Quantum Fisher information as signature of superradiant quantum phase transition
T. L. Wang, L. N. Wu, W. Yang +3
The single-mode Dicke model is well-known to undergo a quantum phase transition from the so-called normal phase to the supperradiant phase (hereinafter called the "superradiant qua…
Probing zero-modes of defect in Kitaev quantum wire
Sheng-Wen Li, Zeng-Zhao Li, C. Y. Cai +1
The Kitaev quantum wire (KQW) model with open boundary possesses two Majorana edge modes. When the local chemical potential on a defect site is much higher than that on other sites…

Analog quantum simulators can be used to study quantum correlation in novel many-body systems by emulating the Hamiltonian of these systems. One essential question in quantum simul…
Room-temperature ultra-sensitive mass spectrometer via dynamic decoupling
Nan Zhao, Zhang-qi Yin
We propose an ultra-sensitive mass spectrometer based on a coupled quantum-bit-oscillator system. Under dynamical decoupling control of the quantum bit (qubit), the qubit coherence…
Canonical versus noncanonical equilibration dynamics of open quantum systems
