Sign Competing Sources of Berry Curvature and Anomalous Hall Conductance Humps in Topological Ferromagnets

open access: yesAdvanced Electronic Materials, Volume 11, Issue 18, November 4, 2025.
Mechanism proposed for the humps in topological ferromagnet. a) Hysteresis loops of σxy in external uniaxial magnetic field Hz and b) Anomalous Hall conductivity σxy as a function of polar angle θ. Data for |h⃗|$|\vec{h}|$ = 3t and λR/t = 0.08. A, B, and C are the states of the 2D topological ferromagnets.

Two‐Time Approach to Past–Future Quantum Dynamics: Formalism and Applications

open access: yesAdvanced Physics Research, Volume 4, Issue 11, November 2025.
A two‐time extension of the past‐future quantum state formalism is presented, describing systems with forward‐ and backward‐evolving states at distinct times. Using this framework, two‐time weak values are defined and applied them to Berry phase, spontaneous decay, and dwell time.

What a State: Why the U.S. is Still Bad for Your Health (Policy)

open access: yesThe International Journal of Health Planning and Management, Volume 40, Issue 6, Page 1326-1334, November 2025.
ABSTRACT The second Trump administration's centrepiece legislation, the modestly‐named Big Beautiful Bill, passed by the House of Representatives and going through the Senate at time of writing, offers an opportunity to reflect upon how the U.S. state affects health policy and the prospects for equitable access to affordable healthcare.
