We study the thermal transport through a quantum spin-1/2 chain heterostructure, which consists of a finite-size chain with two-site isotropic XY interaction and three-site XZX+YZY interaction coupled at its ends to two semi-infinite isotropic XY chains. After performing Jordan-Wigner transformation, we map the original spin Hamiltonian into a fermion Hamiltonian and express the heat current with a nonequilibrium Green’s function formalism. Then, the heat current as functions of the structure parameters are studied in detail. As a result, we observe that a finite magnetic field applied at the finite-size chain can efficiently induce the heat current asymmetry with ΔΩ (ΔΩ is the magnetic field difference between the finite-size chain and the semi-infinite chains). Accordingly, such a magnetic field can be viewed as a switch in manipulating the heat current.read more

Structural phase transitions in two-dimensional Mo- and W-dichalcogenide monolayers.
TL;DR: This work discovers that mechanical deformations provide a route to switching thermodynamic stability between a semiconducting and a metallic crystal structure in these monolayer materials and finds that MoTe2 is an excellent candidate phase change material.

Universal scaling for the dilemma strength in evolutionary games.
TL;DR: In this paper, the authors proposed new universal scaling parameters for the dilemma strength, and proved universality by showing that the conditions for an ESS and the expressions for the internal equilibriums in an infinite, well-mixed population subjected to any of the five reciprocity mechanisms depend only on the new scaling parameters.

Opportunities for mesoscopics in thermometry and refrigeration: Physics and applications
TL;DR: In this paper, a review of the thermal properties of mesoscopic structures is presented based on the concept of electron energy distribution, and, in particular, on controlling and probing it, and an immediate application of solidstate refrigeration and thermometry is in ultrasensitive radiation detection, which is discussed in depth.

Thermal diode: rectification of heat flux.
TL;DR: By coupling two nonlinear one dimensional lattices, this work provides numerical and analytical evidence for the underlying mechanism which allows heat flux in one direction while the system acts like an insulator when the temperature gradient is reversed.

Solid state thermal rectifier
TL;DR: In this paper, a high mass density material is added preferentially to one end of the nanostructures to produce an axially non-uniform mass distribution, and the resulting nanoscale system conducts heat asymmetrically with greatest heat flow in the direction of decreasing mass density.

Thermal Logic Gates: Computation with Phonons
TL;DR: This work builds up thermal logic gates that can perform similar operations as their electronic counterparts, and demonstrates that phonons, the heat carriers, can also be used to carry information and processed accordingly.

Controlling the Energy Flow in Nonlinear Lattices: A Model for a Thermal Rectifier
TL;DR: In this paper, the authors address the problem of heat conduction in 1D nonlinear chains and show that, acting on the parameter which controls the strength of the on-site potential inside a segment of the chain, they induce a transition from conducting to insulating behavior in the whole system.
