Krylov Complexity and Dynamical Phase Transition in the quenched LMG model
Pedro H. S. Bento, Adolfo del Campo, Lucas C. Céleri
Investigating the time evolution of complexity in quantum systems entails evaluating the spreading of the system's state across a defined basis in its corresponding Hilbert space.…
Kibble-Zurek Mechanism for Nonequilibrium Generation of Magnetic Monopoles in Spin Ices
Zhijie Fan, Adolfo del Campo, Gia-Wei Chern
The proliferation of topological defects is a common out-of-equilibrium phenomenon when a system is driven into a phase of broken symmetry. The Kibble-Zurek mechanism (KZM) provide…
Unitarity breaking in self-averaging spectral form factors
Apollonas S. Matsoukas-Roubeas, Mathieu Beau, Lea F. Santos +1
The complex Fourier transform of the two-point correlator of the energy spectrum of a quantum system is known as the spectral form factor (SFF). It constitutes an essential diagnos…
Large Deviations Beyond the Kibble-Zurek Mechanism
Federico Balducci, Mathieu Beau, Jing Yang +2
The Kibble-Zurek mechanism (KZM) predicts that the average number of topological defects generated upon crossing a continuous or quantum phase transition obeys a universal scaling…
Kibble-Zurek mechanism of Ising domains
Kai Du, Xiaochen Fang, Choongjae Won +5
The formation of topological defects after a symmetry-breaking phase transition is an overarching phenomenon that encodes rich information about the underlying dynamics. Kibble-Zur…
Universal defect density scaling in an oscillating dynamic phase transition
Wei-can Yang, Makoto Tsubota, Adolfo del Campo +1
Universal scaling laws govern the density of topological defects generated while crossing an equilibrium continuous phase transition. The Kibble-Zurek mechanism (KZM) predicts the…
Quantum Chaos and Coherence: Random Parametric Quantum Channels
Apollonas S. Matsoukas-Roubeas, Tomaž Prosen, Adolfo del Campo
The survival probability of an initial Coherent Gibbs State (CGS) is a natural extension of the Spectral Form Factor (SFF) to open quantum systems. To quantify the interplay betwee…
Structural phase transition and its critical dynamics from holography
Chuan-Yin Xia, Hua-Bi Zeng, Chiang-Mei Chen +1
We introduce a gravitational lattice theory defined in an AdS black hole background that provides a holographic dual description of the linear-to-zigzag structural phase transi…
Stochastic Operator Variance: an observable to diagnose noise and scrambling
Pablo Martinez-Azcona, Aritra Kundu, Adolfo del Campo +1
Noise is ubiquitous in nature, so it is essential to characterize its effects. Considering a fluctuating Hamiltonian, we introduce an observable, the stochastic operator variance (…
Shortcuts to Adiabaticity in Krylov Space
Kazutaka Takahashi, Adolfo del Campo
Shortcuts to adiabaticity provide fast protocols for quantum state preparation in which the use of auxiliary counterdiabatic controls circumvents the requirement of slow driving in…
Geometric Operator Quantum Speed Limit, Wegner Hamiltonian Flow and Operator Growth
Niklas Hörnedal, Nicoletta Carabba, Kazutaka Takahashi +1
Quantum speed limits (QSLs) provide lower bounds on the minimum time required for a process to unfold by using a distance between quantum states and identifying the speed of evolut…
