Defect assignment of the clock site in
Daniel A. Rehn, Harry W. T. Morgan, Harris E. Mason +6
The performance of solid-state nuclear clocks depends sensitively on the microscopic environment of the thorium nucleus in the host crystal. Here we reassess the…
Ab initio calculations of Th band-to-band internal conversion rate in ThO
Udeshika C. Perera, H. B. Tran Tan, H. W. T. Morgan +3
We present an ab initio calculation of the band-to-band internal-conversion rate of the eV isomeric transition in ThO. Because the nucle…
A cryogenic Paul trap for probing the nuclear isomeric excited state Th
Daniel Moritz, Kevin Scharl, Markus Wiesinger +16
While laser excitation of the nuclear isomeric transition in Th has been recently achieved for thorium atoms embedded in large-bandgap crystals, laser excitation and charac…
Th Nuclear Spectroscopy in an Opaque Material: Laser-Based Conversion Electron Mössbauer Spectroscopy of ThO
Ricky Elwell, James E. S. Terhune, Christian Schneider +11
Here, we report the first demonstration of laser-induced conversion electron Mössbauer spectroscopy of the Th nuclear isomeric state, which provides the ability to probe th…
Host-dependent frequency offsets in Th nuclear clockwork
U. C. Perera, H. W. T. Morgan, Eric R. Hudson +1
Recent advances in laser excitation of the low-energy nuclear isomer transition in Th have opened avenues for developing nuclear clocks, a novel quantum technology with exc…
Investigation into thorium sulfate as a spinless crystal for a high-performance solid-state nuclear clock
Harry W. T. Morgan, James E. S. Terhune, Albert Bao +9
The isotope has a laser-accessible nuclear transition allowing the construction of a solid-state nuclear clock. Solid-state nuclear clock development has focu…
Photo-Induced Quenching of the 229Th Isomer in a Solid-State Host
J. E. S. Terhune, R. Elwell, H. B. Tran Tan +5
The population dynamics of the 229Th isomeric state is studied in a solid-state host under laser illumination. A photoquenching process is observed, where off-resonant vacuum-ultra…
Theory of internal conversion of the thorium-229 nuclear isomer in solid-state hosts
H. W. T. Morgan, H. B. Tran Tan, R. Elwell +3
Laser excitation of thorium-229 nuclei in doped wide bandgap crystals has been demonstrated recently, opening the possibility of developing ultrastable solid-state clocks and sensi…

H. W. T. Morgan, R. Elwell, J. E. S. Terhune +5
The recent laser excitation of the 229Th isomeric transition in a solid-state host opens the door for a portable solid-state nuclear optical clock. However, at present the vacuum-u…
thin films for solid-state nuclear clocks
Chuankun Zhang, Lars von der Wense, Jack F. Doyle +11
After nearly fifty years of searching, the vacuum ultraviolet Th nuclear isomeric transition has recently been directly laser excited [1,2] and measured with high spectrosc…
Radiative Decay of the Th Nuclear Clock Isomer in Different Host Materials
S. V. Pineda, P. Chhetri, S. Bara +42
A comparative vacuum ultraviolet spectroscopy study conducted at ISOLDE-CERN of the radiative decay of the Th nuclear clock isomer embedded in different host materials is…
