Optimal low-rank compression of quantum dynamics
Hugo Mackay, Donghoon Kim, Tan Van Vu +1
Local quantum interactions generate dynamics in an exponentially large Hilbert space, yet locality and entanglement restrict the information that can spread and accumulate. Bounds…
Exact Fluctuation-Response Relations for Underdamped Langevin Dynamics
Tan Van Vu, Van Tuan Vo, Ruicheng Bao +1
Thermodynamic uncertainty relations connect current fluctuations to dissipation and, in certain settings, can emerge from underlying fluctuation-response relations. However, in und…
Predicting the conditions for observing the Mpemba effect
Yue Liu, Tan Van Vu, Raphaël Chétrite +2
The Mpemba effect, a counterintuitive phenomenon where a hotter system relaxes faster than a colder one, has been widely observed in various nonequilibrium systems. Despite this pr…
Hierarchy of entropy production and thermodynamic trade-off relations in non-Markovian systems
Ken Funo, Tan Van Vu, Keiji Saito
Non-Markovian dynamics arise when a system is coupled to a bath with finite correlation time, producing memory effects that can modify finite-time thermodynamic behavior. We study…
The Mpemba effect likes to hit a wall
Yue Liu, Tan Van Vu, Raphaël Chétrite +2
The original Mpemba effect refers to the idea that a macroscopic hot system cools faster than an initially colder one. In its microscopic and classical versions, the system is mode…
Universal Precision Limits in General Open Quantum Systems
Tan Van Vu, Ryotaro Honma, Keiji Saito
The intuition that the precision of observables is constrained by thermodynamic costs has recently been formalized through thermodynamic and kinetic uncertainty relations. While su…
Macroscopic Particle Transport in Dissipative Long-Range Bosonic Systems
Hongchao Li, Cheng Shang, Tomotaka Kuwahara +1
Dissipation in quantum many-body systems provides a more general and experimentally realistic perspective on particle transport than closed quantum systems. In this work, we determ…
Time-cost-error trade-off relation in thermodynamics: The third law and beyond
Tan Van Vu, Keiji Saito
Elucidating fundamental limitations inherent in physical systems is a central subject in physics. For important thermodynamic operations such as information erasure, cooling, and c…
Fidelity-dissipation relations in quantum gates
Tan Van Vu, Tomotaka Kuwahara, Keiji Saito
Accurate quantum computing relies on the precision of quantum gates. However, quantum gates in practice are generally affected by dissipative environments, which can significantly…
Optimal light cone for macroscopic particle transport in long-range systems: A quantum speed limit approach
Tan Van Vu, Tomotaka Kuwahara, Keiji Saito
Understanding the ultimate rate at which information propagates is a pivotal issue in nonequilibrium physics. Nevertheless, the task of elucidating the propagation speed inherent i…
Universal bounds on the performance of information-thermodynamic engine
Tomohiro Tanogami, Tan Van Vu, Keiji Saito
We investigate fundamental limits on the performance of information processing systems from the perspective of information thermodynamics. We first extend the thermodynamic uncerta…
Dissipation, quantum coherence, and asymmetry of finite-time cross-correlations
Tan Van Vu, Van Tuan Vo, Keiji Saito
Recent studies have revealed a deep connection between the asymmetry of cross-correlations and thermodynamic quantities in the short-time limit. In this study, we address the finit…
Geometric characterization for cyclic heat engines far from equilibrium

Considerable attention has been devoted to microscopic heat engines in both theoretical and experimental aspects. Notably, the fundamental limits pertaining to power and efficiency…
Topological Speed Limit
Tan Van Vu, Keiji Saito
Any physical system evolves at a finite speed that is constrained not only by the energetic cost but also by the topological structure of the underlying dynamics. In this Letter, b…
