Dynamical quantum phase transitions in a spin chain with deconfined quantum critical points
Gaoyong Sun, Bo-Bo Wei
We analytically and numerically study the Loschmidt echo and the dynamical order parameters in a spin chain with a deconfined phase transition between a dimerized state and a ferro…
Fidelity Susceptibility in One-dimensional Disordered Lattice Models
Bo-Bo Wei
We investigate quantum phase transitions in one-dimensional quantum disordered lattice models, the Anderson model and the Aubry-André model, from the fidelity susceptibility approa…
Dissipation in the Generalized Gibbs Ensemble
Bo-Bo Wei
In this work, we show that the dissipation in a many-body system under an arbitrary non-equilibrium process is related to the Rényi divergences between two states along the forward…
Quantum Work Relations and Response Theory in -Symmetric Quantum Systems
Bo-Bo Wei
In this work, we show that a universal quantum work relation for a quantum system driven arbitrarily far from equilibrium extend to -symmetric quantum system with unb…
Links between Dissipation and Rényi Divergences in -Symmetric Quantum Mechanics
Bo-Bo Wei
Thermodynamics and information theory have been intimately related since the times of Maxwell and Boltzmann. Recently it was shown that the dissipated work in an arbitrary non-equi…
Probing Conformal Invariant of Non-unitary Two-Dimensional Systems by Central Spin Decoherence
Bo-Bo Wei
Universality classes of non-unitary critical theories in two-dimensions are characterized by a dimensional number, termed central charge or conformal anomaly. Conformal invariance…
Probing Yang-Lee Edge Singularity by Central Spin Decoherence
Bo-Bo Wei
Yang-Lee edge singularities are the branch point of the free energy on the complex plane of physical parameters and were shown to be the simplest universality class of phase transi…
Insights into Phase Transitions and Entanglement from Density Functional Theory
Bo-Bo Wei
Density functional theory has made great success in solid state physics, quantum chemistry and in computational material sciences. In this work we show that density functional theo…
Relations between Dissipated Work and Rényi Divergences
Bo-Bo Wei, M. B. Plenio
In this paper, we establish a general relation which directly links the dissipated work done on a system driven arbitrarily far from equilibrium, a fundamental quantity in thermody…
Phase transitions in the complex plane of physical parameters
Bo-Bo Wei, Shao-Wen Chen, Hoi-Chun Po +1
At low temperature a thermodynamic system undergoes a phase transition when a physical parameter passes through a singularity point of the free energy, corresponding to formation o…
Solvable Lattice Gas Models with Three Phases
B. B. Wei, C. N. Yang
Phase boundaries in p-T and p-V diagrams are essential in material science researches. Exact analytic knowledge about such phase boundaries are known so far only in two-dimensional…
Probing Lee-Yang zeros and coherence sudden death
Bo-Bo Wei, Ren-Bao Liu
As a foundation of statistical physics, Lee and Yang in 1952 proved that the partition functions of thermal systems can be zero at certain points (called Lee-Yang zeros) on the com…
Pair Distribution Function of One-dimensional "Hard Sphere" Fermi and Bose Systems
Bo-Bo Wei, Chen-Ning Yang
The pair distributions of one-dimensional "hard sphere" fermion and boson systems are exactly evaluated by introducing gap variables.
Ground state properties of a Tonks-Girardeau Gas in a periodic potential
Bo-Bo Wei, Shi-Jian Gu, Hai-Qing Lin
In this paper, we investigate the ground-state properties of a bosonic Tonks-Girardeau gas confined in a one-dimensional periodic potential. The single-particle reduced density mat…
Exact results of two-component Fermi gas in a hard wall trap
Bo-Bo Wei, Jun-Peng Cao, Shi-Jian Gu +1
We investigate the ground state properties of a one-dimensional two-component ultra-cold Fermi gas in an infinite potential well. Exact Bethe ansatz solution is used to calculate t…
