Friedel oscillations in a two-dimensional electron gas and monolayer graphene with a non-Coulomb impurity potential
Levente Máthé, Ioan Grosu
We study Friedel oscillations in a two-dimensional non-interacting electron gas and in a monolayer graphene in the presence of a single impurity. The potential generated by the imp…
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…
Phonon-Assisted Tunneling through Quantum Dot Systems Connected to Majorana Bound States
Levente Máthé, Zoltán Kovács-Krausz, Ioan Botiz +4
We theoretically analyze phonon-assisted tunneling transport in a quantum dot side connected to a Majorana bound state in a topological superconducting nanowire. We investigate the…
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…
Helical and topological phase detection based on nonlocal conductance measurements in a three terminal junction
P. Wójcik, D. Sticlet, P. Szumniak +1
The helical state is a fundamental prerequisite for many spintronics applications and Majorana zero mode engineering in nanoscopic semiconductors. Its existence in quasi-one-dimens…
Linear and nonlinear optical properties in spherical quantum dots: Inversely quadratic Hellmann potential
L. Máthé, C. P. Onyenegecha, A. -A. Farcaş +3
The aims of the reported work are to provide new insights into the quantum dot optical properties confined in an inverse of a quadratic Hellmann potential. The Schrödinger equation…
SQUID pattern disruption in transition metal dichalcogenide Josephson junctions due to non-parabolic dispersion of the edge states
D. Sticlet, P. Wójcik, M. P. Nowak
We theoretically study Josephson junctions with a transition metal dichalcogenide zigzag ribbon as a weak link. We demonstrate that the spatial profile of the supercurrent carried…
All-electrical spectroscopy of topological phases in semiconductor-superconductor heterostructures
Doru Sticlet, Cătălin Paşcu Moca, Balázs Dóra
Semiconductors in the proximity of superconductors have been proposed to support phases hosting Majorana bound states. When the systems undergo a topological phase transition towar…
Valley polarized current and resonant electronic transport in a non-uniform zigzag nanoribbon
D. Gut, M. Prokop, D. Sticlet +1
Using the tight-binding approach we study the electronic transport in a zigzag ribbon with a spatially varying potential profile. Considering a ribbon with a smoot…

Doru Sticlet, Cristian Morari
Recent experimental studies have found that magnetic impurities deposited on superconducting monolayer NbSe generate coupled Yu-Shiba-Rusinov bound states. Here we consider fer…
Nonequilibrium Kondo effect in a graphene-coupled quantum dot in the presence of a magnetic field
Levente Máthé, Ioan Grosu
Quantum dots connected to larger systems containing a continuum of states like charge reservoirs allow the theoretical study of many-body effects such as the Coulomb blockade and t…
