Geometric complexity in thermodynamics
Tan Van Vu, Keiji Saito
The third law of thermodynamics forbids cooling a physical system to absolute zero in a finite number of operational steps. Although this unattainability principle has been quantif…
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…
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…
Thermal Area Law in Long-Range Interacting Systems
Donghoon Kim, Tomotaka Kuwahara, Keiji Saito
The area law of the bipartite information measure characterizes one of the most fundamental aspects of quantum many-body physics. In thermal equilibrium, the area law for the mutua…
Prethermal inverse Mpemba effect
Koudai Sugimoto, Tomotaka Kuwahara, Keiji Saito
The inverse Mpemba effect is a counterintuitive phenomenon in which a system, initially in thermal equilibrium and prepared at different temperatures below that of the final equili…
Thermodynamic bounds and error correction for faulty coarse graining
Jann van der Meer, Keiji Saito
At the nanoscale, random effects govern not only the dynamics of a physical system but may also affect its observation. This work introduces a novel paradigm for coarse graining th…
