Towards the phase diagram of cold and dense heavy QCD [PDF]
The thermodynamics of QCD with sufficiently heavy dynamical quarks can be described by a three-dimensional Polyakov loop effective theory, obtained after a truncated character and hopping expansion.

Testing the criterion for correct convergence in the complex Langevin method
Recently the complex Langevin method (CLM) has been attracting attention as a solution to the sign problem, which occurs in Monte Carlo calculations when the effective Boltzmann weight is not real positive.

We consider three-flavor chiral perturbation theory (χPT) at zero temperature and nonzero isospin (μ I ) and strange (μ S ) chemical potentials. The effective potential is calculated to next-to-leading order (NLO) in the π ± -condensed phase, the K ...

Exploring the phase diagram of QCD with complex Langevin simulations [PDF]
I Real Langevin simulations converge to the expected result. For gauge theories simulations with complexified degrees of freedom are no longer in a compact group, SU(3)→ SL(3,C), and convergence is no longer guaranteed and needs to be checked [2].

Exploring the phase diagram of sextet QCD [PDF]
As a follow up to the previous talk about the beta function of SU(3) gauge theory with Nf=2 symmetric representation (clover) fermions [arXiv:0809.2885 [hep-lat]], we describe our explorations of the beta-kappa plane, away from the massless limit. Our simulations are mostly done on lattices of length L=8 and 12.

Infrared Photovoltaic-Battery Hybrid Systems Enabled by Colloidal Quantum Dots. [PDF]
Photovoltaic–battery (PV/B) hybrid systems are key for sustainable energy but face cost and efficiency limits. Colloidal quantum dots (CQDs) enable low‐cost near‐infrared light harvesting, surpassing silicon and III–V PVs. This review analyzes CQD properties, their roles in NIR PVs and batteries, and synthesizes current research to highlight progress ...

Magnetic catalysis and inverse catalysis for heavy pions
We investigate the QCD phase diagram for nonzero background magnetic fields using first-principles lattice simulations. At the physical point (in terms of quark masses), the thermodynamics of this system is controlled by two opposing effects: magnetic ...

Phase diagram of QCD at finite temperature and chemical potential from lattice simulations with dynamical Wilson quarks [PDF]
We present the first results for lattice QCD at finite temperature T and chemical potential {mu} with four flavors of Wilson quarks. The calculations are performed using the imaginary chemical potential method at {kappa}=0,0.001,0.15,0.165,0.17 and 0.25,

QCD Phase Diagram with Imaginary Chemical Potential
We report our recent results on the QCD phase diagram obtained from the lattice QCD simulation. The location of the phase boundary between hadronic and QGP phases in the two-flavor QCD phase diagram is investigated.

Combining the complex Langevin method and the generalized Lefschetz-thimble method
The complex Langevin method and the generalized Lefschetz-thimble method are two closely related approaches to the sign problem, which are both based on complexification of the original dynamical variables. The former can be viewed as a generalization of
