A Spectral Route to Directed-Polymer Glasses
Sen Mu, Abbas Ali Saberi, Mehran Kardar
A finite density of mutually avoiding directed polymers in a quenched random medium is a minimal model of glassy line matter. The dilute theory, solved by replica Bethe ansatz, pre…
Enhanced Density Fluctuations Near a Disordered Chiral Topological Transition
Hai-Tao Ding, Sen Mu, Leong-Chuan Kwek +2
The universal statistics of density fluctuations of localized quantum states may offer unprecedented opportunities to probe and understand quantum transport in connection with dime…
Boundary Floquet Control of Bulk non-Hermitian Systems
Yu-Min Hu, Yu-Bo Shi, Linhu Li +5
Boundary perturbations are generally irrelevant for bulk properties in the thermodynamic limit, as they are edge-confined and subextensive. We show that this expectation breaks dow…
Directed Polymer Transfer Matrices as a Unified Generator of Distinct One-Point Fluctuation Laws
Sen Mu, Abbas Ali Saberi, Roderich Moessner +1
We numerically revisit the transfer-matrix formulation of directed polymers in random media and show that a common finite-dimensional framework organizes the canonical one-point fl…
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…
Kardar-Parisi-Zhang and glassy properties in 2D Anderson localization: eigenstates and wave packets
Noam Izem, Bertrand Georgeot, Jiangbin Gong +2
Despite decades of research, the universal nature of fluctuations in disordered quantum systems remains poorly understood. Here, we present extensive numerical evidence that fluctu…
