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…
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…
Dual Shapiro steps of a phase-slip junction in the presence of a parasitic capacitance
Lisa Arndt, Ananda Roy, Fabian Hassler
Bloch oscillations in a single Josephson junction in the phase-slip regime relate current to frequency. They can be measured by applying a periodic drive to a DC-biased, small Jose…
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…
Quantum phase transitions of the Majorana toric code in the presence of finite Cooper-pair tunneling
Ananda Roy, Barbara M. Terhal, Fabian Hassler
The toric code based on Majorana fermions on mesoscopic superconducting islands is a promising candidate for quantum information processing. In the limit of vanishing Cooper-pair t…
