Coordination motifs and large-scale structural organization in atomic clusters
Zhu Yang, Lei-Han Tang
The structure of nanoclusters is complex to describe due to their noncrystallinity, even though bonding and packing constraints limit the local atomic arrangements to only a few ty…
Phase glass and zero-temperature phase transition in a randomly frustrated two-dimensional quantum rotor model
Lei-Han Tang, Qing-Hu Chen
The ground state of the quantum rotor model in two dimensions with random phase frustration is investigated. Extensive Monte Carlo simulations are performed on the corresponding (2…
Finite-size scaling of synchronized oscillation on complex networks
Hyunsuk Hong, Hyunggyu Park, Lei-Han Tang
The onset of synchronization in a system of random frequency oscillators coupled through a random network is investigated. Using a mean-field approximation, we characterize sample-…
Entrainment transition in populations of random frequency oscillators
Hyunsuk Hong, Hugues Chate, Hyunggyu Park +1
The entrainment transition of coupled random frequency oscillators is revisited. The Kuramoto model (global coupling) is shown to exhibit unusual sample-dependent finite size effec…
Anomalous Binder Cumulant and Lack of Self-Averageness in Systems with Quenched Disorder
Hyunsuk Hong, Hyunggyu Park, Lei-Han Tang
The Binder cumulant (BC) has been widely used for locating the phase transition point accurately in systems with thermal noise. In systems with quenched disorder, the BC may show s…
Ground state and glass transition of the RNA secondary structure
Sheng Hui, Lei-Han Tang
RNA molecules form a sequence-specific self-pairing pattern at low temperatures. We analyze this problem using a random pairing energy model as well as a random sequence model that…
