Circular polarization of the cosmic microwave background induced by the optical Magnus effect on gravitational lensing
Yusuke Nishida
Polarization of the cosmic microwave background (CMB) brings out information not only on the early universe but also on the late-time large-scale structure via weak gravitational l…
Resonant two-cluster scattering in a quasi-one-dimensional Bose gas
Tomohiro Tanaka, Yusuke Nishida
We investigate two-cluster scattering in a quasi-one-dimensional Bose gas. We focus on the effective three-body interaction induced by transverse confinement, which is the leading…
Optical Magnus effect on gravitational lensing
Yusuke Nishida
The optical Magnus effect refers to transverse shift of a trajectory of light caused by its polarization and appears as a correction to geometrical optics at the linear order in wa…
Semisuper Efimov effect induced by resonant pair exchange in mixed dimensions
Yusuke Nishida
We introduce a new member to the class of semisuper Efimov effects, where an infinite number of bound states emerge with their binding energies obeying the universal scaling law $E…
Universal bound states and resonances with Coulomb plus short-range potentials
Shunta Mochizuki, Yusuke Nishida
We study charged particles in three dimensions interacting via a short-range potential in addition to the Coulomb potential. When the Bohr radius and the scattering length are much…
Universal nonlinear responses of quantum Hall systems with Galilean invariance
Tatsuya Amitani, Yusuke Nishida
We study two-dimensional systems with Galilean invariance gapped under magnetic fields. When such quantum Hall systems are coupled with external sources for charge, energy, and mom…
