Pairing Correlations in the two-layer attractive Hubbard Model
Aleksander Zujev, Richard T. Scalettar, George G. Batrouni +1
Studies of systems with two fermionic bands with repulsive interaction strength U have a long history, with the Periodic Anderson Model (PAM) being one of the most frequently consi…
Columnar antiferromagnetic order and spin supersolid phase on the extended Shastry-Sutherland lattice
Keola Wierschem, Pinaki Sengupta
We use large scale quantum Monte Carlo simulations to study an extended version of the canonical Shastry-Sutherland model -- including additional interactions and exchange anisotro…
Magnetic and nematic orderings in spin-1 antiferromagnets with single-ion anisotropy
Keola Wierschem, Yasuyuki Kato, Yusuke Nishida +2
We study a spin-one Heisenberg model with exchange interaction, J, uniaxial single-ion exchange anisotropy, D, and Zeeman coupling to a magnetic field, B, parallel to the symmetry…
Low temperature thermodynamic properties near the field-induced quantum critical point in DTN
Franziska Weickert, Robert Kuechler, Alexander Steppke +10
We present a comprehensive experimental and theoretical investigation of the thermodynamic properties: specific heat, magnetization and thermal expansion in the vicinity of the fie…
Intrinsic Structural Disorder and the Magnetic Ground State in Bulk EuTiO3
A. P. Petrovic, Y. Kato, S. S. Sunku +8
The magnetic properties of single-crystal EuTiO3 are suggestive of nanoscale disorder below its cubic-tetragonal phase transition. We demonstrate that electric field cooling acts t…
Dimensionality selection in a molecule-based magnet
Paul A. Goddard, Jamie L. Manson, John Singleton +12
Gaining control of the building blocks of magnetic materials and thereby achieving particular characteristics will make possible the design and growth of bespoke magnetic devices.…
