A parity-breaking electronic nematic phase transition in the spin-orbit coupled metal Cd$_2$Re$_2$O$_7$ [PDF]
, 2017 Strong electron interactions can drive metallic systems toward a variety of well-known symmetry-broken phases, but the instabilities of correlated metals with strong spin-orbit coupling have only recently begun to be explored.

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces
Laser &Photonics Reviews, EarlyView.Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Gemeinschaft as the Lynchpin of Multilateralism: World Order and the Challenge of Multipolarity
Irish Studies in International Affairs, 2018 This paper seeks to understand the impact of the ongoing shifts in global politics upon the operation of international law. Specifically, it examines how a re-configuration of global political power from a ‘unipolar’ system dominated by the US to a ‘multipolar’ system in which the US will need to share the apex of the international political power ...

Testing the multipole structure and conservative dynamics of compact binaries using gravitational wave observations: The spinning case [PDF]
, 2019 In an earlier work [S. Kastha et al., PRD {\bf 98}, 124033 (2018)], we developed the {\it parametrized multipolar gravitational wave phasing formula} to test general relativity, for the non-spinning compact binaries in quasi-circular orbit. In this paper,

Reflections on Comparative Teaching in Public Administration
Public Administration and Development, EarlyView.ABSTRACT This article integrates our scholarly experience of teaching comparative public administration. In doing so, we offer a unique perspective as the co‐authors carry several diverse attributes, among them their countries of origin, current country in which they are teaching, and their academic experience.

Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit
Small, EarlyView.An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

Transverse multipolar light-matter couplings in evanescent waves
, 2016 We present an approach to study the interaction between matter and evanescent fields. The approach is based on the decomposition of evanescent plane waves into multipoles of well-defined angular momentum transverse to both decay and propagation ...

The Case of EU-China-Africa Relations [PDF]
, 2015 The world is becoming increasingly multipolar, mainly due to the economic and geopolitical rise of a group of emerging countries, particularly China. This international transition bears major consequences for the European Union (EU), which sees its ...

Technology for Whom and for What? A Global South View of Tech Diplomacy
Global Policy, EarlyView.ABSTRACT International politics is linked to its technical‐social character. Also, technology is socially constructed and thereby not entirely neutral or impartial. A tech‐driven geopolitical landscape has been a defining feature of contemporary world politics.

Normal gravity field in relativistic geodesy
, 2018 Modern geodesy is subject to a dramatic change from the Newtonian paradigm to Einstein's theory of general relativity. This is motivated by the ongoing advance in development of quantum sensors for applications in geodesy including quantum gravimeters ...
