Krylov Subspace Methods for Quantum Dynamics with Time-Dependent Generators
Kazutaka Takahashi, Adolfo del Campo
Krylov subspace methods in quantum dynamics identify the minimal subspace in which a process unfolds. To date, their use is restricted to time evolutions governed by time-independe…
Slow approach to adiabaticity in many-body non-Hermitian systems: the Hatano-Nelson Model
Léonce Dupays, Adolfo del Campo, Balázs Dóra
We explore the near adiabatic dynamics in a non-Hermitian quantum many-body system by investigating a finite-time ramp of the imaginary vector potential in the interacting Hatano-N…
Annealing Dynamics of Regular Rotor Networks: Universality and Its Breakdown
András Grabarits, Gaetano Sammartino, Adolfo del Campo
The spin-vector Monte Carlo model is widely used as a benchmark for the classicality of quantum annealers but severely restricts the time evolution. The spin-vector Langevin (SVL)…
Kibble-Zurek Mechanism and Beyond: Lessons from a Holographic Superfluid Disk
Chuan-Yin Xia, Hua-Bi Zeng, András Grabarits +1
The superfluid phase transition dynamics and associated spontaneous vortex formation with the crossing of the critical temperature in a disk geometry is studied in the framework of…
Universal Critical Holography and Domain Wall Formation
Tian-Chi Ma, Han-Qing Shi, Hai-Qing Zhang +1
Using holography, we study the universal scaling laws governing the coarsening dynamics of strongly coupled domain walls. Specifically, we studied the universal dependence of the l…
Quantum Chaos in Random Ising Networks
András Grabarits, Kasturi Ranjan Swain, Mahsa Seyed Heydari +3
We report a systematic investigation of universal quantum chaotic signatures in the transverse field Ising model on an Erdős-Rényi network. This is achieved by studying local spect…
A geometrical description of non-Hermitian dynamics: speed limits in finite rank density operators
Niklas Hörnedal, Oskar A. Prośniak, Adolfo del Campo +1
Non-Hermitian dynamics in quantum systems preserves the rank of the state density operator. Using this insight, we develop a geometric framework to describe its time evolution. In…
Transitionless Quantum Driving of the Tomonaga-Luttinger Liquid
Léonce Dupays, Adolfo del Campo
Shortcuts to adiabaticity (STA) make the fast preparation of many-body states possible, circumventing the limitations of adiabatic strategies. We propose a fast STA protocol for ge…
Decoherence rate in random Lindblad dynamics
Yifeng Yang, Zhenyu Xu, Adolfo del Campo
Open quantum systems undergo decoherence, which is responsible for the transition from quantum to classical behavior. The time scale in which decoherence takes place can be analyze…
Universal Vortex Statistics and Stochastic Geometry of Bose-Einstein Condensation
Mithun Thudiyangal, Adolfo del Campo
The cooling of a Bose gas in finite time results in the formation of a Bose-Einstein condensate that is spontaneously proliferated with vortices. We propose that the vortex spatial…
Exact Dynamics and Shortcuts to Adiabaticity in the Tomonaga-Luttinger Liquid
Léonce Dupays, Balázs Dóra, Adolfo del Campo
Controlling many-body quantum systems is a highly challenging task required to advance quantum technologies. Here, we report progress in controlling gapless many-body quantum syste…
Proposal for many-body quantum chaos detection
Adway Kumar Das, Cameron Cianci, Delmar G. A. Cabral +8
In this work, the term ``quantum chaos'' refers to spectral correlations similar to those found in the random matrix theory. Quantum chaos can be diagnosed through the analysis of…
