Yue Zhang: Neutrino Self-interaction: Motivations and Future Probes
Yue Zhang: Neutrino Self-interaction: Motivations and Future Probes
Neutrino self-interaction with a larger “Fermi constant” is often resorted for understanding puzzles of our universe. I will first discuss how novel neutrino self-interactions can save the sterile neutrino dark matter produced through early universe oscillation mechanism, which is otherwise … Read More

Angelo Rosa, “Configurational entropy of random trees”
Angelo Rosa, “Configurational entropy of random trees”
In this talk, I will illustrate two recent results of our group concerning the statistical physics of branched polymers. In the first part, I will present a graph theoretical approach to the configurational statistics of random tree-like objects, which is based … Read More

Marko Malezic: Toward Efficient Trotter-Suzuki Schemes for Long-Time Quantum Dynamics
Marko Malezic: Toward Efficient Trotter-Suzuki Schemes for Long-Time Quantum Dynamics
Accurately simulating long-time dynamics of quantum many-body systems—whether in real or imaginary time—is a challenge in both classical and quantum computing due to the accumulation of Trotter errors. While low-order Trotter-Suzuki decompositions are straightforward to implement, their rapidly growing error … Read More

Motoo Suzuki: Small Instantons and the Post-Inflationary QCD Axion in a Special Product GUT
Motoo Suzuki: Small Instantons and the Post-Inflationary QCD Axion in a Special Product GUT
In this talk, after some review of axion physics, I would like to discuss our recent work about a new framework of grand unification that is equipped with an axion solution to the strong CP problem without a domain wall … Read More
