Fast binomial-code holonomic quantum computation with ultrastrong light-matter coupling
Ye-Hong Chen, Wei Qin, Roberto Stassi +2
We propose a protocol for bosonic binomial-code nonadiabatic holonomic quantum computation in a system composed of an artificial atom ultrastrongly coupled to a cavity resonator. I…
Chiral topological superconducting state with Chern number in PbBi/Ge(111)
Shuwen Sun, Wei Qin, Leiqiang Li +1
Materials realization of chiral topological superconductivity is a crucial condition for observing and manipulating Majorana fermions in condensed matter physics. Here we develop a…
Two-level systems with periodic -step driving fields: Exact dynamics and quantum state manipulations
Zhi-Cheng Shi, Ye-Hong Chen, Wei Qin +4
In this work, we derive exact solutions of a dynamical equation, which can represent all two-level Hermitian systems driven by periodic -step driving fields. For different physi…
Mirror Symmetry Breaking and Lateral Stacking Shifts in Twisted Trilayer Graphene
Chao Lei, Lukas Linhart, Wei Qin +2
We construct a continuum model of twisted trilayer graphene using {\it ab initio} density-functional-theory calculations, and apply it to address twisted trilayer electronic struct…
Butterfly-like anisotropic magnetoresistance and angle-dependent Berry phase in Type-II Weyl semimetal WP2
Kaixuan Zhang, Yongping Du, Pengdong Wang +12
Weyl semimetal emerges as a new topologically nontrivial phase of matter, hosting low-energy excitations of massless Weyl fermions. Here, we present a comprehensive study of the ty…
Tunable optomechanically induced transparency by controlling the dark-mode effect
Deng-Gao Lai, Xin Wang, Wei Qin +3
We study tunable optomechanically induced transparency by controlling the dark-mode effect induced by two mechanical modes coupled to a common cavity field. This is realized by int…
Shortcuts to Adiabaticity for the Quantum Rabi Model: Efficient Generation of Giant Entangled cat States via Parametric Amplification
Ye-Hong Chen, Wei Qin, Xin Wang +2
We propose a method for the fast generation of nonclassical ground states of the Rabi model in the ultrastrong and deep-strong coupling regimes via the shortcuts-to-adiabatic (STA)…
