Thermally Modulated Specular Phonon Transport in a High‐Debye‐Temperature Diamond Nanobeam
Advanced Science, EarlyView.Thermal transport in single‐crystal diamond nanobeams is measured from 140 to 300 K using electro‐thermal micro‐suspended structures. The thermal conductivity shows an increasing deviation from Boltzmann transport predictions assuming fully diffuse boundary scattering at lower temperatures.

Quantum criticality at cryogenic melting of polar bubble lattices
Nature Communications, 2023 Quantum fluctuations (QFs) caused by zero-point phonon vibrations (ZPPVs) are known to prevent the occurrence of polar phases in bulk incipient ferroelectrics down to 0 K.

Advanced Science, EarlyView.Hyperfine coupling to 29Si$^{29}{\rm Si}$ and 73Ge$^{73}{\rm Ge}$ nuclear spins limits hole spin‐qubit coherence in Ge heterostructures. We demonstrate device‐grade, nuclear‐spin‐free 70Ge$^{70}{\rm Ge}$/28Si70Ge$^{28}{\rm Si}^{70}{\rm Ge}$ quantum wells grown on industrial SiGe buffers with minimal use of enriched precursors.

Quantum annealing enhanced Markov-Chain Monte Carlo
Scientific ReportsIn this study, we propose quantum annealing-enhanced Markov Chain Monte Carlo (QAEMCMC), where QA is integrated into the MCMC subroutine. QA efficiently explores low-energy configurations and overcomes local minima, enabling the generation of proposal ...

Cluster Monte Carlo Algorithms for Dissipative Quantum Systems
, 2005 We review efficient Monte Carlo methods for simulating quantum systems which couple to a dissipative environment. A brief introduction of the Caldeira-Leggett model and the Monte Carlo method will be followed by a detailed discussion of cluster ...

Entanglement spectroscopy using quantum Monte Carlo [PDF]
Physical Review B, 2014 We present a numerical scheme to reconstruct a subset of the entanglement spectrum of quantum many body systems using quantum Monte Carlo. The approach builds on the replica trick to evaluate particle number resolved traces of the first n of powers of a reduced density matrix.
