Activated dynamics in the quantum random field Ising model
Ivan Balog, Lovro Å aravanja, Andrei A. Fedorenko
We study the critical dynamics of the quantum random-field Ising model using the nonperturbative functional renormalization group (NP-FRG). The static critical behavior is found to…
Boundary critical behavior of the Gross-Neveu-Yukawa model
Andrei A. Fedorenko, Ilya A. Gruzberg
We study the critical behavior of the semi-infinite Gross-Neveu-Yukawa model, a quantum field theory describing Dirac fermions interacting with bosonic fields via a Yukawa coupling…
The stochastic porous medium equation in one dimension
Maximilien Bernard, Andrei A. Fedorenko, Pierre Le Doussal +1
We study the porous medium equation (PME) in one space dimension in presence of additive non-conservative white noise, and interpreted as a stochastic growth equation for the heigh…
Mott-glass phase induced by long-range correlated disorder in a one-dimensional Bose gas
Nicolas Dupuis, Andrei A. Fedorenko
We determine the phase diagram of a one-dimensional Bose gas in the presence of disorder with short- and long-range correlations, the latter decaying with distance as $1/|x|^{1+Ï}…
