Double Vibronic process in the quantum spin ice candidate Tb${}_2$Ti${}_2$O${}_7$ revealed by terahertz spectroscopy

E. Constable, R. Ballou, J. Robert +8

The origin of quantum fluctuations responsible for the spin liquid state in Tb${}_2$Ti${}_2$O${}_7$ has remained a long standing problem. By synchrotron-based terahertz measurements, we…
