Fractional Shapiro steps in a Cavity-Coupled Josephson ring condensate
The Josephson effect presents a fundamental example of macroscopic quantum coherence as well as a crucial enabler for metrology (e.g. voltage standard), sensing (e.g. Superconducting Quantum Interference Device) and quantum information processing (Josephson qubits). Recently, there has been a major renewal of interest in the effect, following its observation in Bose, Fermi, and dipolar atomic condensates, in exciton-polariton condensates, and in momentum space. We present theoretically a nondes…

Local and Global Reciprocity in Orbital-Charge-Coupled Transport
The coupled transport of charge and orbital angular momentum (OAM) lies at the core of orbitronics. Here, we examine the reciprocal relation in orbital-charge-coupled transport in thin films, treating bulk and surface contributions on equal footing. We argue that the conventional definition of orbital current is ill-defiled, as it violates reciprocity due to the nonconservation of OAM. This issue is resolved by adopting the so-called \emph{proper} orbital current, which is directly linked to or…

It seems like, again, just following the plain logic of the Constitution and Declaration of Independence (which, again, I do not subscribe to), that every law passed under Trump, every supreme court justice appointment by Trump, every supreme court ruling by Trump appointed justices, all the illegal firing, etc, must all, necessarily, be null and void.
And if not following from the insurrection act, or from the oath of office, then following from the Declaration of Independence itself. The logic here being that a constitution is a contract between the people and their government, which the later upholds in order to maintain its legal status. The violation of said laws by the government violates "consent of the governed" (which, again, I have issues with the concept entirely but we're just going to ignore that) and therefore nullifies the authority of that government, granting " the right of the people to alter or to abolish it."
That seems a lot like the hard reset some folks have been looking for. Given that existing flaws allowed this state to be reached, it would also be necessary for the true authority to correct those mistakes before assuming authority that derives from these principles.
Now, personally, I don't subscribe to any of this logic but it's interesting to explore, as an outsider, where the logic goes.

Ferroelectricity in 6 Angstrom-Thick Two-dimensional Ga$_2$O$_3$

Ferroelectricity in 6 Angstrom-Thick Two-dimensional Ga$_2$O$_3$
Atomic-scale ferroelectric thin films hold great promise for high-density, low-power applications but face stability and voltage scaling challenges at extreme thinness. Here, we demonstrate ferroelectricity in single-crystalline two-dimensional (2D) Ga$_2$O$_3$, an ultra-wide-bandgap semiconductor, at just 6 angstrom thickness, exhibiting exceptional retention and thermal stability. We show that epitaxial beta-Ga$_2$O$_3$ can be exfoliated down to a half-unit cell thickness via a self-limiting …

Simulation of irradiated hybrid planar pixels modules at fluences expected at HL-LHC
Signal loss is the main limitation on tracking/vertexing performance due to radiation damage effect to hybrid pixel detectors when irradiated at fluences expected at High Luminosity LHC (HL-LHC). It is important to have reliable predictions on the charge collection performance after irradiation in order to predict operational voltage values and test tracking algorithms robustness. In this paper the validation of combined TCAD and Monte Carlo simulations of hybrid silicon planar pixels sensors w…

Coercive Field Reduction in Ultra-thin Al1-XScXN via Interfacial Engineering with a Scandium Electrode
Aluminum scandium nitride (AlScN) ferroelectrics are promising for next-generation non-volatile memory applications due to their high remnant polarization as well as fast switching and scalability to nanometer thicknesses. As device dimensions shrink, the coercive field in ultra-thin ferroelectric films increases, which challenges low-voltage operation. We demonstrate that interfacial engineering through bottom electrode selection and strain management reduces this coercive field increase and i…

Roles of Non-switchable Domains and Internal Bias in Electrocaloric and Pyroelectric effects
Solid-state cooling and energy harvesting via pyroelectric effect (PEE) and electrocaloric effect (ECE) in ferroelectric thin films could be enhanced beyond their intrinsic ferroelectric response by exploiting the recently observed direction-dependent enhancement of the PEE; however, its microscopic origin remains unknown. Herein, we report direct hysteresis measurements of pyrocurrent ($I_{\rm p}$) and ECE-induced temperature change versus bias voltage in 1-$μ$m-thick Pb(Zr$_{0.65}$Ti$_{0.35}…
