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…

Universal conductance of a PT-symmetric Luttinger liquid after a quantum quench
Cătălin Paşcu Moca, Balázs Dóra
We study the non-equilibrium dynamics and transport of a PT-symmetric Luttinger liquid (LL) after an interaction quench. The system is prepared in domain wall initial state. After…

Specific heat behavior of high temperature superconductors in the pseudogap regime
I. Tifrea, C. P. Moca
Experimental data obtained from thermodynamic measurements in underdoped high temperature superconductors show unusual anomalies in the temperature dependence of the electronic spe…
