Finite-size scaling and dynamics in a two-dimensional lattice of identical oscillators with frustrated couplings
Róbert Juhász, Géza Ódor
A two-dimensional lattice of oscillators with identical (zero) intrinsic frequencies and Kuramoto type of interactions with randomly frustrated couplings is considered. Starting th…
Renormalization theory of disordered contact processes with heavy-tailed dispersal
Róbert Juhász
Motivated by long-range dispersal in ecological systems, we formulate and apply a general strong-disorder renormalization group (SDRG) framework to describe one-dimensional disorde…
Exact bounds on the energy gap of transverse-field Ising chains by mapping to random walks
Róbert Juhász
Based on a relationship with continuous-time random walks discovered by Iglói, Turban, and Rieger [Phys. Rev. E {\bf 59}, 1465 (1999)], we derive exact lower and upper bounds on th…
Testing the validity of random-singlet state for long-range hopping models through the scaling of entanglement entropy
Róbert Juhász
We consider a sublattice-symmetric free-fermion model on a one-dimensional lattice with random hopping amplitudes decaying with the distance as , and address the…
Random transverse-field Ising chain with long-range interactions
Róbert Juhász, István A. Kovács, Ferenc Iglói
We study the low-energy properties of the long-range random transverse-field Ising chain with ferromagnetic interactions decaying as a power alpha of the distance. Using variants o…
