DOI: 10.1038/s41467-025-64763-7
Abstract: Coupled many-body quantum systems exhibit rich emergent physics with diverse stationary and dynamical behaviours. By engineering platforms with tunable and distinct coupling mechanisms, new insights emerge into the collective behaviour of coupled many body systems.… read more here.

DOI: 10.1080/00207721.2020.1857880
Abstract: ABSTRACT A finite-time geometric control of quadrotor has been proposed in this paper by representing the attitude using rotation matrices to avoid the singularities and ambiguities associated with Euler angles and quaternions. One of the… read more here.

DOI: 10.1103/physrevlett.134.188201
Abstract: The response of driven frustrated media stems from interacting hysteretic elements. We derive explicit mappings from networks of hysteretic springs to their abstract representation as interacting hysterons. These mappings reveal how the physical network controls… read more here.

DOI: 10.1109/jestpe.2025.3568674
Abstract: Linear controllers impose many limitations on the performance of dc–dc converters. Typically, the dynamics of these converters are averaged over a switching cycle and then linearized to create a linear time-invariant (LTI) system model, which… read more here.

DOI: 10.1109/lcsys.2022.3170866
Abstract: Studying structural properties of linear dynamical systems through invariant subspaces is one of the key contributions of the geometric approach to system theory. In general, a model of the dynamics is required in order to… read more here.

DOI: 10.1364/oe.447921
Abstract: We experimentally demonstrate that the next-nearest-neighbor-coupling (NNN-coupling) in an array of waveguides can naturally be negative. To do so, dielectric zig-zag shaped waveguide arrays are fabricated with direct laser writing (DLW). By changing the angle… read more here.
