Correlations at PT-symmetric quantum critical point
Balázs Dóra, Doru Sticlet, Catalin Pascu Moca
We consider a PT-symmetric Fermi gas with an exceptional point, representing the critical point between PT-symmetric and symmetry broken phases. The low energy spectrum remains lin…
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…
Kubo formula for non-Hermitian systems and tachyon optical conductivity
Doru Sticlet, Balázs Dóra, Cătălin Paşcu Moca
Linear response theory plays a prominent role in various fields of physics and provides us with extensive information about the thermodynamics and dynamics of quantum and classical…
