SuperConga: an open-source framework for mesoscopic superconductivity
P. Holmvall, N. Wall Wennerdal, M. Håkansson +4
We present SuperConga, an open-source framework for simulating equilibrium properties of unconventional and ballistic singlet superconductors, confined to two-dimensional (2D) meso…
Disorder-robust phase crystal in high-temperature superconductors stabilized by strong correlations
Debmalya Chakraborty, Tomas Löfwander, Mikael Fogelström +1
The simultaneous interplay of strong electron-electron correlations, topological zero-energy states, and disorder is yet an unexplored territory but of immense interest due to thei…
Spontaneously broken translational symmetry at edges of high-temperature superconductors: thermodynamics in magnetic field
P. Holmvall, A. B. Vorontsov, M. Fogelstrom +1
We investigate equilibrium properties, including structure of the order parameter, superflow patterns, and thermodynamics of low-temperature surface phases of layered d_{x^2-y^2}-w…
Graphene plasmons: impurities and nonlocal effects
Giovanni Viola, Tobias Wenger, Jari Kinaret +1
This work analyses how impurities and vacancies on the surface of a graphene sample affect its optical conductivity and plasmon excitations. The disorder is analysed in the self-co…
Current-controlled light scattering and asymmetric plasmon propagation in graphene
Tobias Wenger, Giovanni Viola, Jari Kinaret +2
We demonstrate that plasmons in graphene can be manipulated using a DC current. A source-drain current lifts the forward/backward degeneracy of the plasmons, creating two modes wit…
Spontaneous generation of fractional vortex-antivortex pairs at single edges of high-Tc superconductors
Patric Holmvall, Tomas Löfwander, Mikael Fogelström
Unconventional d-wave superconductors with pair-breaking edges are predicted to have ground states with spontaneously broken time-reversal and translational symmetries. We use the…
