Electrically Binary and Ternary Convertible CMOS Inverter and Logic Gate Using Complementary Field‐Effect Transistors Based on Vertically Stacked MoS2/WSe2 n‐/p‐ Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
In this work, a reconfigurable T‐CMOS inverter based on vertically stacked MoS2 and WSe2 MOSFETs with a gate‐tunable MoS2 resistor, enabling stable ternary logic, is demonstrated. The T‐CMOS inverter supports electrical switching between ternary and binary modes and is further extended to implement ternary NAND (NMIN) and NOR (NMAX) logic gates ...

Robustness of quantum chaos and anomalous relaxation in open quantum circuits

Nature Communications
Dissipation is a ubiquitous phenomenon that affects the fate of chaotic quantum many-body dynamics. Here, we show that chaos can be robust against dissipation but can also assist and anomalously enhance relaxation. We compute exactly the dissipative form

Ground-state Stabilization of Open Quantum Systems by Dissipation

, 2015
Control by dissipation, or environment engineering, constitutes an important methodology within quantum coherent control which was proposed to improve the robustness and scalability of quantum control systems.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Clean‐Limit 2D Superconductivity in a Thick Exfoliated Kagome Film

Advanced Functional Materials, EarlyView.
This study reports clean‐limit 2D superconductivity in a thick kagome system, analogous to the 3D case. It observes a drop in superfluid stiffness near the superconducting transition and a cusp‐like feature in the angular dependence of the upper critical field.

Simulating open-system molecular dynamics on analog quantum computers

Physical Review Research
Interactions of molecules with their environment influence the course and outcome of almost all chemical reactions. However, classical computers struggle to accurately simulate complicated molecule-environment interactions because of the steep growth of ...

Unveiling Phonon Contributions to Thermal Conductivity and the Applicability of the Wiedemann—Franz Law in Ruthenium and Tungsten Thin Films

Advanced Functional Materials, EarlyView.
Thermal transport in Ru and W thin films is studied using steady‐state thermoreflectance, ultrafast pump–probe spectroscopy, infrared‐visible spectroscopy, and computations. Significant Lorenz number deviations reveal strong phonon contributions, reaching 45% in Ru and 62% in W.

Observation of quantum-classical transition behavior of LGI in a dissipative quantum gas

Physical Review Research
The Leggett-Garg inequality (LGI) is a powerful tool for distinguishing between quantum and classical properties in studies of macroscopic systems.

Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals

Advanced Functional Materials, EarlyView.
In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Stochastic semi-classical description of sub-barrier fusion reactions

EPJ Web of Conferences, 2011
A semi-classical method that incorporates the quantum effects of the low-lying vibrational modes is applied to fusion reactions. The quantum effect is simulated by stochastic sampling of initial zero-point fluctuations of the surface modes.
