Non-Hermitian topology of quantum spin-Hall systems to detect edge-state polarization
Raghav Chaturvedi, Ion Cosma Fulga, Jeroen van den Brink +1
We study the non-Hermitian topology of multi-terminal transport in a quantum spin-Hall device described by the Bernevig-Hughes-Zhang model. We show that breaking time-reversal symm…
Three prerequisites for high-temperature superconductivity in t-PtBi
Andrii Kuibarov, Susmita Changdar, Riccardo Vocaturo +9
Although the generic mechanism behind high-temperature superconductivity remains notoriously elusive, a set of favorable conditions for its occurrence in a given material has emerg…
Ginzburg-Landau theory for unconventional surface superconductivity in PtBi
Harald Waje, Fabian Jakubczyk, Jeroen van den Brink +1
Recent experimental evidence suggests the presence of an unconventional, nodal surface-su\-per\-con\-duc\-ting state in trigonal PtBi\textsubscript{2}. We construct a Ginzburg--Lan…
Finite temperature fermion Monte Carlo simulations of frustrated spin-Peierls systems
João C. Inácio, Jeroen van den Brink, Fakher F. Assaad +1
The Abrikosov fermion representation of the spin-1/2 degree of freedom allows for auxiliary-field quantum Monte Carlo simulations of frustrated spin systems. This approach provides…
Non-Hermitian topology in the quantum Hall effect of graphene
Burak Özer, Kyrylo Ochkan, Raghav Chaturvedi +12
Quantum Hall phases have recently emerged as a platform to investigate non-Hermitian topology in condensed-matter systems. This platform is particularly interesting due to its tuna…
Room temperature Planar Hall effect in nanostructures of trigonal-PtBi2
Arthur Veyrat, Klaus Koepernik, Louis Veyrat +13
Trigonal-PtBi2 has recently garnered significant interest as it exhibits unique superconducting topological surface states due to electron pairing on Fermi arcs connecting bulk Wey…
Theoretical prediction of perfect spin filtering at interfaces between close-packed surfaces of Ni or Co and graphite or graphene
V. M. Karpan, P. A. Khomyakov, A. A. Starikov +6
The in-plane lattice constants of close-packed planes of fcc and hcp Ni and Co match that of graphite almost perfectly so that they share a common two dimensional reciprocal space.…
