Ground-state cooling of dispersively coupled optomechanical system in unresolved sideband regime via dissipatively coupled oscillator
Yu-Xiang Zhang, Shengjun Wu, Zeng-Bing Chen +1
In the optomechanical cooling of a dispersively coupled oscillator, it is only possible to reach the oscillator ground state in the resolved sideband regime, where the cavity-mode…
Contact geometric descriptions of vector fields on dually flat spaces and their applications in electric circuit models and nonequilibrium statistical mechanics
Shin-itiro Goto
Contact geometry has been applied to various mathematical sciences, and it has been proposed that a contact manifold and a strictly convex function induce a dually flat space that…
High-energy side-peak emission of exciton-polariton condensates in high density regime
Tomoyuki Horikiri, Makoto Yamaguchi, Kenji Kamide +9
In a standard semiconductor laser, electrons and holes recombine via stimulated emission to emit coherent light, in a process that is far from thermal equilibrium. Exciton-polarito…
Influence of pulse width and detuning on coherent phonon generation
Kazutaka G. Nakamura, Yutaka Shikano, Yosuke Kayanuma
We investigated the coherent phonon generation mechanism by irradiation of an ultrashort pulse with a simple two-level model. Our derived formulation shows that both impulsive stim…
Quadratic Fermi Node in a 3D Strongly Correlated Semimetal
Takeshi Kondo, M. Nakayama, R. Chen +18
Strong spin-orbit coupling fosters exotic electronic states such as topological insulators and superconductors, but the combination of strong spin-orbit and strong electron-electro…
Titania may produce abiotic oxygen atmospheres on habitable exoplanets
Norio Narita, Takafumi Enomoto, Shigeyuki Masaoka +1
The search for habitable exoplanets in the Universe is actively ongoing in the field of astronomy. The biggest future milestone is to determine whether life exists on such habitabl…
Classical Dynamics of Free Electromagnetic Laser Pulses
S. Goto, R. W. Tucker, T. J. Walton
We discuss a class of exact finite energy solutions to the vacuum source-free Maxwell field equations as models for multi- and single cycle laser pulses in classical interaction wi…
Advantages of nonclassical pointer states in postselected weak measurements
Yusuf Turek, W. Maimaiti, Yutaka Shikano +2
We investigate, within the weak measurement theory, the advantages of non-classical pointer states over semi-classical ones for coherent, squeezed vacuum, and Schröinger cat states…
Concatenated Composite Pulses Applied to Liquid-State Nuclear Magnetic Resonance Spectroscopy
Masamitsu Bando, Tsubasa Ichikawa, Yasushi Kondo +3
The error-robust and short composite operations named ConCatenated Composite Pulses (CCCPs), developed as high-precision unitary operations in quantum information processing (QIP),…
Quantum chemistry beyond Born-Oppenheimer approximation on a quantum computer: a simulated phase estimation study
Libor Veis, Jakub Višňák, Hiroaki Nishizawa +2
We present an efficient quantum algorithm for beyond-Born-Oppenheimer molecular energy computations. Our approach combines the quantum full configuration interaction method with th…
Influences of quantum mechanically mixed electronic and vibrational pigment states in 2D electronic spectra of photosynthetic systems: Strong electronic coupling cases
Yuta Fujihashi, Graham R. Fleming, Akihito Ishizaki
In 2D electronic spectroscopy studies, long-lived quantum beats have recently been observed in photosynthetic systems, and it has been suggested that the beats are produced by quan…
Impact of environmentally induced fluctuations on quantum mechanically mixed electronic and vibrational pigment states in photosynthetic energy transfer and 2D electronic spectra
Yuta Fujihashi, Graham R. Fleming, Akihito Ishizaki
Recently, nuclear vibrational contribution signatures in 2D electronic spectroscopy have attracted considerable interest, in particular as regards interpretation of the oscillatory…
A Conformational Search Method for Protein Systems Using Genetic Crossover and Metropolis Criterion
Yoshitake Sakae, Tomoyuki Hiroyasu, Mitsunori Miki +2
Many proteins carry out their biological functions by forming the characteristic tertiary structures. Therefore, the search of the stable states of proteins by molecular simulation…
