Confinement-induced p-wave resonances from s-wave interactions
Yusuke Nishida, Shina Tan
We show that a purely s-wave interaction in three dimensions (3D) can induce higher partial-wave resonances in mixed dimensions. We develop two-body scattering theories in all thre…
Counting Majorana zero modes in superconductors
Luiz Santos, Yusuke Nishida, Claudio Chamon +1
A counting formula for computing the number of (Majorana) zero modes bound to topological point defects is evaluated in a gradient expansion for systems with charge-conjugation sym…
Topological superconductors as nonrelativistic limits of Jackiw-Rossi and Jackiw-Rebbi models
Yusuke Nishida, Luiz Santos, Claudio Chamon
We argue that the nonrelativistic Hamiltonian of p_x+ip_y superconductor in two dimensions can be derived from the relativistic Jackiw-Rossi model by taking the limit of large Zeem…
Unitary Fermi gas, epsilon expansion, and nonrelativistic conformal field theories
Yusuke Nishida, Dam Thanh Son
We review theoretical aspects of unitary Fermi gas (UFG), which has been realized in ultracold atom experiments. We first introduce the epsilon expansion technique based on a syste…
Scattering in Mixed Dimensions with Ultracold Gases
G. Lamporesi, J. Catani, G. Barontini +3
We experimentally investigate the mix-dimensional scattering occurring when the collisional partners live in different dimensions. We employ a binary mixture of ultracold atoms and…
Quantizing Majorana Fermions in a Superconductor
C. Chamon, R. Jackiw, Y. Nishida +2
A Dirac-type matrix equation governs surface excitations in a topological insulator in contact with an s-wave superconductor. The order parameter can be homogenous or vortex valued…
