Disorder-induced nuclear-transition doublet at nominally cubic Th sites
Andrei Derevianko
The Th nuclear clock transition is inhomogeneously broadened even at sites of nominally cubic symmetry, where the electric-field gradient of the ideal lattice vanishes. We…
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…
Suppression of differential light shifts in ground and metastable trapped-ion qubits
Drew Parks, Thomas Dellaert, Patrick McMillin +3
In the presence of a magnetic field, hyperfine clock qubits can acquire a vector differential light shift that can be tuned via polarization to suppress the total differential ligh…
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…
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…
Laser excitation of the Th nuclear isomeric transition in a solid-state host
R. Elwell, Christian Schneider, Justin Jeet +6
LiSrAlF crystals doped with Th are used in a laser-based search for the nuclear isomeric transition. Two spectroscopic features near the nuclear transition energy are o…
Eliminating qubit type cross-talk in the protocol
Samuel R. Vizvary, Zachary J. Wall, Matthew J. Boguslawski +4
The protocol is a promising paradigm that uses multiple, application-specific qubit subspaces within the Hilbert space of each single atom during quantum information…
Coupled-cluster calculations of properties of Boron atom as a monovalent system
H. Gharibnejad, A. Derevianko
We present relativistic coupled-cluster (CC) calculations of energies, magnetic-dipole hyperfine constants, and electric-dipole transition amplitudes for low-lying states of atomic…
