We present direct local-probe evidence for strongly hybridized nuclear-electronic spin states of an Ising ferromagnet ${\mathrm{LiHoF}}_{4}$ in a transverse magnetic field. The nuclear-electronic states are addressed via a magnetic resonance in the GHz frequency range using coplanar resonators and a vector network analyzer. The magnetic resonance spectrum is successfully traced over the entire field-temperature phase diagram, which is remarkably well reproduced by mean-field calculations. Our… Expand

Direct Measurement of the Soft Mode Driving a Quantum Phase Transition
Quantum phase transitions in spin systems are supposed to be accompanied by a soft collective mode, which has not been seen in experiments. Here, we directly measure the low energy excitation modesExpand
Thermodynamics of a quantum Ising system coupled to a spin bath
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. Results are derived for the thermodynamic properties and responseExpand
Partitioned density matrices and entanglement correlators
The density matrix of a non-relativistic quantum system, divided into $N$ sub-systems, is rewritten in terms of the set of all partitioned density matrices for the system. For the case where theExpand

TLDR
I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
