Fermionic Quantum Approximate Optimization Algorithm
Takuya Yoshioka, Keita Sasada, Yuichiro Nakano +1
Quantum computers are expected to accelerate solving combinatorial optimization problems, including algorithms such as Grover adaptive search and quantum approximate optimization a…
Conservation of Fractional Mean Energy in Dissipative Gases
Keisuke Fujii
I show a nontrivial functional giving a conservation quantity in the collisional energy cascade of dissipative Maxwell gases: a fractional-calculus extension of the mean energy. Th…
Bulk viscosity of resonantly interacting fermions in the quantum virial expansion
Keisuke Fujii, Tilman Enss
We consider two-component fermions with a zero-range interaction both in two and three dimensions and calculate the bulk viscosity for an arbitrary scattering length in the high-te…
Universal van der Waals Force Between Heavy Polarons in Superfluids
Keisuke Fujii, Masaru Hongo, Tilman Enss
We investigate the long-range behavior of the induced Casimir interaction between two spinless heavy impurities, or polarons, in superfluid cold atomic gases. With the help of effe…
A Simple Data-Driven Level Finding Method of Quantum Many-Body Systems based on Statistical Outlier Detection
Kazuaki Hongu, Keisuke Fujii
We report a simple and pure data-driven method to find new energy levels of quantum many-body systems only from observed line wavelengths. In our method, all the possible combinati…
Hall viscosity in the A-phase of superfluid He
Takuya Furusawa, Keisuke Fujii, Yusuke Nishida
We construct the effective field theory for the A-phase of superfluid He up to the next-to-leading order in the derivative expansion. To this end, we gauge the internal global…
