Quantum critical dynamics in a 5000-qubit programmable spin glass [PDF]
Nature, 2023, 2022 Experiments on disordered alloys suggest that spin glasses can be brought into low-energy states faster by annealing quantum fluctuations than by conventional thermal annealing. Due to the importance of spin glasses as a paradigmatic computational testbed, reproducing this phenomenon in a programmable system has remained a central challenge in quantum ...

Proposal of a Checking Parameter in the Simulated Annealing Method Applied to the Spin Glass Model [PDF]
, 2015 We propose a checking parameter utilizing the breaking of the Jarzynski equality in the simulated annealing method using the Monte Carlo method. This parameter is based on the Jarzynski equality.

Comparing Monte Carlo methods for finding ground states of Ising spin glasses: population annealing, simulated annealing and parallel tempering [PDF]
Phys. Rev. E 92, 013303 (2015), 2014 Population annealing is a Monte Carlo algorithm that marries features from simulated annealing and parallel tempering Monte Carlo. As such, it is ideal to overcome large energy barriers in the free-energy landscape while minimizing a Hamiltonian. Thus, population annealing Monte Carlo can be used as a heuristic to solve combinatorial optimization ...

Plastic versus glass capillaries for rapid-cycle PCR
BioTechniques, 2008 Rapid-cycle PCR uses fast temperature transitions and minimal denaturation and annealing times of “0” s to complete 30 cycles in 10 to 30 min. The most popular platform amplifies samples in glass capillaries arranged around a carousel with circulating ...

Atomic Origin of Annealing Embrittlement in Metallic Glasses [PDF]
arXiv, 2022 An atomistic understanding of annealing embrittlement is a longstanding issue for metallic glasses, which is still lacking due to the insurmountable gap between the thermal history of atomic models and laboratory-made samples. Here, based on a thermal-cycling annealing method that can vary the effective quenching rate over ten orders of magnitude, we ...
