Memory effect and phase transition in a hierarchical trap model for spin glass
Depei Zhang, Tianran Chen, Marija Vucelja +2
We introduce an efficient dynamical tree method that enables us, for the first time, to explicitly demonstrate thermo-remanent magnetization memory effect in a hierarchical energy…
Aging, memory, and nonhierarchical energy landscape of spin jam
Anjana Samarakoon, Taku J. Sato, Tianran Chen +5
The notion of complex energy landscape underpins the intriguing dynamical behaviors in many complex systems ranging from polymers, to brain activity, to social networks and glass t…
Enhancement of hopping conductivity by spontaneous fractal ordering of low-energy sites
Tianran Chen, Brian Skinner
Variable-range hopping conductivity has long been understood in terms of a canonical prescription for relating the single-particle density of states to the temperature-dependent co…
Coulomb gap triptychs, effective charge, and hopping transport in periodic arrays of superconductor grains
Tianran Chen, Brian Skinner, B. I. Shklovskii
In granular superconductors, individual grains can contain bound Cooper pairs while the system as a whole is strongly insulating. In such cases the conductivity is determined by el…
