Vivek Aji, Arkady Shekhter, Chandra Varma
The quantum critical fluctuations of the time-reversal breaking order parameter which is observed in the pseudogap regime of the Cuprates are shown to couple to the lattice equival…
A new spin-anisotropic harmonic honeycomb iridate
Kimberly A. Modic, Tess E. Smidt, Itamar Kimchi +14
The physics of Mott insulators underlies diverse phenomena ranging from high temperature superconductivity to exotic magnetism. Although both the electron spin and the structure of…
Topological Excitations of Hidden Order in URuSi Under Extreme Electric Fields
Laurel E Winter, Arkady Shekhter, Brad Ramshaw +5
Quantum materials are epitomized by the influence of collective modes upon their macroscopic properties. Relatively few examples exist, however, whereby coherence of the ground-sta…
Observation of the Yamaji effect in a cuprate superconductor
Mun K. Chan, Katherine A. Schreiber, Oscar E. Ayala-Valenzuela +3
The pseudogap state of high- cuprates, known for its partial gapping of the Fermi surface above the superconducting transition temperature , is believed to ho…
One-Component Order Parameter in URuSi Uncovered by Resonant Ultrasound Spectroscopy and Machine Learning
Sayak Ghosh, Michael Matty, Ryan Baumbach +6
The unusual correlated state that emerges in URuSi below T = 17.5 K is known as "hidden order" because even basic characteristics of the order parameter, such as its…
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…
