This paper establishes a direct link between angular momentum conservation in nonlinear optics and the electronic quantum geometry by demonstrating that nonlinear harmonic circular dichroism is proportional to the local Berry curvature, a relationship experimentally verified in an atomically thin semiconductor to enable all-optical control and read-out of this geometric property.
This study demonstrates that (101)-oriented RuO₂ thin films, a candidate altermagnet, exhibit giant room-temperature third-order electrical transport responses driven by simultaneous T-odd and T-even quantum geometric quantities, providing a robust method to detect Néel order and a versatile platform for quantum spintronic devices.
This paper introduces a multi-tone spectroscopy method combined with inverse reconstruction to experimentally quantify nonlinear coupling coefficients in nanomechanical resonators, successfully validating the approach by deriving accurate device-specific models for highly tensioned nanostrings that match finite element simulations.
This paper investigates how a single-mode photonic cavity modifies the topological phases of a one-dimensional Su-Schrieffer-Heeger chain in the off-resonant regime by deriving an effective interacting Hamiltonian and validating the resulting phase diagram through consistent agreement between winding number, bulk polarization, and edge correlation function markers.
This paper presents a full microscopic treatment of mesoscopic hybrid regions in Kitaev chains to derive analytical expressions for renormalized couplings and sweet-spot conditions, revealing that parity-crossings of spin-split Andreev bound states define optimal operating windows where Majorana zero modes are simultaneously well-localized and protected by a large excitation gap.
This paper demonstrates that strong electron-electron correlations in a Hubbard model with an odd number of electrons can spontaneously break time-reversal and mirror symmetries to induce a zero-field Josephson diode effect, establishing correlation as a distinct mechanism for nonreciprocal superconducting transport.
This paper studies the -symmetric Rabi model by deriving a mapping to a qubit-boson ring to propose realistic superconducting qubit implementations, and further extends this framework to realize the Potts model via a coupled chain of such systems.
This paper investigates the effects of long-range Coulomb interactions on a three-dimensional Berry-dipole semimetal using large- and -expansion renormalization-group analyses, revealing the emergence of a spatially anisotropic non-Fermi liquid with an enhanced Berry-dipole moment and providing scaling relations and observational criteria to distinguish this state from the original semimetal.
This paper proposes quantum capacitance as a novel equilibrium probe for detecting non-Hermitian physics in Dirac materials, demonstrating that in the weakly non-Hermitian regime, the quantum capacitance exhibits a universal divergence and Landau-level collapse as the system approaches an exceptional point due to hopping imbalance.
This study demonstrates that the ferromagnetic resonance dynamics in -FeO/NiFe heterostructures can be precisely and tunably modulated by manipulating interfacial exchange coupling through variations in temperature, magnetic field, and crystal orientation, offering a pathway for advanced, temperature-responsive spintronic devices.
