H-NESSi: The Hierarchical Non-Equilibrium Systems Simulation package
Thomas Blommel, Jeremija Kovačević, Jason Kaye +3
We present H-NESSi (The Hierarchical Non-Equilibrium Systems Simulation package), an open-source software package for solving the Kadanoff-Baym equations (KBE) of nonequilibrium Gr…
Towards numerically exact computation of conductivity in the thermodynamic limit of interacting lattice models
Jeremija Kovačević, Michel Ferrero, Jakša Vučičević
Computing dynamical response functions in interacting lattice models is a long standing challenge in condensed matter physics. In view of recent results, the dc resistivity $ρ_\mat…
Simple predictors of in superconducting cuprates and the role of interactions between effective Wannier orbitals in the 3-band model
Jaksa Vucicevic, Michel Ferrero
At optimal doping, different cuprate compounds can exhibit vastly different critical temperatures for superconductivity (), ranging from about 20 K to about 135 K. The precise…
Charge fluctuations, hydrodynamics and transport in the square-lattice Hubbard model
J. Vucicevic, S. Predin, M. Ferrero
Recent experimental results suggest that a particular hydrodynamic theory describes charge fluctuations at long wavelengths in the square-lattice Hubbard model. Due to the continui…
Fermionic-propagator and alternating-basis quantum Monte Carlo methods for correlated electrons on a lattice
Veljko Janković, Jakša Vučičević
Ultracold-atom simulations of the Hubbard model provide insights into the character of charge and spin correlations in and out of equilibrium. The corresponding numerical simulatio…
Mott domain walls: a (strongly) non-Fermi liquid state of matter
Tsung-Han Lee, J. Vučičević, D. Tanasković +2
Most Mott systems display a low-temperature phase coexistence region around the metal-insulator transition. The domain walls separating the respective phases have very recently bee…
Universal magnetic oscillations of DC conductivity in the incoherent regime of correlated systems
Jaksa Vucicevic, Rok Zitko
Using the dynamical mean field theory we investigate the magnetic field dependence of DC conductivity in the Hubbard model on the square lattice, fully taking into account the orbi…
Electrical conductivity in the Hubbard model: orbital effects of magnetic field
Jaksa Vucicevic, Rok Zitko
Calculation of conductivity in the Hubbard model is a challenging task. Recent years have seen much progress in this respect and numerically exact solutions are now possible in cer…
Pfaffian paired states for half-integer fractional quantum Hall effect
M. V. Milovanovic, S. Djurdjevic, J. Vucicevic +1
In this review the physics of Pfaffian paired states, in the context of fractional quantum Hall effect, is discussed using field-theoretical approaches. The Pfaffian states are pri…
Analytical solution for time-integrals in diagrammatic expansions: application to real-frequency diagrammatic Monte Carlo
J. Vucicevic, P. Stipsic, M. Ferrero
The past years have seen a revived interest in the diagrammatic Monte Carlo (DiagMC) methods for interacting fermions on a lattice. A promising recent development allows one to now…
Charge transport in the Hubbard model at high temperatures: triangular versus square lattice
A. Vranic, J. Vucicevic, J. Kokalj +4
High-temperature bad-metal transport has been recently studied both theoretically and in experiments as one of the key signatures of strong electronic correlations. Here we use the…
Real-frequency Diagrammatic Monte Carlo at Finite Temperature
Jaksa Vucicevic, Michel Ferrero
Diagrammatic expansions are a central tool for treating correlated electron systems. At thermal equilibrium, they are most naturally defined within the Matsubara formalism. However…
Conductivity in the square lattice Hubbard model at high temperatures: importance of vertex corrections
Jaksa Vucicevic, Jure Kokalj, Rok Zitko +3
Recent experiments on cold atoms in optical lattices allow for a quantitative comparison of the measurements to the conductivity calculations in the square lattice Hubbard model. H…
Paired states at 5/2: PH Pfaffian and particle-hole symmetry breaking
L. Antonic, J. Vucicevic, M. V. Milovanovic
We study Cooper pairing in the Dirac composite fermion (CF) system. The presence of the mass term in the Dirac CF description (which may simulate Landau level mixing) i.e. breaking…
Practical consequences of Luttinger-Ward functional multivaluedness for cluster DMFT methods
Jaksa Vucicevic, Nils Wentzell, Michel Ferrero +1
The Luttinger-Ward functional (LWF) has been a starting point for conserving approximations in many-body physics for 50 years. The recent discoveries of its multivaluedness and the…
The Fierz convergence criterion: a controlled approach to strongly-interacting systems with small embedded clusters
Thomas Ayral, Jaksa Vucicevic, Olivier Parcollet
We present an embedded-cluster method, based on the TRILEX formalism. It turns the Fierz ambiguity, inherent to approaches based on a bosonic decoupling of local fermionic interact…
TRILEX and +EDMFT approach to -wave superconductivity in the Hubbard model
Jaksa Vucicevic, Thomas Ayral, Olivier Parcollet
We generalize the recently introduced TRILEX approach (TRiply Irreducible Local EXpansion) to superconducting phases. The method treats simultaneously Mott and spin-fluctuation phy…
Anderson localization effects near the Mott metal-insulator transition
Helena Braganca, M. C. O. Aguiar, J. Vucicevic +2
The interplay between Mott and Anderson routes to localization in disordered interacting systems gives rise to different transitions and transport regimes. Here, we investigate the…
