Strengthened correlations near [110] edges of -wave superconductors in the t-J model with the Gutzwiller approximation
Ambjorn Joki, Mikael Fogelstrom, Tomas Lofwander
We report results of a study of strongly correlated -wave superconducting slabs within a t-J model solved using the statistically consistent Gutzwiller approach. For different d…
Impurity strength-temperature phase diagram with phase crystals and competing time-reversal symmetry breaking states in nodal -wave superconductors
Kevin Marc Seja, Niclas Wall-Wennerdal, Tomas Löfwander +3
Phase crystals are a class of nonuniform superconducting ground states characterized by spontaneous phase gradients of the superconducting order parameter. These phase gradients no…
Spontaneous splitting of d-wave surface states: Circulating currents or edge magnetization?
Kevin Marc Seja, Niclas Wall-Wennerdal, Tomas Löfwander +1
Pair-breaking edges of -wave superconductors feature Andreev bound states at the Fermi energy. Since these states are energetically highly unfavorable they are susceptible to ef…
Highly efficient UV detection in a metal-semiconductor-metal detector with epigraphene
Hans He, Naveen Shetty, Sergey Kubatkin +7
We show that epitaxial graphene on silicon carbide (epigraphene) grown at high temperatures (T > 1850 °C) readily acts as material for implementing solar-blind ultraviolet (UV) det…
Thermopower and thermophase in a -wave superconductor
Kevin Marc Seja, Louhane Jacob, Tomas Löfwander
In an unconventional superconductor, the interplay of scattering off impurities and Andreev processes may lead to different scattering times for electronlike and holelike quasipart…
Transport through vertical graphene contacts under intense laser fields
Pascal Stadler, Tomas Löfwander, Mikael Fogelström
We theoretically study the electronic and transport properties of two graphene layers vertically coupled by an insulating layer under the influence of a time-periodic external ligh…
