Dynamic scaling and Family-Vicsek universality in the Hubbard model at infinite temperature
Cătălin Paşcu Moca, Doru Sticlet, Balázs Dóra
We study Family-Vicsek scaling of charge, spin, and energy fluctuations in the one-dimensional Hubbard model at infinite temperature. Using a quantum generating function approach,…
Dynamical correlations in a dissipative XXZ spin chain
Cătălin Paşcu Moca, Doru Sticlet, Ovidiu I. Pâţu +1
We study dynamical spin correlations in a dissipative XXZ spin chain subject to uniform local spin-loss and pumping. Starting from a mixed steady state that is featureless albeit p…
Hot but Coherent: Doublons at Infinite Temperature in the Hubbard chain
Cătălin Paşcu Moca, Balázs Dóra, Gergely Zaránd
We investigate the spectral properties and the dynamics of doublons in the one-dimensional Hubbard model at infinite temperature. Using a Chebyshev expansion approach formulated in…
Quantum Coherence in a Maximally Hot Hubbard Chain
Cătălin Paşcu Moca, Ovidiu I. Patu, Balázs Dóra +1
We present a detailed study of the real-time dynamics and spectral properties of the one-dimensional fermionic Hubbard model at infinite temperature. Using tensor network simulatio…
Dynamic scaling and Family-Vicsek universality in quantum spin chains
Cătălin Paşcu Moca, Balázs Dóra, Doru Sticlet +3
The Family-Vicsek scaling is a fundamental framework for understanding surface growth in non-equilibrium classical systems, providing a universal description of temporal surface ro…
Kardar-Parisi-Zhang scaling in the Hubbard model
Cătălin Paşcu Moca, Miklós Antal Werner, Angelo Valli +2
We explore the Kardar-Parisi-Zhang (KPZ) scaling in the one-dimensional Hubbard model, which exhibits global symmetry at half-filling, for the pseudo-charg…
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…
Transport Properties Calculation in the Superconducting State for a Quasi-Twodimensional System
C. P. Moca, E. Macocian
We performed a self-consistent calculation of the transport properties of a d-wave superconductor. We used for calculations the T-matrix approximation. The coresponding equations w…
Transport Properties Calculation for a Quasi-Bidimensional System using T-Matrix Approximation
C. P. Moca, E. Macocian
We performed a self-consistent calculation using T-Matrix approximation for a quasi-bidimensional system. We calculated the one particle spectrum function A(k,ω) in the presence of…
Renormalization group approach of itinerant electron systems near the Lifshitz point
C. P. Moca, I. Tifrea, M. Crisan
Using the renormalization approach proposed by Millis for the itinerant electron systems we calculated the specific heat coefficient for the magnetic fluctuations with susce…
