Experimental realization of the complete seven-phase Anderson-localization landscape
Yao Qin, Chao Yang, Yuzhe Zhang +2
Anderson localization has evolved far beyond the conventional dichotomy between extended and localized states. Modern localization theory predicts a complete transport hierarchy co…
Controlling Liouvillian topological phases via Hamiltonian band topology under chiral symmetry
Shu Long, Hong-Sen Yin, Chao Yang +3
We establish a direct connection between Hamiltonian band topology and the Liouvillian spectral winding of open quantum systems with quadratic dissipations. This allows the band to…
Extended Landauer-Büttiker Formula for Current through Open Quantum Systems with Gain or Loss
Chao Yang, Yucheng Wang
The Landauer-Büttiker formula, which characterizes the current flowing through a finite region connected to leads, has significantly advanced our understanding of transport. We ex…
Dissipation-Driven Transition of Particles from Dispersive to Flat Bands
Yutao Hu, Chao Yang, Yucheng Wang
Flat bands (FBs) play a crucial role in condensed matter physics, offering an ideal platform to study strong correlation effects and enabling applications in diffraction-free photo…
Dissipation-induced Half Quantized Conductance in One-dimensional Topological Systems
Bozhen Zhou, Pan Zhang, Yucheng Wang +1
Quantized conductance from topologically protected edge states is a hallmark of two-dimensional topological phases. In contrast, edge states in one-dimensional (1D) topological sys…
Inducing a transition between thermal and many-body localized states and detecting many-body mobility edges through dissipation
Yutao Hu, Chao Yang, Yucheng Wang
The many-body mobility edge (MBME) in energy, which separates thermal states from many-body localization (MBL) states, is a critical yet controversial concept in MBL physics. Here…
