Biorthogonal-only Floquet Dynamical Quantum Phase Transitions
Jiangrong Wen, Qidong Yuan, Zi-Xiang Hu +1
Non-Hermitian dynamical quantum phase transitions (DQPTs) are intrinsically sensitive to the choice of inner product under nonunitary time evolution. Although the biorthogonal form…
Biorthogonal Dynamical Quantum Phase Transitions in Non-Hermitian Systems
Yecheng Jing, Jian-Jun Dong, Yu-Yu Zhang +1
By utilizing biorthogonal bases, we develop a comprehensive framework for studying biorthogonal dynamical quantum phase transitions in non-Hermitian systems. With the help of the p…
Superconducting fluctuations and charge-4 plaquette state at strong coupling
Qiong Qin, Jian-Jun Dong, Yutao Sheng +2
We apply the static auxiliary field Monte Carlo approach to study phase correlations of the pairing fields in a microscopic model with spin-singlet pairing interaction. We find tha…
Development of long-range phase coherence on the Kondo lattice
Jian-Jun Dong, Yi-feng Yang
Despite of many efforts, we still lack a clear picture on how heavy electrons emerge and develop on the Kondo lattice. Here we introduce a key concept named the hybridization bond…
Mutual information, quantum phase transition, and phase coherence in Kondo systems
Jian-Jun Dong, Dongchen Huang, Yi-feng Yang
We propose a static auxiliary field approximation to study the hybridization physics of Kondo systems without the sign problem and use the mutual information to measure the intersi…
Hybridization fluctuations in the half-filled periodic Anderson model
Danqing Hu, Jian-Jun Dong, Yi-feng Yang
Motivated by recent photoemission and pump-probe experiments, we report determinant Quantum Monte Carlo simulations of hybridization fluctuations in the half-filled periodic Anders…
Functional field integral approach to quantum work
Jian-Jun Dong, Yi-feng Yang
We introduce the functional field integral approach to study the statistics of quantum work under nonequilibrium conditions and derive the general formalism for a bilinear Hamilton…
Rigorous proof for the non-local correlation functions in the antiferromagnetic seamed transverse Ising ring
Jian-Jun Dong, Zhen-Yu Zheng, Peng Li
An unusual correlation function is conjectured by M. Campostrini et al. (Phys. Rev. E 91, 042123 (2015)) for the ground state of a transverse Ising chain with geometrical frustrati…
The A-Cycle Problem In XY model with Ring Frustration
Jian-Jun Dong, Peng Li
Traditionally, the transverse spin-1/2 XY model is mapped to a fermionic "c-cycle" problem, where the prior periodic boundary condition is applied to the fermionic chain and the ad…
The A-Cycle Problem for Transverse Ising Ring
Jian-Jun Dong, Peng Li, Qi-Hui Chen
Traditionally, the transverse Ising model is mapped to the fermionic c-cycle problem, which neglects the boundary effect due to thermodynamic limit. If persisting on a perfect peri…
Frustration-Induced Gaplessness in the Frustrated Transverse Ising Ring
Jian-Jun Dong, Peng Li, Qi-Hui Chen
New effects in the frustrated transverse Ising ring are predicted. The system is solved based on a mapping of Pauli spin operators to the Jordan-Wigner fermions. We group the low-l…
Applications of density matrix in the fractional quantum mechanics
Jianping Dong
The many-body space fractional quantum system is studied using the density matrix method. We give the new results of the Thomas-Fermi model, and obtain the quantum pressure of the…
