Chiral and Diquark condensates at large magnetic field in two-flavor superconducting quark matter
, 2009 We study the effect of a large magnetic field on the chiral and diquark condensates in a regime of moderately dense quark matter. Our focus is on the inter-dependence of the two condensates through non-perturbative quark mass and strong coupling effects, which we address in a 2-flavor Nambu-Jona-Lasinio (NJL) model. For magnetic fields $eB\lesssim 0.01$

Controllable Laser‐Induced Phase Transition in Multilayer 2H‐MoTe2 and its Raman Spectroscopy Study
Advanced Electronic Materials, EarlyView.This study demonstrates a straightforward laser irradiation method for inducing phase transitions in 2H‐MoTe₂. By optimizing laser parameters, multilayer 2H‐MoTe₂ encapsulated with h‐BN is successfully transformed into the single 1T' phase, confirmed by Raman spectroscopy.

Progress of Theoretical and Experimental PhysicsAbstract In this paper, the question of the influence of color superconductivity on the formation of a phase with condensation of charged pions in dense, chirally asymmetric quark matter is studied. We consider it within the framework of the massless Nambu–Jona-Lasinio (NJL) model with a diquark interaction channel at zero temperature ...

Formation of gapless phases of
Physical Review D, 2007 Electric and color neutral solutions, and the critical conditions for the formation of gapless color superconductors, are investigated in $K^0$ condensed color-flavor locked quark matter for nonzero strange quark mass. We show that as the strange quark mass increases, gapless modes for up-strange quark pairing occur first, followed by down-strange ...

Signatures of the Correlated‐Hopping Interaction in Non‐Linear Transport Through a Quantum Dot
Annalen der Physik, EarlyView.Non‐linear thermoelectric transport through a quantum dot is studied, in order to elucidate the signatures of so‐called correlated hopping. The line shapes of the differential conductance and the Seebeck coefficient as functions of gate voltage are clear indicators of this important interaction term.

Quantum Anomalies in Condensed Matter
Advanced Physics Research, EarlyView.Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

Orientation‐Dependent Upper Critical Magnetic Field and Density of State for Uranium Ditelluride
Advanced Physics Research, EarlyView.This study investigates the orientation‐dependent upper critical magnetic field (HC2) and the density of states (DOS) in the unconventional superconductor UTe2. These results reveal an anisotropic HC2, with distinct critical fields along different crystallographic axes, highlighting the role of electronic correlations and spin‐triplet pairing.

Advanced Physics Research, EarlyView.Interfacing ferroelectric PbZr0.2Ti0.8O3 with ultrathin Sr2IrO4 tunes the antiferromagnetic Mott insulator into a 2D correlated metal. Switching the ferroelectric polarization induces nonvolatile, reversible resistance modulation in Sr2IrO4. The magnetoresisance in the heterostructure reveals the intriguing interplay of interfacial lattice coupling ...
