Enabling the bulk photovoltaic effect in centrosymmetric materials through an external electric field

This paper presents a practical approach using a static out-of-plane electric field to dress Wannier-interpolated Hamiltonians, demonstrating how this method enables and tunes bulk photovoltaic effects, including the emergence of shift currents in centrosymmetric 2D materials like MoS $_2$ , by explicitly modifying orbital hybridization and band dispersion beyond perturbative treatments.

Higher-Dimensional Information Lattice: Quantum State Characterization through Inclusion-Exclusion Local Information

This paper generalizes the one-dimensional information lattice to higher-dimensional geometries by introducing an inclusion-exclusion principle to uniquely assign local information to lattice vertices, thereby enabling the characterization of diverse quantum many-body states through position- and scale-resolved features such as localization lengths, critical exponents, and topological signatures.

Topological Boundary Time Crystal Oscillations

This paper demonstrates that collective spin boundary time crystals exhibit robust, universal oscillations due to emergent topological winding numbers in operator space that enforce spectral delocalization and non-reciprocal transport, drawing a direct connection to non-Hermitian skin effects.

Ultrafast Band-Gap Renormalization in Bilayer Graphene

Using femtosecond time- and angle-resolved photoemission spectroscopy, this study demonstrates that photoinduced interlayer charge transfer and hot-carrier-enhanced screening in a silver-bilayer graphene heterostructure enable ultrafast, reversible control of the electronic band structure through transient band-gap opening and closing.

Modeling of a magnetic field sensor based on spin Hall magnetoresistance

This paper presents a comprehensive multiphysics model, validated by experiments on Pt/CoFeB and Ta/CoFeB bilayers, to optimize the design and performance of Spin Hall Magnetoresistance-based magnetic field sensors in Wheatstone bridge configurations by accounting for complex interplays between SMR, AMR, and SOT effects.

Nanoscale defects as probes of time reversal symmetry breaking

This paper proposes using Nitrogen Vacancy (NV) centers as sensitive probes to detect time-reversal symmetry breaking in low-dimensional conductors by measuring the difference in spin relaxation rates, a technique that can determine Hall viscosity and distinguish chiral superconducting states, such as those in twisted BSCCO flakes.

Ferroaxial order of the monolayer ice in martyite

This study reveals that monolayer ice confined within the mineral martyite undergoes a disorder-order transition below 200 K, forming hydrogen-bonded toroidal hexamers that establish a ferroaxial order, thereby elucidating the ground state of two-dimensional ice.

Odd relaxation in three-dimensional Fermi liquids

This paper demonstrates that isotropic three-dimensional Fermi liquids exhibit a hierarchy of long-lived, non-hydrodynamic modes where odd-parity relaxation is significantly slower than even-parity relaxation due to Pauli blocking and interaction effects, a phenomenon previously thought unique to two dimensions.

Floquet multiple exceptional points with higher-order skin effect

This paper investigates periodically driven open quantum systems in microcavities, demonstrating that a quenched driving protocol enables the controlled creation and annihilation of multiple Floquet exceptional points characterized by quantized winding numbers, while simultaneously inducing a higher-order skin effect with modes localized at both edges and corners.
