Maximal Entanglement and Frozen Information: A Unified Framework for Dynamical Quantum Phase Transitions
Kaiyuan Cao, Mingzhi Li, Xiang-Ping Jiang +2
Dynamical quantum phase transitions (DQPTs) are temporal singularities marked by zeros of the Loschmidt echo, yet their underlying quantum-information structure remains elusive. He…
Tailoring Dynamical Quantum Phase Transitions via Double-Mode Squeezing Manipulation
Kaiyuan Cao, Haodong Wang, Xiang-Ping Jiang +2
We propose a protocol to tailor dynamical quantum phase transitions (DQPTs) by double-mode squeezing onto the initial state in the XY chain. The effect of squeezing depends critica…
Hierarchy of localized many-body bound states in an interacting open lattice
Yanxia Liu, Shu Chen
We unveil the mechanism for the formation of puzzled boundary-localized bound states in a spinless fermionic open lattice with nearest-neighbor interactions. By solving the Bethe-a…
Digital Quantum Simulation of the Lindblad Master Equation and Its Nonlinear Extensions via Quantum Trajectory Averaging
Yu-Guo Liu, Heng Fan, Shu Chen
Since precisely controlling dissipation in realistic environments is challenging, digital simulation of the Lindblad master equation (LME) is of great significance for understandin…
Relation between equilibrium quantum phase transitions and dynamical quantum phase transitions in two-band systems
Yumeng Zeng, Shu Chen
The dynamical quantum phase transition (DQPT) is an important concept in nonequilibrium critical phenomena; however, its relation to the equilibrium quantum phase transition (EQPT)…
Topological State Transfer through Effective Boundary-Mode Channels
Chong Wang, Xiu Gu, Shu Chen +1
Localized edge modes provide a compact channel for transferring an excitation through an extended lattice, but the relation between the microscopic chain and the few levels that ac…
Landauer-type transport theory for interacting quantum wires: Application to carbon nanotube Y junctions
S. Chen, B. Trauzettel, R. Egger
We propose a Landauer-like theory for nonlinear transport in networks of one-dimensional interacting quantum wires (Luttinger liquids). A concrete example of current experimental f…
