Heitler effect and resonance fluorescence in quantum magnonics

Posted by klaurent Delft

Kavli Affiliate: Ya Blanter | Summary:We consider a coupled system of a qubit and a magnon mode in which the qubit is weakly driven. We demonstrate that the spectral steady-state responses of both the qubit and the magnon show, in addition to two sidebands split by the coupling, also a peak at the driving frequency […]

Nearsightedness in Materials with Indirect Band Gaps

Kavli Affiliate: Hsiaowen Chen| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We investigate the nearsightedness property in the linear tight binding model at zero Fermi-temperature. We focus on the decay property of the density matrix for materials with indirect band gaps. By representing the density matrix in reciprocal space, we establish a qualitatively sharp […]
