Spin transport between polarized Fermi gases near the ferromagnetic phase transition

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Tingyu Zhang, Daigo Oue, Hiroyuki Tajima, Mamoru Matsuo, Haozhao Liang | Summary: We theoretically study the spin current between two polarized Fermi gases with repulsive interactions near the itinerant ferromagnetic phase transition. We consider a two-terminal model where the left reservoir is fixed to be fully polarized […]

N-spherical functors and categorification of Euler’s continuants

Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Tobias Dyckerhoff, Mikhail Kapranov, Vadim Schechtman, , | Summary: Euler’s continuants are universal polynomials expressing the numerator and denominator of a finite continued fraction whose entries are independent variables. We introduce their categorical lifts which are natural complexes (more precisely, coherently commutative cubes) of functors involving compositions […]

Thermodynamic behavior of correlated electron-hole fluids in van der Waals heterostructures

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Ruishi Qi, Andrew Y. Joe, Zuocheng Zhang, Yongxin Zeng, Tiancheng Zheng | Summary: Coupled two-dimensional electron-hole bilayers provide a unique platform to study strongly correlated Bose-Fermi mixtures in condensed matter. Electrons and holes in spatially separated layers can bind to form interlayer excitons, composite Bosons expected […]

Axion Insulator State in Hundred-Nanometer-Thick Magnetic Topological Insulator Sandwich Heterostructures

Kavli Affiliate: Ke Wang | First 5 Authors: Deyi Zhuo, Zi-Jie Yan, Zi-Ting Sun, Ling-Jie Zhou, Yi-Fan Zhao | Summary: An axion insulator is a three-dimensional (3D) topological insulator (TI), in which the bulk maintains the time-reversal symmetry or inversion symmetry but the surface states are gapped by surface magnetization. The axion insulator state has […]
