This paper demonstrates that specific three-dimensional topological phases function as acoustic diodes through nonlinear odd acoustoelastic effects, where the resulting anomalous second-harmonic generation and rectification are uniquely characterized by the momentum-space nonmetricity tensor, thereby completing the classification of quantum geometric observables in the quadratic response regime and offering new avenues for topological engineering.
This dissertation details the development of resonator-based dispersive microwave sensing techniques and a low-noise cryogenic microwave source to enable qubit readout for floating electrons on both liquid helium and solid neon substrates.
This study investigates the superconducting properties of transition metal dichalcogenide monolayers proximitized by a conventional -wave superconductor, revealing that their multiorbital nature and strong Ising spin-orbit coupling induce complex hybridization gaps and robust mixed spin-triplet pair correlations comparable in magnitude to spin-singlet pairs, while Rashba coupling further introduces competing equal-spin triplet pairs.
This paper establishes a microscopic quantum-kinetic framework demonstrating that intrinsic nonlinear gyrotropic magnetic transport in two-dimensional systems is fundamentally governed by a distinct separation between Zeeman and spin-rotation quantum geometric tensors, thereby linking spin-resolved quantum geometry to novel nonlinear magnetic responses for future optoelectronic and spintronic applications.
This study demonstrates that superconductivity in full-shell InAs/EuS/Al nanowires is exclusively induced by the multi-domain magnetic texture of the EuS shell, enabling the reconfigurable and position-dependent control of superconducting regions via small external magnetic fields, which holds promise for applications in topological qubits and superconducting logic.
This paper provides a comprehensive pedagogical analysis of a dynamical Keldysh model for single-particle propagation in a non-Markovian Gaussian random field, deriving exact analytical results for Green's functions and self-energies, establishing combinatorial rules for Feynman diagrams, and discussing potential experimental realizations in quantum transport.
This paper introduces thermal analog computing, a novel paradigm that utilizes inverse-designed metastructures and heat conduction to perform highly accurate matrix-vector multiplications, thereby enabling energy-efficient information processing in thermally active environments.
This study demonstrates that topological insulators serve as more robust platforms for current-induced molecular dissociation than conventional metallic substrates like graphene, primarily due to the localized nature of their edge states and the enhancing effect of vacancy disorder on dissociative forces.
This study establishes nanomechanical calorimetry as a powerful tool for mapping the complete magnetic phase diagram of 2D Ising metamagnet CrI3, successfully identifying its tricritical and critical end points through specific heat and magnetic circular dichroism measurements in a 6-layer device.
Using the Random Phase Approximation, this study reveals that while bias-driven critical charge fluctuations in an interacting quantum dot can be described by an effective temperature, current fluctuations exhibit genuinely non-equilibrium behavior with a negative fluctuation-dissipation ratio, establishing current noise as a sensitive probe for non-equilibrium quantum phase transitions.
