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…
Electric field gradient in accurate quantum chemical calculations
Andrei Derevianko, U. C. Perera, Marek Krośnicki +3
The electric field gradients (EFGs) at the (non-spherical) nucleus contribute to atomic and molecular hyperfine structure and govern Nuclear Quadrupole Resonance (NQR) and Mössbaue…
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…
Bottom-up approach to scalable growth of molecules capable of optical cycling
Guanming Lao, Taras Khvorost, Antonio Macias +10
Gas-phase molecules capable of repeatable, narrow-band spontaneous photon scattering are prized for direct laser cooling and quantum state detection. Recently, large molecules inco…
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…
229Th-doped nonlinear optical crystals for compact solid-state clocks
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…
