In LiHo x Y 1− x F 4, the magnetic Holmium Ho 3+ ions behave as effective Ising spins that
can point parallel or antiparallel to the crystalline c-axis. The predominant inter-Ho 3+ …

Paramagnetic correlations in the magnetic material Yb 2 Ti 2 O 7 have been investigated via
neutron scattering, revealing a [111] rod of scattering intensity. Assuming interactions …

Mesoscale patterns as observed in, for example, ferromagnets, ferroelectrics,
superconductors, monomolecular films or block copolymers, reflect spatial variations of a …

We present a theory of magnon polaritons in quantum Ising materials, and develop a
formalism describing the coupling between light and matter in an Ising system that is tuned …

We present a systematic study of the crystal-field interactions in the Li RF 4 (R= Gd, Ho, Er,
Tm, and Yb) family of rare-earth magnets. Using detailed inelastic neutron scattering …

The rare-earth material LiHoF 4 is believed to be an experimental realization of the
celebrated (dipolar) Ising model and, upon the inclusion of a transverse field B x, an …

We first present a formalism that incorporates the input-output formalism and the linear
response theory to employ cavity-magnon-polariton coupling as a spectroscopic tool for …

We review quantum phase transitions of spin systems in transverse magnetic fields taking
the examples of the spin-1/2 Ising and XY models in a transverse field. Beginning with an …

We study the effect of coupling a spin-bath environment to a system which, at low energies,
can be modeled as a quantum Ising system. A field theoretic formalism incorporating both …

The physics of the spin-glass (SG) state, with magnetic moments (spins) frozen in random
orientations, is one of the most intriguing problems in condensed matter physics. In LiHo x Y …
