Entanglement Hamiltonian of the 1+1-dimensional free, compactified boson conformal field theory
Ananda Roy, Frank Pollmann, Hubert Saleur
Entanglement or modular Hamiltonians play a crucial role in the investigation of correlations in quantum field theories. In particular, in 1+1 space-time dimensions, the spectra of…
Quantum phases of a one-dimensional Majorana-Bose-Hubbard model
Ananda Roy, Johannes Hauschild, Frank Pollmann
Majorana zero modes (MZM-s) occurring at the edges of a 1D, p-wave, spinless superconductor, in absence of fluctuations of the phase of the superconducting order parameter, are qui…
Critical properties of the Ising model in hyperbolic space
Nikolas P. Breuckmann, Benedikt Placke, Ananda Roy
The Ising model exhibits qualitatively different properties in hyperbolic space in comparison to its flat space counterpart. Due to the negative curvature, a finite fraction of the…
Topological ordering in the Majorana Toric Code
Alexander Ziesen, Fabian Hassler, Ananda Roy
At zero temperature, a two-dimensional lattice of Majorana zero modes on mesoscopic superconducting islands exhibits a topologically-ordered toric code phase. Recently, a Landau fi…
Quantum Electronic Circuit Simulation of Generalized sine-Gordon Models
Ananda Roy, Hubert Saleur
Investigation of strongly interacting, nonlinear quantum field theories (QFT-s) remains one of the outstanding challenges of modern physics. Here, we describe analog quantum simula…
Charge response of the Majorana toric code
Ananda Roy, Fabian Hassler
At zero temperature, a two dimensional lattice of Majorana zero modes on mesoscopic superconducting islands has a topologically ordered toric code phase. Recently, a Landau field t…
