Quantum Phase Transitions in 1D Chain Materials

A quantum phase transition (QPT) is a phase transition between different states of quantum matter, such as complex magnetism, superconductivity, and charge density wave states. In a continuous, second-order phase transition between quantum phases, fluctuations occur near a quantum critical point (QCP). These quantum critical points are often amplified by magnetic frustration and represent a viable mechanism to high temperature superconductivity. By studying quasi-low-dimensional bulk solids and their continuous quantum phase transitions, we will utilize synthetic solid-state chemistry to determine the role these fluctuations play in emergent quantum states.
