Anomalous and Anisotropic Nonlinear Susceptibility in the Proximate Kitaev Magnet -RuCl
Ludwig Holleis, Joseph Prestigiacomo, Zhijie Fan +5
The leading order nonlinear (NL) susceptibility, , in a paramagnet is negative and diverges as . This divergence is destroyed when spins correlate and the NL…
Magneto Acoustic Quantum Oscillations in High Fields and the Fermi Surface of UPt
Ludwig Holleis, V. W. Ulrich, B. S. Shivaram
We report magneto-acoustic quantum oscillations (MAQO) in the heavy fermion system UPt in magnetic fields B, upto 33 T. For B in the ab-plane of the hexagonal crystal MAQO in t…
Field Angle Tuned Metamagnetism and Lifschitz Transitions in UPt3
B. S. Shivaram, Ludwig Holleis, V. W. Ulrich +2
Strongly correlated electronic systems can harbor a rich variety of quantum spin states. Understanding and controlling such spin states in quantum materials is of great current int…
An Effective Spin Hamiltonian Approach to Metamagnetism - I
P. Kumar, B. S. Shivaram, V. Celli
We describe a minimal model, based on a spin only Hamiltonian with a single energy scale for itinerant electron metamagnetism. Within this model the metamagnetic critical field is…
A Model for Correlated Metamagnets: Application to UPt and CeRuSi
Bellave Shivaram
In a model system with three S=1 pseudo-spins situated in an anisotropic mean field we compute the thermodynamic response in a self consistent manner. An adhoc uniform broadening o…
The CeMIn5 (M = Rh, Ir and Co) System and the Single Energy Scale Model of Metamagnetism
A. Thamizhavel, B. D. White, M. B. Maple +5
For a decade and a half, CeCoIn and related alloys have served as a rich playground to explore the interplay between magnetism and unconventional superconductivity. Despite thi…
