Direct observation of the quantum-fluctuation driven amplitude mode in a microcavity polariton condensate
Mark Steger, Ryo Hanai, Alexander Orson Edelman +7
The Higgs amplitude mode is a collective excitation studied and observed in a broad class of matter, including superconductors, charge density waves, antiferromagnets, 3He p-wave s…
Non-equilibrium strong-coupling theory for a driven-dissipative ultracold Fermi gas in the BCS-BEC crossover region
Taira Kawamura, Ryo Hanai, Daichi Kagamihara +2
We theoretically investigate strong-coupling properties of an ultracold Fermi gas in the BCS-BEC crossover regime in the non-equilibrium steady state, being coupled with two fermio…
Critical fluctuations at a many-body exceptional point
Ryo Hanai, Peter B. Littlewood
Critical phenomena arise ubiquitously in various context of physics, from condensed matter, high energy physics, cosmology, to biological systems, and consist of slow and long-dist…
