Commensurate-Incommensurate Transitions of the 1D Disordered Chiral Clock Model
Pengfei Liang, Rosario Fazio, Stefano Chesi
We study the effects of quenched disorder on the commensurate-incommensurate transitions in the 1D chiral clock model. The interplay of domain walls and rare regions…
Time Crystals in the Driven Transverse Field Ising Model under Quasiperiodic Modulation
Pengfei Liang, Rosario Fazio, Stefano Chesi
We investigate the transverse field Ising model subject to a two-step periodic driving protocol and quasiperiodic modulation of the Ising couplings. Analytical results on the phase…
Condensed Matter Physics in Time Crystals
Lingzhen Guo, Pengfei Liang
Time crystals are physical systems whose time translation symmetry is spontaneously broken. Although the spontaneous breaking of continuous time-translation symmetry in static syst…
Scalable Ion Trap Architecture for Universal Quantum Computation by Collisions
Pengfei Liang, Lingzhen Guo
We propose a scalable ion trap architecture for universal quantum computation, which is composed of an array of ion traps with one ion confined in each trap. The neighboring traps…
Floquet Many-body Engineering: Topological and Many-body Physics in Phase Space Lattices
Pengfei Liang, Michael Marthaler, Lingzhen Guo
Hamiltonians which are inaccessible in static systems can be engineered in periodically driven many-body systems, i.e., Floquet many-body systems. We propose to use interacting par…
Exact quantum Bayesian rule for qubit measurements in circuit QED
Wei Feng, Pengfei Liang, Lupei Qin +1
Developing efficient framework for quantum measurements is of essential importance to quantum science and technology. In this work, for the important superconducting circuit-QED se…
