The prospect of laser cooling polyatomic molecules has opened a new avenue in the search for electric dipole moment electron (eEDM). An upper bound on eEDM would probe physics arising from beyond Standard Model elementary particles. In this work, we report first theoretical results effective field experienced by YbOH, and its molecular moment, using relativistic coupled cluster theory. We compare these two properties YbOH with YbF, which also singly unoccupied orbital Yb ion. present...
Abstract Spectral characterization of noise environments that lead to the decoherence qubits is critical developing robust quantum technologies. While dynamical decoupling offers one most successful approaches characterize spectra, it necessitates applying large sequences π pulses increase complexity and cost method. Here, we introduce a spectroscopy method utilizes only Fourier transform free induction decay or spin echo measurements, thus removing need for application many pulses. We show...
We report theoretical results of the electric dipole moment (EDM) $^{210}$Fr which arises from interaction EDM an electron with internal field in atom and scalar-pseudoscalar electron-nucleus interaction; two dominant sources CP violation this atom. Employing relativistic coupled-cluster theory, we evaluate enhancement factors for these violating interactions to accuracy about 3% analyze contributions many-body effects. These quantities combination projected sensitivity experiment provide...
Abstract Flare frequency distributions represent a key approach to addressing one of the largest problems in solar and stellar physics: determining mechanism that counterintuitively heats coronae temperatures are orders magnitude hotter than corresponding photospheres. It is widely accepted magnetic field responsible for heating, but there two competing mechanisms could explain it: nanoflares or Alfvén waves. To date, neither can be directly observed. Nanoflares are, by definition, extremely...
We show that the early time dynamics of easy-axis magnetic domain formation in a spinor condensate is described by percolation theory. These could be initialized using quench spin-dependent interaction parameter. propose scheme to observe same quenching quadratic Zeeman energy and applying generalized spin rotation ferromagnetic spin-1 condensate. Using simulations we investigate finite-size scaling behavior extract correlation length critical exponent transition point. analyze sensitivity...
Detecting and characterizing decoherence-inducing noise sources is critical for developing scalable quantum technologies deploying sensors that operate at molecular scales. Yet, existing methods such spectroscopy face fundamental difficulties, including their reliance on severe approximations the need extensively averaged measurements. Here, we propose an alternative approach processes commonly performed dynamical decoupling-based coherence measurements using a novel self-consistent...
The relativistic coupled-cluster (RCC) method is a powerful many-body method, particularly in the evaluation of electronic wave functions heavy atoms and molecules, can be used to calculate various atomic molecular properties.

Electron searches using...
In this review article, we survey some of our results pertaining to the search for electric dipole moment electron (eEDM), using heavy polar molecules. particular, focus on relativistic coupled cluster method (RCCM) and its applications eEDM searches in YbF, HgX (X = F, Cl, Br, I), BaF, HgA (A Li, Na, K), YbOH.
