Internal entropy from heat current
Noam Schiller, Hiromi Ebisu, Gil Refael +1
We demonstrate that the effective internal entropy of quasiparticles within the non-Abelian fractional quantum Hall effect manifests in the heat current through a tunneling barrier…
Entanglement entropy of higher rank topological phases
Hiromi Ebisu
We study entanglement entropy of unusual topological stabilizer codes which admit fractional excitations with restricted mobility constraint in a manner akin to frac…
Symmetric higher rank topological phases on generic graphs
Hiromi Ebisu
Motivated by recent interests in fracton topological phases, we explore the interplay between gapped 2D topological phases which admit fractional excitations with re…
Anisotropic higher rank topological phases on graphs
Hiromi Ebisu, Bo Han
We study unusual gapped topological phases where they admit fractional excitations in the same manner as topologically ordered phases, yet their ground state degener…

Hiromi Ebisu, Bo Han
In this work, we consider 2D topologically ordered phases ( toric code and the modified surface code) on a simple hyperbolic lattice. Introducing a 2D…

Hiromi Ebisu, Masataka Watanabe
We construct the complete set of boundary states of two-dimensional fermionic CFTs using that of the bosonic counterpart. We see that there are two groups of boundary conditions, w…

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…

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…

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…
