Giant bulk photovoltaic effect driven by the wall-to-wall charge shift in WS2 nanotubes

Nature Communications, 2022
We demonstrate that double-wall or multi-wall WS2 nanotubes can exhibit unexpectedly efficient bulk photovoltaic effect owing to its unique inter-wall charge-shifting excitations.

Intermixing‐Driven Surface and Bulk Ferromagnetism in the Quantum Anomalous Hall Candidate MnBi6Te10

Advanced Science, 2023
The recent realizations of the quantum anomalous Hall effect (QAHE) in MnBi2Te4 and MnBi4Te7 benchmark the (MnBi2Te4)(Bi2Te3)n family as a promising hotbed for further QAHE improvements. The family owes its potential to its ferromagnetically (FM) ordered

A new bulk-driven input stage design for sub 1-volt CMOS op-amps [PDF]

, 2006
This paper presents a new design approach for a rail-to-rail bulk-driven input stage using a standard single-well (n-well in this paper) CMOS technology. This input stage can provide nearly constant transconductance and constant slew rate over the entire

Glioblastoma cell fate is differentially regulated by the microenvironments of the tumor bulk and infiltrative margin

Cell Reports, 2023
Summary: Glioblastoma (GBM) recurrence originates from invasive margin cells that escape surgical debulking, but to what extent these cells resemble their bulk counterparts remains unclear.

Spatial fluctuation theorem [PDF]

, 2015
For non-equilibrium systems of interacting particles and for interacting diffusions in d dimensions, a novel fluctuation relation is derived. The theorem establishes a quantitative relation between the probabilities of observing two current values in ...

Hierarchy of many-body invariants and quantized magnetization in anomalous Floquet insulators

SciPost Physics, 2021
We uncover a new family of few-body topological phases in periodically driven fermionic systems in two dimensions. These phases, which we term correlation-induced anomalous Floquet insulators (CIAFIs), are characterized by quantized contributions to
