This paper demonstrates that Purcell engineering of critical coupling in tailored cavity architectures can dramatically enhance the absorption of weak interlayer excitons in MoS2 bilayers and trilayers, boosting their optical interaction strength to levels comparable to dominant intralayer excitons.
This paper demonstrates a cavity-assisted dynamic nuclear polarization mechanism using the Purcell effect to enhance bismuth donor nuclear spin polarization in silicon at millikelvin temperatures, achieving a fourfold cumulative enhancement through a cycle of microwave pulses and radiative relaxation.
This paper identifies the origin of the frequency-noise floor in nanomechanical resonators as thermal tension fluctuations governed by structural damping, demonstrating that dissipation dilution via high tensile stress effectively suppresses this noise and extends the sensor's useful averaging time.
This paper demonstrates that applying slow parametric modulation to a resonantly driven nonlinear graphene resonator breaks adiabatic tracking of the rotating-frame landscape, thereby inducing nonadiabatic instabilities, period doubling, and chaos that can be predicted by slow-variable theory and Melnikov analysis.
This study utilizes cryogenic scattering-type scanning near-field optical microscopy (s-SNOM) to directly correlate local strain profiles with excitonic energy shifts in monolayer WSe, revealing that nano-indentation causes compressive strain and monolayer damage while patterned substrates induce tensile strain, thereby clarifying the complex strain-mediated origins of single-photon emission.
This paper generalizes Beenakker's transmission representation of Josephson free energy beyond the short-junction limit to finite temperatures, proving a specific bound on the quartic-to-quadratic coefficient ratio and disproving a previous conjecture through a counterexample, with all mathematical derivations formally verified using the Lean proof assistant.
This paper presents the first complete first-principles solution of the non-Abelian quantum Hall problem at using a momentum-resolved neural-network variational wave function, demonstrating that strong Landau level mixing favors the anti-Pfaffian state and confirming the emergence of Ising-type non-Abelian anyons with quantum dimension .
This paper introduces a graph-theoretic analytical framework and a Generalized Equilibrium Propagation algorithm that enables the exact, local training of energy-efficient analog resistor networks using only output-layer readouts, while demonstrating that updating a subset of resistances maintains strong performance.
This study demonstrates the trapping and controlled manipulation of single anyons in a graphene-based quantum Hall dot, revealing complex orbital shell-filling behaviors and experimentally confirming the existence of a significant anyon binding energy that leads to the pairing of fractional charges.
This paper introduces an improved quantitative modeling strategy that utilizes alchemical decoupling and Gibbs free energy of solvation to accurately calibrate potential energy surfaces, thereby resolving discrepancies with experimental results by predicting significantly higher desolvation barriers and revealing that solvent monolayers often persist between aggregated 2D material layers.
