Dynamical Poles in Non-Hermitian Impurity Scattering
Ao Yang, Kai Zhang, Chen Fang·Apr 14, 2026
In Hermitian impurity scattering, each isolated late-time exponential is the fingerprint of a bound state. We show that this correspondence breaks down in non-Hermitian bands. For a single impurity in a non-Hermitian lattice, the late-time signal is ...
Decoherence Resilience of the Non-Hermitian Skin Effect
Kunkun Wang, Lei Xiao, Stefano Longhi +1 more·Apr 14, 2026
Decoherence and dissipation, arising from unavoidable interactions with the environment, can exert a dual influence on transport in physical systems, suppressing coherent propagation while inducing diffusion and mitigating localization in disordered ...
$\mathbb{Z}_{2}$ Skin Channels and Scale-Dependent Dynamical Quantum Phase Transitions
Yongxu Fu·Apr 14, 2026
We analytically describe the dynamically separated $\mathbb{Z}_{2}$ skin channels (wavepacket evolutions) under periodic boundary condition (PBC) in non-Hermitian systems with anomalous time-reversal symmetry (ATRS), by combining the semiclassical wo...
Chiral state conversion near an exceptional point: speed-noise competition
Qing-Wei Wang·Apr 14, 2026
One intriguing property of non-Hermitian systems is the breakdown of adiabatic theorem and chiral state conversion as the system dynamically encircles exceptional points. However, the subtle dependence of the chiral dynamics on the loop geometry, the...
Noise-Enhanced Self-Healing Dynamics in Non-Hermitian Systems
Wuping Yang, H. Huang·Apr 14, 2026
Self-healing is the ability of a wave packet to spontaneously restore its spatial profile after scattering. As an emergent feature of non-unitary dynamics, it has attracted significant interest in non-Hermitian physics. Here, we systematically invest...
The Quantum Kicked Rotor: A Paradigm of Quantum Chaos. Foundational aspects and new perspectives
Giuliano Benenti, Giulio Casati, Jiangbin Gong +1 more·Apr 14, 2026
The kicked rotor provides a simple yet powerful model for introducing many of the central concepts of classical and quantum chaos. Despite its apparent simplicity, it exhibits rich dynamical behavior and has found applications across a wide range of ...
Quantum chaotic systems: a random-matrix approach
Mario Kieburg·Apr 13, 2026
We review the ideas of how random matrix theory has to be properly applied to quantum physics; particularly we focus on how the spectrum has to be properly prepared and the random matrix correctly identified before the random matrix and the physical ...
Observation of feedback-directed quantum dynamics in large-scale quantum processors
Ruizhe Shen, Ching Hua Lee·Apr 13, 2026
Programmable quantum hardware provides an emerging platform for exploring and controlling non-unitary quantum dynamics through measurement-based operations. In this work, we introduce feedback-directed circuit architectures that integrate spatially s...
Noise-Induced Resurrection of Dynamical Skin Effects in Quasiperiodic Non-Hermitian Systems
Wuping Yang, H. Huang·Apr 13, 2026
The non-Hermitian skin effect (NHSE) refers to the accumulation of an extensive number of eigenstates at system boundaries under open boundary conditions (OBCs). As a dynamical consequence, wave packets in such systems drift and ultimately accumulate...
Quantum geometry of the non-Hermitian skin effect
Ken-Ichiro Imura, Kohei Kawabata·Apr 11, 2026
The non-Hermitian skin effect is nonreciprocity-induced localization phenomena in which a macroscopic number of eigenstates accumulate anomalously at the boundary, accompanied by the extreme sensitivity to boundary conditions. Here, we develop a geom...
Informational Mpemba Effect for Fast State Purification in Non-Hermitian System
C. G. Feyisa, Huan-YuKu, J. -S. You +1 more·Apr 9, 2026
Quantum systems are inherently fragile to environmental fluctuations or decoherence, limiting their advantages in applications of quantum information and quantum computation. State purification offers a route to recover the purity of system under noi...
Dissipative Hamilton Jacobi Dynamics and the Emergence of Quantum Wave Mechanics
Naleli Jubert Matjelo·Apr 7, 2026
We develop a dissipative extension of classical mechanics based on a complex, and more generally quaternionic, action principle that endows every classical system with an intrinsic environment. Decomposing the action into conservative and divergence-...
Exact WKB analysis of inverted triple-well: resonance, PT-symmetry breaking, and resurgence
Syo Kamata, Tatsuhiro Misumi, Cihan Pazarbaşı +1 more·Apr 7, 2026
We study non-Hermitian quantum mechanics of an inverted triple-well potential within the exact WKB framework. For a single classical potential, different Siegert boundary conditions define three distinct quantum problems: the PT-symmetric, resonance,...
Theory of the Collective Many-body Subradiance in Waveguide QED
Xin Wang, Junjun He, Zeyang Liao·Apr 5, 2026
We present an analytical theory for the most subradiant modes in a finite one-dimensional emitter array coupled to either an ideal or a nonideal waveguide. Using an effective non-Hermitian Hamiltonian together with a Bragg-edge open-boundary ansatz, ...
From Liouville equation to universal quantum control: A study of generating ultra highly squeezed states
Zhu-yao Jin, J. Q. You, Jun Jing·Apr 3, 2026
Within a unified framework, we reveal that the seemingly disparate control approaches for classical and quantum continuous-variable systems are interconnected via differential manifolds of the ancillary representations. For classical systems, the anc...
Open-source implementation of the anti-Hermitian contracted Schrödinger equation for electronic ground and excited states
Daniel Gibney, Anthony W Schlimgen, Jan-Niklas Boyn·Apr 2, 2026
Efficient simulation of strongly correlated electrons has become a routine tool in molecular electronic structure theory due to recent advances in approximate configuration interaction (CI) techniques. Nonetheless, the quantitative and predictive des...
Universal critical timescales in slow non-Hermitian dynamics
Giorgos Pappas, Diego Bautista Avilés, Luis E. F. Foa Torres +1 more·Apr 2, 2026
Non-Hermitian systems driven along slow parametric loops undergo non-adiabatic transitions whose outcome depends sensitively on the driving speed, yet no explicit formula has been available for the critical timescale $T_{\mathrm{cr}}$ at which these ...
Mechanism for scale-free skin effect in one-dimensional systems
Shu-Xuan Wang·Apr 2, 2026
Non-Hermitian skin effect (NHSE) is one of the most fascinating phenomena in non-Hermitian systems, which refers to enormous eigenstates localize at the boundary exponentially under open boundary condition (OBC). For typical NHSE, the localization le...
Constructing Fermionic Dynamics with Closed Moment Hierarchies
A. E. Teretenkov·Apr 1, 2026
We construct a broad class of completely positive maps and Go\-rini--Kossakowski--Sudarshan-Lindblad generators for fermionic systems induced by linear transformations of system and environment modes. For these maps, we derive explicit Heisenberg-pic...
Pricing Lookback Options on a Quantum Computer
F. Paquette, Tania Belabbas, Emmanuel Hamel +1 more·Apr 1, 2026
We develop a quantum algorithm to price discretely monitored lookback options in the Black-Scholes framework using imaginary time evolution. By rewriting the pricing PDE as a Schrodinger-type equation, the problem becomes the imaginary time evolution...
