What is so unique in TlCuCl$_3$ which drives so many unique magnetic properties, such as a massive Higgs mode at the magnetic critical point, long-lived paramagnons, and dimerized antiferromagnetism? To study these properties, we emply here a combination of {\it ab-initio} band structure, tight-binding parameterization, and an effective quantum field theory. Within a density-functional theory (DFT) calculation, we find an unexpected bulk Dirac cone without spin-orbit coupling (SOC). Tracing…

Quantum Phase Transitions
We give a general introduction to quantum phase transitions in strongly-correlated electron systems. These transitions which occur at zero temperature when a non-thermal parameter $g$ like pressure,
