Enhanced sensing of 3.4 GHz microwave in multi-level Rydberg atomic system
Xue Jingjing, Li Ruonan, Hu Xuesong +3
The Rydberg-based microwave detection is an all-optical technology that uses the strong coherent interaction between Rydberg atoms and microwave field. Different from the tradition…
Nature of the ferromagnetic-antiferromagnetic transition in YLaTiO
S. Hameed, S. El-Khatib, K. P. Olson +18
We explore the magnetically-ordered ground state of the isovalently-substituted Mott-insulator YLaTiO for 0.3 via single crystal growth, magnetometry…
Persistent Current in the Ferromagnetic Kondo Lattice Model
Jun Zang, S. A. Trugman, A. R. Bishop +1
In this paper, we study the zero temperature persistent current in a ferromagnetic Kondo lattice model in the strong coupling limit. In this model, there are spontaneous spin textu…
High Temperature Thermodynamics of the Ferromagnetic Kondo-Lattice Model
H. Roder, R. R. P. Singh, J. Zang
We present a high temperature series expansion for the ferromagnetic Kondo lattice model in the large coupling limit, which is used to model CMR perovskites. Our results show the e…
Interchain Coupling Effects and Solitons in CuGeO_3
Jun Zang, Sudip Chakravarty, A. R. Bishop
The effects of interchain coupling on solitons and soliton lattice structures in CuGeO3 are explored. It is shown that interchain coupling substantially increases the soliton width…
Charge Localization in Disordered Colossal-Magnetoresistance Manganites
Qiming Li, Jun Zang, A. R. Bishop +1
The metallic or insulating nature of the paramagnetic phase of the colossal-magnetoresistance manganites is investigated via a double exchange Hamiltonian with diagonal disorder. M…
Nonequilibrium transport and population inversion in double quantum dot systems
Jun Zang, Joseph L Birman, A. R. Bishop +1
We present a microscopic theory for both equilibrium and nonequilibrium transport properties of coupled double quantum dots (DQD). A general formula for current tunneling through t…
Low Temperature Magnetic Properties of the Double Exchange Model
Jun Zang, H. Röder, A. R. Bishop +1
We study the {\it ferromagnetic} (FM) Kondo lattice model in the strong coupling limit (double exchange (DE) model). The DE mechanism proposed by Zener to explain ferromagnetism ha…
Double Degeneracy and Jahn-Teller Effects in CMR Perovskites
Jun Zang, A. R. Bishop, H. Roder
Jahn-Teller (JT) electron-phonon coupling effects in the colossal magnetoresistance perovskite compounds are investigated. Electron-electron correlations between…
Frustrated Spin-Peierls Chains
Jun Zang, A. R. Bishop, D. Schmeltzer
We study the phase diagram, ground state properties, and excitation gaps of a frustrated spin-Peierls chain, i.e. a spin-Peierls chain with both nearest neighbor exchange and…
Structure of the Magneto-Exciton and Optical Properties in Fractional Quantum Hall Systems
Jun Zang, Joseph L Birman
We report calculated dependence of magneto-exciton energy spectrum upon electron-hole separation in Fractional Quantum Hall systems. We calculated the dependence of photolumine…
Theory of Second Order Optical Processes from A Luttinger Liquid
Jun Zang, Joseph L Birman, Zhao-Bin Su
We develop a theory for the total optical secondary emission from a 1D interacting electron system modelled as a Tomonaga-Luttinger liquid. We separate the emission into two parts…
