Local spin magnetization in itinerant non-collinear magnets: The local spin Berry curvature
Doru Sticlet, Frédéric Piéchon
Conventionally, the local spin magnetization in itinerant magnets is determined from the equilibrium local spin density. Here, we propose a thermodynamic approach in which the loca…
Correlations at higher-order exceptional points in non-Hermitian models
Doru Sticlet, Cătălin Paşcu Moca, Balázs Dóra
We investigate the decay of spatial correlations of -symmetric non-Hermitian one-dimensional models that host higher-order exceptional points. Beyond a certain correl…
Non-Lifshitz invariants corrections to Dzyaloshinskii-Moriya interaction energy
Doru Sticlet, Frédéric Piéchon
We study the continuum limit of two-dimensional chiral magnets in which Dzyaloshinskii-Moriya interaction (DMI) is due to the interplay between a smooth magnetic texture and spin-o…
Non-hermitian off-diagonal magnetic response of Dirac fermions
Roberta Zsófia Kiss, Doru Sticlet, Catalin Pascu Moca +1
We perform a comparative study for the magnetization dynamics within linear response theory of one and two dimensional massive Dirac electrons, after switching on either a real (he…
Quantum transport through a quantum dot side-coupled to a Majorana bound state pair in the presence of electron-phonon interaction
Levente Máthé, Doru Sticlet, Liviu P. Zârbo
We theoretically study quantum transport through a quantum dot coupled to Majorana bound states confined at the ends of a topological superconducting nanowire. The topological supe…
Non-Hermitian Lindhard function and Friedel oscillations
Balázs Dóra, Doru Sticlet, Cătălin Paşcu Moca
The Lindhard function represents the basic building block of many-body physics and accounts for charge response, plasmons, screening, Friedel oscillation, RKKY interaction etc. Her…
