Data-Driven Modeling of S0 -> S1 Excitation Energy in the BODIPY Chemical Space: High-Throughput Computation, Quantum Machine Learning, and Inverse Design
Amit Gupta, Sabyasachi Chakraborty, Debashree Ghosh +1
Derivatives of BODIPY are popular fluorophores due to their synthetic feasibility, structural rigidity, high quantum yield, and tunable spectroscopic properties. While the characte…
Resolution-vs.-Accuracy Dilemma in Machine Learning Modeling of Electronic Excitation Spectra
Prakriti Kayastha, Sabyasachi Chakraborty, Raghunathan Ramakrishnan
In this study, we explore the potential of machine learning for modeling molecular electronic spectral intensities as a continuous function in a given wavelength range. Since prese…
Heavy QCD Axion at Belle II: Displaced and Prompt Signals
Emilie Bertholet, Sabyasachi Chakraborty, Vazha Loladze +3
The QCD axion is a well-motivated addition to the standard model to solve the strong problem. If the axion acquires mass dominantly from a hidden sector, it can be as heavy…
Composite neutrinos and the QCD axion: baryogenesis, dark matter, small Dirac neutrino masses, and vanishing neutron EDM
Sabyasachi Chakraborty, Tae Hyun Jung, Takemichi Okui
We consider a chiral gauge theory from which light composite Dirac neutrinos dynamically emerge, augmented by a QCD axion to solve the strong CP problem. We show that an interplay…
Heavy QCD Axion in transition: Enhanced Limits and Projections
Sabyasachi Chakraborty, Manfred Kraus, Vazha Loladze +2
We study a "heavy" QCD axion whose coupling to the standard model is dominated by but with . This is well motivated as it can solve the str…
