Coupled wire construction of a topological phase with chiral tricritical Ising edge modes
Chengshu Li, Hiromi Ebisu, Sharmistha Sahoo +2
Tricritical Ising (TCI) phase transition is known to occur in several interacting spin and Majorana fermion models and is described in terms of a supersymmetric conformal field the…
Fibonacci topological phase in arrays of anyonic chains
Hiromi Ebisu
Fibonacci anyon, an exotic quasi-particle excitation, plays a pivotal role in realization of a quantum computer. Starting from a topological phase, in this paper we demon…
Chiral topologically ordered insulating phases in arrays of interacting integer quantum Hall islands
Hiromi Ebisu, Rohit R. Kalloor, Alexei M. Tsvelik +1
We study networks of Coulomb-blockaded integer quantum Hall islands with even fillings ( being an integer), including cases with layers each of fillings. Allow…
Supersymmetry in the Insulating Phase of a Chain of Majorana Cooper Pair Boxes
Hiromi Ebisu, Eran Sagi, Yuval Oreg
The charging energy of a small superconducting island containing Majorana zero modes---a Majorana Cooper-pair box---induces interactions between the Majorana zero modes. Consid…
Spin liquids from Majorana Zero Modes in a Cooper Box
Eran Sagi, Hiromi Ebisu, Yukio Tanaka +2
We propose a path for constructing diverse interacting spin systems from topological nanowires in Cooper Boxes. The wires are grouped into a three-wire building block called an 'he…
All-electrical generation and control of odd-frequency s-wave Cooper pairs in double quantum dots
Pablo Burset, Bo Lu, Hiromi Ebisu +2
We propose an all-electrical experimental setup to detect and manipulate the amplitude of odd-frequency pairing in a double quantum dot. Odd-frequency pair amplitude is induced fro…
