Phase transitions in first-detection statistics of monitored long-range quantum walks

Sayan Roy, Shamik Gupta, Giovanna Morigi +1

In a quantum walk, the first-detection return probability (FDRP) characterizes salient features, determining whether the quantum walk is transient or recurrent. We study the FDRP o…

Quantization of the classical Mpemba effect

Jannis Melles, Hartmut Löwen, Benno Liebchen +4

The Mpemba effect refers to the counterintuitive phenomenon that an initially hot system can freeze faster than an initially warm one. Recent years have brought major advances in b…

Anomalous Mean-Squared Displacement in Quantum Active Matter from a Wigner Phase-Space Framework

Sangyun Lee, Yehor Tuchkov, Alexander P. Antonov +4

Active matter is driven out of equilibrium by a local influx of energy. While classical active matter has been extensively studied, the extension of active matter concepts to quant…

Time complexity of a monitored quantum search with resetting

Emma C. King, Sayan Roy, Francesco Mattiotti +3

Searching a database is a central task in computer science and is paradigmatic of transport and optimization problems in physics. For an unstructured search, Grover's algorithm pre…

Modeling dissipation in quantum active matter

Alexander P. Antonov, Sangyun Lee, Benno Liebchen +5

Active matter is characterized by a constant influx and dissipation of energy that gives rise to directed motion. Dissipation requires interactions with an external environment, su…

Causality, localization, and universality of monitored quantum walks with long-range hopping

Sayan Roy, Shamik Gupta, Giovanna Morigi

A powerful strategy to accelerate quantum-walk-based search algorithms leverages on resetting protocols, where a detector monitors a target site and the evolution of the walker is…
