Quantum Nonlinear Sigma Model for Arbitrary Spin Heisenberg Antiferromagnets
Jianhui Dai, Wei-Min Zhang
In this Letter, we derive a quantum nonlinear sigma model (QNLSM) for quantum Heisenberg antiferromagnets (QHA) with arbitrary S (spin) values. A upper limit of the low temperature…
Entanglement and quantum phase transition in quantum mixed spin chains
Shang-Bin Li, Zhao-Xing Xu, Jian-Hui Dai +1
The ground entanglement and thermal entanglement in quantum mixed spin chains consisting of two integer spins 1 and two half integer spins 1/2 arrayed as in a uni…
Quantum Monte Carlo Simulations on S=1/2 antiferromagnetic-Ferromagnetic Random Alternating spin chain
Peng Zhang, Zhaoxin Xu, Heping Ying +1
The S=1/2 Heisenberg chain with bond alternation and randomness of antiferromagnetic (AFM) and ferromagnetic (FM) interactions is investigated by quantum Monte Carlo simulations of…
Two-Electron Linear Intersubband Light Absorption in a Biased Quantum Well
J. Dai, M. E. Raikh, T. V. Shahbazyan
We point out a novel manifestation of many-body correlations in the linear optical response of electrons confined in a quantum well. Namely, we demonstrate that along with conventi…
