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…
Universal fluctuations of localized two interacting particles in one dimension
Sen Mu, Gabriel Lemarié, Jiangbin Gong
We investigate the universal fluctuations of localized wavefunction in the Fock space of two interacting particles in one-dimensional disordered systems, focusing on the interplay…
Kardar-Parisi-Zhang Physics in the Density Fluctuations of Localized Two-Dimensional Wave Packets
Sen Mu, Jiangbin Gong, Gabriel Lemarié
We identify the key features of Kardar-Parisi-Zhang universality class in the fluctuations of the wave density logarithm, in a two-dimensional Anderson localized wave packet. In ou…
Superfluidity vs prethermalisation in a nonlinear Floquet system
Sen Mu, Nicolas Macé, Jiangbin Gong +3
We show that superfluidity can be used to prevent thermalisation in a nonlinear Floquet system. Generically, periodic driving boils an interacting system to a featureless infinite…
Direction reversal of non-Hermitian skin effect via coherent coupling
Linhu Li, Wei Xin Teo, Sen Mu +1
Absolute negative mobility (ANM) in nonequilibrium systems depicts the possibility of particles propagating toward the opposite direction of an external force. We uncover in this w…
Anomalous hybridization of spectral winding topology in quantized steady-state responses
Hui-Qiang Liang, Sen Mu, Jiangbin Gong +1
Quantized response is one distinguishing feature of a topological system. In non-Hermitian systems, the spectral winding topology yields quantized steady-state response. By conside…
Non-Hermitian pseudo mobility edge in a coupled chain system
Sen Mu, Longwen Zhou, Linhu Li +1
In this work, we explore interesting consequences arising from the coupling between a clean non-Hermitian chain with skin localization and a delocalized chain of the same length un…
Prethermalization and wave condensation in a nonlinear disordered Floquet system
Prosenjit Haldar, Sen Mu, Bertrand Georgeot +3
Periodically-driven quantum systems make it possible to reach stationary states with new emerging properties. However, this process is notoriously difficult in the presence of inte…
Quantized classical response from spectral winding topology
Linhu Li, Sen Mu, Ching Hua Lee +1
Topologically quantized response is one of the focal points of contemporary condensed matter physics. While it directly results in quantized response coefficients in quantum system…
Topological and dynamical features of periodically driven spin ladders
Raditya Weda Bomantara, Sen Mu, Jiangbin Gong
Studies of periodically driven one-dimensional many-body systems have advanced our understanding of complex systems and stimulated promising developments in quantum simulation. It…
Critical non-Hermitian Skin Effect
Linhu Li, Ching Hua Lee, Sen Mu +1
This work uncovers a new class of criticality where eigenenergies and eigenstates of non-Hermitian lattice systems jump discontinuously across a critical point in the thermodynamic…
Emergent Fermi surface in a many-body non-Hermitian Fermionic chain
Sen Mu, Ching Hua Lee, Linhu Li +1
Quantum degeneracy pressure (QDP) underscores the stability of matter and is arguably the most ubiquitous many-body effect. The associated Fermi surface (FS) has broad implications…
Revealing many-body effects on interband coherence through adiabatic charge pumping
Sen Mu, Da-Jian Zhang, Longwen Zhou +1
The adiabatic charge pumping of a non-equilibrium state of spinless fermions in a one-dimensional lattice is investigated, with an emphasis placed on its usefulness in revealing ma…
