Photon production in heavy ion reactions

Journal of Physics: Conference Series, 2005
A review on experimental results of photon production in heavy ion reactions is given. Measurements using inclusive photons are discussed. Some developments in the theoretical description of direct photon production are reviewed. The measurement of direct photons in heavy ion reactions from the WA98 Collaboration is discussed and compared to ...

Unlocking Multi‐Valley Energy Pockets and Interface‐Induced Phonon Filtering in InSb Thermoelectrics by Reaction‐Driven Interface Engineering

Advanced Functional Materials, EarlyView.
InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...

Statistical and dynamical modeling of heavy-ion fusion–fission reactions

Physics Letters B, 2018
A modified statistical model and a four dimensional dynamical model based on Langevin equations have been used to simulate the fission process of the excited compound nuclei 207At and 216Ra produced in the fusion 19F + 188Os and 19F + 197Au reactions ...

Hadron ratio fluctuations in heavy-ion collisions

, 2012
The first measurement of the fluctuation of the kaon-to-proton ratio in relativistic heavy-ion collisions is presented. This thesis details the analysis procedure for identifying kaons and protons using the NA49 experiment at CERN-SPS and discusses the ...

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

Advanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Signatures of quark gluon plasma formation in high-energy heavy ion collisions : a critical review

, 2005
Ultra-relativistic heavy ion collisions offer the unique opportunity to probe highly excited dense nuclear matter under controlled laboratory conditions. The compelling driving force for such studies is the expectation that an entirely new form of matter

Microscopic approach to heavy-ion reactions [PDF]

, 2018
Heavy-ion reactions are affected by the nuclear structure of the reactants and other dynamical processes during the collision. Theoretical studies of such reactions lead to a clearer understanding of prohibitive mechanisms to heavy-ion ...

Hadronization in Heavy-Ion Reactions

, 1998
We present a model of fast hadronization of constituent quark matter in relativistic heavy ion collisions based on rate equations and capture cross sections in non-relativistic potential. We utilize a thermodynamically consistent approach with a non-ideal equation of state including correlation terms based on string phenomenology.

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance
