Interfacial thermal resistance (ITR) is the main obstacle for heat flows from one material to
another. Understanding ITR becomes essential for the removal of redundant heat from fast …

Significant progress has been made in the past two decades about the micro/nanoscale
heat conduction. Many computational methods have been developed to accommodate the …

We extend the theory of dipole moments in crystalline insulators to higher multipole
moments. As first formulated in Benalcazar et al.[Science 357, 61 (2017) SCIEAS 0036-8075 …

Thermal transport properties of amorphous materials are crucial for their emerging
applications in energy and electronic devices. However, understanding and controlling …

The heat dissipation issue has now become one of the most important bottlenecks for power
electronics due to the rapid increase in power density and working frequency. Towards the …

A topological electric quadrupole is a recently proposed concept that extends the theory of
electric polarization of crystals to higher orders. Such a quadrupole phase supports …

We provide the bulk topological invariant for chiral higher-order topological insulators in (i)
fourfold rotoinversion invariant bulk crystals, and (ii) inversion-symmetric systems with or …

In this Rapid Communication we predict several types of topological semimetals that exhibit
a bulk quadrupole moment. These semimetals are modeled with a three-dimensional …

Atomistic simulation methods, including anharmonic lattice dynamics combined with the
Boltzmann transport equation, equilibrium and non-equilibrium molecular dynamics …

The Su-Schrieffer-Heeger (SSH) model on a two-dimensional square lattice exhibits a
topological phase transition which is related to the Zak phase determined by bulk band …
