This study demonstrates that while sulfur passivation creates a smoother and cleaner buried interface with superior material properties compared to argon milling or no treatment for Nb films on InP, all three surface preparation methods yield comparable microwave quality factors, suggesting that the devices are not primarily limited by dielectric loss at the buried interface.
This study demonstrates that microwave heating of black silicon at 2.45 GHz is significantly enhanced and orientation-dependent, with vertically aligned nano-needles achieving higher temperatures than flat silicon and tilted needles exhibiting a distinct delayed heating onset, all driven by thermally activated carrier generation and form birefringence effects.
This paper presents a non-linear quantum interferometer utilizing a granular aluminum superconducting circuit and a microwave cavity to surpass the shot noise limit, offering a promising tool for detecting dark matter, high-frequency gravitational waves, and astronomical masers.
This paper demonstrates that strong electron-phonon coupling in the Haldane-Holstein model at fractional filling can stabilize novel topological phases, including bosonic fractional Chern insulators and quantum anomalous Hall crystals, by generating effective interactions and binding electrons into pairs, thereby establishing electron-phonon coupling as a mechanism to induce rather than suppress topology.
This paper demonstrates that light decoherence, modeled as multichannel scattering in a Fabry-Perot microcavity, significantly alters the system's linear response by eroding cavity photon modes and suppressing the formation and spectral signatures of molecular polaritons.
This paper investigates a two-dimensional Rashba spin-orbit coupled nodal ring system to demonstrate how a parallel magnetic field induces anisotropic Berry curvature and a persistent nonlinear Hall effect that serves as a distinct probe for a topological phase transition, while also revealing an intraband sign-reversing integer quantum Hall effect driven by perpendicular fields.
This paper demonstrates that vacuum fluctuations in a cavity can drive a continuous phase transition in a quantum Hall ferromagnet at filling factor , destabilizing the uniform state to form novel "compact-core phases" characterized by inhomogeneous electron density and entanglement, with the transition order parameter directly probed by photon number.
This paper establishes a quantum geometric framework for gravitons in curved spacetime by linking their Wigner functions and stress-energy tensors to spinor-helicity formalism, thereby elucidating the roles of quantum metrics and connections in graviton transport and providing a unified geometric treatment for both bosonic and fermionic many-body systems.
This paper introduces a unified, contact-free moment formulation of linear-response transport theory that utilizes scalar sources to calculate transport coefficients directly from retarded moment-moment correlators, thereby eliminating the need for separate magnetization corrections and providing a gauge-invariant framework applicable to particle, thermal, and spin transport.
This paper demonstrates that linearly polarized light can activate the nonlinear Hall effect in topological insulators with warped Fermi surfaces by dynamically breaking threefold rotational symmetry to generate a tunable Berry curvature dipole, all while preserving time-reversal symmetry.
