Spin Nernst effect and spatiotemporal dynamic simulation of topological magnons in the antiferromagnet Cu3TeO6

The topological surface state arising from the nontrivial topology of the bulk band structure has attracted a wide range of interest. Compared with electrons, the magnon propagation in magnetic materials can be more intuitively reflected in the spin precession and generate different effects. Using molecular dynamics simulations, we ... Phys.

Harvesting Energy from Changes in Relative Humidity Using Nanoscale Water Capillary Bridges

We show that nanoscale water capillary bridges (WCB) formed between patchy surfaces can extract energy from the environment when subjected to changes in relative humidity (RH). Our results are based on molecular dynamics simulations combined with a modified version of the Laplace-Kelvin equation, which is validated using the nanoscale WCB... Langmuir 2023, XXXX, XXX, XXX-XXX  PDF Download 

Topology of vibrational modes predict plastic events in glasses

The plastic deformation of crystalline materials can be understood by considering their structural defects such as disclinations and dislocations. Although also glasses are solids, their structure resembles closely the one of a liquid and hence the concept of structural defects becomes ill-defined...  Nature Communications (2023) 14:2955  PDF Download  Pkuphyers news  Nat.

Quantum criticality of a Z3 symmetric spin chain with long-range interactions

Based on large-scale density matrix renormalization group techniques, we investigate the critical behaviors of quantum three-state Potts chains with long-range interactions. Using fidelity susceptibility as an indicator, we obtain a complete phase diagram of the system. The results show that as the long-range interaction power 𝛼 increases...  Phys. Rev.
