Berry phases for composite fermions: effective magnetic field and fractional statistics
Gun Sang Jeon, Kenneth L. Graham, Jainendra K. Jain
The quantum Hall superfluid is presently the only viable candidate for a realization of quasiparticles with fractional Berry phase statistics. For a simple vortex excitation, relev…
Composite fermion theory of correlated electrons in semiconductor quantum dots in high magnetic fields
Gun Sang Jeon, Chia-Chen Chang, Jainendra K. Jain
Interacting electrons in a semiconductor quantum dot at strong magnetic fields exhibit a rich set of states, including correlated quantum fluids and crystallites of various symmetr…
XY model in small-world networks
Beom Jun Kim, H. Hong, Petter Holme +3
The phase transition in the XY model on one-dimensional small-world networks is investigated by means of Monte-Carlo simulations. It is found that long-range order is present at fi…
Double stochastic resonance peaks in systems with dynamic phase transitions
Beom Jun Kim, Petter Minnhagen, Hyun Jin Kim +2
To probe the connection between the dynamic phase transition and stochastic resonance, we study the mean-field kinetic Ising model and the two-dimensional Josephson-junction array…
Spatiotemporal Stochastic Resonance in Fully Frustrated Josephson Ladders
Beom Jun Kim, Mahn-Soo Choi, Petter Minnhagen +3
We consider a Josephson-junction ladder in an external magnetic field with half flux quantum per plaquette. When driven by external currents, periodic in time and staggered in spac…
Quantum phase transitions in superconducting arrays under external magnetic fields
Beom Jun Kim, Gun Sang Jeon, M. -S. Choi +1
We study the zero-temperature phase transitions of two-dimensional superconducting arrays with both the self- and the junction capacitances in the presence of external magnetic fie…
