Abstract: We report the first driving of the $7s{\phantom{\rule{0.16em}{0ex}}}^{2}{S}_{1/2}\ensuremath{\rightarrow}6d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{3/2}$ and $7s{\phantom{\rule{0.16em}{0ex}}}^{2}{S}_{1/2}\ensuremath{\rightarrow}6d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{5/2}$ electric quadrupole (E2) transitions in ${\mathrm{Ra}}^{+}$. We measure the frequencies of both E2 transitions and two other low-lying transitions in $^{226}\mathrm{Ra}^{+}$ that are important for… read more here.

DOI: 10.1103/physrevb.100.024429
Abstract: Experimental studies demonstrate that the low-frequency dielectric permittivity of many magnetic materials is sensitive to the spin ordering, but the microscopic mechanisms of the observed phenomena still remain poorly understood. Here we report on the… read more here.

DOI: 10.1103/physrevb.101.235107
Abstract: The $\mathrm{spin}\text{\ensuremath{-}}\frac{1}{2}$ Heisenberg antiferromagnetic chain is ideal for realizing one of the simplest gapless quantum spin liquids (QSLs), supporting a many-body ground state whose elementary excitations are fractional fermionic excitations called spinons. Here we report… read more here.
