Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Revisiting the Immirzi parameter: Landauer’s principle and alternative entropy frameworks in loop quantum gravity

open access: yesEuropean Physical Journal C: Particles and Fields
This paper investigates the implications from area quantization in Loop Quantum Gravity, particularly focusing on the application of the Landauer principle – a fundamental thermodynamic concept establishing a connection between information theory and ...

Exponentially Adiabatic Switching in Quantum-Dot Cellular Automata

open access: yesJournal of Low Power Electronics and Applications, 2018
We calculate the excess energy transferred into two-dot and three-dot quantum dot cellular automata systems during switching events. This is the energy that must eventually be dissipated as heat.

Three types of Landauer’s erasure principle: a microscopic view

open access: yesThe European Physical Journal Plus, 2023
AbstractAn important step to incorporate information in the second law of thermodynamics was done by Landauer, showing that the erasure of information implies an increase in heat. Most attempts to justify Landauer’s erasure principle are based on thermodynamic argumentations.

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

open access: yesAdvanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Thermal‐Driven Diode Polarity Switching From Competing Helical Superconducting States in WTe2/α‐Fe2O3 Heterostructures

open access: yesAdvanced Materials, EarlyView.
A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

„Nur manchmal in Theatern springt es uns entgegen“: Ernst Tollers wirken in der Münchener Räterepublik (1919) als gelebte Utopie und deren Verarbeitung im Drama Masse Mensch. „Nur manchmal in Theatern springt es uns entgegen“: Ernst Toller’s involvement in the Munich Räterepublik (1919) as ‚realized‘ utopia and its influence on his drama Masse Mensch [PDF]

open access: yesLiteratūra (Vilnius), 2008
My article gives a description of political thought included in Toller’s play Masse Mensch (1921) and the government-conceptions it contains. The analysis tries an approach on that problem focusing the historic prototype of Tollers main character Sonja ...

Thermodynamic cost of erasing information in finite time

open access: yesPhysical Review Research, 2023
The Landauer principle sets a fundamental thermodynamic constraint on the minimum amount of heat that must be dissipated to erase one logical bit of information through a quasistatically slow protocol.

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...
