Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach
Contributions to Plasma Physics, EarlyView.ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Physical renormalization condition for the quark-mixing matrix
, 2004 We investigate the renormalization of the quark-mixing matrix in the Electroweak Standard Model. We show that the corresponding counterterms must be gauge independent as a consequence of extended BRS invariance.

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem
Contributions to Plasma Physics, EarlyView.ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

Fate of surface gaps in magnetic topological insulators
JPhys MaterialsIn magnetic topological insulators, the surface states can exhibit a gap due to the breaking of time-reversal symmetry. Various experiments, while suggesting the existence of the surface gap, have raised questions about its underlying mechanism in the ...

Renormalization group invariance in pionless effective field theory for the NN system
, 2010 We consider the NN interaction in pionless effective field theory (EFT) up to next-to-next-to-leading order (NNLO) and use a recursive subtractive renormalization scheme to describe NN scattering in the 1S0 channel.

Renormalization scheme dependence with renormalization group summation [PDF]
Physical Review D, 2015 We consider all radiative corrections to the total electron-positron cross section showing how the renormalization group equation can be used to sum the logarithmic contributions in two ways. First of all, one can sum leading-log etc. contributions. A second summation shows how all logarithmic corrections can be expressed in terms of log-independent ...

Dynamics of Dissipative Cavity Solitons in a Lattice Trap
Laser &Photonics Reviews, EarlyView.This work presents a generalized analytical model elucidating the dynamics of dissipative solitons in dual‐frequency‐pumped Kerr‐nonlinear cavities. The unified framework predicts new phenomena and expounds hitherto unexplained experiments covering hysteresis, Arnold tongues, and existence region of all‐optical dissipative time crystals.
